Abstract
This study was conducted to examine the community structure of macrobenthos on Angel tidal flat in Jinhae, south coast of Korea. Monthly samples were conducted at eight sites from March 1998 to February 1999. A total of 110 species were sampled with a mean density of 322ind. $m^{-2}$ and biomass of 98.4 wwt g $m^{-2}$. Of these species, there were 44 species of polychaetes $(40.0\%)$, 41 species of crustaceans $(37.3\%)$ and 16 species of molluscs $(14.5\%)$. The major density dominant species were a gastropod Batilaria cumingi (52ind. $m^{-2}$) and five polychaetes Ceratonereis erythraeensis (38ind. $m^{-2}$), Cirriformia tentaculata (32ind. $m^{-2}$), Capitella capitata (23ind. $m^{-2}$), Sigambra tentaculata (23ind. $m^{-2}$), Glycera chirori (17ind. $m^{-2}$). Cluster and MDS analysis showed that the study sites could be divided into two tidal elevation groups. According to the spatial distribution of dominant species and SIMPER analysis, the two groups were characterized by Sigambra tentaculata - Chaetozone setosa in upper species group and Ceratonereis erythraeensis-Cirriformia tentaculata-Capitella capitata in lower species group.
