초록

본 연구는 제주 연안에 서식하는 중형저서동물 군집의 특성과 계적적 변동을 알아보고자 수행되었다. 제주도 조간대 지역에서 20개의 조사지점을 선정하였으며, 2017년 4월부터 2019년 2월까지 총 8회의 조사를 수행하였다. 조사결과, 조사지점 당 중형저서동물의 밀도는 733~2,505 inds. 10 cm-2였으며, 2017년 4월에 밀도가 가장 높았고 2019년 2월에 가장 낮았다. 모든 조사지점에서 Nematode가 우점하고 있는 것으로 나타났으며, copepod와 nauplius가 그 다음 우점 분류군으로 조사되었다. 생태계 건강성을 나타내는 Nematods/Copepods ratio (N/C ratio)는 2017년 4월에 가장 낮은 값인 0.02, 2019년 2월에 가장 높은 값인 87.40으로 산출되었으며, 이는 조사지점의 건강성이 악화되었음을 의미한다. Multi-Dimensional Scaling (MDS) 분석결과는 제주 연안의 중형저서동물 군집구조는 지역적 차이보다는 계절적 변동에 의해 더 크게 영향을 받고 있음을 나타냈다. 제주도의 중형저서동물 군집의 계절적 변동 특성을 보다 명확히 이해하기 위해서, 추가적인 군집조사와 환경 인자와의 상관관계 분석이 후속 연구로 필요할 것으로 판단된다.

To observe the seasonal fluctuation of the meiobenthic fauna community around the coastal area of Jeju island, 20 stations were selected and seasonal surveys were conducted. Three-replicate meiobenthic samples were collected from each station in April, July, and November 2017; February, May, August, and November 2018; and February in 2019, in a total of eight months from 2017 to 2019. The total density of meiobenthos at each station ranged from 733 to 2,505 ind. 10 cm-2. The month in which the highest habitat density appeared in most stations was April 2017 and the month in which the lowest habitat density was seen was February 2019. Nematodes were the most dominant faunal group among the representative 13 meiofaunal groups at all stations. The subdominant groups were benthic harpacticoid copepods and nauplius. The nematode/copepod (N/C) ratio, reflecting the health indices within the ecosystem, varied from 0.02 to 87.40 over the entire season and the average station values ranged from 2.00 to 16.80. The lowest N/C ratio value was found in April 2017 (0.02) and the highest N/C ratio was found at Station 11 in February 2019, which was 87.40, indicating the highest level of pollution. Seasonal and regional meiobenthos community structure similarity was divided into three groups through group analysis and multi-dimensional scaling (MDS) analysis, which showed that the meiobenthos community structure was affected by seasonal variations, rather than by regional differences.
