This study analyzed the composition and distribution of the macrozoobenthos of the soft soils of the Far Eastern Marine Biosphere Reserve. Found 176 species, classified in six groups: Polychaeta, Bivalvia, Gastropoda, Cumacea, Isopoda, Echinodermata. The greatest variety of typical for polychaete worms (67 species) and bivalves (48 species). Found that the coefficient of variation in the ratio of the number of major taxonomic groups for soft ground of sublittoral reserve (1.02) is slightly higher than for water areas with domination of the soft soils in northern latitudes (area of Spitsbergen and the North Sea), and is closer to that of the bays and coves of the South China Sea and the North-East coast of Australia.
Несколько предложения, которые я не смог перевести:
Patchy distribution of calcaneal mats polychaete S. armiger, Onuphis shirikishinaiensis and ophiuroids O. sarsi (common in the square from several m2 up to several tens m2) leads to aggregation of crustaceans and polychaetes, inhabiting these mats
On some latitudinal trends-topping position above polychaetes molluscs and crustaceans in the soft soils – mentioned earlier
Granulometric variety of soil samples were taken from small boulders and gravel on silted sand-probably can find enough
room for the existence of more species, which leads to a reduction in individuals inhabiting this biotope.
