Change in aboveground biomass carbon stock following the establishment of exclosures on degraded lands in Tigray, Ethiopia
This dataset contains a vegetation inventory from a study in Ethiopia and these data represent the trees and shrubs found in the exclosures (see methods section). Aboveground biomass and carbon stocks were measured in three pools; i. e. aboveground biomass of woody plants, herbaceous vegetation and litter. A nested plot, with three sections was used in all land use types to assess the aboveground biomass of woody species, herbs and grasses, and litter. The size and shape of the main plot was fixed based on the diameter size and degree of homogeneity of the plant species sampled in that plot. Accordingly, two plot shapes of different sizes were selected; a rectangular plot of 1000 m2 (0.1 ha) for the E. globulus plantations (Ravindranath and Ostwald, 2008) and a square of 400 m2 (0.04 ha) for the exclosures and grazing lands (WBISPP, 2000). At the southwestern corner of each main plot, a sub-plot of 4 m2 was positioned for the biomass assessment of herbs and grasses. Within the 4 m2 plots, a sub-plot of 1 m2 was established randomly at one of the corners of the sub-plot, for the measurement of litter biomass. In each main plot located in the exclosures and grazing lands, diameter at stump height (DSH) (30 cm from the ground) and total height of all trees and shrubs were measured. Local names of all plant species were recorded and plant specimens mainly from the foliage were also collected for subsequent identification. Diameter at breast height (DBH) and total height (H) of each E. globulus tree found in the main plot were also measured. DBH and DSH were measured by using calipers graduated in mm. Total height was measured using a meter tape or a hypsometer, depending on the height of the plant. Altitude and coordinates of each plot center were taken using GPS. Average slope was also measured at each plot using a clinometer.

Terrestrial and limnic invertebrates systematic collection, NTNU University Museum
The terrestrial and liminic invertebrates systematic collection at the NTNU University Museum dates back to activities initiated by Bishop Johan Ernst Gunnerus in the 1760's and objects from Bjarne Lysholm’s collection of Coleoptera from around 1880-1939. The bulk of the collection dates from the 1960's and up to today and includes the Lepidoptera collection of Carl Fredrik Lühr and Runar Krogen, the Coleoptera collections of Karl Erik Zachariassen and Dagfinn Refseth. A recent acquisition of approximately 160 000 identified specimens came from Frode Ødegaard’s collection previously hosted at the Norwegian Institute for Nature Research. Today's collection covers most of the major groups of invertebrates with Lepidoptera, Coleoptera, Diptera and Hymenoptera as the largest parts of the collections (approximately 40 %, 20 %, 10 % and 7 % respectively in 2017). Some groups are overrepresented compared to others. This reflects the taxonomic expertise among the staff since the first regular employee in the 1840's and donations of private collections. The collection includes objects from all other continents except the Antarctica. Examples from other parts of the world are chironomids from America, Africa, Europe and Asia, a historic circumpolar collection of Coleoptera. Coleoptera from Central America, Australia, southern Europe, Africa and Papua New Guinea. There are also Lepidoptera from Malawi and terrestrial molluscs from Madeira, Cuba and some other countries.

Marine invertebrate collection NTNU University Museum
The marine invertebrate collections at the NTNU University Museum goes back to the activities initiated by Bishop Johan Ernst Gunnerus in the 1760's (Bakken et al. 2011). Only a handful specimens in the collection date back to this period. From around 1870 an exploration and mapping of marine environments in central Norway started, initially the Trondheimsfjord, but later also coastal areas outside the fjord. Sampling activities contributing preserved specimens have been at irregular intervals since the 1870s, and impact in number of objects and taxa represented has mainly been a result of several large projects. Apart from larger sampling programmes, small and single collecting activities has taken place over the period since the start. The collection holds about 120,000 records of most has been digitised. The geographic span of the records are mainly Norwegian waters. Within Norwegian waters a majority origins in the central part of Norway, including the 600 m deep Trondheimsfjord, and the costal areas outside the fjord. In addition there are samples from along the Norwegian coast, primarily north of the Trondheimsfjord, also representing the deep-sea areas in the Norwegian Sea, and from Svalbard. Samples from international marine environments are mainly from neighbouring Nordic countries. But also a number of samples from the Tristan da Cunha archipelago in the South Atlantic, resulting from the Norwegian Tristan da Cunha Expedition 1937-38. All animal phyla with known representing high number of taxa world-wide are represented, but it is obvious from the holdings that some groups are overrepresented compared to others. This reflects the taxonomic expertise among the staff since Vilhelm Storm started exploring the Trondheimsfjord in the1870s (Mork & Sneli 2011). Norwegian waters have been important for describing new species in the early days of natural history explorations, thus representing type localities for a range of marine species described from the 18th century onwards (Oug et al. 2014). The collections at NTNU University Museum holds several type specimens, including from Tristan da Cunha, which has been described in detail (Bakken 1999).

Pelagic Fish at the Barents Sea Polar Front in January 2024
### Study area This dataset is the result of sampling at five stations along a transect in the western Barents Sea. ### Time coverage The samples were collected between 7 January 2024 and 12 January 2024. ### Sampling Five pelagic trawl samples were collected with a Harstad pelagic trawl, which has an effective opening of 80 m2 when towed at ca. 3 knots. The mesh size of the inner liner of the cod end was 10 mm. The pelagic trawl was towed at ca. 3 knots for 20-30 min at the target depth and abundances were standardized by converting to catch per unit effort (expressed in kilograms per cubic meter). ### Sample analysis All organisms were identified to the nearest species or genus onboard. Capelin had a large size distribution, so individuals similar in length were sorted into approximate size classes (small, medium, and large). The total number and weight of each species was recorded. For large catches, subsamples of 20-30 individuals were taken as a representation of the length distributions of the catch. The standard length, height at the anus (up to the nearest 1 mm), and weight (up to the nearest 0.1 g) were measured for all specimens caught and those in the subsample for abundant species. ### Data management While the PolarFront project publishes all its data on Zenodo, biological diversity datasets are also published in the Global Biodiversity Information Facility (GBIF). The data is prepared using the international Darwin Core (DwC) vocabulary (https://dwc.tdwg.org/) and is distributed as DwC text files that follows GBIF's [data quality requirements](https://www.gbif.org/data-quality-requirements-sampling-events) and [best practices for sampling event datasets](https://ipt.gbif.org/manual/en/ipt/latest/best-practices-sampling-event-data). Prior to publishing all data files are validated using GBIF's data validator (https://www.gbif.org/tools/data-validator). Taxonomy is also validated against the [GBIF API](https://techdocs.gbif.org/en/openapi/v1/species) and [World Register of Marine Species](https://www.marinespecies.org).

This research was conducted aboard the research vessel Helmer Hanssen over a five-day cruise around Svalbard. The fieldwork was a part of a course (AB-202) organized by UNIS (The University Centre in Svalbard), involving 18 students, professors, and the ship's crew. Sampling was carried out at four stations: Isfjorden(IsK), Kongsjorden (KB3), Smeerenburg (SME) and St.Jonsfjorden (STJ). The aim was to investigate benthic communities and environmental conditions across fjords with varying degrees of Atlantic and Arctic influence. At each station, benthic samples were collected using a bottom trawl and Van Veen grab, followed by sieving and taxonomic identification.The dataset provides insight into species composition distribution, and relative abundance in Svalbard fjords during early spring. These data can contribute to longterm monitoring of benthic communities and assessments of climate-related changes in Arctic marine ecosystems.

Relascope sum of Sitka spruce Picea sitchensis in Fusa and Tysnes
Invasive species can be considered a threat to biodiversity, and remote sensing has been proposed as a tool for detection and monitoring of invasive species. In this study, we test the ability to discriminate between two tree species of the same genera, using data from Landsat 8 satellite imagery, aerial images, and airborne laser scanning. Ground observations from forest stands dominated by either Norway spruce (Picea abies) or Sitka spruce (Picea sitchensis) were coupled with variables derived from each of the three sets of remote sensing data. Random forest, support vector machine, and logistic regression classification models were fit to the data, and the classification accuracy tested by performing a cross-validation. Classification accuracies were compared for different combinations of remote sensing data and classification methods. The overall classification accuracy varied from 0.53 to 0.79, with the highest accuracy obtained using logistic regression with a combination of data derived from Landsat imagery and aerial images. The corresponding kappa value was 0.58. The contribution to the classification accuracy from using airborne data in addition to Landsat imagery was not substantial in this study. The classification accuracy varied between models using data from individual Landsat images. The study area is within the Fusa and Tysnes municipalities on the western coast of Norway (60°2′N, 5°46′E, 0–500 m above sea level, Figure 1). The forest is naturally dominated by Scots pine and deciduous species, mainly birch (Betula pubescens). From the 1940s and throughout the second part of the twentieth century, regeneration using non-native tree species—such as Sitka spruce—was common in this region on the west coast of Norway. Note that Norway spruce is also considered non-native in parts of this region. The productive forest area is about 260 km2, and the species composition is approximately 13% spruce, 66% pine, and 20% deciduous trees. Three sets of field observations were utilized in the present study, with observations from a total of 240 individual locations. All locations were situated in a spruce-dominated forest, and the proportions of Sitka spruce and Norway spruce were recorded for all locations. A total of 113 locations were dominated by Sitka spruce, and 127 were dominated by Norway spruce. Two of the sets were initially collected as a part of the data acquisition in other research and forest inventory projects. Field measurements with the main purpose of increasing the number of observations from locations dominated by Sitka spruce was carried out during the summer of 2015. From an initial set of all forest stands in the study area dominated by Sitka spruce, 30 stands were subjectively chosen for measurements. With an initial goal of having the observations evenly spread out in the study area, the selection was ultimately guided by accessibility from, e.g., forest roads. The selection of the 30 stands were carried out prior to visiting the stands in the field, with the exception of a few occasions in which a nearby stand was measured instead due to severe storm felling in the originally chosen stand. Within the selected stands, three locations were subjectively chosen, guided by these criteria: the locations are evenly spread out in the stand and are preferably not close to stand borders. At each of the three locations, the proportions of the basal area of Sitka spruce versus other species were recorded using a relascope.

Specimens from India at the University Museum at the University of Bergen
This dataset includes specimens originating from India in the natural history collections at the University Museum of the the University of Bergen (UiB). Animals: The vertebrate collection contains 18 reptile specimens as well as a few bird eggs and fishes from India. There are no bird skins or mammals in this part of the collection. However, the osteology collection contains 8 craniums and skeletons, in some cases of the same individual. The museum in Bergen contains neither insects nor marine invertebrates from India. Plants and fungi: The vascular plant collection is likely to hold some specimens from India but these are difficult to find as the material is sorted taxonomically and not yet digitised. While the Fennoscandian herbarium had been digitised, there are as yet no plans for the digitisation of the general herbarium. Some 30% of the bryophyte herbarium has been digitised, including 41 specimens from India (10 of these where previously visible in the GBIF portal). Once the complete bryophyte herbarium is digitised (80 0000 specimens) there may be an estimated number of 150 mosses from India. Lichens and fungi have all been digitised and include 39 lichen specimens from India and no fungi. 34 lichen specimens where previously visible in the GBIF portal.

Downward vertical flux of protist cells and biomass in the northern Barents Sea during August 2018, Nansen Legacy cruise 2018707 J/C 1-2
Samples for protist cell and biomass flux were collected with short-term drifting sediment traps between 75° and 85°N in the northern Barents Sea with R/V Kronprins Haakon in August 2018 as part of the Nansen Legacy project (cruise 2018707, JC 1-2). High-density bottom water was collected at the station and filtered (Whatman GF/F 0.7µm), and then filled into the trap cylinders (KC Denmark, aspect ratio >6) prior to their deployment. Afterwards, the sediment traps were deployed with 2 or 4 cylinders at each depth (30, 40, 60, 90, 120, 200m) for a duration between 22 to 25 hours. Depending on the sea ice conditions, the sediment traps were deployed in open water, anchored to a sea ice floe or within an ice lead. Upon retrieval, the content of the cylinders from each depth was pooled and stored at 4°C in dark until further analyses. For protist examination, a subsample of 100ml was transferred to a brown glass bottle and fixed with a mixture of glutaraldehyde-lugol. Protists were identified to the lowest possible taxonomic level in accordance with the World Register of Marine Species (WoRMS) and counted under an inverted light microscope (Nikon Eclipse TE-300 and Ti-S) using the Uthermöhl method (Edler & Elbrächter, 2010; Utermöhl, 1958). Protist carbon biomass flux was calculated from abundances using established geometric relationships for biovolume conversion (Hillebrand et al., 1999) and biovolume-to-carbon conversion factors (Menden-Deuer & Lessard, 2000). Note: column footprintWKT = ("deployment_latitude deployment_longitude" (always available) , "recovery_latitude recovery_longitude (if available, otherwise NA)"

This study sought to determine the current status of the Red-tailed Monkey and its habitats in eleven peri-urban forest fragments. A tree enumeration was conducted along the same transect used for censuring monkeys. These are the trees that provide both the food resources and a medium for travel and rest for the arboreal primates. Large trees (>100cm dbh) were found missing in most of the fragments and where present, these were few. Tree basal area and composition did not show a significant relationship with red-tailed monkeys’ group size. Belt transect method was employed for the enumeration exercise. A transect was established across each forest. A 2.5m strip on either side of the transect was established within which all trees with diameter greater than or equal to 10cm at breast height were measured using a diameter tape and recorded.

Bumble bees collected in a large-scale field experiment in power line clearings, southeast Norway
Anthropogenic landscape elements, such as power line clearings, can be managed to provide important habitats for wild bees. However, the effects of habitat improvement schemes in power line clearings on components of diversity are poorly studied. We conducted a large‐scale experiment to test the effects of different management practices on bumblebees in power line clearings. Bumblebees were sampled using flight-interception traps at 19 sites during a large-scale field experiment within the main power-line grid in Southeast Norway. The 19 sites were located between latitudes 59.33°–61.12°N and longitudes 08.95°–11.36°E (WGS84) at 48–536 masl. The sites were mainly located in forested areas, consisting of the main tree species, Norway spruce (Picea abies (L.) H.Karst.), Scots pine (Pinus sylvestris L.) and birch (Betula spp.). Each site had been subjected to the same management regime with cutting of all woody vegetation every 5-10 years, without chemicals used, and had a stretch of at least 200 meters with substantial regrowth of trees before experiments were performed. The bee specimens were collected below power-lines in three 30 m x 60 m plots [corridor width], at least 20 m apart, where the vegetation was either; (1) cut: woody vegetation was cut and left to decay in the plot, (2) cut-remove: woody vegetation was cut and removed, (3) Vegetation was uncut. Within each treatment plot, three flight-interception traps (window traps) were set out immediately after snowmelt in 2013, 2014 and 2015. The flight interception traps consisted of two transparent Plexiglas screens (370 mm × 210 mm) that formed a cross, with a funnel and collecting bottle attached to it. The collecting bottle was filled with a 50:50 mixture of green propylene glycol and water, in addition to a drop of detergent. Every month we collected the bottles and immediately replaced them with new ones. The traps were emptied 4-5 times throughout the entire flowering season, from snowmelt in May to the end of the foraging activity‐season in September. This procedure ensured a continuous, standardized sampling among all sites. All bees were sorted and identified to species by Mari Steinert, Helene Totland Müller and Markus A.K. Sydenham. The cuckoo bumblebees and some specimens of each species are pinned. All of the material is stored at the Norwegian university of Lifesciences (NMBU).

