ABSTRACT

The number of species of Polychaeta and their diversity were studied in various biotopes of the northwestern part of the Black Sea. The highest value of the Simpson index of diversity was registered in the biotope of shell rock, whereas its lowest value was observed in the biotope of silt. In 1998 as compared to 1977 the indices of diversity remained almost unchanged, whereas the ecological diversity of Polychaeta (relationship between their vital forms) essentially changed.
