Figure 3From: Tracing glacial refugia of Triturus newts based on mitochondrial DNA phylogeography and species distribution modelingA Neighbor Joining phylogeny for the Triturus ND4 haplotypes. The Triturus haplotypes cluster into nine monophyletic mitochondrial DNA lineages, corresponding to species and colored as in Figure 1. Significantly supported branches (≥ 80%, based on a thousand bootstrap replicates) are denoted with an asterisk. The Calotriton asper outgroup used to root the phylogeny is not shown.Back to article page
