A multi-scale test of the forage maturation hypothesis in a partially migratory ungulate population
Download2008
McDermid, G., Hebblewhite, M., Merrill, E.
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...

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...

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...

Livestock trampling impacts have been assessed in many Alberta grassland ecosystems, but the impacts of animal trampling on Aspen Boreal ecosystems have not been documented. This study compared the effects of high intensity [4.16 animal unit month per ha (AUM) ha-1] short-duration grazing (SDG)...

Roads are a prevalent, ever-increasing form of human disturbance on the landscape. In many places in western North America, energy development has brought human and road disturbance into seasonal winter range areas for migratory elk. In this population, I studied individual habitat selection...

Nutritional Significance of Wapiti (Cervus elaphus) Migrations to Alpine Ranges in Western Alberta, Canada
Download1989
Morgantini, L.E., Hudson, R.J.
This study was designed to provide a better understanding of the nutritional significance of wapiti (Cervus elaphus) migrations from low-elevation winter ranges onto high-elevation alpine summer ranges. The study focused on a population along the east slopes of the Rocky Mountains in western...

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...

Hurd, T.E., Kloppers, E.L., St. Clair, C.C.
Wildlife habituation near urban centers can disrupt natural ecological processes, destroy habitat, and threaten public safety. Consequently, management of habituated animals is typically invasive and often includes translocation of these animals to remote areas and sometimes even their...
