Dr. Megan Bontrager Department of Ecology & Evolutionary Biology at University of Toronto Local adaptation at range edges and under anomalous climates Species’ geographic ranges are limited on the landscape. A major focus of work in the Bontrager lab is identifying which evolutionary and ecological forces interact to shape species’ geographic distributions and limit adaptation. In addition, populations are frequently adapted to their local environments, and my lab works to identify which components of the environment are the most important factors driving local adaptation. I will talk about how gene flow affects range edge populations and how these effects may be especially important under climate change. I will also present results from two quantitative syntheses of transplant experiments to 1) examine how climate change is altering patterns of local adaptation, 2) evaluate the relative importance of temperature and precipitation to local adaptation and 3) examine how the magnitude of local adaptation changes from range centres to range edges. This work explores critical drivers of plant population performance and characterizes patterns of adaptation across species' ranges.