Vascular plants from a study of primary producer traits across an altitudinal gradient in alpine Finse
One of the major challenges for contemporary ecologists is to understand how ecological communities respond to environmental changes. Although classifying species to their taxonomy is useful, it has major limitations when it comes to answering ecological questions. A more functional approach, based on a species set of traits that define its performance within an ecosystem, provides much more insight. Many plant ecologists have now applied such trait-based approaches, but these studies are often limited to vascular plants and do not include other important primary producer groups such as lichens and bryophytes. However, there may be clear differences in what drives changes in community level traits across environmental gradients between producer groups: in vascular plants changes in species community are often most important and intraspecific variation is often also significant, whereas recent studies suggest that in lichens intraspecific variation alone drives changes in community level traits. In this study, we will disentangle the relative importance of species turnover versus intraspecific variation as drivers of community-level traits in different primary producer groups simultaneously across the same environmental gradient in Finse, Southern Norway. The % cover was estimated visually in 50x50cm subplots with a wire frame marking out 10x10cm squares. All species covering less than 1% was marked as cover = 0.5 in the data.

Nordic plant uses from Gunnerus and Høeg
The dataset has been created as part of the research activities for the Nordic People and Plants project. The project aims to rediscover Nordic plant traditions. This dataset represents plant use data collected from two key Norwegian historical sources of plant knowledge: Flora Norvegica (J.E. Gunnerus, 1766-1776): A major Enlightenment natural history work in Norway. Published in Trondheim in 1766, this was the first explicitly Norwegian flora. It gives an insight in the Norwegian daily life in that period through descriptions of plant uses. Planter og Tradisjon: Floraen i levende tale og tradisjon i Norge 1925-1973 (O.A. Høeg, 1974): Norway's most important ethnobotanical compilation. Høeg corresponded with informants all over Norway to document what was left of oral traditions related to plants. Most of the data is presented as he received from the informants.

Phytoplankton community composition in the water column of East Greenland fjords, August 2022
The community composition of suspended phytoplankton was investigated at 7 stations along the East Greenland coast as part of the EU project ECOTIP. Water was sampled in Dove Bay (1 station: 5, 40, 50 m), Kong Oscar fjord (2 stations: 5, 42, 50 m and 5, 43, 50 m), Arden Caple fjord (3 stations: 5, 40, 50 m; 5, 40, 50 m; 5, 20, 50 m) and outside Scoresby Sound on the continental shelf (1 station: 5, 40, 50 m). While 5 m and 50 m were used as standard depths, the intermediate depth was chosen depending on the fluorescence sub-surface maximum. At each sampling depth, the water was collected with a 10 L Niskin bottle attached to a sampling rosette. A subsample of 100 mL from the Niskin bottle was preserved with 1 mL acidic Lugol’s solution for later microscopic analysis. From this field work, there are also other data available: 1) cruise track with a station list (https://doi.org/10.1594/PANGAEA.953084, https://doi.org/10.1594/PANGAEA.953083), 2) underway measurements (https://doi.org/10.1594/PANGAEA.959027), 3) concentration of suspended chlorophyll a, phaeophytin, particulate organic carbon (POC), and particulate organic nitrogen (PON) (https://doi.org/10.11582/2024.00038), 4) downward flux of chlorophyll a, phaeophytin, particulate organic carbon (POC), particulate organic nitrogen (PON), and the atomic ratio of POC:PON (https://doi.org/10.11582/2024.00040, and 5) community composition of sinking protist cells (https://doi.org/10.15468/ds6q26).

Equinor bird monitoring at Hywind Tampen
Three CCTV cameras are installed in the Hywind Tampen floating offshore wind farm in Norway for the purpose of health, safety and environmental (HSE) monitoring. However, the data collected by these cameras also offer the potential to document presence, abundance and behaviour of birds within the offshore wind farm. To investigate this, Equinor partnered with Spoor to rapidly scale this approach, and contribute to filling key gaps in our understanding of bird movements in and around offshore wind farms. The birds in the dataset were identified by applying Spoor's AI bird-monitoring technology to Hywind Tampen video material provided by Equinor. For further details on the methodology and results, please see the associated report: https://cdn.equinor.com/files/h61q9gi9/global/c4a3e3487044b0280804db9fc9cb4e1d890f374f.pdf?spoor-review-ai-avian-monitoring-cctv-cameras-floating-wind-turbines-equinor.pdf

A century of treeline and forest line data for Betula pubescens subsp. czerepanovii across high elevations in Norway
The dataset is structured in Darwin Core (DwC) format, utilizing the Event Core and Occurrence extension to organize and standardize the data. Each event represents a collection of treeline or forest line observations made at a specific location, encapsulating both historical and modern records. Historical observations, which typically include only altitude and the name of the location, are grouped with newer registrations that feature precise GPS coordinates. This approach ensures that all observations associated with a given site are grouped logically, facilitating temporal comparisons and allowing for comprehensive analysis of changes over time, even when precise spatial data is unavailable for older records. is a placeholder

Springtales from lichen communities at Kollåsen in Norway
The data collections were conducted as part of a larger project called FuncFinse. We aimed to study if and how the (functional) diversity of lichen communities determines the species diversity and community composition of micro-arthropods (Collembola). We created experimental patches with mixtures of one, two, three, or four different lichen species and placed these in lichen mats in semi-open pine forest (Pinus sylvestris) in Kollåsen, Ski, Norway. The soil micro-arthropods were harvested from the lichen patches after one summer season of incubation.

Mapping of vulnerable marine species and habitats, Midfjorden in Vestnes
On behalf of SalMar Farming AS has Aqua Kompetanse AS conducted a survey of vulnerable species and habitats in shallow waters (0–50 m) and deep waters (>50 m). The purpose of the survey is to identify the presence and observed density of vulnerable species that may form habitats listed on the Norwegian Red List for Ecosystems and Habitat Types (Artsdatabanken, 2018), on OSPAR’s list of threatened and/or declining habitats (OSPAR 2008-06, revised in 2021), and among the proposed management-relevant habitat types for fisheries and aquaculture (Institute of Marine Research Report, 2024-16). At depths greater than 50 meters, the focus is mainly on corals, sponges, and sea pens. However, other red-listed and/or vulnerable species that live in close interaction with the three-dimensional habitats formed by the aforementioned groups will also be described when relevant. At depths shallower than 50 meters, the survey includes kelp forests, soft-bottom shoreline areas, coarse substrate bottoms, marine seagrass beds, exposed blue mussel beds, oysters, scallop populations, corals, sponges, sea pens, and any other red-listed shallow-water species. The investigation is based on the Institute of Marine Research’s proposed methodology for surveying vulnerable species and habitats in deep water (>50 meters depth) in connection with applications for marine aquaculture (Kutti and Husa 2021).

Epimegabenthos based on seafloor georeferenced mosaics of the Lofoten-Vesterålen canyon seeps
This dataset consists of all the epimegabenthic fauna marked and enumerated from five seafloor georeferenced image mosaics from two canyons with methane seep conditions on the continental slope off the Lofoten-Vesterålen archipelago of northern Norway. Two of the mosaics are from the inner part of the seep from the southern of the two canyons, one mosaic is from the inner part of the seep from the northern canyon and three mosaics are from the edges of the seep from the northern canyon. Videos of the seafloor were obtained with the the remotely operated vehicle (ROV) Ægir from the research vessel Kronprins Haakon, maintaining an altitude of between 1 and 1.5 m. Images were extracted every 3 seconds via the free software ffmpeg and using the images and their associated navigation data, georeferenced mosaics were generated with Agisoft's Metashape software. The mosaics cover areas betweeen 133 m2 and 400 m2 . The mosaics were inputted into Arc Desktop and using the Editor tool, all fauna were identified, marked and enumerated. All individuals were marked to obtain numbers for each taxon. Colonial or encrusting animals were outlined to obtain areal coverage. Identifications were made to the lowest possible level which was species in many cases, but only phylum in some cases. The faunal data from the two mosaics of inner parts of the seep in the southern canyon were used in the publication by Sen et al. 2019 'Atypical biological features of a new cold seep site on the Lofoten-Vesterålen continental margin (northern Norway) in Scientific Reports. The other mosaics are used in a publication by Sen et al. on communities at the edges of seeps.

Monitoring data of natural and man-made semi-natural meadows in and around Oslo, Norway 2018-2021
Survey data from monitoring a selection of meadow sites in the municipalities Oslo, Bærum and Lillestrøm in Norway. Meadows are both semi-natural and created by humans as part of ecological improvement measures. The aim of the monitoring is to compare biodiversity between the various types of semi-natural and man-made meadows located primarly in the urban environment of Oslo, and to evaluate restoration success over time. The data consists of human observation of primarly vascular plants, but some instances of mosses and lichens are recorded as well. Data was first collected in 2018, with a follow up in 2019. In 2019 a larger number of meadows was included. One of the sites (Mustad at Lysaker, Oslo) was surveyed in 2021, and monitoring of this site is planned bi-anually from 2021 to 2029.

Specimens of marine invertebrates collected in coastal areas by environmental monitoring (1973–2000), housed at the University Museum of Bergen
Specimens collected and reported by the company SAM-marin (now STIM) from various environmental monitoring surveys in coastal areas and fjords from Agder to Nordland County. The material was collected in the years 1973-2000 and later deposited at the University Museum of Bergen (UMB) as documentation of species records and as a resource for research in biosystematics. Datasets from environmental monitoring are important documentation of species occurrences in time and space, and such datasets are of particular interest when specimens have been deposited in Museum collections as this will allow for future revisions and updates of species occurrence data. The material is stored as bulk samples of main taxon (e.g. polychaeta) from a given locality, typically a grab sample, and represents an important collection, although not with the same status as the traditional taxonomic Museum collection.

Dette datasettet inkluderer arter som er knyttet til registrering av DN Håndbok 13 for naturtyper. Vi baserer oss på egenskapen 'artsmangfold' i datesettet DN-Håndbok 13. Vi bruker så Nortaxa for å sjekke artsfunn, dette gjøres i flere steg. Men for alle steg så sjekker vi bare artsnivået, og arter som ansett til å eksistere i Norge. Alle artsnavn blir prefikset og suffikset med et mellomrom, slik at vi unngår feiltreff slik som 'raudmus' og 'raudmuslingmose'. 'artsmangfold'-egenskapen får også erstattet alle komma, punktum og paranteser med et mellomrom for å bedre sannsynligheten for treff ved oppramsing av artsnavn, slik som "steinskvett, fjellpryd og stjernesildre". Treffet må være slik at ordet starter med artsnavnet; slik at 'rødstjert' ikke blir forvekslet med 'svartrødstjert'. Artsnavnene ble sjekket trinnvis: 1) Sjekk opp mot arter med populærnavn bokmål.a) Vi utelukket så kombinasjoner av arter og HB13-forekomster med funn.b) Sjekket gjenværende for treff av nynorsk populærnavn og latinsk artsnavn (slekt + artsepitet) 2) For alle arter uten populærnavn så sjekket vi treff for latinsk artsnavn (slekt + artsepitet). Dette inkluderte også synonyme artsnavn. Avslutningsvis sjekket vi for alternative norske navn, slik som natt og dag for stemorsblomst. En del artsfunn fra disse kartleggingene er lagt inn separat i Artskart av kartleggerne. For å unngå dobbeltregistrering foretar vi derfor en kvalitetskontroll opp mot GBIF. Vi spør da først om et gitt forekomst +/- 14 dager av registreringsdato har noen artsfunn, hvis den har artsfunn så sjekker vi hvilke arter dette er. 5393 HB13-forekomster hadde ingen treff i GBIF for den gitte datoen, 3601 hadde treff for rundt registreringsdatoen. Konkrete observatører og underlagsrapporter kunne ikke automatisk anerkjennes slik at vi viser til referansene og dertil faktaark for mer informasjon om dette.

Specimens from India at the Natural History Museum at the University of Oslo (NHM-UiO)
This dataset includes specimens originating from India in the collections at the Natural History Museum at the University of Oslo (NHM-UiO). Animals: The mammal collection includes 108 specimens (mounted animals, skulls or skins, sometimes from the same individuals) from ‘India’. Insofar these are dated at all, they originate from the 19th century. No further collecting information is preserved. These data are already available from the GBIF portal (and not included in this dataset). Oslo has 1027 bird specimens from India, both skins and mounted and demounted specimens. These are either not dated or originate from the 19th century or the first half of the 20th century. Locality is sometimes recorded at the region or district level, with relatively many specimens from Darjeeling. More detailed collecting data are missing. Most have been collected by Englishmen, some of whom have had an important role in Indian ornithology. These skins may therefore be of particular historical value. Notable are 295 skins labeled as being collected by ‘Blyth’. This name most likely refers to the English zoologist Edward Blyth (1810 –1873), who was one of the founders of zoology in India (cf. Wikipedia lemma Edward Blyth). Another known name is Henry Seebohm (1832-1895), to whom twelve skins are attributed (misspelled in one case as Subohm). The bird data are not yet published in GBIF. The fish collection contains 34 databased specimens. The Staphylinidae beetle collection includes 508 specimens from India which are not yet identified to species level. The Hymenoptera collection includes 130 pinned specimens originating from the collection of Charles Thomas Bingham (1848-1908). These have been collected in Sikkim. In addition there are 7 Hymenoptera and 1 Orthoptera originating from the Deinboll collection, all labelled Trankebar. Some of these may represent types of taxa described by J.C. Fabricius (1745-1808). These collections are not yet digitised. There are virtually no Lepidoptera or Diptera from India in Oslo. Finally, the museum holds circa 10 crustacean specimens and 3 molluscs. Plants: There is a small digitised collection of 89 vascular plants from Himachal Pradesh and Maharashtra provinces. These were deposited by the Indian student B. Natarajan who studied in Oslo in the 1990s. In addition, the older vascular plant type collection in Oslo has been digitised. This includes 12 older type specimens from India. Most of the herbarium has not been digitised, however. It may contain between 5 000 and 10 000 specimens from India. These are currently difficult to locate as the herbarium is organised in taxonomic rather than geographic units. The museum intends to digitise the herbarium at a level that would enable the retrieval of taxa per continent or even per country. This enterprise is still in the planning phase, however. Likewise the bryophyte and algae collections might contain material from India, but this can only be retrieved after digitisation. Some of these records are published to GBIF as a separate dataset. Oslo probably holds no Indian fungi. The digitisation of the Oslo lichen herbarium is ongoing. Currently 34 specimens from India are visible in the GBIF portal (and not included i this dataset). This number may increase to circa 100 once the entire lichen herbarium is digitised. Most of these have been collected after 1950 and have rather complete collecting data. The botanical garden in Oslo has 6 living plants originating from India.

