Eficácia da aplicação do mĂ©todo estatĂstico aos fenĂ´menos de vida referentes ao homem
O presente trabalho representa mais uma tentativa por parte dos autores em demonstrar, em nosso meio, o valor que pode assumir o mĂ©todo estatĂstico, quando aplicado aos fenĂ´menos de vida referentes ao homem. Embora a parte material tenha sido principalmente elaborada por um de nĂłs, (Pedro Egydio), as idĂ©ias que vĂŁo ser expendidas vĂŞm sendo propugnadas pelos autores há já longo tempo e sistematicamente postas em prática em suas publicações

BioTIME: A database of biodiversity time series for the Anthropocene.
MotivationThe BioTIME database contains raw data on species identities and abundances in ecological assemblages through time. These data enable users to calculate temporal trends in biodiversity within and amongst assemblages using a broad range of metrics. BioTIME is being developed as a community-led open-source database of biodiversity time series. Our goal is to accelerate and facilitate quantitative analysis of temporal patterns of biodiversity in the Anthropocene.Main types of variables includedThe database contains 8,777,413 species abundance records, from assemblages consistently sampled for a minimum of 2 years, which need not necessarily be consecutive. In addition, the database contains metadata relating to sampling methodology and contextual information about each record.Spatial location and grainBioTIME is a global database of 547,161 unique sampling locations spanning the marine, freshwater and terrestrial realms. Grain size varies across datasets from 0.0000000158 km2 (158 cm2) to 100 km2 (1,000,000,000,000 cm2).Time period and grainBioTIME records span from 1874 to 2016. The minimal temporal grain across all datasets in BioTIME is a year.Major taxa and level of measurementBioTIME includes data from 44,440 species across the plant and animal kingdoms, ranging from plants, plankton and terrestrial invertebrates to small and large vertebrates.Software format.csv and .SQL

Ecological phytochemistry of Cerrado (Brazilian savanna) plants
The Cerrado (the Brazilian savanna) is one of the vegetation formations of great biodiversity in Brazil and it has experienced strong deforestation and fragmentation. The Cerrado must contain at least 12,000 higher plant species.We discuss the ecological relevance of phytochemical studies carried out on plants from the Cerrado, including examples of phytotoxicity, antifungal, insecticidal and antibacterial activities. The results have been classified according to activity and plant family. The most active compounds have been highlighted and other activities are discussed. A large number of complex biochemical interactions occur in this system. However, only a
small fraction of the species has been studied from the phytochemical viewpoint to identify the metabolites
responsible for these interactions
