摘要
食物资源对海洋动物的生存和繁衍至关重要。海洋动物的营养生态位描述了其在海洋生态系统中的生态地位及功能,对分析种间关系和资源分配模式、了解群落结构与功能具有重要的指示作用。本文在整理近30年来国内外相关研究的基础上,系统归纳了当前海洋动物营养生态位研究的主要方法(胃含物分析、整体组织稳定同位素分析、脂肪酸组成分析和特定化合物稳定同位素分析)及其应用领域,着重归纳总结了量化营养生态位宽度和重叠的生态模型,并分析了各营养生态位评估方法的优势和局限性。同时在此基础上,对今后研究方向提出了展望,以期为我国海洋动物摄食生态学相关研究工作提供参考。
Food resources are crucial for the survival and reproduction of marine animals.The trophic niche of marine organisms refers to the ecological roles and functions in marine ecosystem.It plays an important role in studying interspecific relationship,resource partitioning,community structure and function.In this study,by collecting the relevant research on trophic niche of marine animals,we review current research methods(stomach content analysis,bulk tissue stable isotope analysis,fatty acid profiles and compound-specific isotopic analysis)and their applications by focusing on their corresponding ecological models on quantitively evaluating the breadth and overlap of the trophic niche.Moreover,potential development and directions for further studies are presented,with the aim of providing supports for future research on feeding ecology of marine animals.
