Postglacial recolonization in a cold climate specialist in western Europe: patterns of genetic diversity in the adder ( Vipera berus) support the central–marginal hypothesis
Abstract Understanding the impact of postglacial recolonization on genetic diversity is essential in explaining current patterns of genetic variation. The central–marginal hypothesis ( CMH ) predicts a reduction in genetic diversity from the core of the distribution to peripheral populations, as wel...

Abstract Understanding the impact of postglacial recolonization on genetic diversity is essential in explaining current patterns of genetic variation. The central–marginal hypothesis ( CMH ) predicts a reduction in genetic diversity from the core of the distribution to peripheral populations, as well as reduced connectivity between peripheral populations. While the CMH has received considerable empirical support, its broad applicability is still debated and alternative hypotheses predict different spatial patterns of genetic diversity. Using microsatellite markers, we analysed the genetic diversity of the adder ( V ipera berus ) in western Europe to reconstruct postglacial recolonization. Approximate Bayesian Computation ( ABC ) analyses suggested a postglacial recolonization from two routes: a western route from the Atlantic Coast up to Belgium and a central route from the Massif Central to the Alps.
