Data from: Population genetic analyses using 10 new polymorphic microsatellite loci confirms genetic subdivision within the olm, Proteus anguinus

We provide a comparative population genetic study of the elusive
amphibian, Proteus anguinus, by comparing the genetic diversity and
divergence among four cave populations (96 individuals) sampled in the
Dinaric Karst of Croatia. We developed 10 variable microsatellite markers
using pyrosequencing and applied them to the four selected populations
belonging to four different cave systems. The results showed strong
genetic differentiation between the four caves corroborating with previous
findings suggesting that Proteus might comprises several unrecognized
taxa. Our results confirmed that gene flow should be high within the
caves, whereas it is low between hydrographic systems since geological
periods. Finally, we conclude that the high genetic subdivision suggests
the necessity of treating the four studied Proteus populations as
evolutionary significant units.
