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...

The use of rayon in 1920s and 1930s garments confronts conservators with new challenges: definitive fibre identification involves more than basic microscopy and treatment can be difficult with little available research on early rayon and its conservation. Rayon is expected to degrade similarly to...

Identifying seasonal Lake Sturgeon (Acipenser fulvescens) movement patterns and habitat selection in the South Saskatchewan River Basin
DownloadFall 2016
Lake Sturgeon (Acipenser fulvescens Rafinesque 1817) have experienced population declines throughout their range. In Alberta, low density age-class distributions, irregular recruitment, critically low spawning potential ratios and other factors led to a 2007 designation of “Threatened” for this...

Dynamics in wildlife populations emerge from the interactions between individuals and their environment. Constraints between individual nutrition and food availability are therefore fundamental to understanding how species adapt to environmental variability and to identify mechanisms controlling...

Mitigating the Effects of Human Activity on Grizzly Bears (Ursus arctos) in Southwestern Alberta.
DownloadSpring 2015
Anthropogenic habitat loss and alteration, as well as human-caused mortalities associated with increasing access, threaten grizzly bear populations across much of their North American range. This research investigates strategies for mitigating the negative effects of human activities on grizzly...

Movement and Habitat Use of the Long-Toed Salamander (Ambystoma macrodactylum) in Waterton Lakes National Park, Alberta
DownloadFall 2015
Population estimates for adult long-toed salamander (Ambystoma macrodactylum) at Linnet Lake in Waterton Lakes National Park, Alberta, showed a 60% decline from 1994 and 2008 –2009. To prevent further decline, in 2008 Parks Canada installed four under-road crossing structures (tunnels) and...

Offsetting approved harmful anthropogenic impacts in the 21st century – Insights into global offsetting practices, habitat banking as an alternative offsetting mechanism and application of habitat enhancement in northern boreal lake systems
DownloadFall 2022
Land-use change via human development is a major driver of biodiversity and habitat area loss and ecosystem function impairment. To reduce these impacts, billions of dollars are spent on environmental offsets, aimed to compensate for authorized negative impacts. Studies evaluating offset project...

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...

Spatial Predation Risk and Interactions Within a Predator Community on the Rocky Mountains East Slopes, Alberta
DownloadSpring 2019
Understanding how large carnivores spatially partition the landscape is essential for understanding how they collectively pose risk to their prey. Most research on predation risk focuses on how prey respond to a single predator species, but prey respond to a community of predators. Additionally,...

Recent research indicates climate change will be amplified in Polar Regions, which will cause decreases to sea ice thickness and extent throughout the Arctic. Polar bears (Ursus maritimus) will be directly affected by changes to Arctic sea ice conditions because they rely on the ice substrate...
