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.
