Results of a research on the macroeconomic dynamics of the Amazon region, in the eighties, that turned unfeasible the traditional agricultural extensive system, which remained so far, and started to demand constant increase in productivity, from the sector, as well as price reduction and better quality of products, without loss of preservation and conservation of the ecosystem. Based on this premise this study was directed to the analysis of the agroforestry production system experiments, carried out by a partnership research with the SHIFT-project, in areas of the Embrapa Amazonia Ocidental (Manaus-AM), with the objective of determining alternatives that could contribute to sustainable development for the Amazon region. The analysis of these systems, among others, indicated that results of the research may contribute to the sustainability of the region environment, mainly in comparison with the existent traditional systems. |

Abstract: The aim of this study was to access the genetic diversity and relatedness between Canindé and British Alpine goat breeds in the States of Piauí and Ceará using microsatellite markers. Genomic DNA was isolated from hair samples of 99 goats belonging to six different flocks. A panel of polymorphic heterologous microsatellite loci was used to genotype individuals. The microsatellite markers resulted in a total number of 145 alleles, with an average of 8.5 alleles per locus. The observed and expected heterozygosities were ?0.687 and ?0.627, respectively, for all loci. The polymorphic information content showed that all loci were highly informative with an overall mean of 0.757. Overall FST across all populations and loci was 18%, which was consistent with the coefficient of gene differentiation (GST = 0.104). AMOVA revealed that 12.8% of the variation was captured between breeds. The Bayesian STRUCTURE clustering detected the maximum likelihood for a model of two genetically distinct groups, in agreement with the number of predefined studied breeds and the two-dimensional plot from the PCoA analysis. The exotic British Alpine breed and the naturalized Brazilian Canindé breed were clearly differentiated by the microsatellite markers, indicating that these two breeds have distant genetic identities, despite the phenotypic similarity.enotype individuals. |
