Salmonids are stocked around the world to create and enhance fishing opportunities. Most research into the effects of trout on lake ecosystems has occurred in alpine and other oligotrophic systems, often naturally fishless, where negative impacts are likely. In contrast, I investigated effects of...
I investigated the effect of energy sector development and introduced crested wheatgrass (Agropyron cristatum) on grassland birds on Canadian Forces Base Suffield. I conducted point counts and mapped breeding territories in 2007 and 2008 for Savannah sparrows (Passerculus sandwichensis),...
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...
Movement and Habitat Use of the Long-Toed Salamander (Ambystoma macrodactylum) in Waterton Lakes National Park, AlbertaDownload
Population estimates for adult long-toed salamander (Ambystoma macrodactylum) at Linnet Lake in Waterton Lakes National Park, Alberta, showed a 60% decline from 1994 and 2008 –2009. To prevent further decline, in 2008 Parks Canada installed four under-road crossing structures (tunnels) and...
I investigated the population and landscape genetics of Arctic Grayling (Thymallus arcticus) distributed throughout several connected river systems in Alberta, Canada. Broad- and fine-scale population structure was examined by genotyping nine microsatellite loci in 1,116 Arctic Grayling captured...
Postbreeding movement patterns and multiscale habitat use of adult wood frogs (Lithobates sylvaticus) at urban wetlands of Edmonton, Alberta.Download
Many studies have focused on the effects of urbanization on amphibian species richness, abundance and diversity, but few studies have quantified the effect on amphibian movement behaviour or habitat use. At 11 urban wetlands in Edmonton, Alberta, I examined the postbreeding movement behaviour and...
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...
