Integrative Behavioural Ecology of Mating

We examine how reciprocal effects of ecological and social factors affect reproductive tactics, life history decisions, physiological performance, and sexual selection. One recent focus is exploring how these processes shape divergence in phenotypic traits related to mating in geographically separated populations.

Our work includes laboratory and field studies of invertebrates, and our primary study organisms are the black widow spiders (genus Latrodectus).

We are members of:

· Integrative Behaviour & Neuroscience Group

· Department of Biological Sciences

· Graduate Department of Ecology & Evolutionary Biology
