Shannon diversity, a measure of how many species there are as well as how evenly the counts of individuals are distributed across species is plotted for every sample. There is wide variation among the HNP samples, with the oral (blue) and gastrointestinal (green) samples typically having more diversity than the skin (pink) or airway (coral) samples. Surfaces on the International Space Station have relatively high Shannon diversity, on par with that of the most diverse HMP samples, and the average home sample.
