Fall 2016
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...

Niche partitioning and spatial variation in abundance of Rock (Lagopus muta) and White-tailed Ptarmigan (L. leucura): a case of habitat selection at multiple scales
DownloadSpring 2010
Climate change can affect habitat availability and species interactions at several spatial and temporal scales. I explored niche partitioning and spatial variation of Rock (Lagopus muta) and White-tailed Ptarmigan (L. leucura) in southwest Yukon. I examined habitat selection of foraging areas...

Occupancy, Abundance, and Summer Ecology of the Western Tiger Salamander (Ambystoma mavortium Baird) in the Beaver Hills, Alberta
DownloadSpring 2016
The western tiger salamander (Ambystoma mavortium Baird) is a ‘species of special concern’ in the Canadian prairie provinces. Potential declines caused by habitat loss and fragmentation, emergent diseases, and fish stocking are reasons cited for this species conservation status. However, little...

Spring 2015
Polar bears (Ursus maritimus) enter a period of intensified feeding in the spring, which allows for the accumulation of energy stores critical to surviving the open water season. Study on polar bear predation has been limited by sample size and spatial extent, and hypotheses on the demographic...

Polar bear (Ursus maritimus) foraging, spatial, and energetics ecology in the changing Arctic
DownloadFall 2020
Climate warming in the Arctic has resulted in rapid and extensive changes to sea ice dynamics and profound ecological impacts, including changes to the timing of life history events, community structure, and food web dynamics. Sea ice-dependent species such as polar bears (Ursus maritimus) are...

Spring 2014
Sea ice in Hudson Bay is melting earlier and freezing later as the climate warms, resulting in declines in the condition, survival, and population size of polar bears (Ursus maritimus) in the Western Hudson Bay population. The objectives of this study are to analyze temporal variation in...

Spring 2020
The choices animals make such as what habitat to use or where to live are influenced by individual behavior and life history traits. Gaining insight on space use patterns and habitat selection of a species can help wildlife managers in understanding social dynamics, population size and density,...

Spatial ecology of cougars (Puma concolor) in the Cypress Hills: Implications for human-cougar interactions and range expansion
DownloadFall 2013
Cougar (Puma concolor) range is expanding eastward in North America. Understanding how range expansion is occurring in a human-dominated landscape is needed to manage the social and ecological implications of a returning large carnivore. To address this, I used GPS-radio collars and...

Survey, host preference and infectivity of Phasmarhabditis californica (Family: Rhabditidae) on pest slugs
DownloadFall 2023
Patuwatha Withanage, Dayani B. M.
Certain slug species are considered agricultural and horticultural pests worldwide. Nematodes offer a potential solution as biocontrol agents in controlling slug populations due to their natural associations with terrestrial gastropods. In some cases, they provide higher specificity and more...

Systematics and palaeobiology of the crested hadrosaurine Saurolophus from Canada and Mongolia
DownloadFall 2011
Reappraisal of Saurolophus confirms Saurolophus osborni and Saurolophus angustirostris as distinct species. Synapomorphies of Saurolophus include a spike-like pseudonarial crest formed by the nasals, frontals, and prefrontals; tripartite frontals with anteroventral and posterodorsal extensions...
