Extended Data Fig. 2: Differences in bacteria among ecotypes and influencing factors.

(a) Differences in abundance of the nine high-abundance genera across different ecotypes. Box plots show the median (center line), the 25th and 75th percentiles (box limits), and whiskers extending to values within 1.5× interquartile range. (b) Statistical significance levels of the nine high-abundance genera across different ecotypes. Comparisons are made between the former to the latter ecotype. Red squares indicate the former is significantly higher than the latter and the blue indicate the former is significantly lower than the latter (two-sided t-test, *: P-value < 0.05, **: P-value < 0.01, ***: P-value < 0.001, P-values were adjusted by Benjamini-Hochberg method). The yellow boxes represent the enrichment of the nine high-abundance genera across different ecotypes. (c) Relative abundance (size) and coefficient of variation (color) of major bacterial species across different ecotypes. (d) Hierarchical clustering of influencing factors across different ecotypes. (e) Associations among ecotypes and various factors across categories. Red and black indicate enrichment and depletion, respectively (Chi-square test, -: P-value > 0.05, *: P-value < 0.05, **: P-value < 0.01, ***: P-value < 0.001).
