title: Electrophoretic and morphometric evidence for two species of the genus Rana (Amphibia, Ranidae) and some aspects of their variabilities.
abstract: Frogs of two species, genus Rana, R. mascareniensis and R. levantina from northern Egypt, were examined using electrophoresis for 15 presumptive loci and measuring of 11 morphological characters, employing discriminate and principle component analysis. Electrophoretic and morphometric data showed clear interspecific differences. Using serum and tissue electrophoresis all individuals of R. mascareniensis had no intraspecific variabilities but R. levantina showed some intraspecific variabilities.
