Fig. 3.

PD is a good surrogate for FD across clades. The figure presents the distribution and correlates of S_PD–FD for mammals (a–c), birds (d–f) and fishes (g–i) across families. For each of the three groups, the S_PD–FD frequency distribution is presented (b, e) along with its mean (vertical line). The color scheme is common to all panels. S_PD–FD phylogenetic distribution is presented in panels a, d and g. Relationships between S_PD–FD and species pool richness are presented in panels c, f, and i. For each taxonomic family, S_PD–FD values are based on the mean over 1000 repetitions of random and maxPD set draw (there is only one maxFD set).
