Ecology, Evolution & Conservation Biology

How does biodiversity form and why does it vary over space and time? We are fascinated by this question and explore it with a focus on closely related species – a key step in the formation of biodiversity. We study how closely related species interact to influence each other's behaviours, ecologies, and evolution, and how these interactions, and organisms in general, are shaped by geographic variation in selective pressures. Our work extends to how interactions among species mediate human impacts on diversity such as urbanization, climate change, and the introduction of non-native species. We often study birds, but increasingly conduct research on insects. You can find us in the Biology Department at Queen's University in Kingston, Ontario, Canada.
