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...

Longitudinal and cross-sectional associations between physical activity, screen time, and fitness in a sample of young children from Edmonton, Canada
DownloadFall 2016
Background: High fitness is associated with several positive health outcomes; however, fitness of Canadian children has declined over the past two decades. Correlates of fitness in children under 10 years of age are relatively unexplored, and few studies involving young children have looked at...

Population-level responses of fathead minnow (Pimephales promelas) to alarm substances and predator odour
DownloadSpring 2010
Alarm substances, released by injured prey, and odours from predators, such as northern pike, are chemical cues associated with increased predation risk in aquatic ecosystems. In laboratory studies, individual prey can respond to the presence of such cues by reducing conspicuous behaviours, such...

Resources and Reproductive Trade-offs Affect Fitness, Life History Traits, and Sexual Selection in Red Squirrels
DownloadSpring 2017
Animals face trade-offs throughout life between competing functions, such as between self-maintenance, reproduction, and survival. Resource allocation between these competing functions leads to different patterns of life history traits, changes in investment in reproductive effort, and different...

Rising from the ashes; an unanticipated failure with the engorgement factor voraxin leads to advances in three areas of tick biology: Developmental abnormalities and parthenogenesis, identification of a Coxiella-like symbiont and the molecular characterization of vitellogenesis in the southern African bont tick, Amblyomma hebraeum Koch (1844)
DownloadFall 2012
Weiss and Kaufman (2004, PNAS 101: 5874-5879) demonstrated that injections of fed male gonad homogenates stimulate engorgement in virgin female Amblyomma hebraeum ticks, due to the presence of the engorgement factor voraxin. They also showed voraxin's potential as part of an anti-tick vaccine:...

Background and Objective High-fat Western diets have been linked to the dysregulation of fatty acids (FA) and glucose intake in tissues, resulting in adverse metabolic outcomes such as obesity, insulin resistance, and atherosclerosis. There is a pressing need for new therapeutic approaches to...

Fall 2017
Phosphatidylethanolamine N-methyltransferase (PEMT) is a hepatic enzyme that converts phosphatidylethanolamine to phosphatidylcholine. Pemt-/- mice are protected from obesity and insulin resistance, a phenotype that is reversed with dietary choline supplementation. Additionally, PEMT deficiency...

Spring 2023
Atherosclerosis and aortic aneurysms are two major vascular diseases, and extracellular matrix (ECM) plays an important role in both as a non-cellular component of the aortic wall that also regulates vascular cell behavior and function. Atherosclerosis is a major contributor to cardiovascular...

Seasonal phenology and reproductive behaviour of Dioryctria species Zeller (Lepidoptera: Pyralidae) in British Columbian seed orchards
DownloadSpring 2011
Seasonal phenology and mating frequency of moths in the genus Dioryctria found sympatrically in north Okanagan Valley, British Columbia seed orchards were assessed. Female moths in the abietella, auranticella, ponderosae and schuetzeella species groups were trapped in Douglas-fir, lodgepole pine...

Spring 2013
Early embryonic development is a dynamic period that requires precise and timely interaction between the developing embryo and the maternal environment. A series of studies were carried out in order to identify the vital components of this environment and to understand their temporal and spatial...
