An adaptive approach to endangered species recovery based on a management experiment: reducing moose to reduce apparent competition with woodland caribou
DownloadFall 2013
Species that are rare yet widely distributed are among the most challenging to conserve. The mountain ecotype of woodland caribou (Rangifer tarandus) is declining because of apparent competition with non-caribou ungulates (NCU) such as moose (Alces alces). I experimentally assessed whether...

Fall 2013
Caribou (Rangifer tarandus L.) populations in Canada are threatened by climate change and anthropogenic landscape disturbance, which may negatively affect caribou energetics and range occupancy, with negative consequences for vital rates. Caribou are the basis of economy and spirituality for...

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...

Disruption in place attachment: Insights of young Aboriginal adults on the social and cultural impacts of industrial development in northern Alberta
DownloadFall 2009
People living in the north have been and will continue to be affected by increasing exploration and exploitation of the region's natural resources. To understand the human impacts a qualitative approach and sense of place, place attachment, and disruption in place theories were used to analyze...

EFFECTS OF CLIMATE CHANGE, VEGETATION AND ROADS ON CARIBOU DISTRIBUTION IN WESTERN NORTH-AMERICA
DownloadFall 2017
Caribou (Rangifer tarandus) are a vital component of the cultural history and contemporary existence of First Nations and northern communities. However, caribou habitat is increasingly threatened by cumulative effects of climate change and land-use pressures from human settlement, forestry, and...

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...

Fall 2014
Multiple carnivore species can have greater population limiting effects than single carnivores. Two coexisting carnivores can only be similar up to a certain extent. I investigate how two carnivores, wolves (Canis lupus) and cougars (Puma concolor), coexist through niche partitioning in the...

Let the winter sun shine on, let me feel the frost of dawn: Rangifer tarandus osteology, anatomy, and identity
DownloadFall 2020
Rangifer tarandus, the species which encompasses both caribou in North America and reindeer in Eurasia, is a keystone species for both the cultures and the ecosystems of the circumpolar world. Because of this, human interactions with reindeer and caribou throughout history are of great interest...

Measuring wildlife response to seismic lines to inform land use planning decisions in northwest Canada
DownloadFall 2012
Development of hydrocarbon resources across northwest Canada has spurred economic prosperity but also generated concerns over impacts to biodiversity. To balance these interests, comprehensive land use plans have been used to match targeted management strategies to ecological components deemed...

Fall 2015
Movement ecology thrives from a successful synergy of data and models. In a field where experiments are difficult or impossible, linking field data with mathematical and statistical models allows us to test hypotheses and increase our quantitative understanding of movement processes. Owing to...
