Figure 2.

Boxplots of (A) OTU richness, as measured by CatchAll, (B) Shannon Diversity, and (C) Faith's Phylogenetic Diversity of microbial OTUs. Boxplots represent variation over repeated collections of sediment and water samples respectively. Sites are plotted in order of increasing watershed impervious cover. Plots comparing diversity to watershed percent impervious cover are presented in Supplementary Figure 1.
