| ABSTRACT The Amazonian white-sand vegetation presents a set of unique features, such as the dominance of a few species, high endemism and low species richness, which differentiate it from other Amazonian forests. Soil parameters have long been recognized as the main drivers of white-sand vegetation (WSV) characteristics. However, how they influence the composition, richness and structure of this vegetation type is still poorly understood. In this study we investigated the variation in floristic composition between patches and the soil-vegetation relations in three central Amazonian WSV patches. We tested whether slight differences in soil properties are linked with differences in floristic composition, species richness and forest structure in adjacent... |

| ABSTRACT Overexploitation is one of the main causes of biodiversity loss and local extinction. In the Brazilian Amazon, the intensive use of high-value timber species is leading to a decline in their populations. When in decline, these species can be replaced by less valuable and more common ones that are more feasible to exploit. We conducted interviews with residents of two communities in a sustainable development reserve in central Amazonia, and used free lists and the cognitive salience index (S) to assess the perceptions of residents regarding the occurrence and purpose of timber exploitation, and to identify possible endangered species in white-sand and terra-firme forests. In addition, to infer possible consequences of logging, we assessed the... |

| Análises comparativas vêm sendo cada vez mais utilizadas para definir e relacionar os tipos de vegetação existentes no Brasil. Para tanto, cada pesquisador vem montando seu próprio banco de dados, usualmente elaborando um sistema com uma finalidade imediata e descartado ao término do projeto ou pesquisa. Essa prática leva ao desperdício de tempo, esforço, dinheiro e, principalmente, informação. Então, um sistema de banco de dados específico para armazenar e gerenciar informações advindas de levantamentos florísticos e, ou, fitossociológicos poderia padronizar, estruturar logicamente, evitar ou eliminar sobreposição de esforços, reduzir os custos e também promover oportunidade para que cientistas de diversas áreas compartilhem informações. Com esses... |

| ABSTRACT Byrsonima crassifolia and B. coccolobifolia, popularly known as mirixis, muricis, mantecos or nances, are common fruit species in the Amazonian savannas. Their fruits are used in the preparation of juices and other beverages, while the other parts of the plants are used for different purposes in some indigenous communities. The aim of the present ethnobotanical study was to investigate the knowledge and traditional uses of mirixis in the Darora Indigenous Community, of the Makuxi ethnicity, in the São Marcos Indigenous Land, state of Roraima, northern Brazil. The knowledge on these species among the residents was analyzed considering their gender and age. A survey was carried out by means of semi-structured interviews with 60 respondents (36 men... |