Presence-absence of plant habitat specialists in 15 patches
We present three years of presence-absence data of 49 vascular plant species in 15 patches of dry, calcareous grassland habitat. The species are considered to be habitat specialists, and thus unlikely to occur in between the patches. The data set combines three years of surveys, the last of which are re-surveys of a subset described in previous publications (Bakkestuen et al., 2014; Evju et al., 2015, 2016; Evju & Sverdrup-Thygeson, 2016; Wollan et al., 2011). Absences can be inferred for the 49 species included.

The Norwegian Red List of Species 2015 has been compiled by the Norwegian Biodiversity Information Centre in cooperation with 24 committees of experts with a total of 90 members. The Norwegian Red List of Species includes species that are assessed as being at risk of extinction within Norway. Each species is placed in one of a number of categories, which are ranked according to the level of risk that species will die out if conditions remain unchanged. Red list assessments are only made for species that are or have been established as reproducing species in Norway. Alien species, in other words species that have been spread to Norway since 1800 by human activity, are not assessed. Species are assessed against a set of criteria developed by the International Union for Conservation of Nature (IUCN). The criteria and guidelines for using them ensure that assessments are standardised, verifiable and objective. The categories reflect the level of risk that a species will die out if conditions remain unchanged. Species in the categories Critically Endangered (CR), Endangered (EN) and Vulnerable (VU) are described as threatened species. The assessments for most species groups apply to mainland Norway and adjacent Norwegian sea areas. In all, 21 402 species and 278 subspecies of vascular plants have been assessed for the 2015 edition of the Red List.

Photographs of higher plants, mosses, fungi, lichens, and algae
This archive encompasses photographs of vascular plants, mosses, algae, lichens, fungi, and some other organisms previously regarded as “plants”. All pictures are photographed by Klaus Høiland in Norway or abroad. All people are free to use these photographs if the photographer is mentioned, and the picture is not intended for commercial purposes. For personal security all pictures of people, e.g. as measuring standard by some plants, are blurred. The vascular plants are sorted by families following the systematics presented by Angiosperm Phylogeny Website, version 14., Missouri Botanical Garden, (http://www.mobot.org/MOBOT/research/APweb/). The other organisms are presented by orders (lichen and fungi) or phyla (mosses and other organisms, except a few prokaryotes that are grouped together). Inside these categories the names normally follow the alphabet of the scientific names, except in cases were these names newly have been changed for taxonomic or nomenclatorial reasons. The presentation of the pictures is given in the following notation: Scientific name of the species (Taxonomic category, either family, order or phylum) NORWEGIAN NAME, state in Norway and sometimes special features for the actual photography (locality where the picture has been photographed) For instance: Hepatica nobilis (Ranunculaceae) BLÅVEIS, wild, growing place (N, Oslo, Bygdøy) Dracaena draco (Asparagaceae) DRAGEBLODSTRE, exotic (Spain, Tenerife, Icod) Amanita muscaria (Agaricales) RØD FLUESOPP, wild (N, Halden, Frediksten) Buxbaumia viridis (Bryophyta) GRØNNSKO, wild, red list (N, Oslo, Lillomarka, Styggedalen) The scientific names follow the Norwegian Biodiversity Information Centre (Artsdatabanken). Exotic organisms follow names found in Store Norske Leksikon or other reliable internet sources. The Norwegian names also follow those given by the Norwegian Biodiversity Information Centre (Artsdatabanken). Norwegian names for exotic plants are found in Store Norske Leksikon or other reliable internet sources. The state in Norway has following representation: wild: The organisms are natural (spontaneous) in Norway. For vascular plants this notation also includes weeds that have been in Norway before 1800, together with other obviously introduced plants, but which have been a part of our flora before 1800 (following the view by Norwegian Biodiversity Information Centre (Artsdatabanken)). Organisms appearing after 1800, but arrived Norway by natural ways, e.g. sea currents and birds, are similarly regarded as wild. introduced: This means organisms introduced by man, either involuntarily (as several weeds following import of goods or by vehicles or ships) or by purpose (as garden plants, alien forest trees, vegetables, cereals). Included are also parasites introduced by imported vectors (plants or animals). They must have been registered as established in the nature of Norway after 1800, either by specimens in museums or mentioned in literature. For some alien forest trees, where we know the history of introduction, the age is sometimes set before 1800. wild and introduced: This state means that the organisms originally were wild, but has been re-introduced by man. This notation is most actual where the wild occurrences has been extinct (or nearly so), but has be re-introduced afterwards. wild, ephemeral: This means organisms considered as wild, but unstable, appearing a short time on its localities, often disappearing and sometimes re-establishing. “Hello goodbye”-organisms. wild, vanished: Originally wild organisms that have been extinct for a long time. They will have the category “regionally extinct” RE on the red list. red list: The organisms are included in the latest version of the red list, Rødlista 2015, provided by the Norwegian Biodiversity Information Centre (Artsdatabanken) (encompassing the categories CR, EN, VU, NT, and DD, but not RE). problem: This indicates an introduced organism that is a problem, usually an invasive species with high ecological impact. With few exceptions only species with very high or high risk in the latest version of Fremmedartslista (2018) provided by the Norwegian Biodiversity Information Centre (Artsdatabanken) are mentioned as problem. exotic: Organisms not occurring in Norwegian nature. They are either photographed abroad or in Norway as cultivated specimens. Such cultivated specimens cannot be considered as introduced according to the context used here, since they are not spreading into Norwegian nature. Sometimes special features of the picture is mentioned, e.g. if it shows the growing place, special characteristics as fruits, seeds, female or male structures, accompanying animals and so forth. In parenthesis the place where the photograph is taken is mentioned: land (N = Norway, S = Sweden, other lands unabbreviated), community/landscape, locality etc. For threatened and charismatic species it is stated “locality not given” for conservation reasons.

Macrofauna associated with submarine groundwater discharge sites and a cold seep in Svalbard fjords
This dataset contains macrobenthic occurrence data collected in March 2023 from onboard the research vessel Kronprins Haakon as part of the ArcticSGD project. The study investigated the influence of submarine groundwater discharge (SGD) on benthic macrofaunal communities in Svalbard fjords, Arctic Norway. Sampling took place at three SGD sites: Tempelfjorden inner basin (T SGD; 78.4 m water depth), Murdoch Hole (M SGD; 39.5 m water depth), and Hornsund (H SGD; 117 m water depth), and one cold seep site on the Hornsundbanken shelf (HB; 126 m water depth). At the Hornsundbanken seep, samples were taken from two microhabitats: microbial mats (HB mats) and regular seep sediment (HB reg).At the two Tempelfjorden sites, two replicate sediment cores (9 cm diameter) were collected using a GEMAX corer. At Hornsund and Hornsundbanken, three replicate push cores (8.5 cm diameter) were taken using the remotely operated vehicle (ROV) Ægir 6000. Sediment cores were sieved over a 0.5 mm mesh and immediately preserved in 4% buffered formaldehyde, then transferred to 70% ethanol in the laboratory. Macrofauna were sorted under a Leica MZ16 A stereomicroscope and identified to the lowest taxonomic level, typically species level. The number of individuals for each taxon was counted and abundance standardized to m². Wet weight was determined after blotting on a scale resolving to 0.001 g, and biomass was also standardized to m².

Priority effects of early successional insects influence late successional fungi in dead wood
Community assembly is an integral process in all ecosystems, producing patterns of species distributions, biodiversity, and ecosystem functioning. Environmental filters and colonization history govern the assembly process, but their relative importance varies depending on the study system. Dead wood decomposition is a slow process, allowing decomposer communities to develop within a slowly changing substrate for decades. Despite this, there are few long-term studies of priority effects from colonization history in this ecosystem. In this study, we investigate the importance of insects in early succession of dead wood on the fungal community present one decade later. Sixty aspen trees were killed in two study landscapes, each tree producing one aspen high stump and log. Insects were sampled with flight interception traps during the first 4 years after tree death, and fungal fruiting bodies were registered in year twelve. We found positive priority effects of two fungivorous beetles, the sap beetle Glischrochilus quadripunctatus and the round fungus beetle Agathidium nigripenne, on the Artist’s bracket (Ganoderma applanatum) and a positive priority effect of wood-boring beetles on the ascomycete Yellow fairy cup (Bisporella citrina). The Aspen bracket (Phellinus tremulae) did not respond to insects in early succession of the dead wood. Our results suggest that early successional insects can have significant, long-lasting effects on the late successional fungal community in dead wood. Also, the effect can be specific, with one fungus species depending on one or a few fungivorous beetle species. This has implications for decomposition and biodiversity in dead wood, as loss of early colonizing beetles may also affect the successional pathways they seem to initiate.

Mapping of vulnerable marine species and habitats, Frohavet-Flesafjorden, in Åfjord Municipality
On behalf of SalMar Farming AS, Aqua Kompetanse AS has conducted a survey of vulnerable species and habitats in shallow waters (0–50 m) and deep waters (>50 m). The purpose of the survey is to identify the presence and observed density of vulnerable species that may form habitats listed on the Norwegian Red List for Ecosystems and Habitat Types (Artsdatabanken, 2018), on OSPAR’s list of threatened and/or declining habitats (OSPAR 2008-06, revised in 2021), and among the proposed management-relevant habitat types for fisheries and aquaculture (Institute of Marine Research Report, 2024-16). At depths greater than 50 meters, the focus is mainly on corals, sponges, and sea pens. However, other red-listed and/or vulnerable species that live in close interaction with the three-dimensional habitats formed by the aforementioned groups will also be described when relevant. At depths shallower than 50 meters, the survey includes kelp forests, soft-bottom shoreline areas, coarse substrate bottoms, marine seagrass beds, exposed blue mussel beds, oysters, scallop populations, corals, sponges, sea pens, and any other red-listed shallow-water species. The investigation is based on the Institute of Marine Research’s proposed methodology for surveying vulnerable species and habitats in deep water (>50 meters depth) in connection with applications for marine aquaculture (Kutti and Husa 2021).

Bryophytes from a study of primary producer traits across an altitudinal gradient in alpine Finse
One of the major challenges for contemporary ecologists is to understand how ecological communities respond to environmental changes. Although classifying species to their taxonomy is useful, it has major limitations when it comes to answering ecological questions. A more functional approach, based on a species set of traits that define its performance within an ecosystem, provides much more insight. Many plant ecologists have now applied such trait-based approaches, but these studies are often limited to vascular plants and do not include other important primary producer groups such as lichens and bryophytes. However, there may be clear differences in what drives changes in community level traits across environmental gradients between producer groups in vascular plants changes in species community are often most important and intraspecific variation is often also significant, whereas recent studies suggest that in lichens intraspecific variation alone drives changes in community level traits. In this study, we will disentangle the relative importance of species turnover versus intraspecific variation as drivers of community-level traits in different primary producer groups simultaneously across the same elevational gradient in Finse, Southern Norway. The % cover was estimated visually in 50x50cm subplots with a wire frame marking out 10x10cm squares. In each of the five sites (elevations), there were five plots. The cover estimates presented in this dataset are on the plot level (averaged over the subplots).

Epimegabenthos based on seafloor georeferenced mosaics of the Hornsundbanken methane seep area
This dataset consists of all the epimegabenthic fauna marked and enumerated from two seafloor georeferenced image mosaics from the shelf off Svalbard's Hornsund fjord (Hornsundbanken). Videos of the seafloor were obtained with the the remotely operated vehicle (ROV) Ægir from the research vessel Kronprins Haakon, maintaining an altitude of between 1 and 1.5 m. Images were extracted every 3 seconds via the free software ffmpeg and using the images and their associated navigation data, georeferenced mosaics were generated with Agisoft's Metashape software. The two mosaics cover areas of 282 m2 and 164 m2 (446 m2 combined). The mosaics were inputted into Arc Desktop and using the Editor tool, all fauna were identified, marked and enumerated. All individuals were marked to obtain numbers for each taxon. Colonial or encrusting animals were outlined to obtain areal coverage. Identifications were made to the lowest possible level which was species in many cases, but only phylum in some cases. The faunal data from these mosaics were used in the publication by Sen et al. Fauna of shallow water Arctic seep not driven by water masses currently under review.

Downward flux of phytoplankton cells on the West Greenland continental shelf, July 2021
Short-term sediment traps were deployed at 3 stations on the West Greenland continental shelf in the Davis Strait. The deployments lasted for 18.7-24.4 hours and 100 mL subsamples were collected from the sediment trap cylinders (KC Denmark style with 72 mm inner diameter) deployed at the sampling depths 20, 30, 50, 90, and 120 m. The phytoplankton samples were preserved with 2 mL acidic Lugol solution, stored cool (+4 C) and in darkness, until the microscopical analysis. Since the sediment trap cylinders were not prefilled with filtered sea water, a minor overestimation of the downward flux cannot be excluded. From this field campaign, also the cruise report is publicly available on Zenodo (https://zenodo.org/doi/10.5281/zenodo.5913276). In addition, the following data sets are available: 1) the concentration of suspended chlorophyll a and phaeophytin (>0.7 and >10 micrometre) as well as particulate organic carbon (POC) and nitrogen (PON) in the water column (https://doi.org/10.11582/2024.00039), 2) the downward flux of Chl a, Phaeo, POC, PON at three stations (https://doi.org/10.11582/2024.00041), and 3) the protist composition in the water column (https://doi.org/10.15468/sfxd3c).

