THE CURRENT STATUS OF CHROMOSOMAL INVESTIGATIONS OF BATS (CHIROPTERA) FROM THE RUSSIAN FAR EAST

A review of available karyological data on bats from the Russian Far East is presented. Karyotypes of eight species out of 18 species of bats from the Russian Far East have not been investigated yet. The chromosomal data on seven species (Myotis bombinus, M. frater, Plecotus sacrimontis, Barbastella darjelingensis, Pipistrellus abramus, Murina ussuriensis, and Miniopterus fuliginosus) among these ones are known from some other geographical regions. A chromosomal set for Myotis gracilis is still unknown. The differences found in the number of large pairs of metacentric chromosomes in Murina hilgendorfi from different geographic populations attest that two species, M. hilgendoifi and M. leucogaster inhabit the Russian Far East. The interspecies differences in the number and location of NOR among the chromosomes of Myotis species can be used for the solution of taxonomic problems. For bats from the Russian Far East, the NOR was described only for Plecotus ognevi and Eptesicus nilssoni. Further investigations of bats from the Russian Far East can help to detect their karyological peculiarities.
