Dylan Fraser (Principal Investigator) I wake up every morning and study fish, so life is good! More generally, I’m fascinated with the population diversity that is found within virtually any species: (i) how does such diversity arise? (ii) How does the evolution of population diversity affect species’ responses to environmental change? (iii) Will small populations adapt as human activities shrink habitats and species abundances? 

Dr. Deliang Li (Visiting Prof 2016-present)
I am an associate professor at Hunan Agricultural University, Hunan Province, China and a visiting scholar in the Fraser lab from April 2016 to March 2017. My work focuses on fishery resources and the environment in the Dongting Lake basin (the second largest lake in China). My main interests including 1) the evaluation and conservation of fishery resources and 2) the effects of anthropogenic disturbances (heavy metals, hydroelectric projects, aquaculture, etc.) on natural fishery resources and the related underlying mechanisms. In the Fraser lab, I am expanding my knowledge concerning fish population genetics.

Dr. Ella Bowles (Postdoctoral Fellow 2016-present)
Collaborative population monitoring integrating scientific and traditional knowledge is integral to community-based population management. The Cree Nation of Mistissini, QC, have been collaborating to manage walleye (Sander vitreus) populations in Mistassini Lake. Life history and genomic attributes of walleye populations were compared between 2002/2003 and 2015, between which local population size and fishing-based tourism increased, in four rivers (southern: 1-3; northern: 1). Contemporary reductions in both length (11 to 21%) and mass (24 to 39%) have occurred in the southern rivers, near the only human settlement on the lake, but not in the northern. I am working to determine whether genomic estimates of population size and genetic diversity track changes in life history. Management and monitoring plans for these populations have been undertaken that are complementary to traditional customs and fishing techniques, showing leadership towards maintaining aquatic biodiversity.

Elizabeth LawrenceElizabeth Lawrence (PhD 2014-present)  (Concordia Natural Sciences and Engineering Research Scholar) I am currently assessing vertebrate population diversity across the Americas by constructing a database of population level measures of genetic diversity based on microsatellite DNA. This will ultimately allow me to compare three levels of biodiversity: genetic, population, and species. By applying species-area curve theory to this data, I will assess latitudinal patterns across vertebrate groups as well as anthropogenic influences on biodiversity at each of the three levels.

DSC03671Andrew Harbicht (PhD 2013-present)Adaptive management in species restoration: Atlantic salmon in Lake Champlain (in collaboration with the US Fish & Wildlife Service; Concordia PhD Fellowship). I am currently working with our partners south of the border to assess several aspects of an Atlantic salmon reintroduction program in Lake Champlain. More specifically, I am looking into how changes to management practices can impact the likelihood of salmon establishing themselves. I am also addressing the impact of a vitamin B1  deficiency (due to a dietary shift towards introduced alewife) on salmon migratory capabilities. Our goal with this project is to address questions directly applicable to Atlantic salmon in Lake Champlain, but using novel approaches (telemetric, genetic) that will permit our results to be widely applicable to species reintroduction.
