Figure 5.

The predicted distribution forTriturus macedonicusandT. kareliniiunder current and Last Glacial Maximum conditions based on ecological niche modeling. The ecological niche models projected on current, mid-Holocene (~6Ka) and Last Glacial Maximum (~21Ka) climate layers for T. macedonicus are shown on the left (a, c, e) and those for T. karelinii on the right (b, d, f). The warmer a grid cell’s color, the higher its predicted suitability. The current range of T. karelinii is outlined in blue and that of T. macedonicus in green, with the zone of asymmetric mitochondrial DNA introgression outlined in red.
