1. Relative abundance (RA) of individual phyla that are strongly correlated (|rs| = >0.6; q = <0.02) with average soil relative humidity (AvgSoilRH).
Relative abundance (RA) of individual phyla that are strongly correlated (|rs| = >0.6; q = <0.02) with average soil relative humidity (AvgSoilRH). Phyla are listed by decreasing strength of positive correlation (rs = 0.93 to −0.95; Table S4) with RA listed according to the AvgSoilRH of the transect site. Actinobacteria data are negatively correlated (rs = −0.95; q = 2.3 × 10−15) with AvgSoilRH. The heat map is normalized within each phylum to the maximum RA (dark red) for that phylum. Analysis is limited to phyla with site RA = >0.1%. Aridity class labels: H, hyperarid; M, margin; A, arid (as defined in the text).
