"Stories Matter:" A Narrative Inquiry Exploring First-Generation University Student Persistence
DownloadFall 2014
Though postsecondary participation has increased overall, the rate of participation has risen more sharply for middle-class students compared with working-class students (Knighton & Mirza, 2002). Especially pronounced is Krahn’s (2009) finding that children from families where at least one...

Brusnyk, L., Lewin, V., Roberts, W.
During June, July, and August of 1976 three species of amphibians were found within the Alberta Oil Sands Project area. The wood frog (Rana sylvatica) was the most abundant and widespread species and was collected at each of 20 sites examined. Boreal chorus frogs (Pseudacris triseriata...

Analytical Characterization of Halobenzoquinones as Emerging Disinfection Byproducts in Disinfected Water
DownloadSpring 2016
Water disinfection is necessary for killing pathogens, but it causes an unintended chemical risk from the formation of disinfection byproducts (DBPs). Epidemiological studies show a potential association of water disinfection with increased risk of bladder cancer. It is unknown what DBPs are...

Developing and Assessing an Environmental DNA Protocol for Detecting Amphibian Species in Lentic Systems in Alberta, Canada
DownloadSpring 2016
Global declines of amphibian populations have resulted in increased interest in determining and monitoring the geographic ranges for both endangered and invasive amphibian species. Monitoring programs rely on detection techniques to amass data, techniques that must be dependable in order to...

McCauley, E., Lewis, Mark A., Lutscher, F.
The question how aquatic populations persist in rivers when individuals are constantly lost due to downstream drift has been termed the “drift paradox.” Recent modeling approaches have revealed diffusion-mediated persistence as a solution. We study logistically growing populations with and...

Habitat use by the wood frog (Lithobates sylvaticus (LeConte, 1825)) within pothole wetlands modified by beaver (Castor canadensis Kuhl, 1820) in east-central Alberta
DownloadFall 2013
Studies of amphibian habitat use often focus on using landscape characteristics to predict occupancy at broad spatial scales, but few have investigated how amphibians use specific habitat features within a wetland, such as the distinct habitat features created by beavers. In pothole wetlands of...

The western toad (Anaxyrus boreas, formerly Bufo boreas) is one of many amphibian species considered to be at risk of extinction (COSEWIC status is Special Concern). I examined habitat use patterns of the western toad using several methods to gain a better understanding of its habitat...

Linking occurrence and fitness to persistence: habitat-based approach for endangered greater sage-grouse
Download2007
Detailed empirical models predicting both species occurrence and fitness across a landscape are necessary to understand processes related to population persistence. Failure to consider both occurrence and fitness may result in incorrect assessments of habitat importance leading to inappropriate...

This thesis focuses on formulating and analyzing non linear models for microbial dynamics vis-a-vis human and environmental health. Firstly, we develop and investigate a stoichiometric organic matter decomposition model in a chemostat culture that incorporates the dynamics of grazers. This...
