To clarify the impacts of the floating-leaved macrophyte (Trapa japonica) against aquatic ecosystems, we compared spatial structures and epiphytic fauna between T. japonica and typical submerged macrophyte, Hydrilla verticillata. Spatial structures of T. japonica were less complex than those of H. verticillata. Despite environmental conditions of their habitats were not different between these macrophytes, species diversity of epiphytic animals was higher on T. japonica. The results suggest that T. japonica take a role as the key-stone species, maintaining diverse epiphytic fauna.

为阐明浮叶菱对水生生态系统的影响，比较了浮叶菱与水曲柳的空间结构和附生区系特征。典型沉水植物黑藻Hydrilaverticillata。T. japonica比H.轮生植物。尽管这些水生植物的生境环境条件没有差异，但附生动物的物种多样性在T。日本。结果表明，T. japonica作为关键种，维持了附生植物区系的多样性。
