39. Use of stabilized sewage sludge in revegetation of a decapitated soil / Uso de lodo de esgoto estabilizado na revegetação de um solo decapitado
One of the consequences of urban population growth was the emergence of various environmental problems in the most of urban cities in Brazil, mainly the deterioration of water resources and land degradation caused by inadequate disposal of various types of waste generated by cities. In order to evaluate the use of sewage sludge composted with waste of grass

40. Dinâmica do uso dos recursos hídricos nas bacias do ribeirão Entre Ribeiros e do rio Preto, afluentes do rio Paracatu / Water resources use dynamics in watersheds of Ribeirão Entre Ribeiros and Rio Preto, tributaries of the Paracatu River
From times past, humanity confronts problems of environmental degradation. The environment, which always performed efficiently its function of filtration, today finds itself excessively overburdened by human activities: it suffers the risk of its resources exhausting, not being able in certain situations to recuperate itself and needing the help of man.

41. Fauna do solo e outros atributos edáficos como indicadores da qualidade ambiental em áreas com Araucaria angustifolia no Estado de São Paulo / Soil fauna and others edaphics attributes as environmental quality indicators in areas with Araucaria angustifolia in São Paulo State, Brazil
The study of biological soil quality indicators in areas with Araucaria is very important to understand ecological processes in these systems, since groups of the soil fauna are major factors in the decomposition and mineralization of organic matter, as well as modifiers of soil physical, chemical and biological properties and processes. The objective of thi

42. POTENCIAL DO Lupinus albescens Hook. &Arn. PARA RECUPERAÇÃO DE SOLOS ARENIZADOS DO BIOMA PAMPA.
As the productive processes move forward on the sandy soils of the Southwest region of Rio Grande do Sul, the arenização has been assuming relevance as factor of soil and regional ecosystem degradation. Contention measures should be established to avoid the progress of the arenização focuses and to recover the areas already damaged. Among these strategie

44. Avaliação do resíduo alcalino do refino de bauxita como condicionador de solos e do estabelecimento de dendê nos tanques de estocagem / Evaluation of red mud as soil conditioner and of the oil palm in stock tanks vegetated with leguminous trees
The production of aluminum and alumina generates a great amount of red mud, which is harmful to the environment mainly for its high pH, electric conductivity and concentration of sodium, which restrict plant growth. However, there are some indications that it may be used as a conditioner for acid sandy soils. This work tested a red mud from an alumina produc

45. Composto de lodo de esgoto como substrato para produção de mudas de arvores nativas e exoticas / Composting of sewage sludge in production of seedlings of native and exotic essences
This work has as objective to study the physical and chemical characteristics of mixtures of different ratios of organic mixture of sewage with carbonized rice straw and to evaluate the viability of the use of these materials as medium of growth for production of seedlings of native and exotic essences. The experiment was divided in three phases where divers

47. Populational and taxonomical studies of fire ants, Solenopsis invicta (Hymenoptera: Formicidae), and of the phenology of their parasitoids of the genus Psedacteon (Diptera: Phoridae) / Estudos populacionais e taxonomicos de formigas lava-pes, Solenopsis invicta (Hymenoptera: Formicidae) e da fenologia de seus parasitoides do genero Pseudacteon (Diptera: Phoridae)
This work discusses some aspects of the ecology of the fire ant species Solenopsis invicta and its phorid parasitoid flies ofthe genus Pseudacteon, and ofthe taxonomy of S. invicta and S. saevissima, both of which are native to South America. The allometry of S. invicta colonies in southeast Brazil was studied by measurement of mound (aboveground) dimensions
