Examining Associations of Community Food Environments with Individual Diet Quality and Body Weight Status of Canadian Children
DownloadFall 2019
Reducing the prevalence of unhealthy eating is an important challenge to address in order to reduce the burden of obesity and chronic disease. Approximately 1.6 million or one-third of Canadian children and youth are overweight or obese, and about 70% of children and youth consume less than five...

Factors affecting larval growth and development of the boreal chorus frog Pseudacris maculata
DownloadFall 2010
The boreal chorus frog (Pseudacris maculata) is a widespread species but we know little of its ecology. I examined the nature and existence of competitive mechanisms operating between larvae of the boreal chorus frog and wood frog (Lithobates sylvaticus) from field, mesocosm and laboratory venues...

Specialist predators with a limited diet may be less adaptable to environmental change than generalists, which consume a diversity of prey. As the climate changes, ecological homogenization is occurring, where generalist species outcompete specialists, reducing ecosystem complexity. In Arctic...

Industrial development is transforming Alberta's landscapes, with largely unquantified effects on wildlife species. Open-pit mining is occurring on vast expanses, most notably for bitumen but also extensively for coal in a rich seam that traverses the province. Major concerns have developed over...

Background: Unhealthy diet is a well-established risk factor for developing many physical health conditions in adolescents (e.g., obesity, type 2 diabetes). Evidence begins to emerge that unhealthy diet might also be implicated in the development of common mental disorders. While there is a...

Investigation of fatty acid and cholesterol synthesis using stable isotopes in type 1 diabetes, liver failure, islet and liver transplant, and effect of dietary intervention
DownloadSpring 2011
Elevated plasma lipids are risk factors for cardiovascular disease (CVD). In certain conditions plasma lipids are normal yet individuals experience increased morbidity. Type 1 diabetes (T1D) is associated with elevated CVD despite normal lipids, while in liver failure low plasma lipids may...

Isotope Geochemistry of Natural Gas from the Horn River Basin: Understanding Gas Origin, Storage and Transport in an Unconventional Shale Play
DownloadFall 2014
Devonian shales of the Horn River Basin, northeast British Columbia are recognized key targets for unconventional shale gas production in Canada. Recent studies show gas isotope geochemistry in several unconventional shale plays worldwide differ from conventional hydrocarbon reservoirs and carbon...

Local and regional demography in a migratory forest songbird and effects of forest management intensity
DownloadSpring 2014
The numerical response of forest birds to habitat alteration has been well documented in North America, but the underlying demographic processes driving these changes remain largely unknown. Among species sensitive to such alterations, the Ovenbird (Seiurus aurocapilla) shows one of the largest...

Background: Vitamin A status is an important health determinant. Deficiency of this micronutrient is a serious global health issue in the developing nations as the leading cause of preventable blindness in children and is a significant contributor to long-term morbidity and mortality. Nutritional...

Surface mining for bitumen extraction results in production of tailings that are deposited into large ponds. Tailings in the ponds support diverse microbial communities capable of metabolizing organic compounds and producing biogenic gases (methane, CH4 and carbon dioxide, CO2). Because of low...
