Gene Flow

Gene Flow

(p.109) Chapter 5 Gene Flow
Eco-evolutionary Dynamics

Andrew P. Hendry

Princeton University Press

This chapter looks at empirical methods for quantifying gene flow and inferring its role in adaptive divergence. An important point made therein is that gene flow can sometimes aid adaptation, such as when it enhances the genetic variation on which selection acts. The key questions addressed with empirical data are divided into the potential negative versus positive effects. On the negative side, questions include to what extent gene flow constrains adaptive divergence among environments, and how the resulting maladaptation might cause population declines and limit species' ranges. On the positive side, questions include whether gene flow has a special benefit in the case of antagonistic coevolution, and whether it can save (rescue) populations that would otherwise go extinct.

Keywords:   gene flow, adaptive divergence, adaptation, genetic variation, maladaptation, antagonist coevolution, extinction
