Figure 1.
Rank distribution and rank diversity plots.
Hypothetical example showing species ranked by their occupancy or range size (A), and sites ranked by their species richness (B). The area of the blue rectangle equals the number of species (in A) or the total number of sites (in B). Yellow areas measure the unevenness of the range-size (A) or species-richness frequency distributions (B), and the shaded areas are equal to the average species richness of sites (in the plot by species, A) or the average range size of species (in the plot by sites, B).
Figure 2.
Initial conditions of the neutral models described in the text.
Range diversity plots by species (A) and by sites (B) show the values of Schluter's variance ratio index. Vertical dashed lines correspond to the value of ; solid curves show maximum possible values in richness and range size, and shaded areas show the average covariance of species and of sites (from the vertical line outward, limits are covariance +/−0.01, 0.05, 0.1. Rank plots depict the range-size (C) and species richness (B) frequency distributions and the value of Pearson's measure of skewness; colors as in Figure 1.
