Changing Arctic snow cover: A review of recent developments and assessment of future needs for observations, modelling, and impacts
Bokhorst, Stef; Pedersen, Stine Højlund; Brucker, Ludovic; Anisimov, Oleg; Bjerke, Jarle W.; Brown, Ross D.; Ehrich, Dorothee (Journal article, 2016)Snow is a critically important and rapidly changing feature of the Arctic. However, snow-cover and snowpack conditions change through time pose challenges for measuring and prediction of snow. Plausible scenarios of ... -

Effects of resource availability and interspecific interactions on Arctic and red foxes' winter use of ungulate carrion in the Fennoscandian low-Arctic tundra
Lacombe, Simon; Ims, Rolf Anker; Yoccoz, Nigel Gilles; Kleiven, Eivind Flittie; Antunes Lopes Da Silva Nicolau, Pedro Guilherme; Ehrich, Dorothee (Peer reviewed; Journal article, 2024)In the Arctic tundra, predators face recurrent periods of food scarcity and often turnto ungulate carcasses as an alternative food source. As important and localized re-source patches, carrion promotes co-occurrence of ... -

Local land use associated with socio-economic development in six arctic regions
Ehrich, Dorothee; Thuestad, Alma Elizabeth; Tømmervik, Hans; Fauchald, Per; Hausner, Vera Helene (Journal article; Peer reviewed, 2018)The socioeconomic causes of land use change are complex.
