| Περίληψη: | The water frogs of the genus Pelophylax are of the most diverse and widespread amphibians in mainland and island Greece, consisting of six species often with overlapping distributions. While the genus ecology has been extensively studied, we still known surprisingly little regarding species’ genetic structure, especially in regions of contact zone, were cases of hybridization have been reported. Here, we used 12 nuclear markers to examine the genetic diversity and differentiation between Pelophylax populations and investigate the existence of hybrids. We focused on ten mainland populations of P. epeiroticus, P. kurtmuelleri, P. ridibundus and P. bedriagae distributed throughout Greece. We performed a Bayesian clustering analysis with STRUCTURE and multivariate statistics (PCA, DAPC) to identify the genetic structure of the Pelophylax populations. We then used HYBRIDLAB to simulate genotypes corresponding to individuals of explicit ancestry categories: pure parental populations, first-generation (F1) crosses, second-generation (F2) crosses, and backcrosses. With these new genotypes added into our dataset, we assign ancestry using discriminant analysis of principal components (DAPC). Our findings revealed clear genetic differentiation between populations and species with high levels of genetic diversity. On top of that, we were able to identify samples of admixed ancestry implying the existence of viable hybrids between Pelophylax species. |
