ABSTRACT

The polymorphism of periostracum coloration and pattern was described first for Dreissena bugensis Andrusov. Morphological variability of its groups inhabiting areas of 5 dams of hydroelectric stations located on reservoirs of the Dnieper cascade was analyzed on 9 parameters of shell coloration and pattern. Samples collected both above and below the dams differed by their index of morphological variability.
