13. Entomopathogenic fungi and their potential for the management of Aedes aegypti (Diptera: Culicidae) in the Americas
Classical biological control has been used extensively for the management of exotic weeds and agricultural pests, but never for alien insect vectors of medical importance. This simple but elegant control strategy involves the introduction of coevolved natural enemies from the centre of origin of the target alien species. Aedes aegypti - the primary vector of

14. Geochemical Signature of Amazon Tropical Rainforest Soils
ABSTRACT: Evaluating soil geochemical diversity in the Amazon Basin has been a challenge largely because most study sites have been at the edge of the basin and it is difficult to get samples in such a region. Here we show that even among the most weathered soils, physicochemical soil properties express lithology. Our results are based on topsoil samples col

15. Vegetation structure, carbon sequestration potential and species conservation in four agroforestry systems in Cameroon (Tropical Africa)
ABSTRACT As the rate of forest degradation continues to rise, agroforestry may serve as a way of conserving species and carbon sinks. The aim of this study was to assess agrobiodiversity and carbon sequestration potential in agrosystems in Cameroon. Three age groups of agrosystems were studied. Data were collected in 100x50 m2 quadrates. Density ranged from

16. Paraparesia espástica tropical - abordagem anestésica
Resumo Introdução A infecção por HTLV- 1 é endêmica no Japão, nas Caraíbas, na África e na América do Sul. A transmissão ocorre de mãe para filho, por contatos sexuais, transfusões de sangue ou partilha de agulhas. A essa infeção está associada uma doença neurológica degenerativa crônica, a paraparesia espástica tropical (TSP). Essa resu

18. Com o diabo no corpo: os terríveis papagaios do Brasil colônia
RESUMO Desde a Antiguidade, papagaios, periquitos e afins (Psittacidae) fascinaram os europeus por seu vivo colorido e uma notável capacidade de interação com seres humanos. A descoberta do Novo Mundo nada faria além de acrescentar novos elementos ao tráfico de animais exóticos há muito estabelecido pelos europeus com a África e o Oriente. Sem possui

21. Mapping of courses on vector biology and vector-borne diseases systems: time for a worldwide effort
Major emergency efforts are being mounted for each vector-borne disease epidemiological crisis anew, while knowledge about the biology of arthropods vectors is dwindling slowly but continuously, as is the number of field entomologists. The discrepancy between the rates of production of knowledge and its use and need for solving crises is widening, in particu

22. The role of natural selection in human evolution – insights from Latin America
Abstract A brief introduction considering Darwin's work, the evolutionary synthesis, and the scientific biological field around the 1970s and subsequently, with the molecular revolution, was followed by selected examples of recent investigations dealing with the selection-drift controversy. The studies surveyed included the comparison between essential genes

24. ENTRE O DISCURSO SOLIDÁRIO E A AÇÃO PRAGMÁTICA DA COOPERAÇÃO BRASILEIRA EM MOÇAMBIQUE: os casos dos projetos de implantação da fábrica de medicamentos antirretrovirais e o ProSavana
A cooperação brasileira com países africanos ganhou importante relevo ao longo do governo de Lula da Silva, apoiada pelo discurso da solidariedade internacional e da existência de uma dívida histórica com a África, bem como por uma prática que busca, sobretudo, estruturar setorialmente as demandas desses países, sem impor condicionalidades. Percebe-
