New study states: Areas with mild winters have lower rodent population peaks

31. January 2025
Warmer and wetter winters are expected to hamper rodents access to food, resulting in dampened, irregular or lost rodent population cycles. A new study shows that across Fennoscandian tundra,...

New article states: Loss of plant biodiversity can reduce soil carbon sequestration in grasslands

7. November 2023
COAT is part of Nutrient Network, a worldwide network of research stations linked to grasslands. We have our "stations" on the Varanger peninsula and have contributed to a publication in...

Classifying images from wildlife cameras using Artificial Intelligence

18. October 2023
Camera traps have become a popular tool in nature science. An example of this is the novel camera trap method we have developed in COAT for monitoring of small mammals. This method provides...

Scientific paper: Monitoring small rodents with camera traps

25. January 2023
Small rodents are crucial to the functioning of the tundra food-web because of their spectacular population cycles which gives the predators waste amounts of food in the peak years and cause a...

Drone-based mapping of changed vegetation

8. December 2021
COAT researchers monitor vegetation disturbances by biotic and abiotic factors, such as herbivory and extreme winter weather. However, these are not typical vegetation classes included in...

Do the forbs miss the Mammoth?

21. September 2021
An international team led by a COAT -professor at UiT proposes a mechanism by which the large Pleistocene mammals were essential in promoting a very high floristic diversity, and that a similar...

Cascading effects of moth outbreaks on subarctic soil food webs

31. August 2021
Large-scale moth outbreaks have led to profound changes in plant communities from birch forests dominated by dwarf shrubs to grass-dominated systems. However, the indirect effects on the...

Understanding and predicting how climate change impacts Svalbard ptarmigan population dynamics

18. February 2021
Iterative near-term forecasting is a promising approach to better understand and manage rapidly changing ecosystems such as the Arctic. Forecasts generated on a short-term time scale allow...

It is important to consider food web interactions when assessing how well mesopredator culling programs work

27. November 2020
Management of endangered species by culling mesopredators is increasingly common. To what extent such programs work as intended, is less clear. In a new study, COAT researchers evaluated the...

New method: Chemical traits of single leaves using near‐infrared reflectance spectroscopy (NIRS)

26. October 2020
Measures of plant chemical traits are often achieved by merging several leaves, masking potential foliar variation within and among plant individuals. In a new study, COAT researchers developed a...

An uncertain future for the mountain birch forest

17. December 2018
Outbreaks by geometrid moths have caused extensive damage to mountain birch forest in northern Scandinavia during the last 15 years. A new study helps to explain why the damage has been so severe...
