Effects of large carnivores, hunter harvest, and weather on the mortality of moose calves in a partially migratory population
(Peer reviewed; Journal article, 2023)Survival of juvenile ungulates represents an important demographic parameter that influences population dynamics within ecosystems. In many ecological systems, the mortality of juvenile ungulates is influenced by various ... -
Extrinsic and intrinsic factors drive the timing of gestation and reproductive success of Scandinavian brown bears
(Peer reviewed; Journal article, 2022)Climate change is altering the reproductive phenology of many organisms, but the factors that influence the timing of gestation in ursids are still poorly understood. Higher temperatures in spring are already causing an ... -
Hibernation and plasma lipids in free-ranging brown bears-implications for diabetes
(Peer reviewed; Journal article, 2023)Brown bears (Ursus arctos) prepare for winter by overeating and increasing adipose stores, before hibernating for up to six months without eating, drinking, and with minimal movement. In spring, the bears exit the den ... -
Landscape of fear or landscape of food? Moose hunting triggers an antipredator response in brown bears
(Peer reviewed; Journal article, 2023)Hunters can affect the behavior of wildlife by inducing a landscape of fear, selecting individuals with specific traits, or altering resource availability across the landscape. Most research investigating the influence of ... -
Lead exposure in brown bears is linked to environmental levels and the distribution of moose kills
(Peer reviewed; Journal article, 2023)Lead (Pb) is heterogeneously distributed in the environment and multiple sources like Pb ammunition and fossil fuel combustion can increase the risk of exposure in wildlife. Brown bears (Ursus arctos) in Sweden have higher ... -
Of wolves and bears: Seasonal drivers of interference and exploitation competition between apex predators
(Peer reviewed; Journal article, 2021)Competition between apex predators can alter the strength of top-down forcing, yet we know little about the behavioral mechanisms that drive competition in multipredator ecosystems. Interactions between predators can be ... -

Phenology of brown bear breeding season and related geographical cues
(Peer reviewed; Journal article, 2020)Knowledge about breeding biology is often incomplete in species with complex reproductive strategies. The brown bear Ursus arctos is a polygamous seasonal breeder inhabiting a wide variety of habitats and environmental ... -
Translational implications of bradyarrhythmia in hibernating brown bears
(Peer reviewed; Journal article, 2023)The brown bear Ursus arctos undergoes exceptional physiological adaptions during annual hibernation that minimize energy consumption, including profound decrease in heart rate, cardiac output, and respiratory rate. These ... -
What does the fox say? Arctic fox vocalization and associated den behaviours
(Peer reviewed; Journal article, 2024)Foxes (Vulpes spp.) are small, solitary canids with relatively low social complex-ity compared to more gregarious canids, such as wolves and dogs. They are, therefore, expected to have a relatively simple ... -
Wolf habitat selection when sympatric or allopatric with brown bears in Scandinavia
(Peer reviewed; Journal article, 2020)Habitat selection of animals depends on factors such as food availability, landscape features, and intraand interspecific interactions. Individuals can show several behavioral responses to reduce competition for habitat, ...
