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...
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 rangeDownload
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. HelensDownload
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...
Optimal use of resources: classic foraging theory, satisficing and smart foraging – modelling foraging behaviors of elkDownload
It is generally accepted that the Marginal Value Theorem (MVT) describes optimal foraging strategies. Some research findings, however, indicate that in natural conditions foragers not always behave according to the MVT. To address this inconsistency, in a series of computer simulations, I...
Reproduction and transmission of the winter tick, Dermacentor albipictus (Packard) in central AlbertaDownload
Masters thesis. A two part study, involving a field and laboratory component, was developed to provide information on the reproductive performance and transmission of D. albipictus under field conditions and relate this information to the die-off of moose in Alberta.
Masters thesis. Examines relationship between moose browsing and willow growth on a moose winter range.
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,...
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.
