Evolutionary quantitative genetics and genomics applied to the study of sexually dimorphic traits in wild bighorn sheep (Ovis canadensis)
DownloadSpring 2011
The independent evolution of the sexes may often be constrained if male and female homologous traits share a similar genetic architecture. Thus, cross-sex genetic covariance is assumed to play a key role in the evolution of sexual dimorphism (SD) with consequent impacts on sexual selection,...

Investigating the genetic basis of boldness and reproductive performance traits in the grey seal (Halichoerus grypus)
DownloadSpring 2022
Individual variation provides the material for natural selection to act upon, influencing ecological and evolutionary processes. Much phenotypic variation in traits, such as behaviour and life-history, have a moderate to high heritable component, suggesting that these traits may have adaptive...

Headgear are cranial appendages usually seen in males of infraorder Pecora. This trait is used to determine hierarchy and gain access to mates. In bighorn sheep, males or rams have impressively large horns that are made of keratin and cancellous bone. These horns are used in yearly combats to...

A molecular assessment of range expansion of the northern or virile crayfish (Orconectes virilis), crayfish-based community co-structure, and phylogeny of crayfish-affiliated symbionts
DownloadFall 2012
Geographical limits of a species’ range are determined in part by the environmental tolerances of that species, and also by its past and current ability to colonize new areas. Range shifts are a common occurrence in the evolutionary history of almost all taxa; however, anthropogenically-mediated...

Evaluating the Extent of Hybridization between Mule and White-tailed Deer in Western Canada
DownloadSpring 2020
Mule deer (Odocoileus hemionus) are endemic to a wide variety of habitats in western North America, many of which are shared in sympatry with their closely related sister-species white-tailed deer (O. virginianus). Hybridization of mule and white-tailed deer has historically been observed on a...

Genetic diversity and selection in North American red squirrels (Tamiasciurus hudsonicus): A Hamiltonian perspective into the processes and mechanisms of evolution
DownloadFall 2013
The theory of natural selection has advanced our understanding in every aspect of biological sciences, yet despite this seeming ubiquity, there remain some components that are not fully resolved. Natural selection predicts the “selfish” advancement of genes that are optimally suited for their...

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...

Polar bears (Ursus maritimus) were among the first large mammals to be assessed for genetic variation in the wild, and they remain a common subject of genetics studies. Although recent advances in genotyping technology have allowed for more accurate determination of population structure and the...

Fall 2015
Since the mid-2000’s there has been a major shift in molecular ecology to the use of genomic methodologies. These methods utilize genome-wide sampling of genetic variation and allow for consideration of questions that cannot be answered with a handful of microsatellite markers or a few gene...
