13. THE UNSUSTAINABILITY OF SOIL USE WITH TABACCO CROP ON STEEP SLOPES / A INSUSTENTABILIDADE DO USO DO SOLO COM FUMICULTURA EM TERRAS DECLIVOSAS
Areas susceptibility to water erosion and strong pressure of soil use, as in Southern Brazil, where there is cultivation of tobacco, are prone to degradation of the natural resources. The objective of this dissertation was to evaluate the unsustainability of the natural resources in a watershed under tobacco production, characterized by steep slopes, with in

14. Sediment morphology and distribution in a reforested riparian zone / Caracterização e distribuição espacial dos sedimentos depositados numa zona ripária reflorestada
Agricultural pratices in the state of São Paulo - Brazil, are directly responsible for the suppression of the natural vegetation cover and soil degradation. The natural vegetation was substituted by coffee, pastures, citrus and sugar-cane crops, over centuries of occupation and land use. The native forest recuperation prevents soil erosion and reduces envir

15. Análise da fragmentação de áreas de vegetação natural e semi-natural do município de Santa Cruz da Conceição, São Paulo, Brasil.
Habitat fragmentation has three major components, namely loss of the original area and reduction in size and increasing of patches. This process was helped with the development of biogeography theory, metapopulation dynamic and sink and source model. This study analyzed the landscape dynamic of the municipality of Santa Cruz, São Palo State, Brazil to base

16. Environmental Parameters Regulating Gaseous Nitrogen Losses from Two Forested Ecosystems via Nitrification and Denitrification †
Gaseous N losses from disturbed and reference forested watersheds at the Coweeta Hydrologic Laboratory in western North Carolina were studied by in situ N2O diffusion measurements and laboratory incubations throughout a 10-month period. Soil temperature, percent base saturation, and water-filled pore space accounted for 43% of the variation in in situ N2O di
