We examined predispersal granivory in common and rare bird-dispersed plants in two tropical and two temperate communities. Our results show that the prevalence and intensity of predispersal granivory are higher in tropical communities and for smaller seeds. Results also show no effect of plant species’ relative abundance on granivory. Abstract in Spanish is available with online material.
