Rotifers, small but essential invertebrates in aquatic ecosystems, are sensitive to environmental changes and are proposed as indicators of trophic state. However, the effects of hydrological heterogeneity on the rotifer community and the ability of rotifer indices to reflect trophic state when comparing different water bodies are still unclear. Here, we investigated rotifer community structure in different seasons in the three types of water bodies: Han river downstream (HD), Reservoir (RE) and Tidal creek (TC) in Shantou City, Guangdong, China. Our findings revealed that rotifer community structure differed significantly among the three water bodies, resulting from a dominance of Keratella cochlearis, Anuraeopsis fissa and Polyarthra vulgaris, who largely accounted for the differences of water bodies. Chlorophyll-a and Transparency were the main environmental drivers in RE rotifer communities, while Total Nitrogen, Total Phosphorus and salinity were the main factors in HD and TC communities. Rotifer abundance and the rotifer trophic state index decreased in the order: RE > HD > TC. However, both the Sladecek’s B/T quotient and the Keratella-index decreased in the order: HD > RE> TC, which was in accord with the Carlson’s trophic index. We conclude that it is efficient to use rotifer composition in water quality assessment when comparing different water bodies. Alpha diversity of rotifers was the highest in HD, which is consistent with the intermediate disturbance hypothesis. Hydrological heterogeneity were the macro-factors that regulates rotifer community structures in Shantou area.
