Descripción:	In trees, patterns in pollen/seed dispersal and seedling establishment predominantly determine population genetic structure. Pollen dispersal has fundamental evolutionary implications, because it significantly influences genetic processes such as gene exchange among spatially isolated populations. We, thus, hypothesized that seed dispersal by scatterhoarding rodents reaches greater distances than those reported in seed- or fruit-tracking studies. Furthermore, we also hypothesized that pollen-dispersal distances are shorter in high-density stands. To test these hypotheses, we investigated two sites in the southwestern Brazilian Amazon that differ in adult density.
