海洋保护区珊瑚潮间带生境是研究底栖生物群落物种多样性和生态功能的重要模式系统。片足类物种组成和功能性状的空间变异性进行了研究，在3年的时间在夏季在5个潮间带断面的卡奇赫湾（GoK）海洋保护区，印度。共鉴定出22，706个个体，隶属于23科40属71种。其中，海鲶科、Dexaminidae、Eriopisidae、Lysianassidae和Maeridae是最具代表性的科，占总丰度的68.2%。沿水平和垂直轴沿着，端足类的群聚结构和功能特征具有明显的空间格局。结果表明，端足类组合功能的垂直梯度的影响很大，一般较高的功能多样性（FD）在较低的潮间带，资源利用策略的多样性增加，而上带显示很少FD可能是由于流行的环境过滤。由于较高的物种和功能多样性促进了更好的资源分配和生态系统的恢复力，这些结果对于面临全球气候变化和人为压力双重挑战的海洋保护区的管理非常重要。
Coralline intertidal habitats of marine protected areas (MPAs) are important model systems to investigate species diversity and ecological functioning of benthic communities. Spatial variability of amphipod species composition and functional traits were studied over a 3 year period during the summer season at five intertidal transects of the Gulf of Kachchh (GoK) MPAs, India. A total of 22,706 individuals, comprising 71 species belonging to 40 genera and 23 families, were identified. Aoridae, Dexaminidae, Eriopisidae, Lysianassidae, and Maeridae were the best represented families (68.2% of total abundance). Distinct spatial patterns in the amphipod assemblage structure and functional traits were observed along the horizontal and vertical axes. The results demonstrated that the amphipod assemblage functioning was greatly influenced by the vertical gradient, with generally higher functional diversity (FD) in the lower intertidal zones suggesting increased diversity in resource use strategies, whereas the upper zones showed very little FD possibly due to the prevalence of environmental filtering. As higher species and functional diversities promote better resource partitioning and resilience of the ecosystem, these results are important for the management of MPAs facing the dual challenges of global climate change and anthropogenic pressures.
