• Behavioral buffering of extreme weather events in a high-Arctic herbivore 

      Loe, Leif Egil; Hansen, Brage Bremset; Stien, Audun; Albon, Steve D.; Bischof, Richard; Carlsson, Anja M.; Irvine, Justin; Meland, Morten; Rivrud, Inger Maren; Ropstad, Erik; Veiberg, Vebjørn; Mysterud, Atle (Journal article; Peer reviewed, 2016)
      As global warming advances, there is a growing concern about the impact of extreme weather events on ecosystems. In the Arctic, more frequent unseasonal warm spells and rain-on- snow events in winter cause changes in ...
    • Circadian rhythmicity persists through the Polar night and midnight sun in Svalbard reindeer 

      Arnold, Walter; Ruf, Thomas; Loe, Leif Egil; Irvine, R. Justin; Ropstad, Erik; Veiberg, Vebjørn; Albon, Steve D. (Journal article; Peer reviewed, 2018)
      Studies of locomotor activity in Svalbard reindeer reported the temporary absence of diel rhythms under Arctic photic conditions. However, using Lomb-Scargle periodogram analyses with high statistical power we found diel ...
    • Klimaeffektar på svalbardreinens kalvingstidspunkt 

      Veiberg, Vebjørn; Danielsen, Preben; Loe, Leif Egil; Stien, Audun; Peeters, Bart; Hansen, Brage Bremset; Irvine, R. Justine; Ropstad, Erik; Albon, Steve D.; Tveraa, Torkild; Varpe, Øystein (NINA Rapport;1311, Research report, 2017)
      Veiberg, V., Danielsen, P., Loe, L. E., Stien, A., Peeters, B., Hansen, B. B., Irvine, R. J., Ropstad, E., Albon, S. D., Tveraa, T. & Varpe, Ø. (2017) Klimaeffektar på svalbardreinens kalvingstidspunkt – NINA Rapport 1311. ...
    • Little impact of over-winter parasitism on a free-ranging ungulate in the high Arctic 

      Carlsson, Anja M.; Albon, Steve D.; Coulson, Stephen J.; Ropstad, Erik; Stien, Audun; Wilson, Kenneth; Loe, Leif Egil; Veiberg, Vebjørn; Irvine, Robert Justin (Journal article; Peer reviewed, 2018)
      1. Macroparasites have a central place in wildlife ecology because they have the potential to regulate host populations through effects on reproduction and/or survival. However, there remains a paucity of studies that have ...
    • More frequent extreme climate events stabilize reindeer population dynamics 

      Hansen, Brage B.; Gamelon, Marlène; Albon, Steve D.; Lee, Aline M.; Stien, Audun; Irvine, R. Justine; Sæther, Bernt-Erik; Loe, Leif E.; Ropstad, Erik; Veiberg, Vebjørn; Grøtan, Vidar (Journal article, 2019)
      treme climate events often cause population crashes but are difficult to account for in population-dynamic studies. Especially in long-lived animals, density dependence and demography may induce lagged impacts of ...
    • The influence of weather conditions during gestation on life histories in a wild Arctic ungulate 

      Douhard, Mathieu; Loe, Leif Egil; Stien, Audun; Bonenfant, Christophe; Irvine, R. Justin; Veiberg, Vebjørn; Ropstad, Erik; Albon, Steve D. (Journal article; Peer reviewed, 2016)
      The internal predictive adaptive response (internal PAR) hypothesis predicts that individuals born in poor conditions should start to reproduce earlier if they are likely to have reduced performance in later life. However, ...
