A ZOOGEOGRAPHICAL CHARACTERISTIC OF MALACOFAUNA OF WATER BASIN OF THE CHULYM RIVER (SREDNEOBSKAYA ZOOGEOGRAPHICAL PROVINCE)
The article considers the species diversity of freshwater molluscs, and the composition of zoogeographical groups of mollusks in the river basin of Chulym. In the long process of historical development and the formation of the ancient river Pra-Ob and the Pra-Yenisey, Pra-Chulym was the southern corridor for the exchange of faunas of shellfish between Western and Eastern Siberia. Under the influence of these processes in the river basin Chulym formed a kind of modern complex freshwater mollusk, which has a great similarity with composition freshwater molluscs of the middle basin of the river Ob and of the basin of the river Sayan (the upper basin of the river Yenisei). The species composition of shellfish in the river basin Chulym, was been formed under the predominant influence of European and Siberian malakogenetics centers.
Keywords: malakofauna mollusks, freshwater mollusks, zoogeography, species composition, province, zoning
