Fig. 1.
Differences in alpha and beta diversity between airborne bacteria (AB), airborne BEVs (AE), soil bacteria (SB), and soil BEVs (SE).
(A) Alpha diversity: observed OTUs, Chao1, Shannon index, and Simpson index. (B) Beta diversity: PCoA of the bacteria and BEVs. (*: p < 0.05.).
Fig. 2.
Dominant microbiome in air and soil.
(A) Averaged microbiota at the phylum level. (B) Dominant genera of bacteria and BEVs based on total read counts in air samples. (C) Dominant genera of bacteria and BEVs based on total read counts in soil samples.
Fig. 3.
Difference in dominant (A) functional pathway and (B) orthologous groups between airborne bacteria (AB), airborne BEVs (AE), soil bacteria (SB), and soil BEVs (SE).

Heatmap of correlation between dominant genera, dominant functional pathways, and orthologous groups in (A) airborne bacteria, (B) airborne BEVs, (C) soil bacteria, and (D) soil BEVs.
Color is based on Pearson correlation coefficients.
