It is the goal of this study, to establish triple (13C, 15N, 34S) stable isotope analysis as a tool for the analysis of aquatic food webs. The triple isotope analysis has a particular potential for wood webs which are characterized by bentho-pelagic coupling, as it is typical for coastal and shallow seas. We will use a seagrass meadow in the vicinity of Kiel and the overlying water column as a model system. This model system is chosen because seagrass meadows- are among the most productive marine ecosystems- are important nursery grounds for fish and other fauna- are globally endangered- are complex systems in terms of the diversity of number of basal carbon sources and of bentho-pelagic coupling.During 2 growth seasons, all important components of the food web will be sampled for subsequent stable isotope analysis and analysis of fatty acids as indicators of trophic relationships.

本研究的目的是建立三重（13 C，15 N，34 S）稳定同位素分析作为分析水生食物网的工具。三重同位素分析对具有海底-水层耦合特征的木网具有特别的潜力，因为它是沿海和浅海的典型。我们将使用基尔附近的海草草甸和上覆水柱作为模型系统。选择该模型系统是因为海草草甸-是最具生产力的海洋生态系统之一-是鱼类和其他动物的重要苗圃地-是全球濒危的-就基底碳源数量和底栖-浮游耦合的多样性而言是复杂的系统。在2个生长季节期间，将对食物网的所有重要组成部分进行取样，以便随后进行稳定同位素分析和脂肪酸分析，作为营养关系的指标。
