摘要：

A study of vertical distribution of dinoflagellate cysts in recent sediments was conducted for the first time in the Far Eastern seas of Russia. Dinoflagellate cysts were studied in sediment cores retrieved from five stations in Amur Bay (Peter the Great Bay, Sea of Japan) in 2010 and 2013. The Scrippsiella trochoidea complex was the dominant type of cyst, the average proportion of which (in the entire sediment cores) reached 39% of the total cyst abundance. The maximum abundance of S. trochoidea complex reached 5513 cysts g(-1) dry sediment. Cysts of the S. trochoidea complex were found to remain viable in the sediments after exposure to sub-zero temperatures. The identification of S. trochoidea in the Far Eastern seas of Russia was first confirmed by using biomolecular genetic analyses. The study of vertical distribution showed that cysts of this species dominate the upper sediment layers (0-10 cm). A tendency for abundance to increase from the shore toward the middle part of the bay was observed in the spatial distribution of cysts.
