• Contrasting effects of summer and winter warming onbody mass explain population dynamics in a food-limitedArctic herbivore 

      Albon, Steve D.; Irvine, R. Justin; Halvorsen, Odd; Langvatn, Rolf; Loe, Leif Egil; Ropstad, Erik; Veiberg, Vebjørn; van der Wal, René; Bjørkvoll, Eirin Marie; Duff, Elizabeth I.; Hansen, Brage Bremset; Lee, Aline Magdalena; Tveraa, Torkild; Stien, Audun (Journal article; Peer reviewed, 2016)
      The cumulative effects of climate warming on herbivore vital rates and population dynamics are hard to predict, given that the expected effects differ between seasons. In the Arctic, warmer summers enhance plant growth ...
    • Modellering av tap av tamrein til rovvilt - en risikomodell 

      Herfindal, Ivar; Brøseth, Henrik; Kjørstad, Morten Andre; Linnell, John Durrus; Odden, John; Persson, Jens; Stien, Audun; Tveraa, Torkild; Ersson, L. (NINA rapport;819, Research report, 2012)
      I januar 2011 fikk NINA i oppdrag av Direktoratet for naturforvaltning (DN) å vurdere om tilgjengelige forskningsdata kunne brukes til modellering av risikobasert erstatning for tap av tamrein til rovvilt. Oppdraget ble ...
    • The neglected season: Warmer autumns counteract harsher winters and promote population growth in Arctic reindeer 

      Loe, Leif Egil; Liston, Glen E.; Pigeon, Gabriel; Barker, Kristin; Horvitz, Nir; Stien, Audun; Forchhammer, Mads C.; Getz, Wayne M.; Irvine, Robert Justin; Lee, Aline Magdalena; Movik, Lars K.; Mysterud, Atle; Pedersen, Åshild Ønvik; Reinking, Adele K.; Ropstad, Erik; Trondrud, Liv Monica; Tveraa, Torkild; Veiberg, Vebjørn; Hansen, Brage Bremset; Albon, Steve D. (Peer reviewed; Journal article, 2020)
      Arctic ungulates are experiencing the most rapid climate warming on Earth. While concerns have been raised that more frequent icing events may cause die-offs, and earlier springs may generate a trophic mismatch in phenology, ...
    • When things go wrong: intra-season dynamics of breeding failure in a seabird 

      Ponchon, Aurore; Grémillet, David J.H.; Christensen-Dalsgaard, Signe; Erikstad, Kjell E; Barrett, Robert T.; Reiertsen, Tone Kristin; McCoy, Karen D.; Tveraa, Torkild; Boulinier, Thierry (Journal article; Peer reviewed, 2014)
      During breeding, long-lived species face important time and energy constraints that can lead to breeding failure when food becomes scarce. Despite the potential implications of intra-season dynamics in breeding failure for ...
