(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-08-16)
      The biodiversity working group of the Arctic Council has developed pan-Arctic biodiversity monitoring plans to improve our ability to detect, understand and report on long-term change in Arctic biodiversity. The Arctic fox (Vulpes lagopus) was identified as a target of future monitoring because of its circumpolar distribution, ecological importance and reliance on Arctic ecosystems. We provide ...

    • Homage to Hersteinsson and Macdonald: climate warming and resource subsidies cause red fox range expansion and Arctic fox decline 

      Elmhagen, Bodil; Berteaux, Dominique; Burgess, Robert. M.; Ehrich, Dorothee; Gallant, Daniel; Henttonen, Heikki; Ims, Rolf Anker; Killengreen, Siw Turid; Niemimaa, Jukka; Norén, Karin; Ollila, Tuomo; Rodnikova, Anna Y.; Sokolov, Aleksandr A.; Sokolova, Natasha A.; Stickney, Alice A.; Angerbjörn, Anders (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-08-16)
      Climate change can have a marked effect on the distribution and abundance of some species, as well as their interspecific interactions. In 1992, before ecological effects of anthropogenic climate change had developed into a topical research field, Hersteinsson and Macdonald published a seminal paper hypothesizing that the northern distribution limit of the red fox (Vulpes vulpes) is determined ...

    • Snowmobile impact on diurnal behaviour in the Arctic fox 

      Fuglei, Eva; Ehrich, Dorothee; Killengreen, Siw Turid; Rodnikova, Anna Y.; Sokolov, Aleksandr A.; Pedersen, Åshild Ønvik (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-08-16)
      As tourism increases globally, studies have documented impacts on wildlife from anthropogenic disturbances. In this observational experiment we aimed to investigate if snowmobile traffic affected the diurnal activity of Arctic fox in High Arctic Svalbard. We conducted the study in two areas in Svalbard, one control area with low snowmobile traffic and one experimental area with high snowmobile ...

    • Vole abundance and reindeer carcasses determine breeding activity of Arctic foxes in low Arctic Yamal, Russia 

      Ehrich, Dorothee; Cerezo, Maite; Rodnikova, Anna Y.; Sokolova, Natalya A.; Fuglei, Eva; Shtro, Victor; Sokolov, Aleksandr A. (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-09-16)
      High latitude ecosystems are at present changing rapidly under the influence of climate warming, and specialized Arctic species at the southern margin of the Arctic may be particularly affected. The Arctic fox (Vulpes lagopus), a small mammalian predator endemic to northern tundra areas, is able to exploit different resources in the context of varying tundra ecosystems. Although generally widespread, ...
