Periodic inundations drive community assembly of amphibious plants in floodplain lakes

Understanding the effects of disturbance regimes on community assembly is an essential issue in community ecology. Yet, little is known about how water regimes drive community assembly considering functional facets in aquatic communities. We detected functional trait patterns of amphibious plant communities and checked the effects of inundations on these patterns, using null model analyses based on observational data of 20 Yangtze River floodplain lakes. Amphibious plant communities in the study lakes were dominated by perennials and a large proportion (61.2%) of communities were species-poor (species richness
