• Accounting for interspecific competition and age structure in demographic analyses of density dependence improves predictions of fluctuations in population size 

      Gamelon, Marlène; Vriend, Stefan; Engen, Steinar; Adriaensen, Frank; Dhondt, A.A.; Evans, Simon R.; Matthysen, Erik; Sheldon, Ben C.; Sæther, Bernt-Erik (Peer reviewed; Journal article, 2019)
      Understanding species coexistence has long been a major goal of ecology. Coexistence theory for two competing species posits that intraspecific density dependence should be stronger than interspecific density dependence. ...
    • Does multiple paternity explain phenotypic variation among offspring in wild boar? 

      Gamelon, Marlène; Gayet, Thibault; Baubet, Eric; Devillard, Sébastien; Say, Ludovic; Brandt, Serge; Pelabon, Christophe; Sæther, Bernt-Erik (Journal article; Peer reviewed, 2018)
      During pregnancy, littermates compete to extract maternal resources from the placenta. Unequal extraction of resources leads to developmental differences among offspring and thus within-litter variation in offspring mass. ...
    • Environmental drivers of varying selective optima in a small passerine: A multivariate, multiepisodic approach 

      Gamelon, Marlène; Tufto, Jarle; Nilsson, Anna; Jerstad, Kurt; Røstad, Ole Wiggo; Stenseth, Nils Christian; Sæther, Bernt-Erik (Journal article; Peer reviewed, 2018)
      In changing environments, phenotypic traits are shaped by numerous agents of selection. The optimal phenotypic value maximizing the fitness of an individual thus varies through time and space with various environmental ...
    • 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 Bremset; Gamelon, Marlène; Albon, Steve D.; Lee, Aline Magdalena; Stien, Audun; Irvine, Robert Justin; Sæther, Bernt-Erik; Loe, Leif Egil; Ropstad, Erik; Veiberg, Vebjørn; Grøtan, Vidar (Journal article; Peer reviewed, 2019)
      Extreme 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 ...
    • Spatial variation in senescence rates in a bird metapopulation 

      Holand, Håkon; Kvalnes, Thomas; Gamelon, Marlène; Tufto, Jarle; Jensen, Henrik; Pärn, Henrik; Ringsby, Thor Harald; Sæther, Bernt-Erik (Journal article, 2016)
      Investigating factors which affect the decline in survival with age, i.e. actuarial senescence, is important in order to understand how demographic rates vary in wild populations. Although the evidence for the occurrence ...
