RT Journal Article ID 4d8e2fe971a17461 T1 Morphological Variability of Dreissena bugensis Andrusov Under Conditions of the Regulated Dnieper Outflow JF Hydrobiological Journal JO HYD YR 2000 FD 2000-10-01 VO 36 IS 5 OP 8 AB 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.
