Seed dispersal distance is more strongly correlated with plant height than with seed mass

Summary 1. It is often assumed that there is a trade‐off between maternal provisioning and dispersal capacity, leading small‐seeded species to disperse further than large‐seeded species. However, this relationship between dispersal distance and seed mass has only been quantified for species from particular sites or with particular dispersal syndromes. 2. We provided the first large‐scale, cross‐species quantification of the correlations between dispersal distance and both seed mass and plant height. Seed mass was positively related to mean dispersal distance, with a 100‐fold increase in seed mass being associated with a 4.5‐fold increase in mean dispersal distance ( R 2 = 0.16; n = 210 species; P < 0.001).…
