Anna Hargreaves Aloe arborescens pollination ecology evolution research

Welcome to the Hargreaves lab in the Department of Biology at McGill University. Our research straddles ecology and evolution, broadly focusing on interactions among species (biotic interactions) and the dynamics of species range limits.  Much of our research is field-based; using large- and small-scale experiments in natural environments to test and refine theoretical ideas in ecology and evolution that have practical conservation relevance.  We are especially interested in adaptation in range-edge populations, interactions among flowers and their visitors, and the role biotic interactions play in shaping species’ geographic distributions.

In addition to research, the lab deeply values science education.  One of our on-going goals is to conduct outreach that helps improve public scientific literacy and foster an appreciation for the beautiful complexity of the natural world.
