    • Interactions between demography and environmental effects are important determinants of population dynamics 

      Gamelon, Marlène; Grøtan, Vidar; Nilsson, Anna L. K.; Engen, Steinar; Hurrell, James W.; Jerstad, Kurt; Phillips, Adam S.; Røstad, Ole Wiggo; Slagsvold, Tore; Walseng, Bjørn; Stenseth, Nils Christian; Sæther, Bernt-Erik (Journal article; Peer reviewed, 2017)
      Climate change will affect the population dynamics of many species, yet the consequences for the long-term persistence of populations are poorly understood. A major reason for this is that density-dependent feedback effects ...

    • 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 ...
