Conteúdo: |
Among globally important wetlands, the Pantanal stands out because of it's a history of harmonious coexistence of man and biodiversity. In the recent years, however, severe human impacts have emerged, which are capable of disintegrating Pantanal?s natural characteristics. This paper contributes to the development of a sustainable management concept considering ecological and socioeconomical demands. Use of natural resources in the highly productive catchment of the tributaries have direct effects on the floodplains of the Pantanal. A careful planning of hydropower plants is needed to maintain (a) some of the tributaries remaining open for fish spawning migration, and (b) the natural flood pulse as the overriding ecological factor. The traditional human population of the Pantanal is threatened by the developments of global change. Their knowledge to use floodplain-specific species is very important for developing sustainable use strategies. Several positive initiatives are highlighted, including the development of a green seal for Pantanal beef and the re-establishment of gallery forests along tributaries. The sustainable use of the fish ressources requires a precise analyis of the stock dynamics. For the further development of the sustainable use, a classification system is needed, which specifies the use potential and conservation demands of the individual habitats. |

Background: Brazil nut is a protein-rich extractivist tree crop in the Amazon region. Fungal contamination of shells and kernel material frequently includes the presence of aflatoxigenic Aspergillus species from the section Flavi. Aflatoxins are polyketide secondary metabolites, which are hepatotoxic carcinogens in mammals. The objectives of this study were to identify Aspergillus species occurring on Brazil nut grown in different states in the Brazilian Amazon region and develop a specific PCR method for collective identification of member species of the genus Aspergillus. Results:Polyphasic identification of 137 Aspergillus strains isolated from Brazil nut shell material from cooperatives across the Brazilian Amazon states of Acre, Amapá and Amazonas revealed five species, with Aspergillus section Flavi species A. nomius and A. flavus the most abundant. PCR primers ASP_GEN_MTSSU_F1 and ASP_GEN_MTSSU_R1 were designed for the genus Aspergillus, targeting a portion of the mitochondrial small subunit ribosomal RNA gene. Primer specificity was validated through both electronic PCR against target gene sequences at Genbank and in PCR reactions against DNA from Aspergillus species and other fungal genera common on Brazil nut. Collective differentiation of the observed section Flavi species A. flavus, A. nomius and A. tamarii from other Aspergillus species was possible on the basis of RFLP polymorphism. Conclusions:Given the abundance of Aspergillus section Flavi species A. nomius and A. flavus observed on Brazil nut, and associated risk of mycotoxin accumulation, simple identification methods for such mycotoxigenic species are of importance for Hazard Analysis Critical Control Point system implementation. The assay for the genus Aspergillus represents progress towards specific PCR identification and detection of mycotoxigenic species.
