Trait bins and summary statistics. Details on trait groups used to map trait data onto phylogenies along with the number of taxa included in each phylogeny, the minimum and maximum values and associated taxon name for each trait, along with mean trait values. Additional details on trait values by taxon can be found in Table S2
