Studies on the Ecosystem in the Yeong-Il Gulf of Korea: I. Species Composition and Diversity of Phytoplankton Communities
Eun-Yung Jo, Jae-Hoon Cha, Mi-Kyung Kim, Ki-Tae Kim
ABSTRACT
In order to clarify the capacity of productivity, distribution and dynamics of phytoplanktons which play an important role as the primary producer, we tried to analyze their species composition and community and community along the coast of Yeoung-Il Gulf from May 1998 to May 1999. The taxa of phytoplanktons observed in this coast were classified as 4 divisions, 6 classes, 10 orders, 3 suborders, 26 families, 200 species (182 species, 1 subspecies, 12varieties, 5 forms). The 149 species of diatoms were recognized with 31 species of dinoflagellates, 4 species of silicoflagellates, 11 species of chorophytes, 1 species of euglenophytes and 4 species of cyanophytes. The number of species was the highest in August when 66 species were observed. The most frequent species were Licmophora abbreviata AGARDH(51%), Thalassionema nitzschioides HUSTEDT(39%) and Ceratium furca (EHRENBERG) CLAPAREDE et LACHMANN(29%). The cell density of phytoplanktons was the highest (1,218 x 10 super(3) cells·l super(-1)) on the downstream area of Hyeung-San River in May 1998 (4.6μg·l super(-1)), which the lowest value was in February 1999 (0.4μg·l super(-1)). The standing crops of phytoplanktons were remarkably high in spring, summer and autumn. This examination of phytoplankton study will be continued for the fundamental database of ecosystem study in the Yeong-Il Gulf.
