Multivariate analyses of physico-chemical water properties and fish assemblage structure in the study area. (a) Principal component analysis of physico-chemical properties measured at 71 sampling events through a complete annual hydrological cycle. (b) Nonmetric multidimensional scaling ordination based on fish assemblage structure at the same 71 sampling events. Red arrows represent environmental vectors significant at α = 0.05, with R² values. DO dissolved oxygen, EC conductivity, TB turbidity, TC temperature.
