Tuesday "Noon" Seminar: Feb. 6, 2006

12:30-1:45 p.m. in Biosciences West (map of building location), Room 208

Hanna leads the Lab of Ecological and Evolutionary Dynamics. Her interests range from sexual selection, sex roles and spatial behavior to the theory of sustainable exploitation of natural resources. Some of her recent publications are listed below. For more information visit Hanna’s webpage, or read her profile published in Science.

Hanna will be available to meet with people on Monday, February 5 and Tuesday, February 6. Please see the sign-up sheet in the EEB Office, BSW 310 or email Joanna Rutkowska at jrutkows@email.arizona.edu.

Talk Abstract

I will present results on both "love" (sexual selection) and "hatred" (territorial conflict). In both cases I will investigate the role of "feedback," that is, ask the question how strongly individual behaviour influences population dynamics, which then feeds back to influence what is adaptive at the individual level. We know that selection does not favour what is good for a group (or species), but do we ask often enough how "bad" it can get? For example, are sexually selected species expected to be particularly prone to extinction? And, does territoriality in the Seychelles magpie robin - a species that recently got its status downlisted from critically endangered to endangered - increase its vulnerability to environmental change?
