  1. The first two columns provide the gene ontology identifier and description. The third column provides the average of the standardized effect size of the mean pairwise distance values for 630 20 × 20 m subplots. Negative standardized effect size values indicate species with more similar than expected gene set enrichment in response to drought are naturally co-occurring. The fourth column presents the D statistic where a value of 1 indicates phylogenetic signal in the expression data (i.e., consistent with Brownian motion evolution on the phylogeny) and values higher than 1 indicate increasingly labile evolution. The final column presents the p-value for the D statistic
