*congratulations to Lucy, Hosay, and Nizanthan on their first paper—this was based on data they collected as undergraduates during a collaborative research course (BIOC99)
· Welcome to collaborator Dr. Ally Harari who is visiting from the Volcani Centre (Israel) and giving a departmental seminar: Male choice and costly sexual signals in moths
· Farewell to Leo Castilho, who is returning to the University of Brasilia after a very successful term in the lab as a visiting graduate student.
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).
