Migratory species may shift established spatiotemporal patterns in response to anthropogenic impacts, so understanding the energetic consequences of behavioural plasticity may provide insight into how effectively migratory species respond to climate change. I used satellite telemetry to examine...

This dissertation examines a series of case studies in the politics and semiotics of animal welfare, Indigeneity, and sovereignty in the Canadian Eastern Arctic from 1950 to 2017. Arctic animals such as seals, sled dogs, wolves, and polar bears often become the focus of Canadian animal welfare...

Energetics are a key driver of animal decision-making, as survival depends on the balance between foraging benefits and movement costs. However, this fundamental perspective is often missing from habitat selection studies, which mainly describe correlations between observed space use and...

Migration is a behavioral response to temporal variation in resources. While migration phenology is often predictable, phenology is expected to shift as climate change alters seasonal resource availability. We used data from satellite-linked telemetry collars on adult female polar bears (Ursus...

Extensive declines in sea ice extent and thickness are occurring within the Arctic and are projected to continue in the future due to amplified polar warming. As a result, community composition and structure are changing within Arctic ecosystems. Animal diets are influenced by accessibility and...

Polar bear conservation faces significant challenges under Arctic warming, especially with respect to habitat loss and the resulting impacts on their seasonal energetic uptake and maintenance. Polar bears rely on sea ice for hunting, mating, denning, and rearing of offspring, and the availability...

Patterns of space use and habitat selection by polar bears (Ursus maritimus) vary among subpopulations where they have been studied. The Davis Strait subpopulation is one of the least researched polar bear subpopulations and their spatial ecology is largely unknown. As an obligate carnivore,...
