Applications of learning theory to human-bear conflict: the efficacy of aversive conditioning and conditioned taste aversion
DownloadSpring 2011
I tested the efficacy of aversive conditioning (AC) and conditioned taste aversion (CTA) on American black bears (Ursus americanus) in Whistler, British Columbia. Black bears subjected to 3-5 day AC programs responded by increasing their wariness toward humans, while control bears habituated. ...

Aversive conditioning of grizzly bears produces high probabilities of retreat from human-bear conflict locations
DownloadSpring 2024
Parks and protected areas provide important refugia for source populations of threatened grizzly bears in Alberta, where high human-use and recreation can cause human-bear conflict. Many jurisdictions in Alberta and beyond use hazing and aversive conditioning (hereafter AC) programs to deter...

Aversive conditioning on horse back: A management alternative for grassland systems threatened by sedentary elk populations
DownloadFall 2009
Loss of migratory behaviour in ungulates has been observed worldwide and invites new tools for managing the habitat degradation that results from these sedentary populations. We assessed use of aversive conditioning on horseback as a means of reducing grazing pressure and restoring migratory...

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...

Landscape Ecology of Mule Deer (Odocoileus hemionus) and White-tailed Deer (O. virginianus) with Implications for Chronic Wasting Disease
DownloadFall 2012
Chronic wasting disease (CWD) is a fatal prion disease of cervids that continues to spread into new regions of Canada despite containment efforts. I examine the importance of landscape connectivity using circuit theory and source/sink habitats that are based on selection, survival and...

Optimal use of resources: classic foraging theory, satisficing and smart foraging – modelling foraging behaviors of elk
DownloadSpring 2010
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...
