Hydrology influences breeding time in the white‑throated dipper
Nilsson, Anna; Skaugen, Thomas; Reitan, Trond; LAbée-Lund, Jan Henning; Gamelon, Marlène; Jerstad, Kurt; Røstad, Ole Wiggo; Slagsvold, Tore; Stenseth, Nils Christian; Vøllestad, Leif Asbjørn; Walseng, Bjørn (Peer reviewed; Journal article, 2020)Background: Earlier breeding is one of the strongest responses to global change in birds and is a key factor determining reproductive success. In most studies of climate effects, the focus has been on large-scale 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 ... -
Location is everything, but climate gets a share: analyzing small-scale environmental influences on breeding success in the white-throated dipper
Nilsson, Anna L.K.; Reitan, Trond; Skaugen, Thomas; L'Abee-Lund, Jan Henning; Gamelon, Marlène; Jerstad, Kurt; Røstad, Ole Wiggo; Slagsvold, Tore; Stenseth, Nils Christian; Vøllestad, L. Asbjørn; Walseng, Bjørn (Peer reviewed; Journal article, 2020)Ecological and evolutionary effects of environmental variation on wild populations are of particular interest in a changing world. Large-scale environmental indices are classically used as environmental explanatory variables ... -
The number of syllables per phrase in songs of Great Tits Parus major decreases with high levels of anthropogenic noise and at northern latitudes
Husby, Magne; Slagsvold, Tore (Peer reviewed; Journal article, 2023)Birds may sing to defend a territory and to attract a mate. However, despite many studies clear conclusions remain on how ecological conditions affect the song, such as physical obstacles that may reduce the sound transmission, ... -
Survival of Willow tits Poecile montanus: the significance of flock membership, social rank and body size
Hogstad, Olav; Slagsvold, Tore (Journal article; Peer reviewed, 2018)The Willow Tit Poecile montanus is highly sedentary and breeding pairs remain in their exclusive areas throughout the year. During the winter, these areas are defended by small, non-kin flocks, formed as the roaming yearlings ...
