Influence of Anthropogenic Development on Burrowing Owl Habitat Selection, Survival, and Reproductive Success
DownloadFall 2015
Anthropogenic development may influence the choices animals make and their resulting reproductive success and survival. If such choices are maladaptive, the impact of changes to their habitat could be catastrophic to populations that are small or declining. The Canadian prairies have changed...

Landscape Ecology of Mule Deer (Odocoileus hemionus) and White-tailed Deer (O. virginianus) with Implications for Chronic Wasting Disease
DownloadFall 2012
Chronic wasting disease (CWD) is a fatal prion disease of cervids that continues to spread into new regions of Canada despite containment efforts. I examine the importance of landscape connectivity using circuit theory and source/sink habitats that are based on selection, survival and...

Local and regional demography in a migratory forest songbird and effects of forest management intensity
DownloadSpring 2014
The numerical response of forest birds to habitat alteration has been well documented in North America, but the underlying demographic processes driving these changes remain largely unknown. Among species sensitive to such alterations, the Ovenbird (Seiurus aurocapilla) shows one of the largest...

Mapping a Species-level Trophic and Non-trophic Multilayer Network of Known Interactions for Boreal Tetrapods of North America
DownloadFall 2021
Mapping trophic and non-trophic species interactions and mapping ecosystem-wide ecological networks have become important research avenues in network ecology, but until recently these two avenues have been separate endeavors. Now, a framework exists to combine multiple interaction types into...

Microbiota are ubiquitous in nature. Similarities as well as differences are present between microbiota in animals and fermentation systems. The aim of the PhD project was to investigate factors affects microbial ecology in rodent and sourdough models. To determine how compromised health of the...

Natural regeneration in the boreal forest: seedling establishment and success in western North American and European boreal forests
DownloadFall 2014
As the costs and ecological implications of intensive forest management rise, alternative management strategies that minimize intervention become more desirable options, particularly natural regeneration. Two locations were studied: the boreal mixedwoods of western North America (Alberta) and...

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...

Spring 2013
The Rocky Mountain apollo butterfly, Parnassius smintheus, and its host-plant Sedum lanceolatum, are endemic to open alpine meadows threatened by the encroachment of trees. I explore variability in interactions between P. smintheus and S. lanceolatum relative to the treeline-delimited meadow...

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...
