Flowchart of the study. a Two hundred seventy-nine water and sediment samples at 62 hydrologic stations in the Yangtze River covering the actual sinuous channel reach of length 6030 km (equivalent to 1.83 times the 3290 km straight line from start to end sampling sites). b Metabarcoding analysis provides insights into biogeographic pattern of diatoms along the mainstream of the Yangtze River, represented by the spatial distribution of Shannon diversity. c Interpretations on the biogeographic patterns of diatom communities, with main influencing factors such as photosynthetically active radiation (PAR), channel slope, and nutrients characterized by ratio of total nitrogen to total phosphate (TN:TP)
