Rémy, Alice; Le Galliard, Jean-Francois; Odden, Morten; Andreassen, Harry Peter (Journal article; Peer reviewed, 2013)1. During the settlement stage of dispersal, the outcome of conflicts between residents and immigrants should depend on the social organization of resident populations as well as on individual traits of immigrants, such ... -
Demographic side effects of selective hunting in ungulates and carnivores
Milner, Jos M.; Nilsen, Erlend Birkeland; Andreassen, Harry Peter (Peer reviewed; Journal article, 2007)Selective harvesting regimes are often implemented because age and sex classes contribute differently to population dynamics and hunters show preferences associated with body size and trophy value. We reviewed the ... -

Prosjektet er delt i økologiske ... -
Environmental attitudes associated with large-scale cultural differences, not local environmental conflicts
Gangås, Kristin Evensen; Kaltenborn, Bjørn P.; Andreassen, Harry Peter (Journal article; Peer reviewed, 2014)Species and ecosystems are under constant pressure from a rapidly-growing human population. Human tolerance of carnivores, including the willingness to live in areas with these predators, is key to the success of large ... -
