Climate Change, Evolution and Conservation
February 10, 2014
Speaker: John J. Wiens, Professor, Department of Ecology and Evolutionary Biology, University of Arizona, Tucson, AZ
This seminar focuses on how species respond to climate change. Each species has a niche, a range of temperature and precipitation conditions within which it operates. If climate change causes these conditions to shift outside the climatic niche of a species, then populations must either move, acclimate behaviorally or physiologically, or adapt evolutionarily and shift their climatic niche. Otherwise, the species may go extinct. The discussion will expand on two key issues: (a) how quickly do climatic niches evolve relative to the projected pace of future climate change? (b) what causes species and populations to go extinct as climate changes?
