Energy Selection Functions: Modelling the Energetic Drivers of Animal Movement and Habitat Use
DownloadSpring 2021
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...

Monitoring Ecosystem Dynamics in the Beaufort Sea using Stable Isotopes in Polar Bears (Ursus maritimus) and Ringed Seals (Pusa hispida)
DownloadSpring 2019
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 bears (Ursus maritimus) are an apex predator of the Arctic marine food web and vulnerable to changes in sea ice because various aspects of their existence depend on this dynamic platform. Arctic sea ice extent and thickness have declined, and been particularly low since the first record...
