Popis:	The main differences in the structure and species diversity of topical groups of mollusks between lakes on Solovetsky Island and continental lakes have been revealed. Insular groups are characterized by higher indices of species richness (the average number of species per sample) and density, with the level of dominance being decreased. In general, specific features of the insular territory impose limitations not only on the total species richness but also on the number of structural variants of topical mollusk groups, with the range of parameters of their species diversity being reduced against the background of sharp increase in the density of mollusk colonies. Insular topical groups of mollusks are characterized a certain set of species dominating in abundance.
