L.  aSpatial genetic structure, genetic diversity and pollen dispersal in a harvested population of Astrocaryum aculeatum in the Brazilian Amazon.h[electronic resource]  c2016  aAstrocaryum aculeatum is a palm tree species native to the tropical regions of South America, exploited commercially by local farmers for the pulp extracted from its fruits. The objective of this research was to compare the genetic diversity between adult plants and seedlings from open-pollinated seeds, quantify the pollen flow and dispersal, the spatial gene tic structure, and the effective size of a population that has been continuously harvested for its fruits. The study was carried out in a natural population of A. aculeatum distributed over approximately 8 ha in the State of Amazonas (Brazil), separated by 400 m from the closest neighboring population. In total, 112 potential pollen donors, 12 mother plants and 120 offspring were mapped and genotyped.  aAstrocaryum aculeatum  agene flow  apopulation genetics  aCoancestry coefficient  aDiversidade genética  aEffective size  aEstrutura genética espacial  aMicrosatellites  aPaternity analysis  aTucumã of amazonas1 aDEQUIGIOVANNI, G.1 aSEBBENN, A.
