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...

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,...

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...

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...

On the evolutionary history and population genetic structure of the North American mountain goat (Oreamnos americanus)
DownloadSpring 2012
The spatiotemporal scale at which genetic diversity is assessed can provide insights into both broad- and fine-scale patterns in ecology and evolution. I examined the distribution of genetic diversity and the evolutionary history of the North American mountain goat (Oreamnos americanus). I first...

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...

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...

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...
