The LEfSe identified the most differentially abundant genera within the suburban (> 1.1 µm, red), suburban (< 1.1 µm, green), urban (> 1.1 µm, blue), and urban (< 1.1 µm, purple) groups. NA, not assigned. Totally 23 bacterial genera were considered significant. The threshold for the logarithmic LDA score is 2, with a p-value of < 0.05.
