From: Deep amoA amplicon sequencing reveals community partitioning within ammonia-oxidizing bacteria in the environmentally dynamic estuary of the River Elbe

Figure 4

Canonical correlation analysis of the of ß-AOB community composition on OTU level and environmental parameters. If the Bonferroni corrected padj was < 0.05, a given parameter was included. The two clusters of communities found at the different sites (Fig. 3) are mainly explained by the relative abundance of OTUs related to the Nitrosospira-lineage and the Nitrosomonas oligotropha-lineage. Cadmium, zinc and water depth explain 42.7% (adjusted) of the compositional variation among the analyzed sites which is interpreted as a co-correlation caused by the coupled transport of ß-AOB and heavy metals along the river transect, investigated. Analyses are based on amoA amplicons.
