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.

The red fox trapping has started - follow the red foxes live!

7. November 2023 The red fox trapping season in Varanger for COAT’s arctic fox module has started again! So far we caught 2 red foxes this year, a young male and an adult female. Both were equipped with GPS collars and released to study their movement on the tundra. Join us with tracking them live here, or read the recent article about our work in Ságat (in Norwegian). See release-videos in Facebook or...

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...

Switch on a bright outdoor lamp and leave it overnight!

4. October 2023

Geometrid moths are insects with a holometabolic life cycle. This means that the larvae, which feed on the leaves of birch trees in summer, undergo a complete metamorphosis into adult moth during the autumn. The adult moths have just begun their flight period, and COAT researchers are on their track!

Field report from Svalbard

11. September 2023

This report from this year's COAT fieldwork in Svalbard deals with our monitoring of eastern voles and arctic foxes in Svalbard, mainly in the area around Isfjorden.

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.

Snow measurements in Varanger

20. January 2023 Why is it interesting for a researcher to dig in the snow in January? It's just snow there, isn't it? Yes, it is snow, but we want to know what type of snow, and whether there are hard crusts and ice on the ground. The snow conditions now in winter can determine whether we get a small rodent peak year next summer. And if it will be a small rodent year with a lot of Lemming, we know for...
