Integrative Behavioural Ecology of Mating

Maydianne CB Andrade
Professor & Canada Research Chair

 We examine how reciprocal effects of ecological and social factors influence 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).
