Fatty acid biomarkers provide promising novel tracers for studying estuarine food chains. Stable isotopes, commonly employed in food chain studies, lack specificity to allow easy determination of feeding relationships. Different primary producers are characterised by unique fatty acid sequences. This study will thoroughly evaluate the applicability of fatty acid biomarkers in tracking both natural and human-impacted estuarine food chains. By developing a new approach of combining the advantages of fatty acid bioamrkers and stable isotopes in studying estuarine trophodynamics, this study will provide essential information for the management of estuarine biotic resources.

脂肪酸生物标志物为研究河口食物链提供了新的示踪剂。稳定同位素，通常用于食物链的研究，缺乏特异性，使容易确定的喂养关系。 不同的初级生产者的特征在于独特的脂肪酸序列。本研究将全面评估脂肪酸生物标志物在追踪自然和人类影响的河口食物链中的适用性。本研究将脂肪酸生物标志物与稳定同位素的优势结合起来，为河口营养动力学研究开辟了新的途径，为河口生物资源的管理提供了必要的信息。
