Figure 4From: Does a shift in host plants trigger speciation in the Alpine leaf beetle Oreina speciosissima(Coleoptera, Chrysomelidae)?Geographical distribution of the 13 sampled populations of Oreina speciosissima and results from AFLP Bayesian clustering. Populations are labeled according to morphotype (i.e. square - Oreina speciosissima sensu stricto, circle - Oreina speciosissima troglodytes and polygon - intermediate forms) and clusters defined using the Bayesian model-based STRUCTURE algorithm (i.e. colors of tips according to K = 5 groups). Grey shaded areas represent elevated regions with altitudes above 1000 m. For full names of the populations see Table 1.Back to article page
