Ecological and evolutionary responses to rapid environmental change
Most of our work in this area focuses on urban ecology and evolution. Cities alter dramatically alter selection pressures and population demography through wholesale habitat change and fragmentation. We study ecology and evolution in cities with synthetic multi-species data analyses and using our focal study population of urban red and grey squirrels here in Winnipeg.
Evolutionary and ecological consequences of climate change related range shifts
Climate change is altering species ranges as populations move in an attempt to track climate to which they are suited. This is a general pattern and we are exploring its consequences in terms of altered predation patterns (killer whales and narwhals), ecosystem change (salmon moving into the Arctic), and secondary contact between recently diverged species (flying squirrel hybridization).
Evolution in invasive species
Invasive species damage ecosystems and understanding evolutionary change in invasive populations can help guide their management. We study the demography, selection, sex determination, and responses to pesticide application in native populations of sea lamprey in the Atlantic and in invasive freshwater populations in the Great Lakes.
