Dall sheep (Ovis dalli dalli), grizzly bear (Ursus arctos) and wolf (Canis lupus) interactions in the Northern Richardson Mountains, CanadaDownload
Assessing the impact of predators on a prey population is inherently challenging, a fortiori in remote ecosystems. With this thesis, I studied the interactions between a recently declining Dall sheep (Ovis dalli dalli) population and two predators: grizzly bears (Ursus arctos) and wolves (Canis...
Evaluation of Highway Mitigation on the Frequency of Wildlife-Vehicle Collisions on the Highway and an Adjacent Railway in a Montane EcosystemDownload
Transportation networks are expanding rapidly to meet increasing global demands to move people and cargo. These networks are essential to connect societies and economies but have several negative effects on wildlife populations including collisions with vehicles. Growing incidences and increasing...
Effective and adaptive conservation of a species requires knowledge of trend in abundance and distribution. Monitoring species that are highly mobile, cryptic, and occurring at low densities is especially challenging. This research investigates the local factors affecting the detectability of...
The Mackenzie Delta region, NWT, has a short growing season and highly seasonal climate, and brown bears (Ursus arctos) there face many challenges obtaining their nutritional requirements. Consumption of meat by brown bears is linked to increases in population density, fecundity, growth and body...
Getting to the root of the matter: grizzly bears and alpine sweetvetch in west-central Alberta, CanadaDownload
Wildlife habitat selection is influenced by gender, offspring-dependency, resource availability, and spatiotemporal variation in resource nutrition. In consideration of these factors, this thesis examines alpine sweetvetch (Hedysarum alpinum) root and its relationship to grizzly bears (Ursus...
Human-wildlife conflicts are a global conservation challenge. Reserves and protected areas usually do not adequately provide for the space needs of large carnivores, resulting in overlap between carnivore home ranges and private lands. Private lands often can provide valuable habitats, but...
A major side-effect of industrial activity is the associated linear-feature footprint and increase in recreational access. Alberta’s threatened grizzly bear (Ursus arctos) populations overlap with a multitude of different potential forms of human disturbance, including human recreational...
Because most grizzly bear mortalities occur near roads, the Province of Alberta plans to implement gated access management. Little is known about how grizzly bears will respond to road closures because the effects of roads are confounded by habitat and human use. I examined mechanisms...
Individual and Seasonal Variation in Grizzly Bear Selection for a Railway and other Linear Features in Banff National Park, CanadaDownload
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...
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...
