ABSTRACT
Genetic structure data of five populations of the Luehea divaricata Mart. & Zucc., forest tree species under
development in the Atlantic Forest biome, obtained by microsatellite DNA markers,
were used in simulations to study their reproductive and ecological pattern.
Different selfing and migration rates were tested, using the observed and
expected heterozygosity of 0.55 and 0.67, respectively, obtained through the
use of microsatellite markers. Closest values were obtained with the use of
selfing rates of 0.3 and migration of 0.2. These results suggest the presence
of some self-incompatibility system between these species, which reduces, but
does not prevent the self-fertilization. The migration rate contributes to a
low genetic differentiation between the populations, making the reproductive
mode, responsible for the inbreeding observed in the same populations. Authors suggest continuous
monitoring of the genetic variability as a guarantee for the persistence of
these populations. The study focus on the importance of using computer
simulations to investigate ecologic, reproductive and genetic patterns for
forestry populations, thus enabling the application of suitable measures for
conservation.
