Figure 3

Differences in the microbial communities. (a) Rarefaction curves of the bacterial communities associated with 4 purple damaged (#EP) and 3 uncolored undamaged (#AW) samples of the parchment. Bray Curtis dissimilarity: (b) UPGMA tree of the purple damaged (#EP) and uncolored undamaged (#AW) samples (UniFrac.weighted, WScore = 1; WSig = <0.001). The UniFrac methods describe whether two or more communities have the same structure. The significance of the test statistic indicates the probability that the communities have the same structure by chance. The value does not indicate a level of similarity.