The effect of Macrotermes on distribution and abundance of rodents in Lake Mburo National Park, Uganda
Small rodents trapped in African savannahs, to compare the population of rodents on and off termitaria in a savanna area. In addition, an experiment to assess the effect of herbivore exclusion on the population of rodents on and off termitaria in a savanna area. Large herbivores and termites are important functional groups in African savannahs. Both groups affect small mammals, which are also important determinants for savannah structure and function. Because vegetation on Macrotermes mounds are preferentially grazed by large herbivores, and mounds represent resource-rich distinct habitat patches for small mammals in relatively resource-poor savannahs, termite mounds are ideal sites for studies of how grazing by large mammals and productivity affect communities of small mammals. We conducted an experiment in Lake Mburo National Park, Uganda, with four treatments: large vegetated Macrotermes mounds (with and without large herbivores) and adjacent savannah areas (with and without large herbivores). We replicated the treatment blocks nine times and trapped small mammals regularly over a period of almost 2 years. Small mammal species assemblages differed considerably between mounds and savannah areas. Grazing had a substantial effect on small mammal species assemblages in the resource-poor savannah, but not in the relatively resource-rich termitaria. Small mammal species abundance, biomass, and richness were higher on termite mounds than adjacent savannah areas. Excluding large herbivores caused a major increase in species abundance, biomass, and richness both on savannah and termitaria. Herbaceous plant species evenness was an important determinant of the small mammal community. Small mammal biomass increased with high plant dominance, indicating that a few dominant plant species are important for biomass production of small mammals. Small mammal diversity was not related to any of the treatments, but increased with plant species evenness as well as richness. Fencing increased species dominance in the small mammal community on both savannah and termitaria, probably because competitive patterns shift from inter-guild (that is, between large and small mammals) to intra-guild (that is, between small mammals) when large mammals are excluded. The study highlights the complex interactions among large herbivores, termites, herbaceous plants, and small mammals in African savannahs. When studying the structure and function of small mammal communities it is therefore important to consider several coexisting functional groups.

Radiolaria specimens from Korsfjorden Nov 1969 - May 1971
This dataset is the result of a radiolarian sampling program from Korsfjorden (60.19110 N,5.23136 E), on the west coast of Norway near Bergen, that took place from November 1969 and ended in May 1971. At the sampling location the fjord depth is 670 m. The water column was divided into 100 m depth zones (100-0 m, 200-100 m, ….600-500 m, and 650-600 m) except for the deepest zone where the sampling started ca. 20 m above the mud line to avoid contamination of the net. At each sampling date all depth zones were sampled. A plankton net with 63 µm mesh opening was used. This dataset also includes the phaeodarians found in this dataset. A total of 72 species was observed. A discussion of this dataset can be found in: Bjørklund, K.R., 1974. The seasonal occurrence and depth zonation of radiolarians in Korsfjorden, Western Norway. Sarsia, 56: 13-42. An archive of this dataset, consisting of a user friendly spreadsheet and an original spreadsheet is available for download here: https://doi.org/10.5281/zenodo.3248925

Environmental Monitoring database (MOD) DNV
DNV is a risk and classification company with roots dating back to the founding of Det Norske Veritas (DNV) in 1864. DNV operates in the oil, gas, and renewable energy sectors. The data produced by DNV is stored in their own Environmental Monitoring database (MOD). It comprises approximately 2.8 million species occurrence records, as well as chemical and geology records. This information comes from grab sampling conducted in areas around oil drilling stations. GBIF Norway is working with DNV to publish the species abundance data in the MOD database. The grab sampling process is done on a yearly basis around the months of May and June, but not all stations are sampled each year. In general sampling is done around each station every third year, and in some areas samples have been repeated since the 1990s.

UNIS AB202 2026 Phytoplankton data from Ny-Ålesund
This dataset is a species list of different phytoplankton observed during the UNIS field course for AB202 in Kongsfjorden, near Ny-Ålesund. Four different locations were sampled over four days. The first site sampled was performed from the west side of the Ny-Ålesund pier, labelled Ny-Ålesund Pier West. The second site sampled was performed by boat, labelled ST1 (station 1), an area not previously surveyed. These first two sites were sampled the same day by the same group. The third site sampled was KB3 (Kongsfjorden Biology), a research site with annual sampling. The fourth and fifth samples had to be performed from the pier due to boat trouble. They were both performed at the east side of the pier, labelled Ny-Ålesund Pier East. All samples were analysed and identified to either species or genus. The individual count of each species was not recorded, due to very low abundancies of phytoplankton. Each group recorded which species they observed, and the dataset is therefore sorted into locations and which species were present.

Survey of freshwater pearl mussel in Lysakerelva, Norway
In March 2023, freshwater pearl mussels was re-located in the Lysaker river. The relocation was carried out as a precautionary measure because the discharge of injection compounds from the tunnel work at Fornebubanen can cause damage/mortality to occurrences of mussel in the area of influence. Fornebubanen is obliged to monitor the mussel population in the river and report annually to the State Administrator on the condition. On behalf of Fornebubanen, NaturRestaurering AS has carried out a survey in June 2023.

Plants from India in the vascular plant herbarium, Natural History Museum at the University of Oslo (NHM-UiO)
This dataset includes specimens originating from India in the vascular plant herbarium, the Natural History Museum at the University of Oslo (NHM-UiO). Introduction: As the country of India has banned the export of plant specimens, specimens collected in India prior to the ban are of high value for the research community. This report is from a survey of the herbarium sheets in the vascular plant herbarium of Oslo which ended in an inventory of plants from India present in the herbarium. Due to ongoing mass digitization of the vascular plant herbarium in Oslo, the angiosperms were only surveyed up to and including the family of Cyperaceae. The specimens were primarily collected in the mid or late 19.th century. Whereas most are personal collections and some are from “flora exsiccata”, which were herbarium sheets sold by sellers that did not necessarily collect the specimens themselves. The collectors: One of the earliest collectors which has donated material to Oslo was Nathaniel Wallich (1786-1854). Unfortunately he did not specify where in India or when the collection was made. But it is known that he arrived in India in 1807, and that he retired aroud 1846. It is also known that he spent most of the time in or around Calcutta, but he also made several expeditions to what is now known as neighboring countries of India. Wallich described many new species on his journey, and some of the specimens might therefor be type specimens. The most famous, and important of the collectors may be Joseph Dalton Hooker(1817-1911), who collected along with Thomas Thomson (1817-1878), mainly in the Khasia area. They also split up and went for individual surveys where J.D. Hooker went to Sikkim, and T. Thomson went to the western Himalaya and Punjab. J.D. Hooker is known to have collected and described many new species from India, which means that there might be some hidden syntypes in the material present at the herbarium in Oslo. The collections are not numbered which might further complicate the decision of the status of the specimens. J.D. Hooker's main affilation was to the botanical garden in Kew, where more of their material can be found. However, the value of the collections in Oslo is high as it might add to what is found in Kew. Their journeys are well described, so an approxiamate date to their collections can be found by tracing their journey. Major/Captain Francis Jenkins (1763-1866) and John William Masters (1792-1873) collected plant specimens in the area of Assam. F. Jenkins is credited for beeing the one that discovered the tea plant in Assam. Most of the collections present in Oslo was made by J.W. Masters, with little of no additional information other than the label shared with F. Jenkins "Coll. Jenkins Plants of Assam". They apparently did more collecting than describing. Thomas Anderson (1832-1870) is represented with a few collections in the herbarium. It seems like some former worker in the herbaria of Oslo confused him with the Swedish botanist Nils Johan Andersson (1821-1880), which was on a circumference within approximately the same time period. Some of their collections are quite presice and inludes the site and even the date of collecting, however others are of less precision. John Firminger Duthie (1845-1922), is strongly represented in the collection of material from India. Most of his collections are from the period of 1880-1900. Therefore the number of new species described by him is lower than the previous collectors for obvious reasons. His collections are very precise and includes both area and date of collection. One of the collectors from the early 1800's was Dr. Bernhard Schmid (1787-1857). Working as a missionary he mainly collected. But his material has been used by Jonathan Carl Zenker. The material is almost exclusively collected in the Nilagiri area. More recently, Robert L. Fleming collected many specimens in the Dehra Dun area about 1950, mainly pteridophytes. Ove Arbo Høeg a professor from the University of Oslo did some collections in 1951-1952. As these collectors are more recent, the labels are more detailed than the predecessors. In addition to these collectors which count for most of the material, several others have contributed. Mainly serveral persons from the University of Delhi, which mainly collected around Delhi, even on the University campus. A special case is that of Rudolph Friedrich Hohenacker (1798-1874). Many collections bears his label, but these are not collected by him personally. R.F Hohenacker sold flora exsiccata's which consist of specimens collected by other persons. The only additional information on these collections are the area they were collected. These collections have to be considered of lower scientific value than others, unless the original collectors can be traced, and therby giving a timespan and an actual collector. Final remarks: Many of the specimens from India in the herbarium of Oslo are from the 1800's and are therefore of a certain value. The possibility that some of them might be syntypes or isotypes adds additional value. And again for scientific purposes, material from India is rare outside India due to their export ban. Allthough it's not very useful for most modern DNA techniques, morphology is still the backbone of modern botany. It is also worth mentioning the "cool" factor of some of these collections. J.D. Hooker was one of Charles Darwins closest friends, which gives some perspective to what kind of material we are dealing with and help convey this era of botany.

The Herptile (reptiles and amphibians) Collection of the University Museum of Bergen
Our collections of amphibians and reptiles at the University Museum of Bergen, Norway are relatively limited in size: in total about 1200 specimens. Much of this material are whole animals preserved in ethanol. Even if the collection contains numerous species from exotic parts of the world, our main targets today are the limited number of species found in Norwegian fauna. Today there is no active collecting of herptiles at the University Museum and new material are mainly animals that have been found dead for various reasons.

Insects of the Forest-Tundra Ecotone (ForTunE)
The forest–tundra ecotone, which spans the whole northern Hemisphere, is the zone where closed forests gradually give way to open arctic or alpine tundra. In northern Norway, the forest–tundra ecotone is formed by three main vegetation types: (1) subarctic forests, where the canopy layer is formed almost exclusively by mountain birch; (2) a transitional zone of tall-shrub tundra dominated by diverse willow species in various combinations; and (3) arctic and alpine tundra, with low vegetation consisting of dwarf shrubs, herbs, grasses, mosses, and lichens. During the coming decades, the distributions of the different habitat types within the forest–tundra ecotone will change dramatically as a result of the warming climate. Especially open tundra habitats will shrink from their current extent due to shrub expansion. This may lead to significant losses of vertebrate and invertebrate species in open tundra habitats, but also of species living within other components of the forest–tundra ecotone. Predicting the effects of climate change requires detailed information on current diversity as well as the habitat and niche requirements of individual species. In our project, we use DNA barcodes to identify and to infer niches of insect species in different habitats within the forest–tundra ecotone. The first part of our project concentrates on the most important groups of plant-feeding insects in the north: butterflies and moths, symphytan hymenopterans (sawflies), beetles, leaf-mining flies, and hyperdiverse gall midges. In particular, we aim to barcode larvae collected directly from identified host plants, because the host plants determine the habitat(s) in which a given insect species can survive. In our second main line of investigation, we barcode hymenopteran and dipteran parasitoids reared from the herbivore larvae. Parasitoids are known to be hyperdiverse in subarctic and arctic environments, but are extremely difficult to identify based on morphological traits. Parasitoids constitute the main source of mortality for the larvae of other insects, so understanding parasitoid species richness and community composition in the forest–tundra ecotone will, for example, help to understand the regulation of moth outbreaks in mountain birch forests. Our barcoding project provides information on insect diversity in different habitats within the northern forest–tundra ecotone, provides genetic tools and reference databases for ongoing and planned environmental monitoring efforts, and results in data that can be used to estimate the threats that specific insect species, taxa, and communities face because of the warming climate of the future.

Vascular plants in power line clearings and the nearby forest, southeast Norway
Power line clearings are edge-creating disturbances in landscapes world-wide, but there have been few studies on their bordering vegetation. Our aim was to quantify edge effects on plant communities along such clearings in Norway and to identify factors that influence these edge effects. We surveyed understorey plant communities on either side of the power line clearing–forest edge at 51 sites, along four parallel transects at each site. Each transect had four plots located, respectively, in the clearing centre, clearing edge, forest edge and forest. We quantified the magnitude of edge effects (MEE) on either side by comparing edges with their corresponding ‘non-edge’ reference habitats. We also measured differences in species composition across the edge (clearing edge vs. forest edge). Habitat characteristics were sampled at plot and site level and from digital maps. % cover of vascular plants were registered (see Eldegard et al 2015 for description of study design and methods). Differences in species composition were greater between clearing centres and clearing edges than between forests and forest edges. Differences in species composition across the edge increased with edge contrast and forest productivity. Edge effects on species composition into the forest were smallest along north-facing edges, whereas those in the clearings increased with power line age. Species richness increased slightly towards the edge in forests but decreased considerably towards the edge in clearings. The direction and MEE on either side differed among functional groups. Edge contrast and edge aspect were the prime factors influencing the MEE into forests, whereas in clearings, these were influenced principally by tree regrowth in the clearings and by forest productivity. Synthesis and applications. Edge effects on plant communities bordering power line clearings were determined by factors that can be influenced by planners and managers. For existing power lines, management plans should differentiate between the following: (i) clearings through high conservation value forests, where edge effects into the adjacent forest should be limited; (ii) clearings that can act as replacement habitat for cultural landscape species, where maintaining open-canopy habitats should be prioritized; and (iii) ‘business-as-usual’ clearings, where continuing the current practice of cutting every 5–10 years is recommended.

Aim: The aim of this dataset is to provide a list of the Crop Wild Relatives (CWR) in the Nordic region that are most important for future food security, and to provide basic data on geographic distribution, gene pool affinity, invasiveness, and threat level. The dataset can serve as a basis for Nordic level, as well as national level, conservation planning and implementation. Method: A comprehensive CWR checklist for all Nordic CWR taxa was developed in 2017 (Fitzgerald et al., 2017). The taxa on this list were prioritized based on socio-economic value of the related crop(s) and potential utilization value of the CWR for breeding, resulting in the first version of the priority dataset. More information on how the prioritization was performed can be found in Fitzgerald et al. (2019). In 2021, an update of the dataset was made. Nordic scientists and plant breeders were contacted and asked if, in their opinion, there were taxa missing from the dataset. All suggestions were considered and evaluated for socio-economic value and utilization potential. The taxa deemed to fulfill the criteria were added to the list. Also, information on national threat category and national invasive category were added, and information on local names and geographic distribution were updated. Results: The result of the analysis is a list/data set of CWR prioritized based on socio-economic value of the related crop(s) and potential utilization value of the CWR. The list includes information on national occurrence (indigenous, naturalized foreign, temporary findings), to which genepool/taxon group the CWR belongs, use category (food/forage), national threat status and national invasiveness classification.

