Figure 4

Drivers of E. coli population structure. Venn diagrams of the results of variation partitioning analysis of response variables explained by environmental, urban infrastructure and spatial contributing factors: (a) abundance of E. coli; (b) phylogenetic composition. The contribution of each predictor set is represented by R2 adjusted values and p-values, when available; values < 0 are not shown. Significant parameters derived from each pRDA from each predictor matrix are listed in each diagram (p < 0.05); color-shaded areas represent the evaluated fraction for each main matrix. DIN, dissolved inorganic nitrogen; SRP, soluble reactive phosphorus; AEM, asymmetric eigenvector map; Res, residuals. Data analysis performed in R software73. Graphical edition in Inkscape V 0.92.4.
