A burning question: The spatial response of woodland caribou to wildfire in northeastern Alberta
DownloadSpring 2020
The Canadian Federal Recovery Strategy for woodland caribou classifies areas burned by wildfire in the last 40 years as disturbed habitat for woodland caribou. This delineation of fire disturbance has major economic and social implications across Canada. Caribou have been shown to avoid burned...

Fall 2020
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...

Examining predation risk and antipredator responses of snowshoe hares in Northern Canada’s boreal forest
DownloadFall 2020
Predators limit prey populations not only through direct killing of prey but also through changes in behavior due to predation risk and negative fitness consequences that result. Prey species are known to respond to both predictable (e.g. risky times and places) and unpredictable variation (e.g....

Fall 2020
Understanding the causes behind population cycles is a fundamental issue in ecology, and has been the focus of research for decades. One of the most prominent examples of cyclical species is the snowshoe hare (Lepus americanus), a primary prey species in the North American boreal forest that...

Examining the impact of climate change on snowshoe hare demography and community interactions in the northern boreal forest
DownloadSpring 2020
Ecologists are under increasing pressure to predict the influence of climate change on species demography along with the broader impacts on community and ecosystem structure. Predicting community responses to climate change, however, is a formidable challenge, that can be ameliorated by...

Fall 2017
The degree to which predator and prey distributions overlap in space influences the probability of encounters between predator and prey, kills of prey, and consequently, how each species’ abundance varies in time and in space. Predator and prey attempt to increase or decrease overlap respectively...

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...

Resources and Reproductive Trade-offs Affect Fitness, Life History Traits, and Sexual Selection in Red Squirrels
DownloadSpring 2017
Animals face trade-offs throughout life between competing functions, such as between self-maintenance, reproduction, and survival. Resource allocation between these competing functions leads to different patterns of life history traits, changes in investment in reproductive effort, and different...

Snowfall, travel speed, and seismic lines: The effects of snow conditions on wolf movement paths in boreal Alberta
DownloadSpring 2016
In the winter, snow can present a major challenge to large mammals by impeding locomotion, limiting food availability, and imposing additional energetic costs during travel. This thesis examines the effects of snow conditions on the fine-scale movement patterns of grey wolves (Canis lupus) in a...

Fall 2015
The boreal ecotype of woodland caribou (Rangifer tarandus caribou) is federally listed as Threatened due to population declines throughout its distribution. High mortality rates of neonate calves (≤ 4 weeks old) due to predation are a key demographic factor contributing to population declines...
