Diversity and ordination of ISS and SAF samples based on species-level microbial populations. Abundance of each microbial species, as determined by unique mapping of sequence reads obtained from each ISS and SAF sample, was used to perform ecological diversity analysis and sample-level ordination. a Diversity estimates for each sample type, as quantified by calculation of Chao1 richness and alpha diversity using the Shannon entropy and Gini-Simpson indices, based on absolute read counts. b Principal coordinate analysis using the Bray-Curtis distance of the ISS and SAF-derived samples based on absolute read counts. PMA-treated samples are shown in triangles, and untreated samples are shown in dots. Dust samples are shown in orange color, and filter samples are shown in green color
