13. Seasonal characterization of the Net Radiation and energy balance on the Mundaú-Manguaba Estuary-Lagunar Complex (Alagoas). / Caracterização sazonal dos balanços de radiação e energia no Complexo Estuarino-Lagunar Mundaú-Manguaba (Alagoas).
The largest Brazilian area of mangroves is the second in the world and the first of th Americas. The knowledge of interaction this ecosystem with the atmosphere is important, because haven‟t a lots of meteorological papers about this subject, especially by the fact that environmental degradation modifies the ecosystem microclimate. Therefore, the study

14. Levantamento de formicídeos de fragmento de floresta atlântica no município de Eng. Paulo de Frontin, RJ (Hymenoptera, Formicidae). / Formicidae survey in a fragment of Floresta Atlântica in the county of Eng. Paulo de Frontin, RJ (Hymenoptera, Formicidae).
The east coast of Brazil, is lined with a chain of mountains where a forest known as Mata Atlântica develops. The vegetation of these mountains, because of its proximity with the coast, is under the influence of the trade winds full of humidity, from the ocean. Originally the forest extended for almost all the coast, from Rio Grande do Norte to the Rio Gran

15. POLÍTICAS PÚBLICAS E TERRITÓRIO: UMA DISCUSSÃO SOBRE OS DETERMINANTES DA EXPANSÃO DA SOJA NO SUL DO AMAZONAS / TERRITORY AND PUBLIC POLICY: A DISCUSSION ON THE DETERMINANTS OF EXPANSION OF SOYBEANS IN THE SOUTH OF THE AMAZON
The thesis aims at understanding the dynamics of soy expansion in the Amazon State, in Brazil, by identifying and characterising the politico-institutional arrangement responsible for the socio-spatial transformations that promoted the reorganisation of the use of the territory and of its resources. The issue of soy expansion is approached by relating, oppos

16. Fertilidade das camadas superficiais do solo em diferentes estágios sucessionais, no domínio da Mata Atlântica, no nordeste do estado de São Paulo / Soil fertility in superficial layers from differentes sucessions periods in Atlantic Rain forest from northeast of São Paulo state, Brazil.
In present study we evaluate the fertility variation in superficial layer of the soil in areas with primary Atlantic Forest cover, initial and late successions stages placed in Serra do Mar and Serra da Mantiqueira and pasture areas with aims to quantify the levels of degradation and recuperation through environmental chemical impacts in soil indicators. The

17. Resposta da Plataforma Continental Sudeste a ventos sazonais e sinóticos de verão: estudos numéricos / Response of the South Brazil bight to summer seasonal and synoptic winds: numerical studie
In order to study the pertubations caused on the South Brazil Bigth (SBB) caused by the passage of a cold front during Summer, a mean basic state for currents was obtained using the POM (Princeton Ocean Model) through diagnostic simulation, followed by a short round prognostic. The mean currents modeled are in certain instancies similar to the currents measu

18. Quality physical of the Luvissolo in the semi-arid of Cearà in agroforestry systems and intensive cropping / Qualidade fÃsica de um Luvissolo cultivado com sistemas agroflorestais e convencional no semi-Ãrido cearense
The introduction of agricultural systems in the natural ecosystem changes the balance of the soil, with reflections on their quality, whose impact will depend on the type of management used and the capacity to support the ground. One of the alternatives is the adoption of agroforestry systems, because these systems promote the protection of soil and are able

19. AVALIAÇÃO DA SUSTENTABILIDADE BIOFÍSICA DO SOCIOECOSSISTEMA SÃO LUIS, ATRAVÉS DO ÍNDICE PEGADA ECOLÓGICA. / EVALUATION OF SUSTAINABILITY BIOPHYSICS SÃO LUIS SOCIOECOSYSTEMIC, THROUGH THE ECOLOGICAL FOOTPRINT CONTENTS
The 7,4 billion hectares of lands ecologically productive available for human use are decreasing in an abrupt way, since last century and, more intensely, in the last decades, mainly due to the significant increase of the world human population and the consumption produced by that. From this fact, the concept of sustainability began to be part of the scienti

20. Os créditos de emissões atmosféricas reduzidas e a responsabilidade civil ambiental
Although the problem related to the weather change has been widespread only in the last decades, it is not recent the concern of the international community in the adoption of measures for the mitigation of this change in the ecosystem balance. The Kyoto Protocol, however, comes as the concrete awareness of the need of acting towards the reduction of the gre

21. âBALANÃO HÃDRICO ATUAL E SIMULAÃÃES DE CENÃRIOS CLIMÃTICOS FUTUROS PARA O MUNICÃPIO DE TAUBATÃâ
Variance affects the entire natural ecosystem such as the agriculture production, animals and, mainly, the anthropogenic activities. Agriculture shows the highest risks due to the dry seasons and the frost events and, mainly, water scarcity. The aim of this present paper is to make a water balance to the Taubatà town (1992-2005), and make a study of future

22. Experimental hydrographs of wetlands in Jacupiranguinhas river microbasins in the Baixo Ribeira do Iguape Valley, SP / Hidrogramas experimentais de área alagada da micro bacia do rio Jacupiranguinha, Baixo Ribeira do Iguape, SP
It is very important to improve our knowledge about the floodplains, which have been proved by studies, since these areas are vital to the maintenance and preservation of the quality of waters and the fluvial ecosystem. This fact, associated with the importance of the wetlands-river system, makes its investigation and preservation to be considered number one

23. Natureza e cultura: direito ao meio ambiente equilibrado e direitos culturais diante da criação de unidades de conservação de proteção integral e domínio público habitadas por populações tradicionais
The objective of this thesis lies on the analysis of the legality of administrative procedures used to create conservation units in the public domain, when traditional people inhabit the location. The research evaluated in the first place the different dimensions of fundamental rights since their historical construction, and, in detail, the specialties of th

24. Balanço de radiação, energia e fluxo de CO2 em ecossistema de manguezal na Amazônia / Radiation and energy balance and fluxes of CO2 in a Amazon mangrove ecosystem
This work use the longest series of continuous meteorological data and fluxes measurements of CO2, sensible heat and latent heat made in Amazon mangrove ecosystem. The series used in this study corresponds to the period of November, 2002 to August, 2003. The meteorological data were collected using an EDISOL system based on the hedí covariance technique. Th