Rainforest and cloud forest Scolytodes (Curculionidae, Scolytinae, Hexacolini) from the Arthropods of La Selva inventory in Costa Rica: new species, new synonymy, new records
Quantitative collecting efforts over the last several decades in Costa Rica have resulted in many new species of insects. The Arthropods of La Selva projects included collecting from a typical lowland Neotropical forest and up an altitudinal transect, and has provided many valuable samples of insects, spiders and mites potentially new to science. We describe 18 new species in the bark beetle genus Scolytodes Ferrari, 1867, 14 of which were collected during this project: S. angulus Jordal & Kirkendall, sp. nov., S. sufflatus Jordal & Kirkendall, sp. nov., S. squamatifrons Jordal & Kirkendall, sp. nov., S. comosus Jordal & Kirkendall, sp. nov., S. spatulatus Jordal & Kirkendall, sp. nov., S. seriatus Jordal & Kirkendall, sp. nov., S. profundus Jordal & Kirkendall, sp. nov., S. catinus Jordal & Kirkendall, sp. nov., S. fimbriatus Jordal & Kirkendall, sp. nov., S. sulcifrons Jordal & Kirkendall, sp. nov., S. planifrons Jordal & Kirkendall, sp. nov., S. porosus Jordal & Kirkendall, sp. nov., S. mundus Jordal & Kirkendall, sp. nov., S. callosus Jordal & Kirkendall, sp. nov., S. parvipilus Jordal & Kirkendall, sp. nov., S. plenus Jordal & Kirkendall, sp. nov., S. niger Jordal & Kirkendall, sp. nov., and S. simplex Jordal & Kirkendall, sp. nov. One species, Scolytodes minutissimus Schedl, 1952, is redescribed to match the holotype. We give new Costa Rica records for S. costabilis Wood, 1974, which is the correct name for S. obesus Wood, 1975 (syn. nov.). We report Costa Rica as a new country record for six species: Scolytodes clusiacolens Wood, 1967, S. crinalis Wood, 1978, S. culcitatus (Blandford, 1897), S. libidus Wood, 1978, S. reticulatus (Wood, 1961), and S. spadix (Blackman, 1943). From a closely related genus, we provide the first record for Central America (and only the second collection) of Pycnarthrum fulgidum Wood, 1977.

Effects of vegetation clearing and dead wood on beetles in power line clearings southeast Norway
Linear habitats, such as power-line clearings, have been thought to affect biodiversity negatively. However, during the last decade several studies have highlighted the potential value of power-line clearings as habitats for a number of taxonomic groups, like bees and butterflies. The vegetation below power-lines is continuously reset to earlier successional stages, which provides suitable habitats for several native plant species, which hosts diverse assemblages of pollinating insects. In addition, the dead wood and biomass from the vegetation clearing, together with tree falls along the clearing edges may be important habitats for xylophagous beetles. With proper management, power-line clearings could be important for conservation of species associated with open-canopy habitats and dead wood. We conducted a large-scale field experiment, with 19 sites haphazardly distributed within the main power line grid in southeast Norway. All sites were placed below power lines in a boreal forest system consisting of varying proportions of the main tree species: Norway spruce Picea abies, Scots pine Pinus sylvestris and birch Betula spp. Sites were located between latitudes 59.33°–61.12°N and longitudes 08.95°–11.36°E at 48–536 m a.s.l., varying in width and age. Each site had been subjected to the same management regime with cutting of all woody vegetation every 5-10 years, without chemicals used, and had a stretch of at least 200 meters with substantial regrowth of trees before experiments were performed. At each site, we established three plots of approx. 30 x 60 m, at least 20 m apart. During late autumn 2012 (16 sites) and early spring 2013 (3 sites), treatments were randomly allocated to each of the plots within a site: 1) cut: woody vegetation was cut and left to decay in the plot, 2) cut-remove: woody vegetation was cut and removed, 3) Vegetation was uncut. Within a 10m × 10m plot in the centre of each treatment, we measured amount and type of dead wood (volume, species, diameter, degree of decay). In each experimental treatment, we also deployed insect traps (three flight intersection for trapping insects from spring to early autumn), and measured microclimatic conditions (light, temperature, precipitation) and various habitat attributes (tree layer characteristics, canopy density). Field data collections on vascular plants, insects, dead wood, habitat characteristics and microclimatic conditions have been collected over a three-year period (2013-2015). All insect specimen have been sorted into orders and all the beetles have been identified to species by Sindre Ligaard (Beetles: approx 48 000 specimen).

This study was performed at the southwest-exposed slope of Mt. Sanddalsnuten, in Southern Norway (60° 36' 55'' N, 7° 31' 8'' E) at approximately 1500 m a.s.l. The site has calcareous phyllite bedrock and is dominated by Dryas octopetala heath. The area is moderately grazed by domestic sheep and wild reindeer (Rangifer tarandus Linneus 1758). Lemming (Lemmus lemmus Linneus 1758) populations in Finse peaked in 2014, while other rodent species showed low abundances throughout the entire duration of the study. Ten blocks of four 1 × 1 m plots were randomly established in the Dryas heath. Within each plot, two permanent 60 × 30 cm vegetation-sampling subplots were established, separated by a 10 cm wide row. In 2004 and 2016, we sampled soil micro-arthropods in the row between the subplots.

Mound building termites contribute to savanna vegetation heterogeneity- woody plants, forbs and graminoids
With biomass densities comparable to large ungulates and megaherbivores, termites play a key functional role in many tropical savanna ecosystems. This study focuses on vegetated termite mounds (termitaria) constructed by the Termitidae species Macrotermes herus. We studied how resource rich termitaria affect graminoid herbs (Poaceae and Cyperaceae), forbs and woody species composition and diversity. The density of termitaria explained 89% of the variation in dense thickets in the area. Fire tolerant Acacia species dominated the open savanna while fire sensitive species like Grewia spp. and the succulent Euphorbia candelabrum were restricted to termite mounds. Termitaria plots had four times the mean number of woody species and supported three times as many forb species as the adjacent savanna. For woody species, both the Shannon–Wiener index and the Shannon evenness index were higher on temitaria than on the savanna. There were no differences for graminoid herbs, except for the Shannon evenness index which was higher on termitaria. Our results indicate that graminoid herb richness peaks at lower productivity levels than trees and forbs in savanna ecosystems, as also recently found in temperate areas.

Bryophyte herbarium TRH, NTNU University Museum
The TRH bryophyte herbarium contains specimes of Bryophyta, Marchantiophyta and Anthocerotophyta from most parts of the world, but is best represented for the Northern Hemisphere and especially northern parts of Europe. Almost the whole collection has been digitized. The oldest specimens in the collection is by Hans Strøm from 1745. Collections from the late 1800s and early 1900s comprise the foundation of this collection, primarily through the work of Ingebrigt Severin Hagen who worked at the NTNU University Museum from 1907 until his death in 1917. There was also a peak in activity from 1970-1980 mainly due to the joint efforts of A.A. Frisvoll and K.I. Flatberg. After 1998 the activity has again increased meaning that we have a relatively high proportion of recently collected specimens. Taxonomically Bryophyta constitute about 75% and Marchantiophyta 25% of the collection, with Anthoceratophyta with less than 1%. These numbers roughly represent the species diversity of the main taxonomic groups at northern latitudes. Sphagnum is particularly well represented with more than 25 000 specimens. Much of this is of rather recent date and a result of the taxonomic research by Kjell Ivar Flatberg. Schistidium and Racomitrium are other well represented genera due to the taxonomic work of Hans H. Blom and A.A. Frisvoll. The collection includes more than 2000 type specimens of bryophytes. The top ten countries/areas are: Norway, Svalbard with Jan Mayen, Sweden, United States of America, Canada, Germany, Greenland, France, Iceland and the Russian Federation. Svalbard is very well represented with close to 20 000 occurrences, the main contributor to this material is Arne A. Frisvoll that visited Svalbard and Jan Mayen several times during the 1970’s. Important exsiccatae includes: Hepaticae Europaeae Exsiccatae, Victor F. Schiffner Musci Alleghanienses, William S. Sullivant Musci Europaei Exsiccati, Ernst Bauer Bryotheca Bohemica. Laub- und Lebermoose aus Böhmen in getrockneten Exemplaren, Bauer, Ernst Musci Frondosi Archipelagi Indici Exsiccati, Max Fleischer Bryotheca Europaea Meridionalis, Fleischer, M.; Warnstorf, C.F.

Taxonomy and vertical export rates of protist cells, planktonic protist carbon (PPC) and zooplankton abundance and biomass from long-term sediment traps in the shelves north and east of Svalbard, as part of the Nansen Legacy project and the Arctic PRIZE project
This dataset includes taxonomy and vertical export rates of zooplankton abundance and biomass from long-term sediment traps between October 2017 and September 2018. Samples were collected from 2 moorings as part of the Arctic PRIZE project (SAMS, UK) and the sediment traps were processed as part of the Nansen Legacy project (UiT, NO). Records in the dataset can be divided into 2 moorings by the locationID column, either ESv (shelf east of Svalbard) or NSv (shelf north of Svalbard). For the ESv mooring, the mooring was deployed in 183 m water depth on 21 September 2017 north of Svalbard from the R/V Lance (A-TWAIN cruise). The mooring was recovered by the R/V James Clark Ross (JR17006) on the 17 June 2018 and sensor data were retrieved and instrument batteries replaced for redeployment on the 20 June 2018. A final recovery of all sensors was done by the R/V Kronprins Haakon (Nansen-Legacy cruise) on 18 November 2019. For the NSv mooring, the mooring was deployed in 234 m of water on 23 September 2017 north of Svalbard from the R/V Lance (A-TWAIN cruise). The mooring was recovered by the R/V James Clark Ross (JR17006) on the 14 June 2018 and sensor data were retrieved and instrument batteries replaced for redeployment on the 22 June 2018. A final recovery of all sensors was done by the R/V Kronprins Haakon (Nansen-Legacy cruise) on 25 November 2019. Samples were taken from a long-term sequential sediment trap bottles (McLane Research Laboratories Inc., 21 bottles, aperture area of 0.5 m^2). Sample bottles (500 mL) were programmed to rotate at intervals ranging from 7 to 31 days. Sample bottles were filled with filtered seawater poisoned with formalin (4% v/v), with the salinity adjusted to 40 by adding NaCl. For the zooplankton, subsamples (100-150 mL) were taken for the analysis of a minimum of 300 zooplankton. Zooplankton were identified to the lowest taxonomic level possible using a stereomicroscope (Zeiss Discovery V20) and measured with an accuracy of 10 μm using the ZoopBiom digitizing system (Roff & Hopcroft, 1986). Biomass (dry weight) was estimated using published length-weight regressions for these or similar species (Ershova et al., 2015). The dry weight of each taxon was then converted to carbon weight following Kiørboe (2013). Species were also classified by biogeographic affinity. Samples (0.5-2 ml) for planktonic protists identification were settled in Utermöhl sedimentation chambers for 24 h. Settled protists were counted using an inverted microscope equipped with phase and interference contrasts (Nikon Eclipse TE-300). Microplankton (>20 μm) was enumerated from the entire chamber surface at 100× magnification. Nanoplanktonic protists (3–20 μm) were counted at 400× magnification by moving the field of view along the length of three transverse transects (in special cases a magnification of 600× was used for taxonomic identification). The taxa were identified to the lowest taxonomic level possible following the World Register of Marine Species (WoRMS). Planktonic protist carbon (PPC) was calculated by multiplying the cell counts of individual cells and resting spores by the associated carbon content of each species or group depending on cell sizes (Menden-Deuer & Lessard, 2000). All daily fluxes (vertical export rates) were calculated depending on the volume of the subsamples, the trap area (0,5 m), and the sampling duration.

Algae herbarium TRH, NTNU University Museum
The algae collection contains various groups of photosynthesizing organisms not belonging to vascular plants, bryophytes or lichens. The three best represented groups are the red algae, green algae and brown algae. The main part of the collection was established by Mikael H. Foslie (1855-1905). Foslie was an internationally recognized expert on coralline algae and received objects from colleagues and expeditions from all over the world. The coralline algae collection by Foslie is kept as a separate collection consisting of nearly 4000 specimens, including about 550 types. A catalogue of the collection was published in Gunneria in 2005. The other parts of the algae collection mainly consist of algae collected along the Norwegian coast. In addition to the 550 types of coralline algae in the Foslie collection, we have 150 type specimens of other algae. Important exsiccatae includes: Phycotheca Boreali-Americana.

The importance of host tree age, size and growth rate as determinants of epiphytic lichen diversity in boreal spruce forest.
The amount of large and old trees has decreased in the boreal forests during the last centuries of forestry. Such trees are important habitats for epiphytic lichens and there is a growing concern for lichen species that are associated with large and old trees. However, only little is known about the relative importance of tree size versus age as determinants of lichen diversity. Here we have determined the size, age and growth rate of 157 Norway spruce trees and recorded the occurrence of epiphytic lichen species on their branches and lower stems. The study includes crustose lichens and was done in two old-growth forests in SE Norway. Tree age and tree size were the parameters that explained the largest part of epiphytic lichen diversity. Only the growth rate of the most recent time period, i.e. 1984-2004, showed a statistically significant relationship to diversity. There was no indication of a stabilising species number with increasing tree age. Slow-growing and old trees were, however, mainly of importance to the lichen species growing on stems, and this set of species were in general adversely affected by a large amount of branches. The opposite was the case for the species that were confined to branches as their diversity increased when the amount of branches increased. Our study adds empirical data to support the importance of large and old trees as bearers of biodiversity in boreal forests. Site preservation and patch retention of groups of old and large trees is recommended as measures to maintain epiphytic lichen diversity.

Protist community composition in the water column on the East Greenland shelf, May 2022
The community composition of suspended protists was investigated at 3 stations on the East Greenland continental shelf as part of the EU project ECOTIP. Water was sampled with a 1.7 L Nansen Water bottle at the stations LCC1 (13 May 2022), LCC2 (14 May 2022), and LCC3 (17 May 2022) at 5, 15, 35 m. At station LCC2, a sample was also collected at 90 m. Water samples were collected through a hole in the land-fast sea ice at station LCC1 and LCC2 and from a ship at station LCC3 (station located in a polynya outside Scoresby Sound). The collected water was gently transferred into a carboy, which was stored cool (not freezing) and in darkness until handling within few hours. From each carboy, a subsample of 100 mL was transferred into a glass bottle, preserved with 1 mL acidic Lugol’s solution for later microscopic analysis. The CTD data from the stations and the suspended concentration of chlorophyll a (> 0.7 micrometer and > 10 micrometer) as well as the organic carbon and nitrogen can be found in the NIRD research data archive (https://doi.org/10.11582/2023.00046 and https://doi.org/10.11582/2024.00037).

