LEfSe identified the most differentially abundant genus between island and inland group. a Inland elderly women with enriched taxa are indicated with a positive LDA score (green), and taxa enriched in island elderly women have a negative score (red). Only taxa meeting an LDA significant threshold >2 are shown. b Pearson correlation coefficients among two genera, environmental factors, and host characteristics. Negative correlations are in blue color and positive correlations in red. Correlations are shown in a light (poor correlation) to dark (strong correlation) color scale. Asterisk represents statistical significance (P < 0.05).
