Figure 3 | Dispersal across the landscape. Seed dispersal kernels of (a) Psychotria and (b) Premna on Guam as compared with three nearby islands where forest birds are present. The ﬁtted kernel models were used to predict seed rain in a hypothetical forest plot. Panels c,d depict seed rain in forests with frugivores, and panes e,f depict seed rain in forests without frugivores. Shading indicates the mean seed density (seeds m - 2, note logarithmic scale) arriving at each location on the forest ﬂoor. Circles indicate crowns of conspeciﬁc adult trees.
