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 Quandary of the Sask Craton: Origin and Evolution of the Lithospheric Mantle beneath the Sask Craton
DownloadFall 2018
Mantle xenoliths from the Cretaceous (~106 to ~95 Ma) kimberlites at Fort à la Corne (FALC) present a unique opportunity to study the lithospheric mantle beneath the newly recognised Sask Craton. The Sask Craton, a small terrane with Archean (3.2 - 2.5 Ga) crustal ages, is enclosed in the...

The Structure and Dynamics of Fish Isotopic and Trophic Niches in Natural Lakes and Constructed Fisheries Offsets in the Alberta Oil Sands
DownloadFall 2022
Habitat offsets, where damages to natural ecosystems caused by socio-economic development projects are compensated for by the construction or restoration of other ecosystems, can contribute to biological conservation when implemented properly. But, large uncertainties remain surrounding our...

Through they Eyes of a Tree: Monitoring Environmental Change Using Stable Isotope Dendrochemistry
DownloadSpring 2013
Stable isotope dendrochemistry of needles, twigs, and tree rings were used to identify the impacts of a changing global atmosphere in two separate environments with different anthropogenic loads: the boreal forest surrounding the Athabasca Oil Sands region (AOSR), Alberta, Canada, subject to a...

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...

Variations in climatic conditions from the Cayman Islands through stable isotope and element analysis from corals and sediment cores; a 500,000 year record
DownloadFall 2020
The Caribbean region is particularly important to understanding global climate change and feedback systems because the tropics are the primary source of heat and water vapor for the atmosphere. The Caribbean region, however, is a relatively understudied area in terms of tracking climate change...

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...

Fall 2009
Woodland caribou population declines in west-central Alberta precipitated a wolfcontrol. This program to protect caribou could be compromised if (1) there are strong public pressures against helicopter gunning and strychnine poisoning of wolves and/or (2) other predators compensate to kill...
