Contemporary pollen and seed dispersal in natural populations of Bertholletia excelsa (Bonpl.).
Due to the nutritional content and commercial value of its seeds, Bertholletia excelsa is one of the most important species exploited in the Amazon region. The species is hermaphroditic, insect pollinated, and its seeds are dispersed by barochory and animals. Because the fruit set is dependent on natural pollinator activity, gene flow plays a key role in fruit production. However, to date, ther...
متن کاملDiversity and genetic structure of the native Brazil nut tree (Bertholletia excelsa Bonpl.) population.
The present study was carried out in a native Brazil nut tree population (Bertholletia excelsa Bonpl., Lecythidaceae) to assess its genetic diversity and structure. Ten microsatellite markers were used to genotype 198 adult trees (B. excelsa). The population presented high genetic diversity and inbreeding absence rates. The empirical Bayesian method showed three distinct groups in the structure...
متن کاملConstruction of Brazil nut (Bertholletia excelsa: Lecythidaceae) cambium normalized cDNA libraries for 454 next generation sequencing
Background The Brazil nut, Bertholletia excelsa (Lecythidaceae), is the most important non-timber forest resource in the Amazonian biome, where nuts for the international trade are exclusively wild-collected. The monotypic genus possesses a discontinuous distribution and is thought to have rapidly and recently radiated south and westward from a northern/eastern Amazonian origin, largely as a re...
متن کاملIsolation and characterization of microsatellite markers for Bertholletia excelsa (Lecythidaceae) population genetic analysis.
Seven polymorphic microsatellite markers were developed and validated for Bertholletia excelsa (Brazil nut tree) population genetic studies. This species is a widespread monotypic Amazonian tree with high non-timber economic value. Unfortunately, Brazil nut production is currently less than 25% of historical production levels, because of extensive deforestation. All pairs of primers produced cl...
متن کاملNut Production in Bertholletia excelsa across a Logged Forest Mosaic: Implications for Multiple Forest Use
Although many examples of multiple-use forest management may be found in tropical smallholder systems, few studies provide empirical support for the integration of selective timber harvesting with non-timber forest product (NTFP) extraction. Brazil nut (Bertholletia excelsa, Lecythidaceae) is one of the world's most economically-important NTFP species extracted almost entirely from natural fore...
