Fig. 4: Beta diversity indices.

Unconstrained principal coordinates analysis (PCoA) of Bray–Curtis (a) and Jaccard (b) indices (genus-level) in mouse populations in standing (DNA-based) and active (RNA-based) communities. Goodness of fit of mouse origin: Bray–Curtis axes, R2 = 0.49, p = 10−5, Jaccard: R2 = 0.62, p = 10−5, based on 105 permutations. “+” centroid of the cluster.
