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, 2018)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 (Journal article; Peer reviewed, 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 ... -
A guide for studying among-individual behavioral variation from movement data in the wild
Hertel, Anne Gabriela; Niemelä, Petri T.; Dingemanse, Niels J.; Mueller, Thomas (Peer reviewed; Journal article, 2020)Animal tracking and biologging devices record large amounts of data on individual movement behaviors in natural environments. In these data, movement ecologists often view unexplained variation around the mean as "noise"when ... -
Heritability of head size in a hunted large carnivore, the brown bear (Ursus arctos)
Rivrud, Inger Maren; Frank, Shane C.; 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 ... -
Social environment shapes female settlement decisions in a solitary carnivore
Hansen, Jennifer Eve; Hertel, Anne Gabriela; Frank, Shane C.; Kindberg, Jonas; Zedrosser, Andreas (Peer reviewed; Journal article, 2021)How and where a female selects an area to settle and breed is of central importance in dispersal and population ecology as it governs range expansion and gene flow. Social structure and organization have been shown to ... -
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 ...
