The forage maturation hypothesis (FMH) proposes that ungulate migration is driven by selection for high forage quality. Because quality declines with plant maturation, but intake declines at low biomass, ungulates are predicted to select for intermediate forage biomass to maximize energy intake...
Ten yearling wapiti stags were used to investigate effects of winter nutrition on subsequent growth on summer pasture. One group of five (LOW) was wintered on medium-quality hay, and the other group of five (HIGH) was wintered on hay and alfalfa–barley pellets (16% crude protein). By the time...
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...
Data from the Alberta Agriculture Food and Rural Development data base, which keeps inventories of elk producers and velvet production information (n = 12 724), were used to estimate genetic and phenotypic variances, heritability and repeatability estimates for velvet antler using REML methods....
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.
