Spring 2013
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...

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...

Spatial Predation Risk and Interactions Within a Predator Community on the Rocky Mountains East Slopes, Alberta
DownloadSpring 2019
Understanding how large carnivores spatially partition the landscape is essential for understanding how they collectively pose risk to their prey. Most research on predation risk focuses on how prey respond to a single predator species, but prey respond to a community of predators. Additionally,...

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...

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...

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...

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...

Dall sheep (Ovis dalli dalli), grizzly bear (Ursus arctos) and wolf (Canis lupus) interactions in the Northern Richardson Mountains, Canada

Lambert Koizumi, Catherine M S
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...

Using drilled-undrilled shell damage analysis to estimate crushing predation frequencies in modern marine gastropod assemblages
DownloadSpring 2010
Predation is a frequently studied subject, but estimating crushing predation in mollusk communities is challenging. Shells record successful attacks, but it is not always possible to identify attacks on an individual basis. Repair scar frequency is a common proxy for crushing mortality, but shell...

A comparison of passive monitoring methods for gray wolves (Canis lupus) in Alberta, Canada
DownloadSpring 2019
Remote camera traps are often applied to large mammal conservation and management programs because they are cost-effective, allow for repeat surveys, and can be deployed for long time periods. Additionally, statistical advancements in calculating population metrics, such as density, from camera...
