Ecoelementary structure of population of the Black sea Mussels (Mytilus galloprovincialis Lam.) of the east part of the Black sea
On the basis of specially developed technique the morphotype of Mililus galloprovincialis sample from nine different habitats of east part of Black sea is described. By means the cluster analysis, three or four morphologically different groups within each sample were identified. Representation about them as about primary group formations with which natural selection operates is proved.
