Professor to discuss gender determination of turtles at Science Cafe


Department of Biological Sciences Professor Willem Roosenburg will lead the first Science Café discussion of spring quarter at 5 p.m. Wednesday, April 4, at the Baker University Center Front Room.

Roosenburg will be presenting "Turtles: Why Girls are Hot and Boys are Cool." This discussion will focus on the relationship between temperature and the sexual determination of diamondback terrapin turtles. Roosenburg has conducted his research through the analysis of more than 15,000 turtles from the Chesapeake Bay area.

"We ask how temperature impacts sex ratios, its consequences on population and how global warming might affect these ratios," said Roosenburg.

Roosenburg's areas of specialization include evolution of life histories and population dynamics of vertebrates. He is a founding member of Diamondback Terrapin Working Group, a group dedicated to the conservation, restoration and study of terrapins.

Science Cafés are free venues for students interested in the sciences and engineering to informally share their interests during a conversational exchange with faculty, staff and the community in a friendly setting.
