This week EEB welcomes Dr. Karen Samis from the Department of Biology, the University of Prince Edward island:
Expansion and introduction beyond geographic range limits
All species have limits to their geographic range, but there are numerous examples of species that have successfully moved beyond historical range limits. In recent decades a growing number of studies have experimentally demonstrated that ecological aspects of climate gradients (latitude, continentality, elevation) are associated with variation in growth and fitness across geographic ranges, but fewer of these studies occur at or beyond range limits. In light of current global ecological threats including climate change and biological invasions, there is a pressing need to refine our ability to predict organismal phenotypic responses at the edge of species’ geographical ranges. In this talk, I will present data from experiments with native and non-native species transplanted at and beyond their geographical range limits in an effort to understand the genetic and ecological factors that limit ranges and enable range expansion.
The EEB Seminars run weekly, on Thursdays, in the EEB Lounge of the BioSciences Complex, Room 4338, from 12:30-1:30pm. Light refreshments are served starting at 12:15.
