    • An integrated population model for a long-lived ungulate: more efficient data use with Bayesian methods 

      Lee, Aline Magdalena; Bjørkvoll, Eirin Marie; Hansen, Brage Bremset; Albon, Steve D.; Stien, Audun; Sæther, Bernt-Erik; Engen, Steinar; Veiberg, Vebjørn; Loe, Leif Egil; Grøtan, Vidar (Journal article, 2015)
      We develop an integrated population model for Svalbard reindeer Rangifer tarandus platyrhynchus, and demonstrate how this type of model can be used to extract more information from the data and separate different sources ...

    • 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 ...

    • Demographic buffering of life histories? Implications of the choice of measurement scale 

      Bjørkvoll, Eirin Marie; Lee, Aline Magdalena; Grøtan, Vidar; Sæther, Bernt-Erik; Stien, Audun; Engen, Steinar; Albon, Steve D.; Loe, Leif Egil; Hansen, Brage Bremset (Journal article; Peer reviewed, 2016)
      Life-history theory predicts that the vital rates that influence population growth the most should be buffered against environmental fluctuations due to selection for reduced variation. However, it remains unclear whether ...

    • Genetic variability and structure of the water vole Arvicola amphibius across four metapopulations in northern Norway 

      Melis, Claudia; Borg, Åsa Alexandra; Jensen, Henrik; Bjørkvoll, Eirin Marie; Ringsby, Thor Harald; Sæther, Bernt-Erik (Journal article; Peer reviewed, 2013)
      Water vole Arvicola amphibius populations have recently experienced severe decline in several European countries as a consequence of both reduction in suitable habitat and the establishment of the alien predator American ...

    • Life-history variation and stochastic population dynamics in vertebrates 

      Bjørkvoll, Eirin Marie (Doktoravhandlinger ved NTNU, 1503-8181; 2014:177, Doctoral thesis, 2014)
      Temporal fluctuations in populations are influenced by a large number of factors, including density effects, dispersal, interspecific interactions, and a number of environmental variables. Within populations, individuals ...
