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...

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...

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...

Ungulates are known to avoid predation by grouping up, increasing vigilance, and reducing residency time among preferred habitats. Similarly, shifting return rates may represent a means of pre-emptively minimizing exposure to risk by being less predictable on the landscape to predators. We...
