Evolutionary quantitative genetics and genomics applied to the study of sexually dimorphic traits in wild bighorn sheep (Ovis canadensis)Download
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,...
Previous studies of the grey wolf (Canis lupus) using microsatellites have showed strong population structure despite the high mobility of individuals. I re-assessed the structure of North American grey wolves by genotyping 132 wolves at a genome-wide set of >26 000 single nucleotide...
Genetic diversity and selection in North American red squirrels (Tamiasciurus hudsonicus): A Hamiltonian perspective into the processes and mechanisms of evolutionDownload
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...
A molecular assessment of range expansion of the northern or virile crayfish (Orconectes virilis), crayfish-based community co-structure, and phylogeny of crayfish-affiliated symbiontsDownload
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...
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...
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...
On the evolutionary history and population genetic structure of the North American mountain goat (Oreamnos americanus)Download
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...
