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...

Mating systems evolve in response to factors that influence the distribution and availability of mates. In turn mating systems can influence species life histories as a result of sexual selection. Most of what is known about sexual selection in large mammals comes from long-term studies of...

The net exchange of carbon greenhouse gases with high Arctic terrestrial and aquatic ecosystems
DownloadSpring 2015
Accelerated climate warming of Canada’s sparsely vegetated high Arctic has resulted in rapid environmental changes including loss of glacial ice, permafrost thaw, decreased snow cover and changing plant communities. These responses are causing mostly unknown changes to the natural cycling of the...

The roles of temperature and host plant interactions in larval development and population ecology of Parnassius smintheus Doubleday, the Rocky Mountain Apollo butterfly
DownloadFall 2011
Alpine environments are harsh and unpredictable. Exogenous factors such as weather might therefore be expected to dominate processes affecting population dynamics of alpine organisms, relative to endogenous factors including plant-animal interactions. The alpine butterfly Parnassius smintheus...

Tree population responses to extreme climate events to guide reforestation under climate change
DownloadSpring 2018
As climates warm and extreme climatic events occur with more frequency and severity, maintaining forest health and productivity may involve planting seed sources from warmer, drier areas. To guide such reforestation strategies, this work analyzes the risks of both climate change and assisted...

Spring 2016
Reclamation of northern disturbances is of increasing importance as industrial activities and associated infrastructure expands to accommodate growing human reliance on world ecosystems. Bryophytes are recognized as ecologically essential to northern ecosystems and effectively promoting their...

Although the pan-Inuit unikkaaqtuaq (story) of the origin of the Sea Woman is quite well-known among anthropologists, folklorists, and Religious Studies scholars, to date very little attention has been given to either the broader Sedna tradition, or its individual performances, as serious,...

Unseen and Unknown: Microbial Community Diversity in a Rapidly Changing High Arctic Watershed on Northern Ellesmere Island, Canada
DownloadFall 2018
Arctic watersheds are currently undergoing great alterations due to human induced climate change. Current models predict increases in High Arctic temperatures and precipitation of up to 8.3°C and 40%, respectively, by 2100, which will have profound impacts on the arctic hydrological cycle,...

Whose burden? A comprehensive approach to describing burden of disease by synthesizing evidence from diverse perspectives
DownloadFall 2018
Epidemiologists tasked with addressing public concerns about a specific health issue and developing effective public health strategies aimed at reducing related health risks must begin by describing the extent of the health threat in the target population. Typical approaches use quantitative...

Wildfires and climate change: their effects on moose (Alces alces) and white-tailed deer (Odocoileus virginianus) winter habitat in the boreal mixedwoods of Alberta, Canada
DownloadFall 2021
Understanding how species respond to wildfires and climate change is fundamental for land use management and biodiversity conservation. Wildfires provide generalist ungulates, such as moose (Alces alces) and white-tailed deer (Odocoileus virginianus), with high quantity and quality of winter...
