New data on David's myotis, Myotis davidii (Peters, 1869) (Mammalia, Chiroptera, Vespertilionidae), in Siberia and the Urals

David's myotis, Myotis davidii, is a vespertilionid bat inhabiting the wide spaces of the Palearctic region. Although previously registered in the north of Mongolia (50° N.L.) and the southern Urals (52° N.L.), data on the ecology of the species on the northern periphery of the range was missing. The northern border area of M. davidii in Siberia shifts by 350 km and the area increases by about 150,000 km2, in the Ural area by 150 km. Pups in the north of the range appear from the second half of June to July inclusive. Our data reveal that individuals from the Urals and the North Caucasus are genetically similar
