Tropical seagrass meadows and coral reefs often function as interconnected marine habitats, but they are often studied and managed as homogenous units. As macrohabitats, seagrass meadows provide important benefits to adjacent reef ecosystems by acting as natural filters of sediments and nutrients, and by providing critical feeding, nursery, and refuge habitats for reef fishes and other fauna. Whilst the macrohabitat functions of seagrass meadows have been often acknowledged, their microhabitats functions have largely been neglected. The purpose of the study is to explore how seagrass meadows provide multiple benefits to adjacent coral reefs through various microhabitat functions. The paper reveals some of the diversity of microhabitats that seagrass meadows contain, such as macroalgal mats, rubble cavities, sand patches with sparse seagrass, anemone gardens, hard substratum, and sponges mixed with seagrass. We highlight the ways in which reef creatures have diversified and specialized in using these different microhabitats, and postulate that seagrass microhabitat diversity enhances the habitat function and faunal diversity of seagrass meadows.

海草草甸通过各种微生境功能为邻近的珊瑚礁提供多种好处

热带海草草甸和珊瑚礁通常起着相互联系的海洋栖息地的作用,但它们通常作为同质单元进行研究和管理。作为大型栖息地,海草草甸通过充当沉积物和养分的天然过滤器,并为礁鱼和其他动物提供重要的觅食,苗圃和避难所栖息地,为邻近的礁石生态系统提供了重要的好处。尽管人们经常承认海草草甸的宏观栖息地功能,但很大程度上忽略了它们的微观栖息地功能。该研究的目的是探索海草草甸如何通过各种微生境功能为邻近的珊瑚礁提供多种益处。该文件揭示了海草草甸所包含的一些微生境,例如大型藻垫,瓦砾洞,稀疏的海草沙斑,海葵花园,坚硬的基质和混有海草的海绵。我们重点介绍了礁生物如何利用这些不同的微生境进行多样化和专门化,并假设海草微生境的多样性增强了海草草甸的栖息地功能和动物区系多样性。
