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...

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...

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...

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...

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...

Spring 2010
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...

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...

The Influence of a Railway on Grizzly Bears (Ursus arctos) in Canada’s Rocky Mountain Parks
DownloadSpring 2019
Linear features such as roads and railways threaten wildlife directly through collisions with vehicles. Although the adverse effects of roads on wildlife have been extensively studied resulting in widespread mitigation measures (e.g. fencing and highway crossing structures), far less attention...
