Ecological processes shaping the microeukaryotic plankton community assembly at station G in Xinglinwan Reservoir. a The predicted occurrence frequencies for low, medium, and high salinity representing microeukaryotic plankton communities from low, medium, and high salinity periods in Xinglinwan Reservoir. The solid blue line is the best fit to the neutral community model (NCM), and the dashed blue line indicates 95% confidence intervals around the NCM prediction. OTUs that occur more or less frequently than predicted by the NCM are shown in green and red, respectively. R2 represents the fit to this model. b Comparison of mean habitat niche breadth for all taxa among low, medium, and high salinity levels (different letters indicate significant difference at the P < 0.05 level using Tukey’s post hoc test). c C-score metric using null models. The values of observed C-score (C-scoreobs) > simulated C-score (C-scoresim) indicate non-random co-occurrence patterns. Standardized effect size <− 2 and > 2 represent aggregation and segregation, respectively
