Microbial diversity of forearm skin microbial ecosystem. Alpha diversity indices of nseqs (total number of sequences), invsimpson (phylogenic diversity), chao (species richness), and shannoneven (species evenness) in the investigated individuals from the Dairy farm in Clarksville (A), the integrated farm in Upper Marlboro (B) and Washington DC (C), and University of Maryland—College Park campus (D). Letters a and b indicate significant differences among groups based on ANOVA. The widths of the boxes represent the variances in the observations.
