    • 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 ...

    • Temporal trend of mercury in relation to feeding habits and food availability in arctic foxes (Vulpes lagopus) from Svalbard, Norway 

      Hallanger, Ingeborg G.; Fuglei, Eva; Yoccoz, Nigel Gilles; Pedersen, Åshild Ønvik; König, Max; Routti, Heli Anna Irmeli (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-03-20)
      We investigated the temporal trend of mercury (Hg) in arctic foxes from Svalbard, Norway sampled in the period 1997–2014 (<i>n</i> = 109, from 11 trapping seasons). We used linear models to investigate the effect of trapping season, feeding habits (δ<sup>13</sup>C), food availability from marine and terrestrial ecosystems (reindeer carcasses and sea ice cover), sex, age and body condition on liver ...

    • Unique genetic features of canine adenovirus type 1 (CAdV-1) infecting red foxes (Vulpes vulpes) in northern Norway and arctic foxes (Vulpes lagopus) in Svalbard 

      Balboni, Andrea; Tryland, Morten; Mørk, Torill; Killengreen, Siw Turid; Fuglei, Eva; Battilani, Mara (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-03-02)
      Canine adenovirus type 1 (CAdV-1) is the aetiological agent of infectious canine hepatitis (ICH) in domestic dogs (<i>Canis familiaris</i>). In spite of the widespread use of vaccination, CAdV-1 continues to circulate in the dog population. Although a high number of serological screenings have indicated that CAdV-1 is widespread in fox species, little is known about the potential role of foxes as ...

    • 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, ...

    • Why are Svalbard Arctic foxes Brucella spp. seronegative? 

      Nymo, Ingebjørg Helena; Fuglei, Eva; Mørk, Torill; Breines, Eva Marie; Holmgren, Karin Elisabeth; Davidson, Rebecca K.; Tryland, Morten (Journal article; Tidsskriftartikkel, 2022-07-06)
      Arctic foxes (Vulpes lagopus) are susceptible to smooth Brucella (s-Brucella) infection and may be exposed to such bacteria through the consumption of infected marine mammals, as implied by the finding of s-Brucella antibodies in polar bears (Ursus maritimus). Arctic foxes in Svalbard have not previously been investigated for s-Brucella antibodies, but such antibodies have been detected in Arctic ...
