There is a consensus about negative impacts of droughts in Amazonia. Yet, extreme wet episodes, which are becoming as severe and frequent as droughts, are overlooked and their impacts remain poorly understood. Moreover, drought reports are mostly based on forests over a deep water table (DWT), which may be particularly sensitive to dry conditions. ...
Este livro reúne 133 artigos publicados em jornais e revistas baseados na mineração de dados existentes no período de 1968 a 2019, que foram recuperados. Debruça-se em sintetizar fatos, sucessos, tendências, padrões e anormalidades, apoiado na experiência e nos resultados de minhas pesquisas e limitado pelo fato de pertencer a uma instituição públi...

Most Asteraceae species are pollinated by insects, mainly bees and butterflies, although pollination by birds has been documented and pollination by bats has been suggested for some species. Here, we investigated the pollination of Gongylolepis martiana, a species supposedly pollinated by bats. We assessed floral traits and visitors in a population...
Rheedia acuminata é espécie frutífera nativa da Amazônia com potencial para consumo in natura. O objetivo do trabalho foi estudar a produção de mudas com adição de matéria orgânica utilizando diferentes concentrações de cama de aviário ao substrato. O experimento foi conduzido no viveiro de produção de mudas do Laboratório de Frutíferas da Embrapa ...
Rodents are important reservoirs of numerous viruses, some of which have significant impacts on public health. Ecosystem disturbances and decreased host species richness have been associated with the emergence of zoonotic diseases. In this study, we aimed at (a) characterizing the viral diversity in seven neotropical rodent species living in four t...
Ongoing deforestation in the Brazilian Amazon is the outcome of an explicit federal project to occupy, integrate, and "modernize" the region. Although there have been isolated periods of deforestation control, most recently between 2004 and 2012, the overall trajectory of the region since the colonial period has been one of forest loss and degradat...
O cumaru (Dipteryx odorata) em sistemas integrados é uma opção de árvore de grande potencial mercadológico. As árvores proporcionam benefícios ao sistema, tanto de ordem técnica, quanto econômica e ambiental. Este estudo objetivou caracterizar a fenologia reprodutiva e vegetativa do Cumarú em sistemas silvipastoris. O estudo foi realizado no Municí...
This article aims to reflect on the strategic importance of hydroelectric energy generated in the Amazon region for the interconnected Brazilian system. Its quantification shows a regional potential for higher energy generation compared to the current production of pre-salt oil. We consider this issue from the perspective of the geopolitics of rene...
Microalgae and cyanobacteria are good sources for prospecting metabolites of biotechnological interest, including glucosidase inhibitors. These inhibitors act on enzymes related to various biochemical processes / they are involved in metabolic diseases, such as diabetes and Gaucher disease, tumors and viral infections, thus, they are interesting hu...
