1. Dung beetle (Coleoptera, Scarabaeidae) assemblage of a highly fragmented landscape of Atlantic forest: from small to the largest fragments of northeastern Brazilian region
Human activities in tropical forests are the main causes of forest fragmentation. According to historical factor in deforestation processes, forest remnants exhibit different sizes and shapes. The aim of the present study was to evaluate the dung beetle assemblage on fragments of different degree of sizes. Sampling was performed during rainy and dry season o

2. Selection of forest fragments to seed harvest in Itapemirim river watershed and around the Caparaó National Park / Seleção de fragmentos florestais para a colheita de sementes na bacia hidrográfica do rio Itapemirim e entorno do Parque Nacional do Caparaó
Forest fragments are the natural vegetation interrupted by anthropogenic or natural barriers, able to reduce significantly the flow of animals, pollen or seeds. The edge, the type of neighborhood, the degree of isolation and the effective size of forest fragments are the main factors that should be considered to measure changes in biological processes of a p

3. Ilhas do litoral norte do estado de São Paulo: paisagem e conservação / Ilhas do litoral norte do estado de São Paulo: paisagem e conservação
To achieve more precise models of conservation units, it´s needed to consider the importance of development of knowledge of the insular dynamics. The main goal of the study was to evaluate the relationship between the types of vegetation found in eight island of northern coast of Sao Paulo state, it´s relationship as well structural features like area, sha

4. Tipologia e fragmentação das terras úmidas do cerrado na alta bacia do Rio Araguaia, estado de Goiás / Typology and fragmentation wetland savanna int he high Araguia River basin, Goiás state
The aim of this research is to call the attention to the humid areas preservation for they are natural habitat with special dynamic and genesis and that they have been damaged by the gradual development of the use of the soil in the latest year. The upper basin of Araguaia river were chosen as an area study to follow systematically the development of Cerrado

5. Dinâmica de uso das terras nos municípios de Bonito, Jardim e Bodoquena (MS) e o estado e conservação dos recursos biológicos do Parque Nacional da Serra da Bodoquena e de sua zona de amortecimento / Spatial and temporal dynamics of land use in Bonito, Jardim and Bodoquena (MS) Municipalities, and the conservation state of the biological resources in the Serra da Bodoquena National Park buffer zone
The research approached the process of use and occupation of lands in the cities of Bonito, Bodoquena and Jardim, situated in the edge east of the National Park of the Serra da Bodoquena (NPSB), southwestern region of Mato Grosso do Sul, Brazil. Moreover, the conservation state was studied, in terms of structure and configuration of the landscape, of the con

6. Áreas agrícolas em sensores com resolução espacial de 30m estimadas a partir de dados originais e simulados MODIS e métricas de paisagem / Crop area in spatial resolution of 30m estimated with original and simulated MODIS data and landscape metrics
O agronegócio tem papel de destaque na economia brasileira. Dessa forma, a criação de metodologias para o monitoramento agrícola é fundamental. Nesta linha de raciocínio, a estimativa de área agrícola é uma atividade importante para a previsão de safras e avaliação da disponibilidade de produtos para abastecimento interno e exportações. A utili

9. Distribuição do maracanã-verdadeiro Primolius maracana (psittacidae): preferência de hábitat e fatores que influenciam na manutenção de sua populações remanescentes. / Distribution of blue-winged macaw primolius maracanã: habitat preferences and factors affecting the persistence of its remaining populations.
The blue-winged macaw is a vulnerable psittacidae, which has been suffering a rapid reduction of its populations in different parts of its occurrence. Thus, it was carried a detailed revision on the, historical and current, distribution and estatus of the species through using literature and specimens in museums data. We gathered 176 records of blue-winged m

10. Analysis of the conformational energy landscape of human snRNA with a metric based on tree representation of RNA structures
It is an outstanding problem to clarify how the RNA sequence is related to its structure and biological functions. We developed a simplified definition of a metric for tree representation of RNA secondary structures and analyzed the conformational energy landscapes of human spliceosomal snRNAs. We discuss the structural properties of the biological sequence

11. Curvature of co-links uncovers hidden thematic layers in the World Wide Web
Beyond the information stored in pages of the World Wide Web, novel types of “meta-information” are created when pages connect to each other. Such meta-information is a collective effect of independent agents writing and linking pages, hidden from the casual user. Accessing it and understanding the interrelation between connectivity and content in the Wo
