황해생태계의 현재와 미래: 강제력들과 반응양상들

Abstract

Present study of the Yellow Sea examined a marine food web trophic continuum for quantifying the end-to-end food web structure, distributional characteristics and interactions of key/target species, and energy flow between trophic components in the Yellow Sea bottom cold waters. It examined the spatial and inter-annual distributions of cold waters, correlations between cold waters and marine climatic index, and factors affecting the physicochemical properties of cold waters. Studies of the organization of microbial loop and classical food-web structures correspond to the perspective of the planktonic ecosystem in cold waters. Essential studies include investigating the basic structure of trophic components and understanding how they affect the environmental characteristics of cold waters. Major research items are the spatial and inter-annual distribution of physicochemical factors (nutrients) and planktonic components (three size groups: phytoplankton, ciliates, and mesozooplankton), distribution and biomarker analysis of krill, and clarification of the ecosystem characteristics of cold waters (using stable isotopes) associated with cold waters. And research methods of floating micro-debris are briefly mentioned here with preliminary results in the coastal waters.s in the Yellow Sea bottom cold waters.