Microsetella norvegica at station Svartnes, Balsfjord, Norway in June 2017 and June 2018 (sampled with a GoFlow bottle)
In the project MICROSNOW the ecological role of the small copepod Microsetella norvegica in the sub-Arctic Balsfjorden, Norway, was investigated. Since M. norvegica is often undersampled in net hauls with a standard WP-2 net (180 µm mesh size), this project collected zooplankton water samples with a 30 L GoFlow bottle at distinct depths (0, 10, 20, 50, 90, 120 m). From the collected water, 20 L were concentrated onto a 20 µm mesh sieve, the collected zooplankton was preserved with buffered formaldehyde and later different developmental stages of M. norvegica were enumerated (adult male, adult female, copepodite stage CIV- CV, copepodite stage CI-CIII, nauplius). Under the projectID "Microsnow_2017_2018_Balsfjord" there is also an an additional data set on the zooplankton community composition at the same station (WP-2 net, 64 µm mesh size) available on GBIF.

Overwintering survival of soil microarthropods under differing natural snow covers
The Arctic has a diverse terrestrial microarthropod fauna which overwinters in situ in soil and vegetation. This fauna is involved in key ecosystem process, for example decomposition and pollination, and has tolerance to the Arctic’s winter conditions. However, the Arctic is undergoing rapid change. Svalbard is experiencing warming rates up to four times the global average as well as alterations in precipitation (quantity and form; snow or rain) and wind direction. These will modify the conditions experienced by the overwintering fauna. Since laboratory experiments often fail to capture the diversity of environmental stressors, we employed a manipulation experiment to use the naturally accumulating snow pack to moderate soil winter soil temperatures, combined with an extended incubator treatment, to map the duration limits of naturally induced cold tolerance. We demonstrate that the Collembola fauna can tolerate temperatures of -25°C but that, in areas devoid of snow accumulation and when soil temperatures dip below -30°C there is significant mortality. Furthermore, we demonstrate that exposure to a further extended 12 month period at -6°C, as a simple model of a situation where snow cover is not lost during the short Arctic summer, results in additional mortality with relatively few Collembola surviving. By contrast, while oribatid mites displayed similar survival over a natural winter as the Collembola, they were highly resistant to the extended exposure at -6°C, with no additional mortality occurring. We also documented survival amongst other invertebrate groups, including Nematocera and Brachycera larvae, Hemiptera (A. svalbardicum), Coleoptera (I. flagellum), and Araneae (Linyphiidae). We conclude that snow depth and winter air temperatures interact to regulate soil microarthropod populations over local scales and the functioning of the Arctic soil ecosystem. Moreover, the environmental changes currently being observed in polar regions will continue to modify this fauna and its local and micro-scale distribution.

Marine bottom organisms in prospective marine protected area Froan-Sularevet, Norway
Occurrences of marine bottom organisms at 20–500 m depth in the Froan-Sularevet area outside Frøya in Trøndelag, Norway from 30 August – 9 September 2025. The study area is in or near a proposed marine protected area: https://faktaark.naturbase.no/?id=VP00001512 The data was collected by Akvaplan-niva during an underwater video survey of 18 transects with a remotely operated diving vessel (ROV). Taxonomic identification was done in the field, by an expert in vulnerable marine organisms, from high definition video from the ROV. Depth and position was obtained via the ROV's navigation software (EIVA NaviPac) and later corrected. When possible, each individual organism was identified and the number of organisms present in one second of video is reported in individualCount. Some organisms, were uncountable using visual inspection and are recorded as present with no individual count. These are coral Clavularia borealis , kelp species Laminaria hyperborea , Saccharina latissima , and stony corals. Desmophyllum pertusum , and Madrepora oculata . Taxonomy is validated against World Register of Marine Species (WoRMS) using GBIF Species API. The final Darwin Core occurrence data is validated against GBIF data validator service prior to publishing.

## Methods ### Study area This dataset is the result of a sampling program in Isfjorden on the west coast of Spitsbergen, Svalbard. ### Time coverage The sampling was conducted in 2016 and 2017, with one sampling per season; summer and autumn in 2016 and winter and spring in 2017. ### Sampling 50 sea water samples were collected at two stations named "n1" and "s2". On each sampling date three sampling protocols were used: - a fine net deployed horizontally by a diver (100 µm mesh) - a specialized water pump (hoover/vacuum, 100 µm) deployed at a certain depth - vertical plankton net tows (WP2-net, 65 µm). Both the diver's net and vacuum pump sampled from 6 and 12 meters depth at each station, while the WP2-net sampled from 50 to 0 meters and from 12 to 0 meters depth. For station "s2", the sampling at 6 meters with a diver's net and vacuum pump was carried out in the autumn of 2017 and not together with the other sampling that occurred in the autumn of 2016. ## Taxonomy The dataset was analysed using image analysis software (Ecotaxa) with subsequent expert validation. ## Data ## This dataset is built using a [fully automated processing pipeline](https://github.com/akvaplan-niva/gbif-no-darwin-core/blob/main/bin/ecotaxa-pipeline), using the [ecotaxa-occurrences](https://github.com/akvaplan-niva/ecotaxa-darwin-core#ecotaxa-occurrences) ## Processing https://doi.org/10.5281/zenodo.4700253 This dataset contains two Darwin Core distributions - dwc-ndjson: Newline separated JSON (NDJSON) - dwc-a: Darwin Core archive (TSV/XML) command line tool.

Vegetation data with and without experimental warming, alpine Finse 2000, 2004, 2011
Vegetation data with and without experimental warming, collected in Finse in 2000, 2004, 2011, under a project called “Experimental warming in alpine Dryas heath”. The seed-addition and warming experiment was conducted at Finse (60°36′59″N, 07°31′23″E) in the alpine region of southern Norway, established in 2000. During summer, (June–August) Finse has a mean monthly temperature and rainfall of 6.3°C and 89 mm, respectively. The study site is located at approximately 1550 m a.s.l. on an exposed ridge of Mt Sanddalsnuten (peak at 1556 m a.s.l.). The bedrock consists mainly of phyllite, supporting a species rich Dryas heath community. The vegetation is dominated by the dwarf shrub Dryas octopetala, and other common species are Bistorta vivipara, Carex rupestris, Carex vaginata, Saussurea alpina and Thalictrum alpinum. The experiment was initiated in 2000 to study the relative impacts of seed dispersal and different biotic and abiotic factors on plant species richness. They established 80 main plots, each of which consisted of two 30 × 60 cm split-plots which were further divided into eighteen 10 × 10 cm subplots. One of the split-plots in each main plot was randomly selected for seed addition, while the other was used as a control for natural background recruitment. Seeds and propagules (from here on collectively called seeds) were collected of 27 species at Mt Sanddalsnuten and randomly varied the number of species added to each split-plot to study the effect of seed species richness on community species richness. Each seed-addition plot received 0, 3, 6, 9, 12, 15, 18, 21, 24 or 27 species as seeds, with eight replicates per level of seed-addition. Eleven of the added species were not present in the plots prior to seed addition (Table 1). To examine whether warming affected the relative importance of dispersal and environmental filtering for species richness, open- top chambers (OTCs) open- top chambers (OTCs) were randomly placed upon half of the main plots. OTCs are hexagonal polycarbonate chambers with an inside diagonal of 1 m used for experimental warming of vegetation (see for instance Marion et al. 1997). Collection methods: species abundance by subplot frequency.

Macrozooplankton at the Barents Sea Polar Front in January 2024
## Methods ### Study area This dataset includes the results of sampling at six stations along a transect in the western Barents Sea. Some stations were trawled twice at different depths . ### Time coverage The samples were collected between 09 January 2024 and 11 January 2024. ### Sampling Nine macrozooplankton samples were collected with a Tucker trawl (1 m2 opening and 1000 μm mesh size). Tows were on average 10 minutes at the target depth and at ca. 2 knots. The targeted depth at each station was determined from the sound scattering layer identified in the echogram from the vessel's echosounder. ### Sample analysis Tucker trawl samples were analyzed per station, and taxa were enumerated and dried at 60 C° for at least 48 hours, in pre-weighted recipients for dry weight measurements post cruise. The obtained abundances were standardized and converted to catch per unit effort, expressed in milligrams per cubic meter.

Small rodents trapped in old growth forest in Vegårshei, Norway
Small rodents trapped in old growth forest over several years from 1999 to 2016. Specimen have been collected at ten different sites in Vegårshei (Aust-Agder county), but some of the localities have changed over the years due to clear cuts. Each year, 100 traps, baited with carrot, have been put out for 4 days and nights, during summer season. The main species, Myodes glareolus and Apodemus sylvaticus, have been identified and counted.

On 26 August 2016, lightning killed 323 reindeer near the Vesle Saura Lake in the southern part of Hardangervidda. The carcasses were distributed over an area of 240 x 100 square m, with the highest concentration comprising about 50 x 50 sq m. The REINCAR Project established 75 permanent monitoring plots in a semi-regular grid covering the entire area. Of the 75 plots, 30 were used for trapping arthropods using pitfall traps. The traps had a diameter of 9 cm and were at 7 cm deep. Beetles were sampled at the carcass site and at a control site 500 meters apart.

Semi-naturlig eng er en sjelden naturtype i Norge med et høyt biologisk mangfold. Naturtypen er i sterk tilbakegang og truet, men det mangler arealrepresentative tall for denne tilbakegangen og tilstanden til gjenværende arealer. Siden semi-naturlig mark bare utgjør 1 % av det totale landarealet i Norge, er det ikke sannsynlig at nasjonal arealrepresentativ naturovervåkning (ANO) vil gi nok data til å utvikle holdbare tilstandsverdier for denne naturtypen. Arealtyperepresentativ overvåking er derfor nødvendig for å skaffe til veie et godt datagrunnlag. Derfor er det utviklet en metode for slik overvåking av semi-naturlig eng i Norge.

Acoustic data were recorded at the Johan Castberg field in the southern Barents Sea at three locations from October 2018 until June 2019 to assess the presence of marine mammals and characterise the underwater soundscape. The marine mammal analysis was focused on two stations (PAMEast and PAMNorth) as the third (PAMWest) stopped recording early and the data suffered from poor audio quality. Five marine mammal species were detected during the study: fin whale, humpback whale, killer whale, sperm whale and a dolphin species whose signals were tentatively attributed to white-beaked dolphins on the basis of sighting records in the area and habitat preference of this species. These species were generally detected at similar levels at PAMEast and PAMNorth, except for dolphins, which were more common at PAMNorth. Dolphins showed a pronounced seasonal pattern of occurrence, with very few detections in winter. Killer whale occurred sporadically, their occurrence peaking in November and March, possibly coinciding with that of prey species. Along with dolphins, sperm and fin whales were the most commonly detected species, occurring throughout the study, albeit slightly less frequently in late winter than during the rest of the year. Humpback whale detections peaked in March, which may be associated with the transit of migrating animals through the area as they return to feed on spring spawning herring.

Øvre Heimdalsvatn, Radiocaesium (Cs-137) monitored annually in brown trout (Salmo trutta)
"This dataset describes a long time serie for monitoring of radioactive radiocaesium isotope (Cs-137) concentration in the brown trout (Salmo trutta) population in a mountain lake (Øvre Heimdalsvatn) situated on the tree line in the eastern edge of the Jotunheimen Mountains. Ecosystem studies at Øvre Heimdalsvatn started in 1957, while this time series for radioecological monitoring started after the Chernobyl nuclear power plant accident in 1986. The aim of this study was to document the long-term changes in the radioactive isotope Cs-137 in brown trout and to elucidate the factors determining changes in Cs-137 activity concentrations over time. This dataset provides only one time serie from the extensive ecosystem studies (initiated in 1957) at Øvre Heimdalsvatn. The mountain lake is at 1090 meter above sea-level with a surface area of 0.78 square kilometer (km2) (78 hectare). The maximum length is 3 km and the maximum width is 396 m. The largest depth is 13 m and the average depth is 4.7 m. Vegetation near the lake ranges from subalpine birch forest with areas of mountain pasture to high alpine vegetation above 1,600 m a.s.l. Originally brown trout was the sole fish species in the lake, but since 1969 the European minnow (Phoxinus phoxinus) has also been recorded and its numbers have subsequently increased substantially. Brown trout for this study were generally caught by gill netting around the lake."

Nordic Crop Wild Relative (CWR) Checklist
The Nordic Crop Wild Relative (CWR) checklist is a result of a joint Nordic project, "Ecosystem services: Genetic resources and crop wild relatives" (2015-2016) funded by the Nordic Council of Ministers and the Nordic Genetic Resources Center (NordGen). A Crop Wild Relative (CWR) is a wild species that is closely related to a cultivated crop. This close relationship means that properties in a CWR can be transferred to the crop by traditional crossings. As modern cultivars may lack the desired variation, the diversity found in CWRs can be central for adaptation to new demands on the crops.

Savanna herbaceous vegetation, Lake Mburo National Park, Uganda
Termites and large herbivores represent important functional groups in savanna ecosystems. Termites affect vegetation far beyond their mounds. In addition, large herbivores feed selectively on termite mound vegetation or in the vicinity of mounds. Previous studies of savanna vegetation communities have focused on termites and large herbivores separately, although interaction effects may be predicted. We studied the effects of large herbivores and large vegetated Macrotermes mounds on the herbaceous vegetation in Lake Mburo National Park in Uganda. We recorded herbaceous vegetation change over 3 years on savanna areas (with and without large herbivores) and on corresponding termite mounds (with and without large herbivores) in a randomized block design. Termite mounds and savannas had significantly different plant communities, but large herbivore grazing exclusions did not result in significant shifts in plant communities during this study period. A canonical correspondence analysis separated species mainly along an axis from termitaria to savanna. Only a few species responded to grazing exclusion. Some erect species, such as Hyparrhenia filipendula and Themeda triandra, increased in cover, and creeping species, such as Cynodon dactylon, decreased, following the exclusion of grazers. Forbs dominated mound areas, while graminoids dominated the savanna areas. Fencing increased the cover of graminoids over time and led to gradual increase in the relative cover of graminoids compared with forbs. Mound soil was higher in pH, calcium and magnesium and lower in sodium compared with adjacent savanna areas. Nitrogen and carbon soil content did not differ between the two habitats. Soil phosphorus increased following grazing exclusion. This study shows that termites may exert a far more important effect on the herbaceous community than large herbivores in savanna areas, even if the biomass of large herbivores is relatively high. Thus, future studies on savanna vegetation ecology should focus increasingly on important insect groups in addition to the more conspicuous large mammal guild.

