| The Community structure of meiobenthos was studied seasonally at 5 stations of Bangameori tidal flat and 3 stations of subtidal area in Daebudo near the Shiwha dike in the west coast of Korea, from May 2000 to February 2001. Mean grain size of intertidal stations ranged from $3.16;varphi;to;3.73varphi$ (sand), subtidal stations were $5.81~6.67;varphi$ (mud). Nematodes were the most dominant group among the representative 19 meiofaunal groups at all stations in both tidal flat and sub-tidal area. The subdominant groups were benthic harpacticoid copepods and Sarcomastigophorans. The density of meiobenthos ranged from 145 inds. $10cm^{-2}$ to 2,057 inds. $10cm^{-2}$ (0~1 cm) in the sediment of intertidal stations, and from 391 to 3,787 inds. $10cm^{-2}$ (0~5 cm) in the subtidal stations. The lowest meiofaunal density was recorded in winter, whereas the highest density was shown in spring. Comparing with another previous work at the same area, data from this study does not statistically shown differences with results before discharge of shiwha lake water. |
