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 ... -
Territory location and quality, together with climate, affect the timing of breeding in the whitethroated dipper
Nilsson, Anna; Slagsvold, Tore; Røstad, Ole Wiggo; Knudsen, E.; Jerstad, Kurt; Cadahia, Luis; Reitan, Trond; Helberg, Morten; Walseng, Bjørn; Stenseth, Nils Christian (Journal article; Peer reviewed, 2019)Recent climate change has led to advanced spring phenology in many temperate regions. The phenological response to variation in the local environment, such as the habitat characteristics of the territories birds occupy, ... -
The potential influence of Atlantic salmon Salmo salar and brown trout Salmo trutta on density and breeding of the white-throated dipper Cinclus cinclus
Nilsson, Anna; L'Abee-Lund, Jan Henning; Vøllestad, Leif Asbjørn; Jerstad, Kurt; Larsen, Bjørn Mejdell; Røstad, Ole Wiggo; Saltveit, Svein Jakob; Skaugen, Thomas; Stenseth, Nils Christian; Walseng, Bjørn (Journal article; Peer reviewed, 2018)Interactions between birds and fish are often overlooked in aquatic ecosystems.
