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...
Developing and Assessing an Environmental DNA Protocol for Detecting Amphibian Species in Lentic Systems in Alberta, CanadaDownload
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...
Habitat use by the wood frog (Lithobates sylvaticus (LeConte, 1825)) within pothole wetlands modified by beaver (Castor canadensis Kuhl, 1820) in east-central AlbertaDownload
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...
Occupancy, Abundance, and Summer Ecology of the Western Tiger Salamander (Ambystoma mavortium Baird) in the Beaver Hills, AlbertaDownload
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...
Reproduction and abundance of the wood frog (Lithobates sylvaticus) in post-harvest variable retention forestsDownload
Many aquatic-breeding amphibians require freshwater habitat for reproduction and terrestrial habitat for refuge, foraging, and overwintering. Variable retention harvesting is a technique where live trees and other forest features are retained during timber harvesting in patterns that emulate...
The value of stormwater wetlands for supporting multiple life-history stages of the wood frog (Lithobates sylvaticus) in the City of Edmonton, Alberta, CanadaDownload
I reviewed 32 urban amphibian studies from North America and found most amphibians respond negatively to urbanization (69 negative responses, 6 positive and 35 no effect). Additionally, I conducted amphibian surveys (adult, egg, larvae, and metamorphs) at 75 wetlands located throughout the City...
Using under-road tunnels to protect a declining population of long-toed salamanders (Ambystoma macrodactylum) in Waterton Lakes National ParkDownload
I investigated the value of under-road tunnels as a conservation strategy to protect a long-toed salamander population, in south-west Alberta, whose overwintering sites and breeding habitat (Linnet Lake) are separated by a road. I conducted a mark-recapture study from 2008-2009, capturing...
