Figure 1 in An extended mtDNA phylogeography for the alpine newt illuminates the provenance of introduced populations

Figure 1. Distribution map for the alpine newt (Ichthyosaura alpestris). Background colour reflects the rough natural distribution of the mtDNA clades and symbols reflect sampled localities. The inset shows the Netherlands in more detail (lighter shading reflects uncertainty about the status of populations in the northeast of the country). Numbers refer to localities/regions mentioned in the text: 1 = Oudeland, 2 = Veluwe and 3 = Holterberg. Sampling information in supplementary table S1.
