Population research on small rodents (Rodentia) and screws (Soridae) in Steinkjer Municipality – Norway; 2018 - 2019 based on systematic catches with ordinary mouse traps in traplines
The data in this sampling event resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 88 records.
2 extension data tables also exist. An extension record supplies extra information about a core record. The number of records in each extension data table is illustrated below.
This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.

|Bounding Coordinates||South West [64.013, 11.578], North East [64.013, 11.578]|
Cover the catches of all small Rodents and Screws
|Order||Rodentia (Rodents), Soridae (Screws)|
|Start Date / End Date||1996-01-01 / 2019-01-01|
Ordinary Norwegian RAPP mousetraps are put out in a line - 5 meters apart at spots selected to be a good place to catch mouse. Traps are baited with pieces of raw potatoe. The normal number of traps have been 100 in each transcept, but deviation from this occur. Traps are our for 2 nights - approximate 40 hours. Catches are picked up every morning.

|Funding||The main funding is by Nord university as this is part of a education/Class program. Processing the data is partly funded by The Norwegian Ministry of Climate and Environment.|
|Study Area Description||Transect 3 is a new cut area of lowland boreal - spruce dominated forest. Due to succession porocesses traps have been put out on different clearcuts in the vicinity to keep trapping at a grass/herb dominated secondary, young succsession stage. Trancect 4 was in an old, mature spruce forest near to transect 3 and with same vegetation type. Transect 5 is new for 2019 as the forest of the transect 4 was logged the previous winter.|
|Design Description||Given in "Description"|
The personnel involved in the project:
|Study Extent||The collection of data is done once a year in september. Purpose is partly to teach students the methods and ability to identify mouse species, but also as a part of a long term population cycle study for the region.|
|Quality Control||The species and sex is controlled by students and the teachers in cooperation.|
Method step description:
- Rodents and screws are protected species in Norway and trapping in nature is only permitted for scientific and/or pedagogical purposes. Permits are given for this research by The Norwegian Ministry of Climate and Environment. The Method is in itself simple and decribed earlier.
|Collection Name||Rodents and Screws in Steinkjer Municipality - Norway|
