Seasonal and long-term dynamics of sand-dwelling dinoflagellates (Dinoflagellata) in Peter the Great Bay, Sea of Japan

Seasonal and long-term dynamics of sand-dwelling dinoflagellates (Dinoflagellata) in Peter the... The seasonal and long-term dynamics of the species composition and abundance of dinoflagellates that live in subtidal sands in Russian waters of the Sea of Japan was studied for the first time. The overall species composition of sand-dwelling dinoflagellates in Peter the Great Bay was represented by 67 taxa that belong to 25 genera. Among them, 17 species were recorded for the first time from the seas of Russia, and 8 species were found from the Pacific coast of Russia for the first time. The greatest number of species belonged to the genera Amphidinium, Amphidiniopsis, and Thecadinium. A list of the species composition, including the distribution of taxa throughout the localities and seasons, is presented. Most species of the microalgae are illustrated by light and scanning electron micrographs. The species richness varied from 18 to 44 during the year. In the winter, at a water temperature less than 0°C, the species richness of sand-dwelling dinoflagellates (24–26 taxa) roughly coincided with that found in summer (20–44 taxa). The average density of dinoflagellates ranged from 16 to 1121 cells/cm3 across localities and throughout the year. During the annual cycle, the highest cell density (595 and 2576 cells/cm3) were recorded in the winter–spring period and a slight increase in abundance was observed in fall. This was due to the high cell densities of the dominant species Amphidiniopsis uroensis Toriumi, Yoshimatsu et Dodge, and Thecadinium kofoidii (E.C. Herdman) Larsen. Sand-dwelling dinoflagellates contributed 58 to 80% to the total annual density of the subtidal microphytobenthos in different localities of Peter the Great Bay.
