1. Unweighted UniFrac PCoA plots.
Unweighted UniFrac PCoA plots. (A) Combined data from the present Atacama Desert study and from Fierer et al. (19). (B to E) Atacama-only data. (A) Samples colored by their geographic origins. (B to F) Samples colored by soil properties, where light colors indicate the low end of the specified range and dark colors indicate the high end of the specified range. These data illustrate statistical results presented in Table S3, specifically, that average soil relative humidity is a better predictor of sample composition in the Atacama Desert than high soil temperature, electrical conductivity, or pH.
