Genetic homogeneity in a Pontocaspian crested newt species (Triturus karelinii) suggests recent isolation of its three allopatric range sections

What is it about?

The southern crested newt (Triturus karelinii) has a peculiar distribution with three geographically isolated range sections (Crimean, Caucasian and Caspian). We show there is very little genetic divergence between these range sections, suggesting their isolation was attained only recently.
