Fig. 2. Inter-individual differences in organismal composition and functional potential appear to be preserved, unlike the more variable metatranscriptomes.
a, 1 – Jaccard Index (fraction of shared features) between all possible pairwise combinations of the first faecal sample with the other three samples collected from each individual (n = 308). 95% confidence intervals are shown in grey. b, Bray–Curtis β-diversity scores within and between subjects for short- (24–72 h; n = 308 individuals) and intermediate-term intervals (6 months; n = 160 individuals). Here, species represents taxonomic profile abundances, DNA represents metagenomic functional profiles, and RNA represents metatranscriptomes. Boxplot whiskers include observations within 1.5 interquartile range of the upper and lower quartiles.
