• A battle of the mountains: Intraguild competition between arctic fox Vulpes lagopus and red fox Vulpes vulpes 

      Grevskott, Ragnhild Thorseth (Master thesis, 2019)
      Fjellreven (Vulpes lagopus) er en truet art i Fennoskandia. Konkurranse med rødreven (Vulpes vulpes) er regnet som en av hovedtruslene for fjellrevens utbredelse. Flere bevaringstiltak har blitt satt i gang for å redde ...
    • Drivers of change in meso-carnivore distributions in a northern ecosystem 

      Rød-Eriksen, Lars (Doctoral theses at NTNU;2020:182, Doctoral thesis, 2020)
      Species have been subject to major perturbations in recent times, such as over-harvest, habitat loss and climate change, affecting their distribution and abundance. Alpine and arctic tundra ecosystems are particularly ...
    • Fitness and fur colouration: Testing the camouflage and thermoregulation hypotheses in an Arctic mammal 

      Di Bernardi, Cecilia; Thierry, Anne-Mathilde; Eide, Nina Elisabeth; Bowler, Diana Elizabeth; Rød-Eriksen, Lars; Blumentrath, Stefan; Tietgen, Lukas; Sandercock, Brett; Flagstad, Øystein; Landa, Arild (Peer reviewed; Journal article, 2021)
      1. Selection for crypsis has been recognized as an important ecological driver of animal colouration, whereas the relative importance of thermoregulation is more contentious with mixed empirical support. A potential thermal ...
    • Highways associated with expansion of boreal scavengers into the alpine tundra of Fennoscandia 

      Rød-Eriksen, Lars; Skrutvold, Johanna; Herfindal, Ivar; Jensen, Henrik; Eide, Nina Elisabeth (Peer reviewed; Journal article, 2020)
      1. Habitat fragmentation may affect species distributions through, for example, altered resource availability and shifts in species interactions. Fragmentation by roads has had negative impacts on Fennoscandian alpine ...
    • Predator co-occurrence in alpine and Arctic tundra in relation to fluctuating prey 

      Rød-Eriksen, Lars; Killengreen, Siw Turid; Ehrich, Dorothee; Ims, Rolf Anker; Herfindal, Ivar; Landa, Arild; Eide, Nina Elisabeth (Peer reviewed; Journal article, 2022)
      1. Large carnivores influence ecosystem dynamics in multiple ways, for example, by suppressing meso-carnivores and providing carrions for smaller scavengers. Loss of large carnivores is suggested to cause meso-carnivore ...
    • Scavenger community structure along an environmental gradient from boreal forest to alpine tundra in Scandinavia 

      Gomo, Gjermund; Rød-Eriksen, Lars; Andreassen, Harry Peter; Mattisson, Jenny; Odden, Morten; Devineau, Olivier; Eide, Nina Elisabeth (Journal article; Peer reviewed, 2020)
      Scavengers can have strong impacts on food webs, and awareness of their role in ecosystems has increased during the last decades. In our study, we used baited camera traps to quantify the structure of the winter scavenger ...
    • Subclinical thiamine deficiency results in failed reproduction in Arctic foxes 

      Jackson, Craig Ryan; Furnes, Marianne Waldum; Rød-Eriksen, Lars; Yap, Kang Nian; Davey, Marie Louise; Fossøy, Frode; Flagstad, Øystein; Eide, Nina Elisabeth; Ulvund, Kristine R. (Peer reviewed; Journal article, 2024)
      Thiamine deficiency can result in life-threatening physiological and neurological complications. While a thiamine-deficient diet may result in the onset of such symptoms, the presence of thiaminase – an enzyme that breaks ...
