A Redundancy analysis (RDA) indicating relationships between environmental factors and seasonal dynamics of bacterial community. Only significant environmental factors are plotted (p < 0.05). Temp: temperature; TP: total phosphorus; Sal: salinity; DSi: active silicon; PO43−–P: phosphate phosphorus. B Boxplots illustrating the average niche breadths of all OTUs at the community level (Bcom) in different seasons. Horizontal black lines show the median values. The values of Bcom have a significant difference among different seasons (Kruskal–Wallis test, p < 0.05). Letters refer to pairwise comparison results after the Kruskal–Wallis test and the absence of the same letter means a significant difference between the two niche breadths (p < 0.05)
