摘　　要：Reproduction by perennial plants varies from being relatively constant over years to the production of massive and synchronous seed crops at irregular intervals,a reproductive strategy called mast seeding.The sources of inter-specific differences in the extent of interannual variation in seed production are largely unknown.We conducted a global meta-analysis of animal-dispersed species to quantify how the interannual variability in seed crops pro-duced by plants can be explained by the seed mass,dispersal mode,phylogeny,and climate.Phylogenetic analysis indicated that the interannual variations in seed production and seed mass tended to be similar in related species due to their shared evolution.The interannual variation in seed production was 1.22 times higher in synzoochorous species dispersed by scatter-hoarders compared with endozoochorous species dispersed by frugivores.Further-more,the production of small seeds was associated with higher interannual variation in seed production,although synzoochorous species produced larger seeds than endozoochorous species.Precipitation rather than temperature had a significant positive effect on the interannual variation in seed production.The seed mass and dispersal mode contributed more to the interannual variation in seed production than phylogeny,climate,and fruit type.Ourfind-ings support a long-standing hypothesis that interspecific variation in the masting intensity is largely shaped by interactions between plants and animals.
