An adaptive approach to endangered species recovery based on a management experiment: reducing moose to reduce apparent competition with woodland caribou
DownloadFall 2013
Species that are rare yet widely distributed are among the most challenging to conserve. The mountain ecotype of woodland caribou (Rangifer tarandus) is declining because of apparent competition with non-caribou ungulates (NCU) such as moose (Alces alces). I experimentally assessed whether...

Personality has been documented in diverse taxa and growing attention is being directed towards the ecological implications of consistent variation in individual behaviour. These implications include the rise in habituation behaviour by wildlife living in human-disturbed areas, which has resulted...

Fall 2014
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...

Foraging-predator avoidance trade-offs made by migrant and resident elk (Cervus elaphus) on their sympatric winter range
DownloadFall 2009
Migratory behaviour of the Ya Ha Tinda (YHT) elk population is diminishing while the number of residents remaining on the YHT winter range year-round is increasing. Previous research addressing the fitness consequences of each migratory strategy assumed there was no advantage to either segment...

Forest Succession and Nutritional Carrying Capacity of Elk since the 1980 Eruption of Mount St. Helens
DownloadFall 2016
There has been increasing concern over declines in habitat quality for elk (Cervus elaphus) on industrial timber lands west of Mount St. Helens due to canopy closure and the loss of nutritional resources related to succession of early seral stands created by the 1980 eruption. Vegetative...

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,...

Succession, herbicides, forage nutrition and elk body condition at Mount St. Helens, Washington
DownloadSpring 2014
Concerns have been voiced over recent reductions in forest cutting, herbicide spraying, and past heavy grazing on nutritional resources for elk (Cervus elaphus) and their body condition in the Pacific Northwest. I evaluated the effects of herbicides and herbivory on elk forage in a paired,...

The Role of Human Altered Landscapes and Predators in the Spatial Overlap Between Moose, Wolves, and Endangered Caribou
DownloadFall 2014
Human altered landscapes can cause the endangerment or extinction of a species, not only by a direct loss of habitat but by altering predator-prey relationships. Predators can drive prey to extinction when the density of the predator becomes subsidized by another abundant, alternate prey. Such...

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...
