ROLE OF <i>VIVIPARUS VIVIPARUS</i> (L.) (GASTROPODA, VIVIPARIDAE) IN FORMATION OF MACROINVERTEBRATE COMMUNITIES IN NOVOSIBIRSK RESERVOIR
The results of an investigation into the size structure and spatial distribution of Viviparus viviparus (L.) in Novosibirsk reservoir are presented. The abiotic factors contributing to species dispersal are analyzed. The change in taxonomic structure of macroinvertebrate communities at the sites of V. viviparus dispersal is noted.
