25. Multivariate Analysis and Machine Learning in Properties of Ultisols (Argissolos) of Brazilian Amazon
ABSTRACT: Ultisols are the most common soil order in the Brazilian Amazon. The Legal Amazon (LA) has an area of 5 × 106 km2, with few accessible areas, which restricts studies of soils at a detailed level. The pedological properties can be estimated more efficiently using statistical procedures and machine learning techniques, tools which are capable of rec

26. Água-régia como extrator alternativo para o diagnóstico ambiental de áreas impactadas por resíduos industriais: estudo de caso Centres (Queimados, RJ)
RESUMO Áreas contaminadas por metais podem configurar sério risco à saúde pública e ao meio ambiente. Na década de 1980 foi instalado um pátio de estocagem provisória de resíduos industriais perigosos (CENTRES), no município de Queimados, Rio de Janeiro, o que causou um grande impacto ambiental ao solo da região. A legislação brasileira para o d

28. Antiherbivory defense mechanisms along an environmental gradient in restinga
ABSTRACT Plant-herbivore interactions have directed the evolution of defense mechanisms in plants, which can vary intraspecifically according to environmental quality. This study evaluated variation in the production of antiherbivory defenses in plant species distributed along an environmental gradient of restinga. The study was performed in Parque Estadual

29. Do fruit morphology and scarification affect germination and predation rates of Babassu seeds?
ABSTRACT Seed predation is a natural phenomenon that can occur either before or after dispersal and can significantly reduce the economic value and reproductive potential of plants. The babassu palm (Attalea vitrivir, Arecaceae) is important to rural communities that extract oil from its fruits for a wide variety of uses. We evaluated the predation and germi

30. Orchidaceae in an Atlantic Forest area: floristics and similarity to other Dense Ombrophilous Forest fragments
The Brazilian Atlantic Forest is considered a global hotspot for biodiversity although it is currently threatened and highly fragmented. Orchidaceae in this phytogeographical domain is represented by 148 genera, of which 142 are endemic; Rio de Janeiro State contains approximately one third of all Brazilian orchid species. The Wildlife Protection Zone of the

31. Trends in Mean Annual Streamflows in Serra da Mantiqueira Environmental Protection Area
The aim of this study was to detect trends in the mean annual streamflow in watersheds of Serra da Mantiqueira Environmental Protection Area, an important Brazilian conservation area located between Minas Gerais, São Paulo and Rio de Janeiro States. Historical series of four selected streamgage stations were analyzed for the periods of 1980-1998 and 1980-20

33. Health risk assessment of heavy metals in vegetables grown around battery production area
Battery production is one of the main sources of heavy metals that present great harm to human health even in low concentrations. Chromium (Cr), Cadmium (Cd) and Lead (Pb) were measured in edible portions of vegetables and soils around a battery production area in China, and the potential health risk of heavy metal contamination to the local population via v

34. Variation of essential oil composition of Tapirira guianensis Aubl. (Anacardiaceae) from two sandbank forests, north of Brazil
Tapirira guianensis (Anacardiaceae) is used in traditional medicine and is important for the recovery of degraded areas and riparian forests because the T. guianensis fruits are highly consumed by wildlife. Volatile components from dried leaves and branches of five individual plants of T. guianensis were collected in two sandbank forests of the State of Par�
