• A human-induced landscape of fear influences foraging behavior of brown bears 

      Lodberg-Holm, Hanna Kavli; Gelink, Henriette Wathne; Hertel, Anne Gabriela; Swenson, Jon; Domevscik, Matej; Steyaert, Sam (Journal article; Peer reviewed, 2019)
      Animals adapt their foraging behavior to variations in food availability and predation risk. In Sweden, brown bears (Ursus arctos) depend on a nearly continuous intake of berries, especially bilberries (Vaccinium myrtillus) ...
    • Bears and berries: species-specific selective foraging on a patchily distributed food resource in a human-altered landscape 

      Hertel, Anne Gabriela; Steyaert, Sam; Zedrosser, Andreas; Mysterud, Atle; Lodberg-Holm, Hanna Kavli; Gelink, Henriette Wathne; Kindberg, Jonas; Swenson, Jon (Peer reviewed; Journal article, 2016)
      When animals are faced with extraordinary energyconsuming events, like hibernation, finding abundant, energy-rich food resources becomes particularly important. The profitability of food resources can vary spatially, ...
    • Berry production drives bottom – up effects on body mass and reproductive success in an omnivore 

      Hertel, Anne Gabriela; Bischof, Richard; Langval, Ola; Mysterud, Atle; Kindberg, Jonas; Swenson, Jon; Zedrosser, Andreas (Journal article; Peer reviewed, 2017)
      Obligate herbivores dominate studies of the eff ects of climate change on mammals, however there is limited empirical evidence for how changes in the abundance or quality of plant food aff ect mammalian omnivores. Omnivores ...
    • Endozoochory by brown bears stimulates germination in bilberry 

      Steyaert, Sam; Hertel, Anne Gabriela; Swenson, Jon (Peer reviewed; Journal article, 2019)
      The understory vegetation of the Eurasian boreal forest is dominated by several ericaceous species (e.g. bilberry Vaccinium myrtillus). These species invest large amounts of energy in their sexual reproduction by producing ...
    • Heritability of head size in a hunted large carnivore, the brown bear (Ursus arctos) 

      Rivrud, Inger Maren; Frank, Shane; Bischof, Richard; Mysterud, Atle; Steyaert, Sam; Hertel, Anne Gabriela; Hagen, Snorre; Eiken, Hans Geir; Swenson, Jon; Zedrosser, Andreas (Journal article; Peer reviewed, 2019)
      Wild animal populations experience selection pressures from both natural and anthropogenic sources. The availability of extensive pedigrees is increasing along with our ability to quantify the heritability and evolvability ...
    • Temporal effects of hunting on foraging behavior of an apex predator: Do bears forego foraging when risk is high? 

      Hertel, Anne Gabriela; Zedrosser, Andreas; Mysterud, Atle; Støen, Ole-Gunnar; Steyaert, Sam; Swenson, Jon (Journal article; Peer reviewed, 2016)
      Avoiding predators most often entails a food cost. For the Scandinavian brown bear (Ursus arctos), the hunting season coincides with the period of hyperphagia. Hunting mortality risk is not uniformly distributed throughout ...
