Fall 2009
I investigated cellular mechanisms of ion and acid-base transport in rainbow trout (Oncorhyncus mykiss), crabs (Neohelice granulata), zebrafish (Danio rerio), Pacific hagfish (Eptatretus stoutii), and mosquito larvae (Aedes aegypti) with a primary focus on discerning the mechanisms governing ion...

Description of new species of Osteostraci from the Man On The Hill locality, Northwest Territories, Canada, with consideration of the phylogenetic and biogeographic significance of the new taxa
DownloadFall 2011
The Lochkovian (Lower Devonian) Man on the Hill (MOTH ) locality, Northwest Territories, Canada, is a Konservat-Lagerstätte, where articulated early vertebrate remains are found. Among the early vertebrates preserved at the MOTH locality are the Osteostraci. Many specimens of osteostracan have...

Early late Paleocene mammals from the Roche Percée local fauna, southeastern Saskatchewan, Canada
DownloadFall 2009
The occurrence of vertebrate fossils from the Ravenscrag Formation near Roche Percée, southeastern Saskatchewan, Canada, documents the presence of a large and diverse assemblage of early late Paleocene (approximately 58 million years) mammals. Previous studies of the Roche Percée localities have...

Spring 2012
Decades of fish introductions into mountain lakes have altered invertebrate communities. I assessed the current status of fish populations and their effects on crustacean zooplankton communities by sampling 37 lakes in the mountain parks, where stocking practices had been halted over 25 years...

Spring 2014
Anthropogenic contaminants can impair olfactory responses to natural odorants. In fishes, these impairments may be used as a metric of sub-lethal toxicity. My studies aimed to determine the effects of two contaminant sources on fish olfaction as measured by electro-olfactography (EOG). The...

Genetic structure of a large recolonizing carnivore: the case of the northern cougars (Puma concolor)
DownloadFall 2023
Anthropogenic activities have pressured and altered landscapes resulting in extinctions and extirpations. However, increased conservation efforts and changing management strategies in some large carnivores have resulted in population and range expansion. Population growth and range expansion are...

Since antiquity, fever has been documented as a physiological response to infection characterized by an increase in body temperature. Though fever is commonly regarded as a deleterious symptom of inflammation and is often suppressed using NSAID drugs, little is known about the effects that fever...

Occupancy, Abundance, and Summer Ecology of the Western Tiger Salamander (Ambystoma mavortium Baird) in the Beaver Hills, Alberta
DownloadSpring 2016
The western tiger salamander (Ambystoma mavortium Baird) is a ‘species of special concern’ in the Canadian prairie provinces. Potential declines caused by habitat loss and fragmentation, emergent diseases, and fish stocking are reasons cited for this species conservation status. However, little...

Survey, host preference and infectivity of Phasmarhabditis californica (Family: Rhabditidae) on pest slugs
DownloadFall 2023
Patuwatha Withanage, Dayani B. M.
Certain slug species are considered agricultural and horticultural pests worldwide. Nematodes offer a potential solution as biocontrol agents in controlling slug populations due to their natural associations with terrestrial gastropods. In some cases, they provide higher specificity and more...

Systematics and palaeobiology of the crested hadrosaurine Saurolophus from Canada and Mongolia
DownloadFall 2011
Reappraisal of Saurolophus confirms Saurolophus osborni and Saurolophus angustirostris as distinct species. Synapomorphies of Saurolophus include a spike-like pseudonarial crest formed by the nasals, frontals, and prefrontals; tripartite frontals with anteroventral and posterodorsal extensions...
