The genetic diversity and divergence between the studied populations indicated that the Pedregulho population should be considered an Evolutionary Significant Unit and a Management Unit.Īlmeida SP, Proença CEB, Sano SM, Ribeiro JF (1998) Cerrado: espécies vegetais úteis. Gene flow was high enough to counter the effects of genetic drift. Estimates of effective population size were low (<10), and the minimum viable area for conservation in the short-, medium- and long-term was estimated to be between 4 and 184 ha. The influence of the Wahlund effect on the studied populations lies between 8.5 and 53.3 %. Spatial structure was observed in the distribution of specimens in distance classes ranging from 30 to 40 km and three genetic clusters were identified, with genotypes in the Pedregulho population differing from the others by up to 90 %. All populations departed from Hardy–Weinberg equilibrium ( p < 0.05). An excess of homozygotes and moderate levels of inbreeding were observed. Alleles private to particular populations and rare alleles were also detected. Results indicated a mean number of 12 alleles per locus, but only six effective alleles. Eight microsatellite loci were used to analyze samples from four populations subjected to different types of anthropic pressure, distributed throughout the state of São Paulo in the regions of Assis, Brotas, Itirapina and Pedregulho. We analyzed the genetic structure and diversity of Qualea grandiflora Mart., the most abundant woody species in the Brazilian Cerrado.
