Effects of burn severity and time since fire on songbird communities in the northern boreal forest
DownloadFall 2018
Wildfire shapes the boreal ecosystem in western Canada and thereby enhances and diminishes important breeding habitat for many songbird species. Two aspects of wildfire, burn severity and time since fire, fundamentally alter the forest structure that songbirds use. The objectives of this study...

Effects of energy development on habitat use of an avian peatland specialist and generalist at multiple spatial scales
DownloadFall 2020
With the persistent demand for petroleum energy products, the energy development footprint in northern Alberta continues to expand, perforating habitat in the boreal forest. Modern in situ, or below ground, bitumen extraction techniques have broadened the extent of accessible reserves and are...

Effects of linear anthropogenic corridors on insect pollinator movement and diversity, and understory shrub fruit production in the boreal forest of northeastern Alberta
DownloadSpring 2021
Fragmentation of habitats is a primary concern in the conservation of global biodiversity. Anthropogenic linear disturbances, such as roads, trails, and power lines, are a major source of habitat fragmentation worldwide. In Alberta’s boreal forest, a common, pervasive type of disturbance is...

In wildlife conservation, long-term monitoring is often justified by wildlife agencies as they allow managers to inform stakeholders, avoid conflicts, and to evaluate the results of management interventions. However, many wildlife agencies insufficiently or inadequately use these data in their...

Stable home ranges can emerge in a generic forager using a two-part memory system and rules derived from optimal foraging theory. My objective was to evaluate the underlying assumptions of this promising theoretical model using data from two populations of elk. Using a spatiotemporal scan...

Factors affecting the detectability and eastern distribution of grizzly bears in Alberta, Canada
DownloadFall 2013
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...

Threatened woodland caribou (Rangifer tarandus caribou) have experienced large range recessions and population declines across much of Canada’s boreal forest in the last century and have become a major focus of conservation efforts in the region. Habitat management strategies for woodland caribou...

Food availability and grizzly bear (Ursus arctos) selection of post-fire and thinned forests in the mountain national parks of Canada
DownloadFall 2018
Human-caused mortality and habitat loss have led to the extirpation of grizzly bears (Ursus arctos) across much of their North American range. Today, these factors continue to limit extant grizzly bear populations as productive habitats often occur in areas with elevated mortality risk creating...

From species to genes: ecological and evolutionary mechanisms structuring diversity in space and time
DownloadFall 2021
My Ph.D. thesis addresses three foundational questions in conservation biology: i) what is biodiversity and how is it best measured? ii) how does variation in habitat configuration, habitat composition, and environmental conditions affect emergent patterns of species diversity? and iii) how do...

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...
