Sampling localities, sample sizes, and summary of genetic data.

Pop # refers to population number as indicated in Figure 1; N indicates the sample size for each species and population, bp the number of base pairs used after removal of sites with missing or ambiguous characters in at least one of the sequences (see Materials and Methods), h the number of haplotypes, #Mut the number of mutations, S the number of polymorphic sites, Hd the haplotype diversity, π the nucleotide diversity, k the mean number of pairwise differences between sequences. Hd, π, and k has been calculated only for populations with two or more individuals. Populations are indicated with the municipality name first followed by the population name. “*” next to the population names indicates that animals were sampled in old quarries, outside caves or deeply buried under stones. No “*” indicates that populations were sampled in caves.
