Effects of geography and related factors in driving public transit air microbiome. Colours represent each city: Denver (orange), Hong Kong (red), London (purple), New York (blue), Oslo (yellow), Stockholm (green). a Relative abundance of bacteria, fungi, virus, and archaea across cities. b Density plot of core species-level taxa (present in ≥ 75% of all samples). c and d Significant differences between c Shannon diversity index (Wald chi-square test p = 2.3 × 10−26) and d normalized richness (Wald chi-square test p = 5.5 × 10−25) of public transit air microbiomes were detected. Asterisks above horizontal bars indicate mixed model pairwise comparison significance following Tukey method p-value adjustment: *p < 0.05, **p < 0.01, ***p < 0.001. e Principal coordinates analysis plot of community composition based on Bray-Curtis dissimilarity of public transit air microbiomes grouped by city. The normal confidence ellipses indicate the confidence level at 95%