Mesozooplankton abundance, biomass and copepod secondary production at the Barents Sea polar front, June 2011
Mesozooplankton (0.25-4 mm) abundance (ind. m-3) and biomass (mg C m-3) and copepod secondary production (mg C m-3 d-1) at four stations (M1-M4) across the Barents Sea polar front, covering Atlantic to Arctic waters (75-78 °N) in June 2011. Mesozooplankton was sampled with a WP-2 net (Hydro-Bios) with 180 µm mesh, 0.57 m diameter net opening and filtering cod-end. Filtration volume was estimated from opening diameter and sampling depth. Three vertical net hauls were taken during day (around noon, WP2-day) and during night (around midnight, WP2-night) at all stations, at fixed depth intervals of 0-50 m, 50-100 m, and 100m-bottom by using a closing mechanism. The content of the cod-end was concentrated over a 90 µm mesh on deck and preserved with buffered formaldehyde at 4 % final concentration. To increase the resolution in the surface and to quantitatively sample the small copepod species and young developmental stages, one GoFlo profile was sampled at daytime at each station in the upper 50 m. Samples were taken from 1, 10, 20, 30, 40 and 50 m depth. The content of the water bottle (30 liters) from each individual depth was concentrated over a 20 µm mesh and preserved with buffered formaldehyde at 4 % final concentration. Mesozooplankton were counted and determined to species and developmental stage under a Leica dissecting microscope at 40x magnification. Mesozooplankton abundance was converted into biomass, based on species and stage-specific carbon weight relationships. Daily copepod secondary production (mg C m−3 d−1) in the upper 50 m water column was calculated as the sum of the product of biomass and weight-specific growth rate of each individual stage within the copepod population. Copepod growth rate was determined using four different growth rate models, namely Hirst & Bunker 2003 (HB_copepod_secondary_production, based on copepod body weight, chlorophyll a concentration, in-situ water temperature), Hirst & Lampitt 1998 (HL_copepod_secondary_productioncopepod, based on body weight, in-situ water temperature), Huntley & Lopez 1992 (HuLo_copepod_secondary_production, based on in-situ water temperature) and Zhou et al. 2010 (Zhou_copepod_secondary_productioncopepod, based on body weight, chlorophyll a concentration, in-situ water temperature, assimilated food input).

The biodiversity of invertebrate parasites is an important factor in ecosystem health. This project targets the Norwegian gyrodactylid fauna. This group of ectoparasites of fish and cephalopod molluscs includes the major pathogen Gyrodactylus salaris on salmon and the emerging pathogen Gyrodactylus marinus on cod. Overall the genus Gyrodactylus is poorly known and many species and parasite strains await proper description. This is particularly true for the gyrodactylids on Norwegian marine fishes, where perhaps up to 50 species remain to be catalogued, and several species new to science are to be expected. This project adopts a novel approach, screening the fish collection of the Natural History Museum Oslo that has a comprehensive representation of the Norwegian fish fauna for gyrodactylids. These parasites will then be described using advanced morphometric and molecular approaches. We aim at developing towards a comprehensive picture of the Norwegian gyrodactylid fauna of both freshwater and marine fishes, and expect to add morphometric and molecular descriptions of some 30-50 species (including some new to science) to the Norwegian fauna lists.

Long-lasting effects of logging on beetles in hollow oaks
Habitat loss is currently one of the largest threats to biodiversity worldwide, but an increasing number of studies show that accounting for past habitat loss is essential to understanding current distributional patterns. Hollow oaks (Quercus spp.) are important habitats for species that depend on deadwood. We used a gradient spanning 40 km from the coast to inland areas reflecting historical logging intensity through 500 years in Southern Norway, to investigate if the historical variation in oak density is influencing the structure of beetle communities in hollow oaks today. We trapped beetles in 32 hollow oaks along this gradient. The current dataset contains data from 2014, but not 2013 which also was included in the study (and is available through Norway's Species Map Service, http://artskart.artsdatabanken.no). We selected hollow oaks Quercus robur and Q. petraea along a coast-inland gradient in two regions, Agder and Larvik, in southern Norway. Agder is situated in the south, with hollow oaks from the coast to 40 km inland, while Larvik is located in the southeast with hollow oaks from the coast to 25 km inland. We sampled 16 hollow oaks in each region. Our study included trees in forest (n = 17) and semi-natural habitats (n = 15). The latter represents oaks in forest edges along fields or close to settlements. Each oak was sampled for insects using two flight interception traps (window size 20 × 40 cm) for each oak, one in front of the cavity opening and one in the canopy. The insect traps were active from mid-May to mid-August in 2014, and emptied once a month. All beetle species caught were determined to species.

20th century Betula pubescens ssp. czerepanovii tree- and forest lines in Norway
Georeferenced tree- and forest line data has a wide range of applications and are increasingly used for e.g. monitoring of climate change impacts and range shift modelling. As a part of a research project, registrations of previously re-mapped tree- and forest lines have been georeferenced. The data described in this paper contains 100 registrations of Betula pubescens ssp. czerepanovii throughout Norway. All of the re-mapped tree- and forest line localities are georeferenced, elevation and exposition is given, elevational and spatial uncertainty is provided, and the re-mapping methods are explained. The published data has been gathered from 1928 until 1996, but has until now been missing spatial coordinates. The entries contain 40 tree lines and 60 forest lines. The entire material is stored and available for download through the GBIF server.

Redlisted beetles found in oak grove near Lake Østensjø
Data obtained from an insect survey of the oak grove in the ‘environmental park’ around Lake Østensjø (established 2002). “Østensjøvannets Venner” initiated the survey in 2014 to document the species diversity particularly in relation to a few large and potentially hollow oak trees. The aim of the survey was to identify which beetle species associated with dead wood exists in this area. Four insect traps (window traps) were put out at three different oak-tree locations, in the beginning of May to the end of August 2014. The traps were emptied every second week during this period. Sindre Ligaard identified the beetles. Totally 45 beetle species were found.

Zooplankton community composition in Svartnes, Balsfjord, Norway in June 2017 and June 2018 (sampled with a WP-2)
In the project MICROSNOW, the zooplankton community composition at station Svartnes in Balsfjorden was investigated in June 2017 and June 2018. Balsfjord is a 57 km long, narrow fjord with a shallow sill (35 m) and the bottom depth at the sampling station Svartnes is 190 m. The zooplankton was collected in vertical hauls of a WP-2 zooplankton net (mesh size 64 µm). The sampling was done in sets, consisting of deep haul (170 - 50 m) and shallow haul (50 m - surface). In 2017, 5 sets of zooplankton hauls were done (two sets on 20 June 2017, three sets on 21 June 2017) to investigate potential changes of the community composition throughout the day. In 2018, only one set (deep + shallow haul) was collected (12 June 2018). Under the projectID "Microsnow_2017_2018_Balsfjord" in GBIF also an additional data set on Microsetella norvegica (developmental stage composition from samples collected with a 30 L GoFlow bottle) is available.

Phytoplankton community composition in the water column of the West Greenland shelf, July 2021
The community composition of suspended phytoplankton cells was investigated at 10 stations on the West Greenland continental shelf as part of the EU project ECOTIP. Water was collected with a 12 L Niskin bottle at or close to the fluorescence maximum (between 20 and 50 m). Onboard the ship, the water was gently transferred into a carboy. From each carboy, a subsample of 100 mL was transferred into a glass bottle, preserved with 1 mL acidic Lugol’s solution for later microscopic analysis. From this field campaign, a cruise report is publicly available on Zenodo (https://zenodo.org/doi/10.5281/zenodo.5913276). In addition, the following data sets are available: 1) the concentration of suspended chlorophyll a (Chl a >0.7 and >10 micrometre), phaeophtin (Phaeo >0.7 and >10 micrometre), particulate organic carbon (POC) and nitrogen (PON) in the water column (https://doi.org/10.11582/2024.00039), 2) the downward flux of Chl a (>0.7 and >10 micrometre), Phaeo (>0.7 and >10 micrometre), POC and PON at three stations (https://doi.org/10.11582/2024.00041), and 3) the community composition of sinking protist cells on (https://doi.org/10.15468/kw3rs9).

MATRIX project, monkeys near Kampala in Uganda
Monkeys were counted along transects using standard primate census techniques twice a month for nine months, starting October 2011. Transect lines (Buckland, Plumptre, Thomas, & Rexstad, 2010) were established in each forest patch along which monkey censuses were conducted. The number and length of the transects was dependent on the size of the forest patch, following the longest distance across the forest. The census was done between 0700hrs and 1100hrs and later between 1500hrs to 1900hrs since the monkeys tend to be more active in the early morning and late afternoon (Davies & Hoffmann, 2002). During each census, the transect was walked at approximately 1km/hr and all observed monkeys were recorded.

Spatial and temporal project data (EVENT DATA) from 280 marine sampling events. Marine benthic invertebrates were collected during annual summer period cruises 1950-1953 with research vessel R/V “G.M. Dannevig”. The sampling effort was organised by the Natural History Museum in Oslo. The cruises covered Norwegian coastal areas from the mouth of the Oslofjord to Kvitsøy on the west coast. This dataset is deliberately published WITHOUT OCCURRENCES. The collected invertebrate material was to be made available for revisions by specialists. It was further intended that the collections should form a core material for a series of publications on Nordic marine fauna named ‘Marine Invertebrates of Scandinavia (MIOS)’. Ten volumes were published, but the original idea of a series covering more than 40 systematic groups was never completed. The collected material was deposited in the invertebrate collections of the Natural History Museum of the University of Oslo. Parts of the material has not yet been registered. Parts has been registered but is still to be digitised (status per 2018). It will be published in GBIF as occurrence files which will be linked to these datasets using the corresponding eventID. So far, occurrence data of several polychaete families have been published: https://ipt.gbif.no/resource?r=polychaeta

Quantitative Invertebrate megabenthic data from the Nansen Legacy project collected in 2018 cruise JC2-1 with bottom Campelen trawl from R/V Kronprins Haakon.
Mega-benthos was sampled from the seabed by the Nansen Legacy joint cruise 1-2, on R/V Kronprins Haakon, 6-23 August 2018 (Cruise 2018707). A Campelen 1800 bottom trawl was used after rigged with rock-hopper ground gear and towed on double warps. The mesh size was 80 mm (stretched) in the front and 16–22 mm in the cod end. The horizontal opening was 11.7 m, and the vertical opening 4 –5 m. The trawl configuration and bottom contact was monitored remotely by SCANMAR trawl sensors. The standard procedure is to tow 15 min after the trawl had contacted the bottom with towing speed of 3 knots, equivalent to a towing distance of 0.75 nautical miles (1.4 km) during a 15 min tow. The trawl settings allow the capture and retention of small-sized fish and the largest benthos (benthic megafauna) from the seabed. In addition, the trawl may also be contaminated by organisms entering the trawl when it is lowered or heaved. The sample was sorted, and each benthos taxon was counted and weighted (i.e., biomass is wet mass) and identified to closest possible taxa onboard the ship. The count of individuals per species/taxa in the trawl (Tot abun) and the wet-weight of the individuals per species/taxa in the trawl (Tot weight (kg)) was recorded. A total of 100 taxa (14 phyla, 28 taxonomic groups), were recorded with 30-46 taxa at each of the five stations. A total of 193 kg mega-benthos was collected with 15 to 88 kg wet weight per station. A total of 40.661 individuals were collected with 2.219 to 18.086 individuals per station. The hauls were standardized to a fixed sampling effort of one nautical mile: abundance per species/taxon as number of individuals per nautical mile and biomass per species/taxon as kg wet weight per nautical mile.

Solhomfjell forest floor species composition 1988-2018
Økland, R.H. & Eilertsen, O. 1993. Vegetation-environment relationships of boreal coniferous forests in the Solhomfjell area, Gjerstad, S Norway. - Sommerfeltia 16: 1-254. Oslo. ISBN 82-7420-018-7. ISSN 0800-6865. The understory vegetation (vascular plants, bryophytes and lichens) in an area dominated by boreal coniferous forests is subjected to detailed ecological analysis. Two hundred meso sample plots (1 m2) are used as basis for vegetation sampling, and provided with measurements of 33 environmental variables. Species abundance is recorded as frequency in 16 subplots. Parallel DCA and 2-dimensional LNMDS ordinations of meso sample plots were largely identical, both provided two coenocline axes interpretable in ecological terms. The first axis is interpreted as the response to a broad-scale topographical complex-gradient, made up of two independent complex-gradients; (1) a topography-soil depth complex-gradient in the pine forest (running from lichen-rich pine forests to submesic Vaccinium myrtillus-dominated spruce forests), and (2) a complex-gradient in soil nutrient status in the spruce forest. The second axis, mainly affecting the species composition of the bottom layer, is interpreted as a fine-scale paludification gradient. The causes of variation along these gradients are discussed: Desiccation tolerance is considered to act directly on the physiology of vascular plant species, setting their limits towards xeric sites. Similarly, cryptogams with optima in the more mesic sites are considered to be excluded from drier sites by physiological tolerance. Limits of cryptogams towards more mesic sites are, however, considered to be set by competitive ability (growth rates) in accordance with the competitive hierarchy theory. N availability is assumed to be the most important factor for differentiation of vascular plants along the nutrient gradient, while bryophytes are expected to respond to a complex of factors, including structural properties of the humus layer. Increasing N accumulation in the humus towards xeric sites may indicate oversaturation due to deposition of airborne NO3- or NH4+. Fine-scale paludification, mainly of a soligenous type, occurred in sloping terrain with shallow soil. The cryptogams apparently make up a competitive hierarchy also along the paludification gradient. No other coenoclines could be identified by analysis of 0.0625 m2 micro sample plots, most probably because the response of vegetation to micro-scale environmental gradients (probably most important: the variation in microtopography) not essentially different from the meso-scale gradients, and because the importance of random processes increase towards finer scales. Structuring processes are discussed with reference to the observed patterns. The lack of a closed bottom layer in almost all sample plots is considered a strong indication of high importance of fine-scale disturbance and density-independent mortality in the investigated system, while interspecific competition is of lower importance. The methodology in vegetation ecological studies is discussed with particular reference to monitoring. The potential of an integrated concept using permanent plots, parallel investigation of vegetation and environmental parameters, and gradient analysis, is stressed. Several suggestions for future studies, based on this integrated approach, are made.

