Spring 2011
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, Canada
DownloadSpring 2012
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...

Influence of Anthropogenic Development on Burrowing Owl Habitat Selection, Survival, and Reproductive Success
DownloadFall 2015
Anthropogenic development may influence the choices animals make and their resulting reproductive success and survival. If such choices are maladaptive, the impact of changes to their habitat could be catastrophic to populations that are small or declining. The Canadian prairies have changed...

Population, individual and behavioural approaches to understanding the implications of habitat change for arctic ground squirrels
DownloadFall 2012
The ecological niche describes the entire set of resources and environmental conditions suitable for species to occur and persist. In northern ecosystems, rapid climate change appears to be altering these conditions and increasing the likelihood of shifts in distribution and abundance of species,...

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...
