Spring 2010
Carbon isotope analyses of gases extracted from drilling muds while drilling in the Western Canada Sedimentary Basin (WCSB) can be used to create carbon isotopic depth profiles. These profiles provide essentially continuous data through the stratigraphic section, offering a unique opportunity to...

Roads are a prevalent, ever-increasing form of human disturbance on the landscape. In many places in western North America, energy development has brought human and road disturbance into seasonal winter range areas for migratory elk. In this population, I studied individual habitat selection...

Proliferative Signals Regulate Hemocyte Development and Intestinal Immunity in Drosophila melanogaster.
DownloadSpring 2015
The innate immune system is an ancient line of resistance against intrusive microbial threats. This system integrates cellular, humoral, and barrier defenses to generate a protective immune response. These divisions are indispensable and conserved between Drosophila and mammals. Hemocytes are the...

Fall 2010
The reflection seismic experiment results in a measurement(reflection seismic data) of the seismic wavefield. The linear Born approximation to the seismic wavefield leads to a forward modelling operator that we use to approximate reflection seismic data in terms of a scattering potential. We...

Reimaging Resource Constraints and Affordances: Smallholder, Environment and State Dynamics in Wello, Ethiopia
DownloadFall 2012
In this dissertation, I explore and analyze smallholders’ perceptual and cultural understandings of environmental opportunities and constraints regarding land, soil, rain and trees in mixed-crop-livestock agriculture among rural communities of Wärräbabbo in Wello, northeast Ethiopia. Also, I...

Snowfall, travel speed, and seismic lines: The effects of snow conditions on wolf movement paths in boreal Alberta
DownloadSpring 2016
In the winter, snow can present a major challenge to large mammals by impeding locomotion, limiting food availability, and imposing additional energetic costs during travel. This thesis examines the effects of snow conditions on the fine-scale movement patterns of grey wolves (Canis lupus) in a...

Subduction related crustal and mantle deformations and their implications for plate dynamics
DownloadFall 2010
Ocean-continent convergence and subsequent continental collision are responsible for continental growth, mountain building, and severe tectonic events including volcanic eruptions and earthquake activity. They are also key driving forces behind the extensive thermal and compositional...

The Impact of the COVID-19 Pandemic on Food Security and Food Sovereignty in Nunavut Communities
DownloadFall 2021
Background: For those living in regions already experiencing health and social difficulties, the COVID-19 pandemic and resulting policies to reduce spread have the potential to exacerbate existing issues, including increasing food insecurity in households. In Nunavut, where 70% of children are...

The Migration of Zimbabweans to South Africa and their Working and Living Conditions, 2000-2010
DownloadFall 2016
In this dissertation, I focus on the migration of Zimbabweans to South Africa and on their living conditions after they settled there. I cover the years from 2000 to 2010. This migration is important to study for several reasons. The departure of Zimbabweans during those years was extraordinary....

The migratory life history and physiology of arctic char, Salvelinus alpinus, navigating change in the Canadian North
DownloadFall 2015
Global climate change (GCC) is most pronounced at higher latitudes; to what degree northern migratory fish species can tolerate this change remains largely unknown. Imminent effects of GCC on arctic rivers include warmer water temperatures and changes in the timing, frequency and magnitude of...
