Fiskesamfunnet i Osensjøen, Trysil og Åmot kommuner Hedmark. Status i 2013 og endringer siden 1970-åra.
Sandlund, Odd Terje; Linløkken, Arne; Gjelland, Karl Øystein; Johnsen, Stein Ivar; Rognerud, Sigurd; Museth, Jon; Dokk, John Gunnar; Garmo, Øyvind Aaberg; Walseng, Bjørn (NINA rapport;1046, Research report, 2014)Målsetningen for undersøkelsene i Osensjøen i 2013 var å fastslå status for fiskebestandene mer enn 30 år etter åpningen av Osa kraftverk i 1981. Mer spesifikt skulle vi også vurdere mulige effekter av planlagte endringer ... -
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 ... -
