  abstract = {{S}eed and pollen dispersal contribute to gene flow and shape the genetic patterns of plants over fine spatial scales. {W}e inferred fine-scale spatial genetic structure ({FSGS}) and estimated realized dispersal distances in {P}hytelephas aequatorialis, a {N}eotropical dioecious large-seeded palm. {W}e aimed to explore how seed and pollen dispersal shape this genetic pattern in a focal population. {F}or this purpose, we genotyped 138 seedlings and 99 adults with 20 newly developed microsatellite markers. {W}e tested if rodent-mediated seed dispersal has a stronger influence than insect-mediated pollen dispersal in shaping {FSGS}. {W}e also tested if pollen dispersal was influenced by the density of male palms around mother palms in order to further explore this ecological process in large-seeded plants. {R}odent-mediated dispersal of these large seeds occurred mostly over short distances (mean 34.76 +/- 34.06 m) while pollen dispersal distances were two times higher (mean 67.91 +/- 38.29 m). {T}he spatial extent of {FSGS} up to 35 m and the fact that seed dispersal did not increase the distance at which male alleles disperse suggest that spatially limited seed dispersal is the main factor shaping {FSGS} and contributes only marginally to gene flow within the population. {P}ollen dispersal distances depended on the density of male palms, decreasing when individuals show a clumped distribution and increasing when they are scattered. {O}ur results show that limited seed dispersal mediated by rodents shapes {FSGS} in {P}. aequatorialis, while more extensive pollen dispersal accounts for a larger contribution to gene flow and may maintain high genetic diversity.{A}bstract in {S}panish is available with online material.},
