Unique cellular interactions between the obligate intracellular bacteria Wolbachia pipientis and its insect host
DownloadFall 2011
Wolbachia are maternally inherited obligate intracellular bacteria found in arthropods, where they induce feminization, male-killing, parthenogenesis, and cytoplasmic incompatibility (CI). CI is conditional male sterility, in which Wolbachia-infected males successfully mate with infected females,...

Unseen and Unknown: Microbial Community Diversity in a Rapidly Changing High Arctic Watershed on Northern Ellesmere Island, Canada
DownloadFall 2018
Arctic watersheds are currently undergoing great alterations due to human induced climate change. Current models predict increases in High Arctic temperatures and precipitation of up to 8.3°C and 40%, respectively, by 2100, which will have profound impacts on the arctic hydrological cycle,...

Uptake of waterborne selenite, and its toxic effects, in the water flea (Daphnia magna), Westslope cutthroat trout (Oncorhynchus clarkii lewisi) and rainbow trout (Oncorhynchus mykiss)
DownloadSpring 2024
Selenium is an essential element, playing an important role in many physiological processes. However, it possesses a narrow margin between essentiality and toxicity. In aquatic systems, selenium is increasingly identified as a trace element of major concern with levels exceeding regulatory...

Use of an Acoustic Location System to Understand Songbird Response to Vegetation Regeneration on Reclaimed Wellsites in the Boreal Forest of Alberta
DownloadFall 2017
Limited information exists on the recovery of different ecosystem components following reclamation of oil and gas wellsites in the boreal forest of Alberta. Songbird response to wellsite reclamation efforts in the boreal forest was previously unexamined, despite the abundance of wellsites,...

Use of Bioacoustic Technology to Evaluate Habitat Use and Road Effects on Two Anuran Amphibians in the Boreal Region of Northeastern Alberta
DownloadFall 2017
Habitat loss and fragmentation are thought to be leading causes behind local to global amphibian declines. Recent expansion of the energy sector in the western boreal forest of northeastern Alberta raises concerns for amphibians that occupy this landscape. Methods for monitoring anuran amphibians...

Use of Indices of Biological Integrity (IBIs) to assess wetland health in dry and wet conditions
DownloadSpring 2012
Indices of Biological Integrity (IBIs) estimate the biological condition of an ecosystem by measuring biological metrics that predict underlying environmental stress. I evaluated the use of IBIs developed from 5 biotic communities at 81 semi-permanent/permanent natural and constructed wetlands. ...
