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. ... -
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 ... -

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 ...