Mapping marine biodiversity in the algae belt, Norway
The marine algae belt comprising kelp forests, seagrass meadows and rocky reefs with coralline red seaweeds is one of the most active primary-producing environments in the sea. It also harbors are great diversity of animals including sea squirts, ribbon worms, nick worms, serpulid worms, spionid worms and skeleton shrimps. The species of these groups occupy important ecological functions as herbivores, predators and filter-feeding organisms and can be sessile or agile as well as solitary or colonial. Many of these taxa include invasive species causing among others high economic damage in aquaculture and ship transportation due to biofouling. In this project, we conducted a field inventory and collect species of these taxa in Norway. Most of our records from this project (575 records) have been published in GBiF as part of the NHMO Invertebrate, DNA Bank Other invertebrate groups and DNA Bank Arthropod collections. However, 58 records were deposited in a different collection at NHMO as they do not belong to these three collections. By this dataset, these are publicly released separately to GBiF.

Invertebrate diversity and succession chronosequenced at proglacial sites.
This study aims to do a repeated survey along two proglacial chronosequences near Kongsfjorden, Svalbard. This study will revisit and sample the same sites as those studied by Hodkinson et al. (2004) in their work "invertebrate community assembly along proglacial chronosequences in the high Arctic". their study demonstrated that the succession was predictable, directional and deterministic closely linked to plant colonisation, soil development and species specific traits. Since the study was conducted in 2004 climate change has increased temperatures causing the glacier to further retreat. With temperatures in Svalbard increasing with approximately four degrees in the past century. The Arctic is particularly vulnerable to climate change due to a phenomenon known as Arctic amplification, whereby the region is warming up to four times faster than the global average. In addition to analysing community assembly and assessing explanatory abiotic/biotic factors, we're also evaluating potential climate-driven shift in colonisation patterns.

The purpose of the survey is to identify the presence and observed density of vulnerable species that may form habitats listed on the Norwegian Red List for Ecosystems and Habitat Types (Artsdatabanken, 2018), on OSPAR’s list of threatened and/or declining habitats (OSPAR 2008-06, revised in 2021), and among the proposed management-relevant habitat types for fisheries and aquaculture (Institute of Marine Research Report, 2024-16). At depths greater than 50 meters, the focus is mainly on corals, sponges, and sea pens. However, other red-listed and/or vulnerable species that live in close interaction with the three-dimensional habitats formed by the aforementioned groups will also be described when relevant. At depths shallower than 50 meters, the survey includes kelp forests, soft-bottom shoreline areas, coarse substrate bottoms, marine seagrass beds, exposed blue mussel beds, oysters, scallop populations, corals, sponges, sea pens, and any other red-listed shallow-water species. The investigation is based on the Institute of Marine Research’s proposed methodology for surveying vulnerable species and habitats in deep water (>50 meters depth) in connection with applications for marine aquaculture (Kutti and Husa 2021) or on the recommended methodology from the fishing and environmental directories (2022).

Vegetation occurrence and leaf traits of Salix polaris along a postglacial chronosequence at Midtre Lovenbreen
Glacier retreat in Svalbard exposes new terrain that undergoes ecological succession. Vegetation development was investigated along the postglacial chronosequence of Midtre Lovénbreen near Ny-Ålesund, building on sites first studied by Hodkinson et al. (2003) and revisited after ~25 years of accelerated warming. Vegetation cover, soil moisture, and leaf traits of Salix polaris (specific leaf area, SLA, and carbon-to-nitrogen ratio, C:N) were recorded across six forefield sites. The findings support successional dynamics described two decades earlier and emphasize the influence of ongoing climate warming on community assembly in the High Arctic.

Vascular plant presence/absence from lime-rich forest in selected sites categorized by the Ecosyst framework.
This dataset encompasses the results of an exhaustive survey focused on vascular plant biodiversity within the Drammensdalføret region, specifically targeting the predominantly north-facing southern slopes covering an elevation range of 81–389 meters above sea level. The study area is characterized by its varied terrain, from rolling to rugged, bisected by the deep Veia Gorge with the Veia river flowing from south to north. The northern parts of the area, lying below the marine limit, feature largely cultivated flat terrains. The geological foundation comprises sedimentary rocks from the Oslo field, with a generally thin overlying layer of soil deposits. The region's long history of land use, primarily for grazing and forestry, significantly marks its landscape. Our study adopted a meticulous sampling design in alignment with the EcoSyst/NiN methodology, aiming to analyze compositional patterns and ecodiversity distances across forests. To capture the ecological variance, particularly focusing on environmental gradients such as lime richness, drought risk, and the influence of spring water, we deployed 10 × 10 m plots along semi-random transects. These transects were strategically arranged to traverse the ecological spectrum with minimal bias, ensuring a representative sampling of the area's ecological diversity. The placement of transects and plots prioritized capturing ecological variances within predefined polygons, with 48 transects and 342 plots ultimately selected for detailed examination, as outlined in the study's appendices. The dataset is structured into three key components to provide a holistic view of the study's findings: Event Core Dataset: Documents each observational event, detailing the geographic and ecological context of the plots surveyed. Occurrence Extension Dataset: Contains records of individual plant species observed within the plots, offering insights into the area's floristic diversity. MeasurementOrFact Extension Dataset: Enriches the dataset with specific environmental measurements and facts related to each observational event, allowing for a deeper understanding of the conditions under which observations were made. This comprehensive survey of vascular plant biodiversity not only enhances our understanding of the ecological diversity within the Drammen valley but also contributes valuable data to the global biodiversity informatics infrastructure through GBIF. By documenting the rich biodiversity and the intricate ecological gradients of this region, the dataset supports further research in plant ecology, conservation planning, and the management of natural resources.

Macrozooplankton trawled at the Barents Sea Polar Front in May 2022
## Methods ### Study area This dataset is the result from sampling at 6 stations across the Polar Front in the western part of the Barents Sea. ### Time coverage The samples were collected between 19 May 2022 and 25 May 2022. ### Sampling 11 macrozooplankton samples were collected with a Tucker trawl (1 m2 opening and 1500 μm mesh size) and towed for 10 minutes at ca. 2 knots. The targeted depth at each station was determined from the sound scattering layer identified in the echogram from the vessel's echosounder. ### Sample analysis Relative abundance from the Tucker trawl samples were analyzed per station, and taxa were counted and dried at 60 C° in pre-weighted recipients for dry weight measurements. The obtained abundances were standardized and converted to catch per unit effort, expressed in milligrams per cubic meter.

Data on vascular plants was collected in 2009-2011 in Mabira Forest, Uganda as part of the MATRIX project in order to look at forest recovery from disturbance. Mabira Central Forest Reserve (hereon Mabira Forest) is close to Lake Victoria in Central Uganda. Mabira Forest is a semi-deciduous forest, considered secondary growth and highly influenced by human activities. About 95 per cent of the forest is of the Celtis-Chrysophyllummedium altitude semi-deciduous forest type; within this there are different sub-climax communities which have developed since the forest underwent phases of felling and heavy encroachment. Three ages of stand were surveyed to examine how quickly plants were recovering from disturbance. Transects of 10 m × 30 m were established in randomly-selected compartments in each of the three types. In order to cover a range of microhabitats, transects were arranged in ‘triplets’ of increasing distance upslope from forest streams, at 5 m, 65 m, and 125 m. For all other angiosperm sampling, transects were situated in the same locations (subject to 10 m GPS-derived relocation error) as the 5m and 125 m transects for the ferns. In total, 63 transects were sampled for ferns and 35 for angiosperms. In transects where angiosperms were sampled, trees of DBH (diameter at breast height) >10 cm were counted across the whole transect. Ground layer vegetation up to 2 m height was sampled by dividing the 10 × 30 m transect into 5 × 5 m plots and sampling six of those subplots, moving along the transect on alternate sides. All the species in these subplots were recorded, (including all woody plants large enough to identify and with stems < 10 cm DBH), and their percent cover estimated. Ferns were recorded by abundance of individuals, which was estimated in classes (<5, 6-15, 16-30, 31-50, 50-100, >100). Individuals which could not be identified were taken to Makerere University Herbarium for identification. We are grateful to the Ugandan National Forest Authority (NFA) for permitting access to work in Mabira.

Specimens from India at the NTNU University Museum in Trondheim
This dataset includes specimens originating from India in the natural history collections at the University Museum of the Norwegian University of Science and Technology (NTNU). Animals: The zoological collection includes 1 cnidarian, 122 molluscs (mostly marine), 24 birds, 4 mammals and three reptiles. These are all old specimens, presumably from the end of the 19th century or the first half of the 20th century, without collecting date. In addition, the collecting site is poorly documented, often restricted to “India” or “Indian Ocean”. There is no easy way to obtain more precise data. Data from Indian specimens in Trondheim are not previously available in the GBIF portal. Plants: The vascular plant collection has not been digitised, but random sampling suggests that it contains no specimens from India. The most interesting Indian material in Trondheim is found in the bryophyte collection, which houses the legacy of the botanist Ingebrigt Hagen (1852-1917). In the course of 2013 the bryophyte herbarium with its circa 30.000 specimens will be digitised. A random sample suggests that the number of specimens from India will be around 200. These are mostly from the Himalaya, and include relatively many type specimens (not labelled as such) which the Finnish botanist V.F. Brotherus (1849-1929) has worked on. These specimens have relatively complete collecting data. Moreover, the digitisation project in Trondheim includes the addition of the currently valid nomenclature. As an illustration of the data that become available after digitisation, an initial sample is included in this dataset.

It was further intended that the collections should form a core material for a series of publications on Nordic marine fauna named ‘Marine Invertebrates of Scandinavia (MIOS)’. Ten volumes were published, but the original idea of a series covering more than 40 systematic groups was never completed. The collected material was deposited in the invertebrate collections of the Natural History Museum of the University of Oslo. Parts of the material has not yet been registered. Parts has been registered but still not been digitised (status per 2018). It will be published in GBIF as occurrence files which will be linked to these datasets using the corresponding eventID. So far, occurrence data of several polychaete families have been published: https://ipt.gbif.no/resource?r=polychaeta

This study displays the occurrence and abundance of benthic macroinfauna communities within Kongsfjorden, Svalbard, comparing a deep-water monitoring station with a near-shore coastal site. The fieldwork was conducted in April 2026 at two primary locations: ST1, a near-shore shallow location created and utilized by the course AB-202 at UNIS near the Ny-Ålesund pier, and KB3, a long-term marine monitoring station located in the fjord's outer basin. Benthic samples were collected using a 0.1 m2 Van der Veen grab. At ST1, two successful samples were retrieved from depths of 50.9 m and 59.3 m. At KB3, a single successful sample was obtained from a depth of 345 m.The bulk sediment was collected into containers and sieved using 1 mm mesh-size to isolate macroinfauna from debris. Subsequent laboratory analysis involved the identification and enumeration of species using microscopy to determine community composition and abundance.

Visuelle undersøkelser - petroleumsvirksomhet
Her kan du se data fra visuelle undersøkelser av havbunnen fra petroleumsvirksomhet til havs. Dette er hovedsakelig data som er samlet inn i forbindelse med lovpålagte visuelle miljøundersøkelser. Hensikten med visuelle undersøkelser i forbindelse med petroleumsaktivitet er å kartlegge tilstedeværelse og omfang av arter og naturtyper som er på norsk rødliste (Artsdatabanken 2018) eller på OSPARs liste over truede og/eller minkende habitat (OSPAR, reference number: 2008).

Pelagic fish trawled at the Barents Sea Polar Front in May 2022
This dataset is the result of pelagic trawling at the Polar Front, in the western part of the Barents Sea between in May 2022. Five pelagic trawl samples were collected with a Harstad pelagic trawl, which has an effective height of 9-11 m and width of 10-12 m when towed at ca. 3 knots. The mesh size of the inner liner of the cod end was 10 mm. The pelagic trawl was towed at ca. 3 knots for 20-30 min and abundances were standardized by converting to catch per unit effort (expressed in kilograms per cubic meter).

Effects of vegetation clearing on vascular plants in power line clearings southeast Norway
Linear habitats, such as power-line clearings, have been thought to affect biodiversity negatively. However, during the last decade several studies have highlighted the potential value of power-line clearings as habitats for a number of taxonomic groups, like bees and butterflies. The vegetation below power-lines is continuously reset to earlier successional stages, which provides suitable habitats for several native plant species which hosts diverse assemblages of pollinating species. With proper management, power-line clearings could be important for conservation of species associated with open-canopy habitats. We conducted a large-scale field experiment, with 19 sites haphazardly distributed within the main power line grid in southeast Norway. All sites were placed below power lines in a boreal forest system consisting of varying proportions of the main tree species: Norway spruce Picea abies, Scots pine Pinus sylvestris and birch Betula spp. Sites were located between latitudes 59.33°–61.12°N and longitudes 08.95°–11.36°E at 48–536 m a.s.l., varying in width and age. Each site had been subjected to the same management regime with cutting of all woody vegetation every 5-10 years, without chemicals used, and had a stretch of at least 200 meters with substantial regrowth of trees before experiments were performed. At each site, we established three plots of approx. 30 x 60 m, at least 20 m apart. During late autumn 2012 (16 sites) and early spring 2013 (3 sites), treatments were randomly allocated to each of the plots within a site: 1) cut: woody vegetation was cut and left to decay in the plot, 2) cut-remove: woody vegetation was cut and removed, 3) Vegetation was uncut. We placed a systematic grid with nine plant-plots of 1m2 within each treatment plot, and visually quantified % abundance of all vascular plants the following seasons. The plant-plots were regularly spaced within a 10m × 10m subplot located in the centre of each treatment plot. Registrations were carried out in late June/early July in 2013, 2014 and 2015. If a species was present in a subplot, but had < 1% cover, it was recorded as 0.001%. The field data collections are funded by Statnett, and designed to study effects of vegetation clearing on biodiversity (i.e. vascular plants and insects) under power line clearings.

Equinor cold-water coral surveys on the Norwegian continental shelf
As part of regular environmental monitoring, Equinor performs cold-water coral surveys on the Norwegian continental shelf (NCS). Cold-water corals are key species in the marine environment that are known to form two important habitat types: coral reefs and coral gardens. On the NCS, the coral reefs are predominantly made up of the scleractinian coral Desmophyllum pertusum (formerly known as Lophelia pertusa), whereas the coral gardens consist of several soft coral species (gorgonians) grouped together. Both coral reefs and gardens are covered by Equinor’s surveys. The coral surveys are performed using visual ROV inspection according to the Handbook of Species and Habitats of Environmental Concern (offshorenorge.no). The surveyed coral locations are provided as georeferenced polygons that may be plotted in any GIS application. For each surveyed location, the corals are evaluated based on coverage and health. For coral reefs, the approximate living area (m2) and living coral coverage (%) are reported along with a corresponding health classification (poor, fair, good or excellent). For coral gardens, the number of specimens per 25 m2 is reported along with a health classification equivalent to that of coral reefs. Note that both reefs and gardens often are present at the same location.
