Does despotic behavior or food search explain the occurrence of problem brown bears in Europe?
Elfström, Marcus; Zedrosser, Andreas; Jerina, Klemen; Støen, Ole-Gunnar; Kindberg, Jonas; Budic, Lara; Jonozovic, Marko; Swenson, Jon (Journal article; Peer reviewed, 2014)Bears foraging near human developments are often presumed to be responding to food shortage, but this explanation ignores social factors, in particular despotism in bears. We analyzed the age distribution and body condition ... -
Ecological implications from spatial patterns in human-caused brown bear mortality

Faecal spectroscopy: a practical tool to assess diet quality in an opportunistic omnivore
Steyaert, Sam; Hütter, Franziska J.; Elfström, Marcus; Zedrosser, Andreas; Hackländer, Klaus; Le, Minh Hung; Windisch, Wilhelm M.; Swenson, Jon; Isaksson, Tomas (Journal article; Peer reviewed, 2012)Faecal indices of dietary quality can provide useful knowledge about the general ecology of a species, but only if the measurements are accurate and the results are interpreted with caution. In this article, we evaluated ... -
Gut retention time in captive brown bears Ursus arctos
Elfström, Marcus; Støen, Ole-Gunnar; Zedrosser, Andreas; Warrington, Ian; Swenson, Jon (Journal article; Peer reviewed, 2013)Knowing animals’ gut retention time (GRT) for important food items is critical when using non-invasive studies based on faecal remains, e.g. when analysing nutritive quality of food, or relating diet or behaviour to ...
