Relationships between community similarity and river channel slope for water-spring (a), water-autumn (b), sediment-spring (c), and sediment-autumn (d) samples. Values of Mantel Spearman correlations (r) and probabilities (P) are also provided. Gray lines denote ordinary least squares linear regression fits across all samples. Spatial distributions of ecological guilds for different channel slopes are shown in (e)
