Training Area

The aim of this study was to characterize the sandfly fauna in a military training area situated in the "Zona da Mata" region of Pernambuco State, Brazil, where human cases of American tegumentary leishmaniasis (ATL) had been observed, caused by Leishmania (Viannia) braziliensis. The occurrence of 16 sandfly species in the Marshall Newton Cavalcanti Military Training Camp (CIMNC) indicates an important diversity of sandfly species in this study area. Lutzomyia complexa was the most common species (51.36%) followed by L. choti (43.54%). All the captures were made in areas where training activities were conducted and where clinical cases had been detected in individuals performing training, following this period. The data relating the sandfly behavior to previous data in the same area provides strong evidence for the occurrence of an enzootic cycle of the parasite, and outbreaks followed the period of training activities in the remaining Atlantic Rain Forest and secondary forest areas.

I. Atlantic Rain Forest . Ecological Station Juréia-Itatins) Crude extracts from 88 plant species occurring in São Paulo State (Brazil), collected in an Atlantic Forest region, have been screened for antimicrobial and DNA-damaging activities. Of the 114 extracts assayed for antibacterial activity, only the extracts from leaves and stems of Aspidosperma ramiflorum (Apocynaceae) showed a slight activity against Escherichia coli. In the antifungal assay with Candida albicans, no active extract was observed, while in the bioautography assay with Cladosporium sphaerospermum and C. cladosporioides 12% were active. However, only the extract of Psychotria mapoureoides (Rubiaceae) stems showed a strong inhibition of both fungi. The DNA-damaging assay with mutant strains of Saccharomyces cerevisiae resulted in 17.5 % of active extracts. The majority (55 %) of the active extracts showed selectivity for the DNA-repair mechanism of topoisomerase II and only 20 % showed a selective response for the mechanism of topoisomerase I.

AbstractPalynological analysis of a core from the Atlantic rain forest region in Brazil provides unprecedented insight into late Quaternary vegetational and climate dynamics within this southern tropical lowland. The 576-cm-long sediment core is from a former beach-ridge “valley,” located 3 km inland from the Atlantic Ocean. Radio-carbon dates suggest that sediment deposition began prior to 35,000 14C yr B.P. Between ca. 37,500 and ca. 27,500 14C yr B.P. and during the last glacial maximum (LGM; ca. 27,500 to ca. 14,500 14C yr B.P.), the coastal rain forest was replaced by grassland and patches of cold-adapted forest. Tropical trees, such as Alchornea, Moraceae/Urticaceae, and Arecaceae, were almost completely absent during the LGM. Furthermore, their distributions were shifted at least 750 km further north, suggesting a cooling between 3°C and 7°C and a strengthening of Antarctic cold fronts during full-glacial times. A depauperate tropical rain forest developed as part of a successional sequence after ca. 12,300 14C yr B.P. There is no evidence that Araucaria trees occurred in the Atlantic lowland during glacial times. The rain forest was disturbed by marine incursions during the early Holocene period until ca. 6100 14C yr B.P., as indicated by the presence of microforaminifera. A closed Atlantic rain forest then developed at the study site.
