The 6^th International arctic fox conference was arranged by the Norwegian Polar Institute in Longyearbyen 26-29 August. The conference was held at the University Centre in Svalbard and had in total 69 participants, of which 24 were online, from 14 countries.

Long-term monitoring represents a baseline approach for climate-ecological studies. Analyses and modeling of such monitoring data provide opportunities to generate explanatory predictions, used to test ecological theories, but also anticipatory predictions, suited to inform future management and policy decisions.

7. September 2022 This year's counting trip has been completed and many reindeer were counted on the isolated peninsulas on the west coast of Svalbard. These localities form one of the core areas for monitoring Svalbard reindeer. Both the population on Brøggerhalvøya and on the islands in Forlandssundet – Sarsøyra and Kaffiøyra – were large this year with consistently good calf production at all monitoring...

30. August 2022 COAT has modeled the population fluctuations of willow ptarmigan in Finnmark and looked at what influences changes in the population. The modeling is the result of a collaboration between COAT and several stakeholders, including the landowner Finnmarkseiendommen (FeFo).Now we have the results of this year’s FeFo assessment (i.e. line-transect surveys) to compare with our predictions which was...

Despite moderate abundances of rodents (an increase phase year) 12 arctic fox litters and 76 pups have been registered on Varanger Peninsula so far this summer.

Members of COAT Varanger’s ptarmigan module has recently deployed the sound stations for this year’s monitoring in the study area just above Bergebydalen in Nesseby municipality. This work started back in 2017, and this is therefore the 6^th years of monitoring the two arctic ptarmigan species by use of bioacoustics.

29. April 2022

COAT have in collaboration with Rovfuglgruppa I Vest-Finnmark, for the fourth consecutive year, checked how many gyrfalcons, golden eagles and ravens that are attempting to breed on the Varanger peninsula.

19. April 2022 We have started a large carcass-project in Svalbard and the first pictures is already collected. It will be interesting to see how the predators behave. The project is a collaboration between Norwegian Polar Institute, COAT and Nord Universitet. To read more about this study see Norwegian Polarinstitue's article presenting the study (in Norwegian). The same study has been carried out by COAT...

You may have heard about our gps-tracking project of red foxes on Varanger Peninsula. You can now participate by exploring the latest positions on this interactive and automatically updated map.

9. February 2022 SUSTAIN was a nationally coordinated research project funded by the Research Council of Norway during 2015-2021. The project included three geographic nods (research groups): Centre for Ecological and Evolutionary Synthesis (CEES) in Oslo, Centre for Biodiversity Dynamics (CBD) in Trondheim and COAT in Tromsø. A SUSTAIN special issue of the journal Climate Research has now been published.
