Enregistrements de données
Les données de cette ressource données d'échantillonnage ont été publiées sous forme dune Archive Darwin Core (Darwin Core Archive ou DwC-A), le format standard pour partager des données de biodiversité en tant quensemble dun ou plusieurs tableurs de données. Le tableur de données du cœur de standard (core) contient 131 enregistrements.
Cet IPT archive les données et sert donc de dépôt de données. Les données et métadonnées de la ressource sont disponibles pour téléchargement dans la section téléchargements. Le tableau des versions liste les autres versions de chaque ressource rendues disponibles de façon publique et permet de tracer les modifications apportées à la ressource au fil du temps.

Méthodes déchantillonnage
Vegetation documentation through quadrat method, plant sample collected every 5 plots.
| Etendue de létude | This study took place between August 11 2026 to August 15 2026 on Storholmen. |
|---|---|
| Contrôle qualité | Same size quadrats, standardized procedure. |
Description des étapes de la méthode:
- Finding the plot: Use the handheld GPS device to find the coordinates on the grid that Maarten has already determined for this year’s study. Record quadrat # and coordinates. Use marker flags and place them in the center of each pair of coordinates. Then, obtain a 50x50 cm quadrat and align it so that the flag is in the middle of the quadrat. Do this for each marker flag. Slope Angle: Open the compass with the mirror pointing towards you and the mirror is pointed sideways or vertical. Hold the compass at eye level, with the adjustable ring pointing east towards you and align the compass to eye height of another student further away. At this point the northern direction should point perpendicular from the line of sight. Then the clinometer arrow will point at the angle of the surface. Slope Aspect: Stand with your back towards the slope (facing down the slope). Align compass needle with north-poiting arrow. Read the direction/degrees at the marker point. Elevation: Record from GPS device. Goose feces cover (frequency method x/16, %): Determining the % cover of goose feces involves noting if feces is present inside each full square in each quadrat. Go square by square inside the quadrat noting if feces is present or not, then tally the total number of squares out of 16 that contain feces to determine the % cover in the quadrat. Photograph: Take a photo of the quadrat from above Label photo clearly Note that this step has been complete in the data table NDVI: This device will capture the health and lushness of the vegetation. A field assistant or professor will use the device with the help of a student. Recording plants in the quadrant: Identify every plant present to species level (if able) for vascular plants, and to group/family for non-vascular plants (ex. mosses, lichens, liverwort, etc.) Record in data table. Plant species cover (frequency method x/16, %): Determining the % cover involves noting the species present inside each full square in each quadrat (similar to goose feces method). Start with one species and go square by square noting if it is present or not. Then tally the total number of squares out of 16 that contain that species to determine the % cover in the quadrat. Move on to the next species, and the next, etc using the same technique until every species has been accounted for. (TAKE PHOTOS OF SHEET WHEN FILLED OUT, & ALWAYS NOTE QUADRAT #) Sampling/collecting the leaves: Obtain 10 fully expanded, healthy, green, mature leaves that weren’t grazed on from S. polaris and S. cespitosa in plots with identifiers ending in zero or five (e.g., plot numbered 5, 10, 15, and so forth). To minimize contamination, tweezers or latex gloves are used to extract the leaves. In quadrats that contained sparse vegetation or were completely bare, leaf samples can be obtained from nearby areas in the same plot. If a plot ID ending in zero or five is in a place beyond reach (e.g., in the water), another plot can be chosen haphazardly for sampling. The leaves should be placed in a labelled (Quadrat and species) plastic/paper bag and transported to the laboratory for further processing and analysing.
