Fig. 5From: Environmental filtering drives distinct continental atlases of soil archaea between dryland and wetland agricultural ecosystemsSpearman correlations between rare phyla and edaphic factors in maize and rice soils, displayed as heatmaps. Scale bars indicate correlation coefficients. Only significant correlations (p < 0.05) are shown.
