Figure 2: Gut microbial community composition varies among chimpanzee age groups.

Figure 2:

(A) Nonmetric multidimensional scaling (NMDS) ordination plot illustrates differences in gut microbial community composition, based on Bray-Curtis dissimilarities as a factor of age group. Ellipses illustrate standard deviation for age groups. (B) Bray-Curtis dissimilarities between individual chimpanzees and each adult chimpanzee as a factor of age group. (C) Bray-Curtis dissimilarities between individual chimpanzees and other members of their age group, as a factor of age group. Large circles are means; bars show standard deviations. P values reported for (A) PERMANOVA and (B,C) bootstrapped Kruskal-Wallis. * indicates P<0.05 contrast for estimated marginal means of linear mixed effects model.
