Figure 3.
Increased sharing of bacterial phylotypes by sympatric hosts. Principal coordinates plots show the first two principal coordinates of the pairwise binary Bray-Curtis dissimilarities (A) and unweighted UniFrac distances (B) among hosts. Shown are the mean values for each sample calculated from rarefaction analyses. Samples are colored by the population from which they were collected corresponding to Figure 1. Note that sympatric Pan individuals cluster more closely with Gorilla individuals than do isolated Pan individuals.
