Fig. 8From: The bacterial community composition and its environmental drivers in the rivers around eutrophic Chaohu Lake, ChinaRedundancy analysis ordination plots show the relationship between two key environmental variables (CODMn and NH4+) and bacterial community structure, as reviewed by assessing 16 S rRNA gene OTUs. The nominal variable ‘‘sampling site’’ is represented as centroids. Environmental variables that are significant are shown by * (P < 0.05), and *** if very significant (P < 0.01)Back to article page
