title: [Biochemical variability and genetic differentiation of marsh frog Rana ridibunda Pall. populations].
abstract: Marsh frog populations of Rana ridibunda s. lato from the Ukraine, Caucasus, Turkmenistan and Tadzhikistan have been analyzed genetically by 31 isozyme gene loci. The genetic distance between populations from Tadzhikistan on the one hand, and other regions, on the other hand is D-0.269, that assumes evolutionary divergence at the species level. The presence of fixed allelic substitutions between two populations from Tadzhikistan by five gene loci (Aat-S, Ldh-B, Alb, Es-5) supposes genetic heterogeneity of species in this region. Peculiarities of allozyme variation of this species are discussed.
