Sorocea bonplandii is a dioecious sub canopy plant species with an abundant and widespread distribution
in the Atlantic Forest, Southern Brazil. It is traditionally used for art crafts and popular medicine. We have
investigated the genetic status of S. bonplandii in one large and six small populations of the fragmented
Atlantic Forest in southern Brazil. In spite of population fragmentation, the allozyme electrophoretic analysis
involving 23 loci of 12 enzymes from 420 plants revealed unusually high frequencies of heterozygous
genotypes and a balanced distribution, in agreement with Hardy-Weinberg proportions. Very little genetic
differentiation among populations was detected. The observed excess of heterozygotes suggests that selection
favors heterozygous plants. Although S. bonplandii is a dominant sub-canopy species which strongly
depends on ombrophilous environmental conditions, its genetic structure and diversity do not appear to
suffer with forest fragmentation. All of these characteristics, in addition to its medicinal uses, suggest that
this species is a potential resource for sustainable management of tropical forests in southern Brazil. |
