Figure 2.

Overlap in seed dispersal services provided by flying foxes and other fruit-eating animals in Tonga. The figure shows the number of plant species that are dispersed (black) or destroyed (grey) by (A) flying foxes and how many of these species are also consumed by other animals (B–E). Dispersed species are arranged into four categories of diaspore size: small (S < 4 mm), which is the gape limit of flying foxes; medium (M = 4–13 mm), which is the gape limit of small birds; large (L = 14–27 mm), which is the gape limit of pigeons and extra large (XL > 27 mm) cannot be swallowed by anything (cf. Meehan et al. 2002).
