Qualitative trait comparison for abundant taxa (> 0.1% of reads in at least one sample; see also Supplementary Information I). a Proportion of taxa with a specific, qualitative trait in skin microbial communities (x-axis) versus the world as a whole (y-axis). Filled symbols represent traits that are significantly different in skin environments; open circles represent traits that are not significantly different; marker size reflects significance. b Plots of trait proportions among skin bacteria (pink) and world bacteria (green). Open red circles denote traits that are overrepresented on skin; filled green circles denote traits that are overrepresented in the world (underrepresented on skin)
