Polar Bear (Ursus maritimus) Habitat, Space Use,and Movements in a Seasonal Sea Ice Ecoregion
DownloadFall 2015
Polar bears (Ursus maritimus) are sea ice habitat specialists and climate change has affected sea ice throughout this species’ circumpolar range. The annual phenological cycle of sea ice growth and decay is a strong influence on polar bear distribution and ecology. Study of the habitat selection,...

Postbreeding movement patterns and multiscale habitat use of adult wood frogs (Lithobates sylvaticus) at urban wetlands of Edmonton, Alberta.
DownloadSpring 2014
Many studies have focused on the effects of urbanization on amphibian species richness, abundance and diversity, but few studies have quantified the effect on amphibian movement behaviour or habitat use. At 11 urban wetlands in Edmonton, Alberta, I examined the postbreeding movement behaviour and...

Many sports biomechanics research studies follow a traditional task analysis concept that there is only one best possible movement pattern and thus focus on the examination of kinematics and kinetics of movement without considering the influence of constraints that are imposed on it. This study...

Spatial ecology of cougars (Puma concolor) in the Cypress Hills: Implications for human-cougar interactions and range expansion
DownloadFall 2013
Cougar (Puma concolor) range is expanding eastward in North America. Understanding how range expansion is occurring in a human-dominated landscape is needed to manage the social and ecological implications of a returning large carnivore. To address this, I used GPS-radio collars and...

Sustaining the Recovery of Lake Sturgeon (Acipenser fulvescens) in the North Saskatchewan River of Alberta
DownloadSpring 2016
Nearly all Lake Sturgeon (Acipenser fulvescens) populations across North America have experienced losses to historic abundances estimated to be > 99%. This species is especially vulnerable to overharvest, habitat degradation, river fragmentation from dams, and is slow to recover due to life...

Fall 2017
Camera traps are an increasingly popular tool for wildlife management. Studies that use detection rates as a simple index of relative abundance assume that movement is not density-dependent. More complex techniques such as spatially-explicit capture recapture models, occupancy models, or...

The Increasing Prevalence of Smaller Fish in Highly Exploited Fisheries: Concerns, Diagnosis and Management Solutions.
DownloadSpring 2010
A decline in the size of fish within a population is concerning. Large-sized fish are ecologically important and valued for social and economic reasons. Following widespread collapses from angling overharvest, the densities of Walleyes Sander vitreus in Alberta’s lakes increased rapidly with...
