Does variation in selection imposed by bears drive divergence among populations in the size and shape of sockeye salmon?

Evolution; international journal of organic evolution - 1 May 2009

Carlson Stephanie M, Rich Harry B, Quinn Thomas P

Abstract excerpt

Few studies have determined whether formal estimates of selection explain patterns of trait divergence among populations, yet this is one approach for evaluating whether the populations are in equilibria. If adaptive divergence is complete, directional selection should be absent and stabilizing selection should prevail. We estimated natural selection, due to bear predation, acting on the body size and shape of...
