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.

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.

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.

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...

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.

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 new application of Near-infrared Reflectance Spectroscopy (NIRS) methodology that provides measures of carbon, nitrogen, phosphorus, and silicon from single, whole leaves down to the size of just 4 mm.

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.
