Beyond the host plant: Multi‐scale habitat models for a northern peripheral population of the butterfly, Apodemia mormo (Lepidoptera: Riodinidae)
DownloadSpring 2013
The Mormon metalmark (Apodemia mormo) butterfly is widely distributed throughout western North America. It is listed as threatened, however, in Saskatchewan, Canada because of a small population size within a restricted habitat. To most effectively manage for this species, land managers and...

Biological soil crusts in Alberta’s grasslands: increasing our knowledge of their taxonomy, diversity, and sensitivity to drought and defoliation
DownloadFall 2022
Biological soil crusts (BSCs) play a central role in the biodiversity, health, resilience, and function of drylands like Alberta’s grasslands. In Alberta, much of the biocrust cover consists of lichens, and many crusts are dominated by species of Cladonia. Despite the drought-resistant nature of...

Bitumen Extraction, Indigenous Land Conflicts, and Environmental Change in the Athabasca Oil Sands Region, 1963-1993
DownloadSpring 2021
This dissertation examines the first development phase of the Alberta oil sands industry from the 1960s to the early 1990s. It draws on public and private records from archives in Canada and the United States, the results of collaborative research with the Fort McMurray Métis, and oral history...

Black-tailed prairie dog declines in northwestern Mexico: species-habitat relationships in a changing landscape
DownloadFall 2009
One of the three largest systems of black-tailed prairie dog (BTPD) colonies is located in northwestern Chihuahua, Mexico. During the last two decades, the area occupied by these colonies has been highly reduced and fragmented. Previous studies suggested that agriculture, poisoning, cattle...

Understory protection is a harvesting approach that seeks to protect understory conifers during hardwood harvesting in mixedwood forests. While understory protection harvesting has been implemented for over a decade in Alberta, there has been no study of its ecological value to birds. We surveyed...

Boxed-in: Comparing Algorithms for Box-flight Mass-Balance Greenhouse Gas Flux Measurements from Mineable and In Situ Oil Sands Developments
DownloadSpring 2022
To combat global warming, Canada has committed to reducing greenhouse gases (GHGs) 40-45% below 2005 emission levels by 2025. Monitoring emissions and deriving accurate inventories are essential to reaching these goals. GHGs can be measured at a small scale, often using ground measurements which...

Chickadee behavioural response to varying threat levels of heterospecific and conspecific calls
DownloadFall 2015
Chickadees produce many vocalizations, including the chick-a-dee call that they use as a mobbing call in the presence of predators. Previous research has shown that chickadees produce more D notes in their mobbing calls in response to high-threat predators compared to low-threat predators, and...

Clinical, Laboratory and Treatment Outcome Characteristics of Foreign-Born Pulmonary Tuberculosis Patients in Alberta by Immigration Status, 2004-2013
DownloadFall 2017
Canada is a low TB incidence country, with a rate of 4.4 per 100,000 in 2014. Despite this low incidence rate, TB affects certain groups disproportionately, most notably foreign-born persons from high incidence countries and Indigenous peoples. This study compares clinical, laboratory, and...

Community ecology of ants (Hymenoptera: Formicidae) in the central sand hills of Alberta, and a key to the ants of Alberta.
DownloadFall 2012
In this study I examined ant biodiversity in Alberta. Over a two-year period, 41,791 ants were captured in pitfall traps on five sand hills in central Alberta and one adjacent aspen parkland community. Using additional collections, I produced a key to the 92 species of ants known from Alberta,...
