Summary results of the Bayesian clustering assignment implemented in Structure, with colours indicating clusters, or populations. (a) Number of K clusters best explaining genetic data of the six Pelobates cultripes populations from two different regions of the Iberian Peninsula, central and southern Spain. (b) Separated analysis for central region. Optimal number of clusters was K = 2 (upper panel), closely followed by K = 3 (lower panel). (c) Separated analysis for southern region.
