49. 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

50. Bryophytes on rocky outcrops in the caatinga biome: a conservationist perspective
In the state of Paraíba, Brazil, there is an abundance of rocky outcrops, which are typical elements of the semi-arid landscape. Those outcrops provide refuge to species with morphological adaptations to stressful climates and to rare communities of plants, including bryophytes. Nevertheless, there have been no studies of bryophytes in such habitats in the

51. CARACTERIZACIÓN Y CUANTIFICACIÓN DE FRAGMENTOS DE BOSQUE NATIVO, EN UN SECTOR DEL SECANO INTERIOR DE LA REGIÓN DEL MAULE, CHILE
ABSTRACT In general, the Mediterranean forests have suffered high levels of fragmentation, mainly by anthropogenic action, as result of the productive activities of agriculture and livestock, human settlements and forest plantations of fast growing exotic species, leading to loss of continuity of natural forests, and thus a decrease of biodiversity. In this

52. Do edaphic aspects alter vegetation structures in the Brazilian restinga?
The vegetation of the Brazilian restinga (coastal woodland) presents a variety of species and different characteristics, encompassing fields, fruit groves and forests on quartzarenic neosols. We hypothesised that the structure of the restinga landscape along the coast of the state of Piauí is influenced by edaphic factors and presents a pattern similar to t

53. Impactos da nanotecnologia na saúde: produção de medicamentos
Several studies have described the benefits of nanoscience and nanotechnology (N&N) in different sectors such as agriculture, energy, environmental preservation, and public health. The rapid evolution of N&N can be shown through a panoramic analysis of scientific papers and patents. In the area of public health, it is estimated that the global market for nan

54. 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

55. 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

57. Estudo morfológico e hidroquímico de pequenas depressões na Nhecolândia, Pantanal, MS / Morphological and hydrochemical study of small depressions in Nhecolândia, Pantanal, MS
The southern part of the Taquari alluvial fan, called Nhecolândia, is a sub-region of the Pantanal of Mato-Grosso exhibiting a complex of round shape lakes, draining fields, forested sandy areas, small watercourses and small depressions. Former studies have shown that the sub-superficial water fluxes depend on the intensity of the flood and on the presence
