The effects of masting on rodent-mediated seed dispersal interaction of sympatric tree species

•Indirect seed-seed interactions in response to masting are largely overlooked.•We investigated how masting regulates seed-seed interactions of sympatric tree species.•Our results showed species-specific masting effects on seed dispersal of sympatric trees.•Masting of tree species influenced each other’s seed dispersal via indirect seed-seed interactions.•Preference for seed traits by predators may regulate masting effects on seed dispersal.
