Abstract

This review has dealt with definition, size, history, and status of mesocosm, and also discussed several problems and trouble shootings related to the building of mesocosm, and finally will suggest the future directions of this scientific tool. Due to the restriction of the space, the discussion mainly focused on "the mesocosm building for the soft-bottom ecosystem". The mesocosm is defined as "medium-sized, self-sustaining, and man-controllable ecosystem". This type of studies has already initiated since 1960, but nowadays it expands to the diverse fields of science and technologies, such as toxicology, limnology, environmental sciences and engineering, and even geochemistry. As a scientific tool, the mesocosm requires following aspects; replicability, repeatability, and ecological realism or accuracy. Several technical problems have to be solved for the perfect building of mesocosm. They are known as scaling, composition of seawater/sediment, light intensity, turbulence, hydraulic residence time, and top predator. These trouble shootings are provided at the discussion in detail. In the context, I expect two promising directions in the future; 1. Objectivity based on the diverse statistical methodologies, 2. "Living ecosystem modelling" coordinated with the mathematical modelling. With these, the mesocosm will be more powerful tool for the scientists and engineers to investigate the chemical and the ecological responses to the toxic materials and global climate changes.

본 연구는 mesocosm의 정의, 규모, 연구사례, 국내 외 연구동향, mesocosm 조성 시 일반적인 문제점, 해결방안을 거론하고, 끝으로 향후 발전방향을 제시하였다. 지면의 제약 때문에 주로 연성저질생태계(soft-bottom ecosystem)를 위한 mesocosm의 조성에 관련된 내용에 중점을 두었다. Mesocosm이란 규모적인 측면에서 "중형(1~1000 $m^3$)규모이며, 외부에서 먹이 공급 없이 스스로 유지가 가능하며, 환경의 일부 조건을 인위적으로 조절 가능한 인공생태계"를 말한다. 이러한 연구는 1960년대 중반부터 해양/담수생태계, 특히 해양식물플랑크톤이 주 연구 대상이었으나, 점차 확대되어, 최근에는 독성학, 육수학, 환경학, 환경공학, 지구화학 등 다양한 분야에서 흔히 사용하는 도구가 되었다. 과학적인 도구의 하나로서 mesocosm은 기본적으로, 1. 재현성(replicability), 2. 반복성(repeatability), 그리고 3.생태학적 현실성(ecological realism or accuracy)이 구비되어야 한다. 여기에 구체적으로 필요한 규모(scaling), 퇴적물과 해수의 조성, 광량, 난류(亂流), 물 교환율, 포식자 등 기술적인 문제에 대한 해결책을 상세히 언급하였다. Mesocosm이라는 과학적인 도구의 미래 발전 방향은 1. 다양한 통계기법을 통한 객관성의 확보, 2. 수치모델분야와 상호 보완하여 "생태계의 살아 움직이는 모델"로서 보다 더 광범위한 적용이 될 것이다. 앞으로 독성물질에 대한 생태계의 반응 및 독성물질의 거동과 지구온난화에 대한 생태계 및 지구환경의 반응 등을 예측하는데 mesocosm은 매우 유용한 도구가 될 것으로 확신한다.
