Clustering and microbial community composition of different volunteers and epidermal layers. Samples were clustered using UPGMA with weighted UniFrac as a distance measure. The figure was generated with iTOL . Sample names with the same color come from the same volunteer (M = male 1 to 6, F = female 1 to 6), followed by the stripping depth (STR0, STR5, STR10). Colored bars represent the relative abundance (the number of reads assigned to a genus divided by the total number of reads assigned up to the phylum level) of bacterial genera as determined by barcoded pyrosequencing.
