Changes of Periphyton Abundance and Biomass Driven by Factors Specific to Flooding Inflow in a River Inlet Area in Erhai Lake, China

Periphyton is an ecological essential in freshwater lakes and rivers. Its abundance biomass are very dynamic various habitats subject to factors, for example, nutrient light. Following flooding events, the transitional area adjacent a river inlet shallow lake generates diverse periphyton with gradients current velocity, suspended matters, nutrients, light, which would strongly shape growth community of periphyton. In this study, three sampling sites were established around Erhai Lake, China, field survey was conducted from April August (flooding seasons) 2019 investigate explore influential factors. The results showed that study areas have different velocity depending on distance inlet, thereby regulating concentrations nutrients affected community; be specific, inhibited by concentration matters high silicate mainly reduced diversity Our imply driving factors could help understand its assembly mechanism species composition can provide some reference trophic state lake.
