Modules analysed in disparity analyses.

% Taxa refers to the number of taxa in which all the traits in a module were significantly correlated. Within-module trait correlations and significance values for each species are detailed in Table A2 of [32], but, as an approximate guide, r = .41 is significant at the p  = .05 level for the average species sample size. Mean r and Upper and Lower CI refers to the mean correlation and 95% confidence intervals among all of the traits in a module, averaged across all species in each clade, as determined by bootstrap analysis (1000 replicates).
