Fig. 2.

PD is a good surrogate for FD across geographical areas. The figure presents the distribution and correlates of S_PD–FD for mammals (a–c), birds (d–f), and tropical fishes (g–i) separately across space. For each of the three groups, the S_PD–FD frequency distribution is presented in top panels (b, e, h) along with its mean (vertical line). The color scheme is common to all panels, with blue indicating positive S_PD-FD (maximizing PD captures more FD than random) and red indicating negative S_PD–FD. S_PD–FD geographical distribution is presented in middle panels (a, d, g). Relationships between S_PD–FD and species pool richness are presented in panels c, f, i. In each grid cell, S_PD–FD values are based on the mean over 1000 repetitions of random and PDmax set draw (there is only one maxFD set). The maps in this figure were generated making use of the R-package rasterVis and latticeExtra. The animal silhouette images in this figure were created by the corresponding author in Adobe Acrobat
