Data for this study were taken from a 500 ha experimental plot in a dense terra firme forest in the Eastern Brazilian Amazon and included the mapping and genotyping of 161 reproductive trees, representing more than 90% of all adult trees, and the collection of 748 open-pollinated seeds from 56 seed-trees over two field seasons (2002 and 2003). High levels of pollen immigration from outside of the study plot were detected in both sampled seed-years (?49%) suggesting long distance pollen gene flow. Low levels of self-fertilization were also detected (?2%). The analysis showed long distance pollen dispersal occurred within the study area in both 2002 (? = 907 ± 652 m SD) and 2003 (? = 963 ± 542 m SD). Patterns of pollen dispersal distance within the plot were also found to be shorter than the distances between potential male parents and seed-trees. This result indicates that the distance between trees does not explain the identified pollen dispersal pattern. Our results support the hypothesis that animal pollinated species occurring in low-density populations can disperse pollen in long distances, despite the very dense nature of the forest.  aAmazonia  aDispersão  aPólen  aSymphonia Globulifera  aBrasil1 aDEGEN, B.1 aKANASHIRO, M.1 aLACERDA, A.
