  abstract = {{A}im {L}ong-distance dispersal has contributed to the disjunct biogeographical distribution of rain forest plants-something that has fascinated biogeographers since {H}umboldt's time. {H}owever, the dispersal agent for these tropical plant lineages remains puzzling. {H}ere, we investigate which frugivory-related traits may have facilitated past intercontinental long-distance dispersal in the custard apple family ({A}nnonaceae), a major vertebrate-dispersed tropical plant family. {W}e hypothesize that long-distance dispersal was associated with the evolution of traits related to dispersal by large-bodied mammals (e.g., large, dull-coloured, "megafaunal" fruits) and strong-flying, ocean-crossing birds and bats (e.g., dehiscent, moniliform or cauliflorous fruits). {L}ocation {G}lobal. {T}axon {A}nnonaceae. {M}ethods {W}e used a fossil-calibrated phylogenetic framework to infer the biogeographic history of 234 {A}nnonaceae species (10%, covering nearly all genera) in relation to the evolution of 15 frugivory-related traits, using maximum likelihood and {B}ayesian inferences. {F}urthermore, we used linear and generalized linear models and phylogenetic simulations to test whether ancestral fruit traits during intercontinental dispersal were different from those of other lineages not involved in long-distance dispersal. {R}esults {W}e inferred the ancestral {A}nnonaceae fruits to be small with a single or few small seeds and a small number of fruitlets. {T}hese fruits were most probably apocarpous, indehiscent and/or moniliform (i.e., long beads of fruitlets). {F}urthermore, most of the long-distance dispersal events in {A}nnonaceae occurred via the expanded tropical forests in the {E}arly {C}enozoic ("geodispersal"), and were significantly associated with large (c. 3 cm long), dull-coloured fruits and short stipes. {A}dditionally, long-distance dispersal was also facilitated by dehiscent, moniliform and non-cauliflorous fruits. {M}ain conclusions {W}e suggest that the evolution of frugivory-related traits associated with dispersal by frugivores that frequently move across large distances and/or barriers, such as large-bodied mammals and strong-flying birds, has contributed to the disjunct tropical biogeographical distribution of {A}nnonaceae, and probably of tropical rain forest plants more generally.},
