SEASONAL-CHANGES IN POLYCHAETA TAXOCENES OF THE SUBLITORAL IN THE FAR-EASTERN MARINE RESERVE

At two stations located in the Gulf of Peter the Great of the Sea of J apan, on sand at depths of 10 and 47 m, the authors studied seasonal c hanges in Polychaeta taxocenes. The most significant variations in the taxocene's species structure were noted at the depth of 10 m. With th e help of multiple discriminant analysis, within the bounds of each ta xocene they distinguished two seasonal aspects, with summer changes at the depth of 10 m leading those at the depth of 47 m in time. The pro blem of relating temporal fluctuations with the concept of a community as such is discussed.
