The h and I diversity indices ranged respectively from 0.16 to 0.24 in the PAD (Parque das Dunas) population and from 0.21 to 0.29 in MAC (Macaíba) population. The mean genetic diversity of Nei (h) was 0.19, and the Shannon index (I) was 0.27.

The ISSR (Inter-Simple Sequence Repeat) markers provided 70 loci, of which 81% were polymorphic. speciosa, distributed in seven populations. The objective of this study was to evaluate the genetic diversity in natural populations of Hancornia speciosa and to contribute to the development of conservation strategies. Genetic diversity is fundamental to the survival of species in natural environments in the long term, as well as being the basis for genetic improvement. The continuing fragmentation of forests has been a threat to the maintenance of genetic resources. Also, further recovery of degraded areas in the vicinity and ex Genetic bottleneck, and the low average genetic diversity detected. In situ conservation strategies must be adequately maintained considering the current isolation of studied populations, the

Genetic bottleneck tests indicated that all populations presented significant reductions in the population Bayesian analysis revealed the existence of two distinct genetic groups, in which the MAC (Macaíba) population was AMOVA indicated higher genetic variation among individuals within populations than among The average number of alleles was 1.59, the effective number of alleles was 1.34, Nei’s genetic diversity was 0.20,Īnd the Shannon index was 0.30. We sampled 64 individuals in this study, for which seven primers used generated 90 loci, with 93% being Thus, the objective of this study was to evaluate the genetic diversity of Protium heptaphyllum (Burseraceae) tree species in Support strategies for preserving the genetic resources, and the data to date for the Atlantic Forest in northeast Brazil is scarce. Fragmentation leads to changes in the size and dynamics of forest populations.
