Table 1.
The degree of frugivory of the study species while in tropical latitudes; ‘+’ indicates moderate frugivory, ‘++’ indicates high frugivory, ‘−’ indicates little to no frugivory.
Figure 1.
Frugivore capture rate (all study species except Northern Waterthrush, Eastern Wood-Pewee, Mourning Warbler, Canada Warbler) averaged across all net sites for each of the four sampling periods and associated summed seedless-ripe fruit biomass, across all vegetation plots for each of the four sampling periods in Tortuguero, Costa Rica, 2008.

Linear regression between the first principal component (PCA1) and hourly capture rate of all study species (P = 0.013, adj. R2 = 0.09). Positive PCA1 values are associated with mature forest habitat types.
