How does this affect how quickly they can adapt, and what kinds of patterns of neutral genetic diversity do we expect? We find that spatial structure creates a large gap in adaptibility between populations which are totally asexual and those that occasionally recombine. We also find that adaptation creates a kind of effective long-range dispersal, increases relatedness between spatially distant individuals.   Resnick (Bldg. 209) 2nd floor seminar room המחלקה לפיזיקה physics.dept@mail.biu.ac.il Asia/Jerusalem public

Abstract

Most populations are spread over spatial ranges that are far larger than individuals typically disperse. How does this affect how quickly they can adapt, and what kinds of patterns of neutral genetic diversity do we expect? We find that spatial structure creates a large gap in adaptibility between populations which are totally asexual and those that occasionally recombine. We also find that adaptation creates a kind of effective long-range dispersal, increases relatedness between spatially distant individuals.
