Figure 1 Phylogenies of 500 randomly selected species from the dataset of 9370 species. (a) 1-threshold, the full time scale phylogeny; (b) 0.67-threshold, the same phylogeny but when nodes above the 0.67 threshold (i.e., nodes in the top 1/3 of the phylogeny) are collapsed to remove the ”recent” phylogenetic relationships; and (c) 0.40-threshod, phylogeny with nodes above the 0.40 threshold are collapsed. The 0.67 threshold corresponds roughly to taxonomic families. The full dataset of 9370 species was subsampled for better visualization.
Figure 2 Distribution of fleshy-fruited versus dry-fruited species in different (a) climate regions, (b) growth forms and (c) phylogeny, and (d) the contribution of different factors to the variation in fruit type. Numbers in (a) and (b) are number of species for each fruit type.
Figure 3 The values of R2likfor phylogenetic models of each trait separately as ”recent” phylogenetic relationships are removed from the full phylogeny. ”Threshold” is the level in the full phylogeny above which nodes are collapsed; see Fig. 1 The age for each threshold was shown in the parentheses.
