Abstract

Natural hybridization and introgression is recorded between the newt species Triturus vulgaris and T. montandoni in Slovakia. To confirm a hybrid status of two putative hybrids, morphological and Randomly Amplified Polymorphic DNA (RAPD) markers specific for T. vulgaris and T. montandoni were used. The individuals found in Zbojská (Veporské vrchy Mts, Slovakia; analyzed morphologically and genetically) and Zubrohlava (Oravská kotlina basin, Slovakia; analyzed only morphologically) possessed markers of both species. Segregation of RAPD markers together with a model-based Bayesian analysis revealed that the specimen from Zbojská belonged to later generation hybrids.
