MSc thesis

Human modification of the environment, including large-scale habitat conversion and soaring greenhouse gas emissions, pose major threats to global biological diversity. Maintaining species’ ability to persist in changing environments ultimately means preserving genetic variation underlying ecologically important traits. Work in our lab is at the interface of ecology and evolution, investigating the genetics of adaptation, life history variation, speciation, population history and phylogeography. Projects feature organisms spanning a wide taxonomic breadth, including freshwater fish and wildlife species of varying conservation status, and are geared towards addressing issues of immediate local, regional and global concern.


Lab people


Oct. 2020:  A new paper published in Biological Invasions employs population genomics to infer geographic origins and timing of brown rat invasions of the Haida Gwaii archipelago to inform biosecurity efforts.          

Aug. 2020: A new paper published in Molecular Phylogenetics & Evolution employs phylogenomics to reveal novel relationships among Neotropical crocodiles.

July 2020: Congratulations to Brock Burgess for advancing to candidacy. A new paper published in Ecology & Evolution investigates the role of glacial history in shaping patterns of population genetic variation in American badgers, with implications for conservation.

June 2020: A new paper published in PLOS ONE demonstrates the utility of GT-seq as a rapid response tool for informing invasive species management.    

May 2020: A new paper featured on the cover of Ecology & Evolution finds marked population structure in Western Rattlesnakes to inform their conservation status at the northern range margin.

Feb. 2020: A new paper published in CJFAS combines population genomics and otolith microchemistry analyses to reveal kokanee–sockeye salmon hybridization leads to intermediate morphology and resident life history, with important implications for fisheries management.
