Figure 2. Principal Coordinates Analysis of the dissimilarity of microbial communities of the 32 samples.

Dissimilarities were calculated using the UniFrac metric based on a re-sampling size of 250 sequences. Individual samples are indicated by small symbols and each halo indicates the variability calculated from Jackknife re-sampling. Different symbol colours and shapes represent different sample categories: (green ▴) female, (blue ▪) child, (yellow ◂) male, (red ▸) cattle, (orange •) chimpanzee and (lilac ▾) keeper.
