Fit of the neutral community model (NCM) of community assembly and niche breadth for archaeal and bacterial communities. a, b: Fit of the neutral community model (NCM) of community assembly. The OTUs that occurred more frequently than predicted by the model are shown in green, while those occurred less frequently than predicted are shown in orange. Blue dashed lines represent 95% confidence intervals around the model prediction and the OTUs fall within the confidence intervals were considered as neutrally distributed. m indicates the estimated migration rate and R² indicates the fit to the neutral model. Neutral processes are the part within 95% confidence interval (red) while non-neutral are the parts including above and below prediction (dark green). c: Box plots illustrating standardized Levins’ niche breadth of bacteria and archaea at the community level (Bcom) in overall and four different types of vegetation zones. ***, P < 0.001 (Tukey’s HSD test). “Overall” is the combined data of four different types of vegetation zones, which represents the overall microorganisms in mangrove ecosystem
