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 Nature Communications.

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 important information about the animas without affecting them at all. However, novel methods also provide novel challenges. Up until now, researchers would have to look through hundreds of thousands of...

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 huge grazing pressure on the food-plants. Despite their importance much are still unknown about small rodents and their food-web interactions.

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 remote-sensing based maps.

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 mechanism is likely to promote diversity in our contemporary grasslands. The idea arised in the tundra grasslands of Varanger Peninsula during monitoring for COAT.

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 belowground compartment are poorly known.

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 scientific hypotheses to be tested more frequently, speeding up scientific advancement, and are relevant to managers because the time scale can be influenced by decision-making. This approach was used by...

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 impact of red fox culling on a threatened ptarmigan species.

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 and suggests that the forest may fail to recover in the most heavily affected areas.
