Biological and environmental correlates of cougar (Puma concolor) survival in west central Alberta
DownloadSpring 2023
Large carnivores have a significant role in ecosystems and their role as apex predators can have cascading effects that influence ecosystem stability. Managing large carnivores requires an understanding of how they use the land and their vital rates, including survival. For cougars (Puma...

Conserving cougars in a rural landscape: habitat requirements and local tolerance in west-central Alberta
DownloadSpring 2011
Maintaining large carnivores in human-dominated landscapes poses a significant conservation challenge. Extirpation is common because of habitat loss or direct persecution. I studied cougar habitat selection and human perception of cougars in west-central Alberta to better understand...

Predation by cougars (Puma concolor) variously can structure ecosystems and preserve biodiversity, engender conflict where livestock and pets are killed, and even drive prey populations to extinction. Effective management requires a firm grasp of the ecological drivers of predation, but these...

In western North America cougar populations are increasing and expanding eastward. Simultaneously, growing human populations are creating new challenges for managers charged with maintaining the viability of cougar populations and their ungulate prey. Information on how cougars respond to...

Industrial development is transforming Alberta's landscapes, with largely unquantified effects on wildlife species. Open-pit mining is occurring on vast expanses, most notably for bitumen but also extensively for coal in a rich seam that traverses the province. Major concerns have developed over...

Interactions between the forest tent caterpillar (Malacosoma disstria Hubner) and its natural enemies: the effects of forest composition and implications for outbreak spread
DownloadFall 2011
Forest tent caterpillar (Malacosoma disstria Hübner; FTC), a major defoliator of aspen trees, occupies both aspen and mixedwood forest stands in Alberta’s boreal forest. Forest stand composition could influence the spatial pattern of FTC outbreaks if mortality from natural enemies differs...

The current rate and extent of human-induced changes to the environment are unprecedented. There is an urgent need to understand and predict the dynamics of coupled human and natural systems so that we can maintain the ecosystem services on which we depend. Temperate coastal regions have...

Estimating annual wolf kill rates and composition is important for assessing the impact of wolves on their prey and managing wolf-ungulate dynamics. Most studies have focused on kill rates of wolves in winter or single-ungulate dominated systems. I used high intensity GPS tracking combined with...

Spatial ecology of cougars (Puma concolor) in the Cypress Hills: Implications for human-cougar interactions and range expansion
DownloadFall 2013
Cougar (Puma concolor) range is expanding eastward in North America. Understanding how range expansion is occurring in a human-dominated landscape is needed to manage the social and ecological implications of a returning large carnivore. To address this, I used GPS-radio collars and...
