Microsatellite diversity and effective population size in a germplasm bank of Hymenaea courbaril var. stilbocarpa (Leguminosae), an endangered tropical tree: recommendations for conservation

“…This value is comparable to the patterns observed for other tropical tree species, with values from 2 to 7 (James et al 1998;Rocha and Aguilar 2001;Dunphy et al 2004;Moraes et al 2004;Azevedo et al 2007;Carneiro et al 2007), and is similar to those detected for other populations of H. courbaril, where the number of pollen donors, estimated by paternity analysis, was determined to be 6.9 in Costa Rica (Dunphy et al 2004) and 4 in the Brazilian Amazon (Lacerda et al 2008a). …”

“…Bawa (1974) and Jansen (1983) report this species to be self-incompatible. Studies by Dunphy et al (2004) and Lacerda et al (2008a) use genetic markers to demonstrate that H. courbaril is perfectly outcrossed, confirming the results of Bawa (1974) and Jansen (1983). According to Gibbs et al (1999), this apparent incompatibility may result from post-pollination events.…”

“…Dunphy et al (2004), studying a H. courbaril population in Costa Rica, and Lacerda et al (2008a) studying a population in Brazil's Amazon region, described this species as perfectly outcrossed (t m ¼ 1) and probably self-incompatible. Self-incompatible systems have been described in many tropical tree species (Cascante et al 2002;Fuchs et al 2003;Lobo et al 2005); this system of mating prevents inbreeding due self-fertilization and, consequently, inbreeding depression.…”

Effects of Reduced Impact Logging on genetic diversity and spatial genetic structure of a Hymenaea courbaril population in the Brazilian Amazon Forest

“…Inbreeding in a hermaphrodite species such as H. courbaril could occur by self-fertilization and mating among relatives (biparental inbreeding). However, the mating system analysis showed an absence of self-fertilization, suggesting that the species is self-incompatible (Lacerda, 2007;Dunphy et al, 2004). Additionally, the population has a strong spatial genetic structure in the reproductive stages and near-neighbour trees Fig.…”

Brief Note Mendelian inheritance, linkage and genotypic disequilibrium in microsatellite loci isolated from Hymenaea courbaril (Leguminosae)

“…Investigations about the impacts of forest logging on the genetic diversity, mating system and gene flow using genetic markers, are very important for the development of species' appropriate sustainable logging practices. For H. courbaril, such studies have recently started (Dunphy et al, 2004;Lacerda et al, 2008a,b;Sebbenn et al, 2008) after the development and characterization of a set of polymorphic microsatellite loci for the species (Ciampi et al, 2000). However, to ensure the appropriate use of these loci for genetic analyses of H. courbaril populations, it is important to verify if the microsatellite loci display Mendelian inheritance and if they are associated.…”
