Individual and Seasonal Variation in Grizzly Bear Selection for a Railway and other Linear Features in Banff National Park, Canada
DownloadFall 2016
Mortality caused by collisions with trains affects numerous species globally and has increased recently to threaten the grizzly bear (Ursus arctos) population protected in Banff and Yoho National Parks, Canada. Although train collisions are the ultimate cause of mortality, the more proximate...

Mitigating the Effects of Human Activity on Grizzly Bears (Ursus arctos) in Southwestern Alberta.
DownloadSpring 2015
Anthropogenic habitat loss and alteration, as well as human-caused mortalities associated with increasing access, threaten grizzly bear populations across much of their North American range. This research investigates strategies for mitigating the negative effects of human activities on grizzly...

Urbanization is viewed as a major threat to global biodiversity because of its role in the loss and fragmentation of low-lying, productive habitats associated with coastal plains and river valleys. My study examines the effects of urbanization on the movements and distribution of songbirds in...

Occupancy and Impacts of the Northern Crayfish (Faxonius virilis) in Tributaries of the North Saskatchewan River Basin
DownloadFall 2021
Invasive species are the second greatest threat to biodiversity globally. Crayfish are especially robust invaders due to their omnivorous feeding behavior and ability to compete both directly and indirectly with native species. In the North Saskatchewan River (NSR) basin, the Northern Crayfish...

West-central, Alberta is subject to a growing number of resource extraction activities such as forestry that change ecosystem components and their structure. This area is important for the grizzly bear (Ursus arctos horribilis) population, which is considered to be a threatened species in Alberta...

Spring 2015
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...

Spring 2014
Sea ice in Hudson Bay is melting earlier and freezing later as the climate warms, resulting in declines in the condition, survival, and population size of polar bears (Ursus maritimus) in the Western Hudson Bay population. The objectives of this study are to analyze temporal variation in...

Spatial heterogeneity of buffaloberry (Shepherdia canadensis) in relation to forest canopy patterns and its importance for grizzly bear (Ursus arctos) resource selection
DownloadFall 2016
Spatial heterogeneity inherent in the environment influences how animals respond to their surroundings, especially as it relates to the variability of their food resources. Heterogeneity in specific elements of vegetation, such as the spatial pattern of a single plant species, can be defined...

The potential influence of mountain pine beetle (Dendroctonus ponderosae) control harvesting on grizzly bear (Ursus arctos) food supply and habitat conditions in Alberta
DownloadFall 2012
In response to the mountain pine beetle (Dendroctonus ponderosae) threat in Alberta, forest companies plan to surge harvest 75% of susceptible (mature) lodgepole pine (Pinus contorta) stands over 20 years. To assess potential changes to grizzly bear (Ursus arctos) habitat, I projected food...

Understanding the regeneration stage of any species is key to determining the processes that lead to population persistence and structure, community development, and succession. In the case of the endangered whitebark pine (Pinus albicaulis), knowledge of regeneration processes will be important...
