Figure 3

Richness and diversity of the Parisian street gutters and the non-potable sources. (a) OTU richness values of the raw water (RW), flowing water (FW) and gutter mats (GM) compartments based on the Chao1 richness estimator. Small letters above the boxplots indicate significantly different distributions (Kruskal–Wallis, P<0.05); (b) global non-metric multidimensional scaling (GNMDS) ordination of the microbial community composition based on Bray-Curtis distances; (c) Venn diagram indicating the specific and/or shared eukaryotic OTUs between the non-potable sources (NPS=FW and RW) and the gutter mats (GM) compartments; (d) taxonomic composition of the compartment-specific OTUs identified by LEfSe analysis. Refer to the legend of Figure 2 for the code used for the different taxonomic assignations.
