Fall 2016
As resource exploitation and development expands in northern Canada, threats to the ecological integrity of freshwater systems increase. In Canada, developments that could negatively affect aquatic ecosystems require offsetting or compensation measures. As a result of diamond mine development, a...

Fall 2014
The development of the Diavik diamond mine destroyed pristine lakes and streams in Barrenlands region of northern Canada. Subsequently, several fish habitat compensation projects were undertaken to offset these losses. The M-Lakes project was intended to enhance the productive capacity of a...

Dall sheep (Ovis dalli dalli), grizzly bear (Ursus arctos) and wolf (Canis lupus) interactions in the Northern Richardson Mountains, Canada

Lambert Koizumi, Catherine M S
Assessing the impact of predators on a prey population is inherently challenging, a fortiori in remote ecosystems. With this thesis, I studied the interactions between a recently declining Dall sheep (Ovis dalli dalli) population and two predators: grizzly bears (Ursus arctos) and wolves (Canis...

Effects of retrogressive thaw slumping on particulate organic carbon dynamics in the Northwest Territories, Canada
DownloadSpring 2022
Climate change is increasing the frequency and intensity of thermokarst and accelerating the delivery of terrestrial organic material from previously sequestered sources to aquatic systems, where it is subject to further biochemical alteration. Rapid climate change in the glacially conditioned...

Resource development can lead to the harmful alteration, disruption, or destruction of fish habitat. During Diavik Diamond Mine, Inc.’s (DDMI) development of its facilities at Lac de Gras (LDG), NWT, DDMI destroyed two small headwater lakes and associated streams. To help offset this loss, DDMI...

Fall 2020
Climate change is altering sea ice phenology, which forces polar bears (Ursus maritimus) to spend an increasing amount of time on land. Therefore, understanding movement ecology and terrestrial habitat selection of bears may become increasingly important for conservation planning. The Western...

Intrapopulation variability in wolf diet revealed using a combined stable isotope and fatty acid approach
DownloadSpring 2018
Naturally occurring stable isotope ratios and fatty acids are two types of chemical biomarkers frequently used to quantitatively estimate consumer diets. Stable isotope values in animal tissues and diets have been evaluated using Bayesian mixing models to provide dietary estimates of consumers in...

I investigated the population and landscape genetics of Arctic Grayling (Thymallus arcticus) distributed throughout several connected river systems in Alberta, Canada. Broad- and fine-scale population structure was examined by genotyping nine microsatellite loci in 1,116 Arctic Grayling captured...
