Associations between gene distribution features (GDFs) and taxa-function robustness. a Pearson correlations between GDFs and attenuation; blue and red bars indicate significant (p < 0.01) positive and negative correlation coefficients, respectively, whereas gray bars show non-significant correlation coefficients. Each panel corresponds to correlations when considering communities from all environments (pooled) or the subset of communities from a particular environment. b Communities plotted by the first two principal components (PCs) determined by principle component analysis (PCA) of the five GDFs. The percent variance explained by each PC is indicated on the axis labels. Loadings for GDFs are indicated by the direction and magnitude of the labeled vectors. Communities were binned along both axes, and the density of attenuation values is displayed by the width of the violin plots in the plots along the top and right margins of the PCA plot. Dots indicate the median attenuation of communities in each bin
