Forest logging reduces population density and increases the distance between co-specifics and so can cause the loss of alleles, and affect the genetic diversity, spatial genetic structure (SGS), mating system, and pollen flow of the population. These factors were studied in the tropical tree species Bagassa guianensis Aubl. occurring in a low-density population in the Brazilian Amazon forest. Genetic diversity was compared among offspring, juveniles and adult trees, before and after selective logging. Non-significant differences were observed between these samples. The harvest of 61% of the adult trees caused the loss of three alleles in the reproductive population. However, these alleles were present in juveniles and offspring and so were not lost from the population. SGS was detected up to 300 m before logging in the overall and adult populations. After logging, significant SGS was not observed. Deviations from random matings were evident throughout biparental inbreeding (View the MathML source1?t?s=0.067, P < 0.05), correlated mating (View the MathML sourcer?p(m)=0.193, P < 0.05), and differentiation in pollen gene pool (View the MathML source??ft=0.081, P < 0.05). The effective number of pollen donors was estimated as 5?7 trees. The distance of pollen gene dispersal was estimated as 308?961 m, depending on the dispersal model used (normal and exponential) and assumed population density. The estimated neighbourhood pollination area (Aep) ranges from 81 to 812 ha, depending also on the assumed population density. Reproduction by obligatory outcrossing, pollen immigration from trees outside of the plot, the long-pollen dispersal distance, and large Aep suggested that the species can be resilient to the impacts of logging.
