Abstract

As researchers can modify environmental factors to fit the purpose of an experiment in monitoring marine ecosystem using enclosed experimental ecosystems, which is a strong advantage of them, mid-sized enclosed experimental ecosystems (mesocosm) are widely used in the world in basic ecology such as trophodynamic study and applied ecology such as the toxicity test of various chemicals and monitoring of ecosystem changes against marine pollution. Application of the mesocosm in the field has a merit to get more reliable result than that from the experiment in the laboratory. However, the result from the mesocosm study in marine ecosystem is very limited in Korea. Mesocosms which had been used in the marine ecological studies in both foreign countries and Korea were summarized, and application of them to the future study in various research field was suggested in this review paper.

폐쇄생태계는 연구자가 다양한 환경 요인을 조사 목적에 맞게 조절하여 생태계의 변화를 모니터링 할 수 있는 장점이 있어 영양역학적 연구와 같은 기초학문 연구뿐만 아니라 독성실험 및 환경오염에 대한 생태계의 변화 실험 등 응용분야에서도 활용도가 높다. 특히 현장에 해양 폐쇄생태계를 설치하기 때문에 실험실에서의 실험보다 자연에 가까운 조건에서 실험을 할 수 있어, 신뢰성 있는 실험 결과를 얻을 수 있다는 장점이 있다. 그러나 국내에서 폐쇄생태계를 활용하여 해양생태계를 연구한 결과는 극히 적다. 이 논문에서는 기존에 국내외에서 제작되어 실험에 사용되었던 폐쇄생태계와 이를 활용한 연구과제를 소개하고, 향후 폐쇄생태계를 활용하여 연구할 수 있는 연구과제를 제안하였다.
