About population variability of bean goose ( Anser fabalis) at the migration over distribution in the south of Russia

In the paper, an ecomorphism, a geographic variability and population origin of bean gooses during their migration in the South of Russia are discussed. A few genetic features of the bean goose populations were considered. On the basis of analysis of nucleotide sequences of mitochondrial DNA (mtDNA) haplotypes the authors estimated the genetic differentiation in forms (subspecies) of bean goose. The problems of conservation of the bean goose species in whole, and a methodological validity of regulation of goose hunting are under consideration.
