2. Knowledge gaps regarding frugivorous ecological networks between birds and plants in Brazil
Abstract Vegetation stability, resilience and regeneration can be achieved by various ecological processes, the most important of which is seed dispersion. Among animal groups, birds have the largest number of frugivorous species in the Neotropics. The aim of this study was to conduct a bibliometric analysis to detect general patterns and discover knowledge

3. CHANGES IN THE SOIL STRUCTURE AND ORGANIC MATTER DYNAMICS UNDER DIFFERENT PLANT COVERS
ABSTRACT The soil properties reported in areas with different management provide useful information about the systems’ operation, state of conservation and resilience. In this way, this study evaluated physical properties and organic matter dynamics of soil under different plant covers in seven areas consisting of: five areas under ecological restoration (

4. Restoring Ecological Functions Using Agroforestry Systems in Riparian Forests
ABSTRACT Agroforestry systems and restoration models were compared with native forests by examining the restoration of ecological processes that generate stability, resilience and reliability. The stability assessment was obtained using indicators of diversity, structure and functionality. Indicators of soil protection and nutrient cycling were also used to

8. Fruits and frugivores of the Brazilian Cerrado: ecological and phylogenetic considerations
ABSTRACT Knowing the morphological and phylogenetic patterns of fruits of a plant community may elucidate plant-frugivore interactions, and analysis of dispersal syndromes is a practical approach to understanding these mutualisms. We investigated different zoochorous fruits and frugivorous animals among Cerrado formations (forest, savanna and grassland), map

9. Mechanical Properties of Woven Mat Jute/Epoxy Composites
Natural fibers combine technological, economic and ecological aspects. However, a major restriction on their successful use in long term composite applications is their high moisture absorption and poor dimensional stability. This paper is aimed at establishing a link between the mats grammage and the mechanical properties of the epoxy/jute fibers laminates.

10. Community dynamics in a species-rich patch of old-growth forest in a global changing scenario
Ecological theory predicts that, in mature ecosystems, species richness, the number of individuals and the biomass of individuals will remain in a relatively stable state of equilibrium. The aim of this study was to test that theory. In 2001 and 2010, we conducted censuses of all trees with a circumference at breast height > 10 cm in a one-hectare plot in a

11. Evaluation of the environmental sustainability of massive forestry fragments of the coastal plain and lower slopes of Bertioga (SP) / Avaliação da sustentabilidade ambiental dos fragmentos de maciços florestais da planície costeira e baixa encosta do município de Bertioga (SP)
The São Paulo coastal zone alternates extensive zones of great diversity of biotopes with others intensively degradated. These characteristics are observed in the municipality of Bertioga and its forest regions localized among Itaguaré and Guaratuba river basins. Due to their special characteristics these basins are denominated Bertioga System. The aim of

12. COMPORTAMENTO DE TALUDE DA MARGEM DO RIO SÃO FRANCISCO SUBMETIDO À TECNICA DE BIOENGENHARIA DE SOLOS. / BEHAVIOR OF THE SLOPE OF THE SÃO FRANCISCO RIVER SUBJECTED TO THE SOIL BIOENGINEERING TECHNIQUE.
The lower San Francisco river had changed their hidrossedimentological behavior by changes in river channel through the impoundment of water reservoirs for the implementation of large hydropower projects. These direct impact on the stability of river banks, demands actions to mitigate the erosion resulting from soil mass movements. Soil bioengineering, which
