Abstract

The community structure of meiobenthos was investigated from seasonal surveys at four stations of Keunso Bay in Taean. Samples of meiobenthos were collected in August, October, 2013 and January, April, 2014. Triplicate faunal samples were collected by using an acryl corer with a 3.6 cm diameter at each station. The mean grain size of the study area ranged from 3.65 ø to 6.35 ø. Total 13 meiofaunal groups were found in the study area. The total density of meiobenthos at each station was be $1,521-7,849ind./10cm^2$. Nematodes were the most dominant faunal group at all stations. The subdominant group were Sarcomastigophorans and benthic harpacticoid copepods. The highest meiofaunal density was shown in spring, whereas the lowest density was recorded in summer. A total of 13 meiobenthic taxa were found, the richest taxa in October at station 2 ($13ind./10cm^2$), and the lowest in April at station 4 ($5ind./10cm^2$). There were seasonal fluctuations in the number of meiobenthic taxa decreasing from summer to spring. The density of meiobenthos gradually decreased as the depth of sediment increased. Seasonal changes in the vertical distribution of meiobenthos in the study area occurred mainly near the sediment surface.

서해 중부에 위치한 태안 근소만의 4개 정점에서 중형저서동물군집의 계절조사를 실시하였다. 중형저서동물 시료는 2013년 8월과 10월, 2014년 1월과 4월에 각 계절을 고려하여 채집하였으며, 직경 3.6 cm의 아크릴코어러를 이용하여 각 정점에서 반복수 3개의 시료를 채집하였다. 연구지역에서의 평균입도는 3.65 ø에서 6.35 ø 사이의 값을 보여주었다. 중형저서동물 군집은 총 13개의 분류군이 출현하였고, 각 정점에서 전체 서식밀도는 $1,521-7,849ind./10cm^2$의 값을 나타내었다. 출현 분류군 중 가장 우점하는 그룹은 선충류로 나타났으며 그 다음으로는 저서유공충류, 저서성 요각류의 순으로 나타났다. 서식밀도는 봄에 가장 높은 값을 보였고 여름에 가장 낮은 값을 보였다. 출현 분류군 수는 총 13개 중형저서동물 분류군이 나타났으며, 2013년 10월 정점 2에서 가장 높은 13개, 2014년 4월 정점 4에서 가장 낮은 5개로 나타났다. 출현 분류군 수의 계절적 변동은 여름에서 봄으로 시간이 지날수록 감소하는 것으로 나타났다. 퇴적물 표층에서 깊이가 깊어질수록 중형저서동물의 서식밀도는 점차 감소하는 양상을 보였고, 수직분포 변화를 통해 본 계절적 변동은 표층 0-1 cm에서 가장 크게 서식밀도의 차이를 보였다.
