Abstract
The article presents data on genetic variability in populations of two brown frog species: the moor frog Rana arvalis and the siberian wood frog R. amurensis, in Western Siberia, Russia. Persentage of polymorphic ISSR-PCR-bands in R. arvalis was 63-93 %, in R. amurensis - 90 %, genetic diversity indices were 0.18-0.20 and 0.31, respectively. The high level of genetic variability in the siberian wood frog is contrary to its low population size, restricted distribution in the study area and the boundary position of the population. Some ISSR-PCR-bands were species-specific, they can be used for fast genotyping and further population genetic studies of the siberian wood and the moor frog in their areas of cohabitation.
Highlights
The article presents data on genetic variability in populations of two brown frog species: the moor frog Rana arvalis and the siberian wood frog R. amurensis, in Western Siberia, Russia
Moor frog is very widespread in Western Siberia, it can be found in many habitats, including anthropogenically transformed landscapes
We found a population of siberian wood frog in Uvatsky area where it dwell sympatrically with the moor frog
Summary
The article presents data on genetic variability in populations of two brown frog species: the moor frog Rana arvalis and the siberian wood frog R. amurensis, in Western Siberia, Russia. Some ISSR-PCR-bands were species-specific, they can be used for fast genotyping and further population genetic studies of the siberian wood and the moor frog in their areas of cohabitation. First data on genetic variability of the siberian wood frog rana amurensis in western siberia and its differentiation from the moor frog rana arvalis. The territory of Western Siberia was completely covered with ice during the Pleistocene It was colonized by the moor frog from the west, and by the siberian wood frog — from the east.
