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 ... -
Caught in the mesh : roads and their network-scale impediment to animal movement
Bischof, Richard; Steyaert, Sam; Kindberg, Jonas (Journal article; Peer reviewed, 2017)Roads have a pervasive multi-faceted influence on ecosystems, including pronounced impacts on wildlife movements. In recognition of the scale-transcending impacts of transportation infrastructure, ecologists have been ... -
Determinants of lifetime reproduction in female brown bears: early body mass, longevity, and hunting regulations
Zedrosser, Andreas; Pelletier, Fanie; Bischof, Richard; Festa-Bianchet, Marco; Swenson, Jon (Journal article; Peer reviewed, 2013)In iteroparous mammals, conditions experienced early in life may have long‐lasting effects on lifetime reproductive success. Human‐induced mortality is also an important demographic factor in many populations of large ... -
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 ... -
The interplay between hunting rate, hunting selectivity, and reproductive strategies shapes population dynamics of a large carnivore
Van de Walle, Joanie; Pelletier, Fanie; Zedrosser, Andreas; Swenson, Jon; Jenouvrier, Stéphanie; Bischof, Richard (Peer reviewed; Journal article, 2021)Harvest, through its intensity and regulation, often results in selection on female reproductive traits. Changes in female traits can have demographic consequences, as they are fundamental in shaping population dynamics. ... -
Sociodemographic factors modulate the spatial response of brown bears to vacancies created by hunting
Frank, Shane C.; Leclerc, Martin; Pelletier, Fanie; Rosell, Frank; Swenson, Jon; Bischof, Richard; Kindberg, Jonas; Eiken, Hans Geir; Hagen, Snorre; Zedrosser, Andreas (Journal article; Peer reviewed, 2017)1. There is a growing recognition of the importance of indirect effects from hunting on wildlife populations, e.g. social and behavioural changes due to harvest, which occur after the initial offtake. Nonetheless, little ...
