The latitudinal-zonal distribution of fresh¬water mollusks and ecological and biogeographical regionalization of Northern Siberia
The distinctive features of the latitudinal-zonal distribution of fresh-water mollusks in the water basins of Western, Middle and North-Eastern Siberia are discussed. The species composition of mollusks occurring in the various types of basins of every region is reported, moreover, the Pulmanata-to-Branchiata ratio is considered. As based on the biotopic features and malacofauna composition, a series of present-day ecological - zoogeographical complexes is distinguished and the species composition of malacofauna is reported. By pooling data on the current composition and distribution of the ecological - zoogeographical complexes of mollusks, the ecological - zoogeographical regionalization of North-Siberia basins has been updated.
