Extended Data Fig. 1: Bray Curtis dissimilarities relevant for sample volumetric segments comparisons.

a, The between-group Bray Curtis dissimilarities between each volumetric segments in each households. Each box represents four pairs of comparisons. b, The between and within-group Bray Curtis dissimilarities grouped by sample types. Each box comparing Bray Curtis dissimilarities between different volumetric segments represents 36 pairs of comparisons. Each box comparing Bray Curtis dissimilarities within the same volumetric segment represents 15 pairs of comparisons. In the box plot, the box shows the interquartile range (IQR), which spans from the 25th percentile (Q1) to the 75th percentile (Q3) of the data. The thick line inside the box represents the median of the data. The lower whisker extends from Q1 to the smallest value in the dataset that is greater than or equal to Q1 - 1.5 × IQR (minima); the upper whisker extends from Q3 to the largest value in the dataset that is less than or equal to Q3 + 1.5 × IQR (maxima).
