Recherche

Rapid environmental change has been shown to result in elevated extinction rates and thus poses a significant threat to Canadian biodiversity. By using manipulative field experiments to connect fitness-related traits with underlying genetic architecture in relevant ecological scenarios, my research program investigates the evolutionary capabilities of natural populations to adapt to changing environments. My long-term goal is to address several basic questions about the genetics of adaptation that would aid our ability to generate predictive models of evolutionary change; these include but are not limited to: 1) How strong is natural selection on phenotypes, and how does this selection “filter down” to the genetic level? 2) How are regions affected by selection distributed throughout the genome? 3) What are the causal agents of natural selection? 4) What are the mechanisms underlying population responses to environmental change? There is theory addressing several of these questions, but we have few empirical tests in nature. Using two key study systems (stickleback fish and deer mice), my research program combines field-based selection experiments with molecular and computational biology to focus on two key areas: adaptation to changing environments and experimental genomics. The strength of this research program for enabling predictions about how biological systems will respond to environmental change lies in its interdisciplinary nature, integrating methods and knowledge from ecology, evolution and genomics. Solving climate change related problems such as species extinctions, invasive species, and the environmental health of society depends directly on the intersections between these disciplines of biology.
