Fig. 1From: Contrasting evolutionary histories of the legless lizards slow worms (Anguis) shaped by the topography of the Balkan PeninsulaMaximum likelihood (ML) phylogenetic tree of Anguis species and their distributions in the Balkans based on a fragment of mtDNA (ND2). Anguis veronensis (in white) occurs outside the area studied here. Numbers at nodes show Bayesian posterior probabilities and ML bootstrap support values. Yellow lines denote contact zones between two species. Numbers correspond to the locality numbers as given in Additional file 1: Table S1Back to article page
