The Influence of a Railway on Grizzly Bears (Ursus arctos) in Canada’s Rocky Mountain Parks
DownloadSpring 2019
Linear features such as roads and railways threaten wildlife directly through collisions with vehicles. Although the adverse effects of roads on wildlife have been extensively studied resulting in widespread mitigation measures (e.g. fencing and highway crossing structures), far less attention...

Headgear are cranial appendages usually seen in males of infraorder Pecora. This trait is used to determine hierarchy and gain access to mates. In bighorn sheep, males or rams have impressively large horns that are made of keratin and cancellous bone. These horns are used in yearly combats to...

The Influence of Land-cover Type and Vegetation on Nocturnal Foraging Activities and Vertebrate Prey Acquisition by Burrowing Owls (Athene cunicularia).
DownloadFall 2012
Studies of habitat selection by foraging animals assume patterns of animal presence correlate with successful foraging, without explicit evidence this is valid. I used GPS dataloggers and digital video recorders to determine precise locations where nocturnally foraging Burrowing Owls captured...

The influence of larval diet and microsporidian infection on life history traits of the forest tent caterpillar, Malacosoma disstria Hübner (Lepidoptera: Lasiocampidae)
DownloadFall 2021
The forest tent caterpillar (FTC), Malacosoma disstria Hübner (Lepidoptera: Lasiocampidae), is an important ecological disturbance factor of deciduous hardwood trees in North America. Disturbance is greater during outbreaks; a cyclical phenomenon in which large numbers of FTC larvae cause...

The interactive effects of climate, social structure, and life history on the population dynamics of hoary marmots (Marmota caligata)
DownloadFall 2010
I used 8 years of mark-recapture data to test alternative hypotheses about the relative influence of winter climate, social structure, and life history on survival, reproduction, and population dynamics of hoary marmots (Marmota caligata) in the southwest Yukon. Climate, characterized by the...
