Habitat selection and food-web relations of Horned Grebes (Podiceps auritus) and other aquatic birds on constructed wetlands in the Peace Parkland, Alberta, Canada
DownloadFall 2009
I investigated if constructed wetlands provide breeding habitat for the Horned Grebe (Podiceps auritus) in northwest Alberta. Over two years, I conducted bird surveys of 201 borrow-pits (ponds created during road construction) and 18 natural wetlands and collected data on local habitat and...

The western toad (Anaxyrus boreas, formerly Bufo boreas) is one of many amphibian species considered to be at risk of extinction (COSEWIC status is Special Concern). I examined habitat use patterns of the western toad using several methods to gain a better understanding of its habitat...

Spring 2014
The worldwide biodiversity crisis has intensified the need to better understand how biodiversity and human disturbance are related. Yet this relationship lacks both consensus in theoretical expectations and consistency in observed empirical patterns. I present one of the largest extent studies...

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...

Limnology of a Large Northern Lake (Lhù’ààn Mânʼ [Kluane Lake], Yukon) in an Era of Reconciliation and Rapid Climate Change
DownloadSpring 2022
Almost 60% of Canada’s freshwater drains North, where air temperatures are increasing at twice the global rate. Despite the exposure of northern lakes to higher rates of change and their ecological, hydrological, and cultural importance, baseline knowledge and monitoring of their water properties...

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...

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...

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 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...

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...
