Fig. 2 in Phylogeography of the Ibero-Maghrebian red-eyed grass snake (Natrix astreptophora)
Fig. 2 Mitochondrial phylogeny of all three grass snake species inferred from Maximum Likelihood using 1984-bp mtDNA (ND4+tRNAs, cyt b). Terminal clades collapsed to cartoons. Outgroups (Natrix maura, N. tessellata, Nerodia sipedon) removed for clarity. Numbers along nodes indicate branch support under Maximum Likelihood (1000 bootstrap replicates) and Bayesian Inference (posterior probabilities). Asterisks indicate maximum support under both tree-building methods. For Natrix helvetica and N. natrix, clade names correspond to Kindler et al. (2013).
