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...

Spring 2023
The spatial distributions of animals have fascinated scientists for centuries. Understanding where animals go and why helps ecologists conserve their populations. Technological advances during the 21st century have allowed scientists to record the spatial location of animals over time, motivating...

Seasonal habitat use, habitat selection, and migratory behaviours of Stone’s sheep (Ovis dalli stonei) in northern British Columbia, Canada
DownloadFall 2021
Habitats and migration corridors used by wildlife have become increasingly modified by anthropogenic disturbances, and in many cases have resulted in population declines and local extirpations. To conserve ungulate populations, management strategies often focus on identifying and mitigating...

Space and habitat use of polar bears (Ursus maritimus) in Davis Strait in relation to sea ice conditions and harp seals (Pagophilus groenlandicus)
DownloadFall 2022
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,...

Using wildlife occurrence data to test permeability estimates and ecological indices used in urban planning
DownloadSpring 2023
Increasing urban development degrades ecosystems partly by diminishing natural area connectivity and quality, ultimately reducing and homogenizing urban biodiversity. To support biodiversity, ecological planners in Edmonton, Alberta (hereafter the City) have implemented tools to incorporate...
