A trophic cascade recently has been reported among wolves, elk, and aspen on the northern winter range of Yellowstone National Park, Wyoming, USA, but the mechanisms of indirect interactions within this food chain have yet to be established. We investigated whether the observed trophic cascade...
Reintroduction of wolves (Canis lupus) to Yellowstone National Park in 1995–1996 has been argued to promote a trophic cascade by altering elk (Cervus elaphus) density, habitat-selection patterns, and behavior that, in turn, could lead to changes within the plant communities used by elk. We...
This manual attempts to summarize and highlight information to assist in defining species habitat relationships relevant to Alberta environments and for a number of Alberta wildlife species. The degree of specificity of the summaries, in part or whole, varies according to the background...
Trade-offs between predation risk and forage differ between migrant strategies in a migratory ungulateDownload
Trade-offs between predation risk and forage fundamentally drive resource selection by animals. Among migratory ungulates, trade-offs can occur at large spatial scales through migration, which allows an \"escape'' from predation, but trade-offs can also occur at finer spatial scales. Previous...
The life cycle and systematics of Parelaphostrongylus odocoilei (Nematoda: Metastrongyloidea), a a parasite of mule deer (Odocoileus hemionus hemionus), with special reference to the molluscan intermediate hostDownload
Doctoral thesis. Study area was within a 9 km radius of Jasper townsite.
Masters thesis. Mountain caribou studied from September 1975 to December 1977 from both population and phytosociological viewpoints. // "The Alberta Fish and Wildlife Division and Northwood are gratefully acknowledged for their assistance" -- p. viii.
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,...
State-space models link elk movement patterns to landscape characteristics in Yellowstone National ParkDownload
Explaining and predicting animal movement in heterogeneous landscapes remains challenging. This is in part because movement paths often include a series of short, localized displacements separated by longer-distance forays. This multiphasic movement behavior reflects the complex response of an...
Spatial Predation Risk and Interactions Within a Predator Community on the Rocky Mountains East Slopes, AlbertaDownload
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,...
