Figure 4

The geographical distribution of genetic variation for the different Triturus species. These are composite maps for all nine Triturus species. For each species, the genetic variation within each population (π) was determined and subsequently interpolated across its distribution range. In Figure 4a we use a single scale for all Triturus species (allowing direct comparison among species) whereas in Figure 4b we use a species specific scale (better expressing genetic structure in genetically relatively poor species). Warmer colors refer to a higher genetic diversity. The insets show the situation for T. cristatus (left) and T. marmoratus (right) in their area of sympatry (shown in dark gray on the main maps).
