Variability of the mtDNA Control Region in the Bean Goose, Anser fabalis Latham 1787, in the Russian Far East

The variability of the nucleotide sequences in the first domain of the mtDNA control region of Anser fabalis Latham 1787 was studied in 65 samples. A stable separation between A. f. serrirostris Swinhoe 1871 and A. f. middendorffii Severtzov 1873 was confirmed both on the phylogenetic tree and in the network of haplotypes. When comparing the sequences of A. fabalis studied earlier with those of the geese from Japan identified at the subspecies level, only one clustered with the A. f. middendorffii sequences. An assumption was made about the most likely pathways of spring migration of the geese wintering in Japan. Some geese from the Amur region were found to be similar to Anser cygnoides Linnaeus 1758.
