Additional file 10: Figure S9. of Interpreting Prevotella and Bacteroides as biomarkers of diet and lifestyle

NMDS plots using the Bray distance metric with only the Yatsunenko study. A) Samples colored by their most prominent taxon. If the sample is dominated neither by Prevotella nor Bacteroides, it is classified as other. B) Samples are colored by their value for the Prevotella ratio (relative abundance of Prevotella/[Bacteroides + Prevotella]) on a spectrum with red indicating no Prevotella and purple no Bacteroides. C) Samples are colored by population of origin. D) The Bray distance has been recalculated without the relative abundances of Bacteroides and Prevotella. Samples are colored by most prominent taxon in the original samples distributions (same as in plot A). (PDF 28 kb)
