Cryptic barriers to dispersal within a lake allow genetic differentiation of Eurasian perch.

Evolution; international journal of organic evolution - 1 Aug 2007

Bergek S, Björklund M

Abstract excerpt

Gene flow between coexisting or nearby populations normally prevents genetic divergence and local adaptation. Despite this, there are an increasing number of reports of sympatric sister taxa, indicating potential divergence and speciation in the face of gene flow. A large number of such reported cases involve lake-dwelling fish, which are expected to run into few physical barriers to dispersal within their...
