Maps showing the Triturus localities used for the mitochondrial DNA phylogeography and species distribution modeling. The inset shows part of the localities used in the genetic analyses (white circles) and the additional ones used for species distribution modeling (black circles). Two cut-outs (A and B) show more details on introgressed mitochondrial DNA: populations containing foreign mitochondrial DNA are labeled with a colored star (with the color denoting the ‘donor’ species) and populations containing two mitochondrial DNA types (of which one mostly, but not exclusively, is of the original species) as a black star; populations containing original mitochondrial DNA are again labeled with white circles. The colors used correspond to Figure 1. Details on localities can be found in Dataset S1 and S2.
