The intra- and interspecific variability of the gene pools was assessed by applying vertical polyacrylamide gel electrophoresis on samples of blood, liver, skeletal and heart muscle. We compared the allelic variation of eight enzyme loci and of two non-enzymatic proteins among populations and species using the UPGMA-, Fitch-Margoliash- and maximum-likelihood-methods. The variability between conspecific populations was considerably smaller than the interspecific variability. Moreover, at the ADA locus alternatively fixed alleles were found in R. balcanica and R. ridibunda. Thus, the species status of the bioacoustically detected R. balcanica was confirmed.}, keywords = {KAPE Amphibia}, author = {Sofianidou, T.
