Fig. 1 in A new vertebrate for Europe: the discovery of a range-restricted relict viper in the western Italian Alps

Fig. 1. Phylogenetic tree based on the Maximum-Likelihood reconstruction (calculated with PHYML v3.0; Guindon and Gascuel 2003) using 3254 bp of the mitochondrial DNA showing position of Vipera walser, and relationships with other Vipera species. Values of bootstrap supports are showed for neighbour joining (top left), maximum parsimony (top right), maximum-likelihood (bottom left) and Bayesian inferences (bottom right). Support values for the bPTP species delimitation model are shown in parenthesis right of the species epithet.
