Figure 2

Correlation triplots based on redundancy analysis (RDA) displayed the variations of relative abundances of Accumulibacter specific-clade in
a) the bacterial communities and b) the Accumulibacter lineage, basing on the qPCR assays targeting ppk1 genes and bacterial 16S rRNA genes, with respect to the variable operational conditions among wastewater treatment plants. Each Accumulibacter clade is represented in green line, each activated sludge sample is indicated by a color point. Operational variables are indicated by orange lines.
