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).

Congratulations to Ramanja Pakirathan, Archchana Rajmohan, Danielle Alvares, Imaan Javeed, and Kishon Thaveswaran for doing the lab proud while presenting their work at the OE3C 2016 conference this weekend.

Special kudos to Ramanja, who was awarded an honourable mention in the undergraduate talk competition!

Bon voyage 2: Nishant is on his way to his first field season at Berkeley’s Hastings reserve (California, May-June)

Bon voyage 1: Catherine is spending an epic 6 month field season studying western widows at Island View Beach*, British Columbia (April – September). See great photos by Dr. Sean McCann

Welcome back to Monica who just completed a successful field trip to Sydney, Australia where she studied redbacks while hosted in the lab of Dr. Michael Kasumovic.

*our thanks to the Tsawout First Nation for giving us permission to do our research on their lands.
