25. 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

26. Efeitos da espacialização da cobertura florestal e da profundidade dos solos na produção de água de uma bacia hidrográfica / Effects of the spatial distribution of forest cover and the soil depth in water yield of a watershed
Several works related to the theme of water production are being made, having in common the association of forest cover with runoff in watersheds. However, no studies were found where the places where this land cover has optimum effect, because it is dependent on climatic and physiographic conditions of each watershed. The objective of this study is to evalu

27. Avaliação dos remanescentes florestais do Município de Brança Paulista - SP e áreas adjacentes: base para o estabeleciemento de corredores ecológicos. / Evaluation of the remaining forest in the city of White Paulista - SP and surrounding areas: estabeleciemento basis for ecological corridors.
Fragmentation and habitat loss are currently the major factors that threaten biodiversity and are major causes of extinction. One strategy for biodiversity conservation is the creation of ecological corridors which are areas of connectivity between isolated fragments. The municipality of Bragança Paulista is located in the Atlantic Forest Domain, which expa

28. Resposta do clima amazônico ao desmatamento progressivo da Amazônia e do Cerrado / Response of the Amazonian climate to progressive deforestation of the Amazon and Cerrado
There is a clear shift happening in the physical environment of the Amazon forest, where human intervention has intensified dramatically during the last half of the twentieth century. Recent studies suggest that changes in regional climate caused by local deforestation have the potential to cause parts of the Amazon to cross an ecological tipping point: a cr

29. Qualitative and anatomical characteristics of tree-shrub legumes in the Forest Zone in Pernambuco state, Brazil
The objective of this study was to characterize the nutritional value of forage legumes Mimosa caesalpiniifolia (Benth.), Bauhinia cheilantha (Bong.) and Leucaena leucocephala (Lan.) and evaluate the anatomy of plants incubated and not incubated in the rumen. The experiment was conducted from September 2007 to November 2008. The experimental plot consisted o

30. Diversity and composition of tiger moths (Lepidoptera: Arctiidae) in an area of Atlantic Forest in southern Brazil: is the fauna more diverse in the grassland or in the forest?
The Atlantic Forest is considered a biodiversity hotspot for conservation, because its fauna and flora are highly endemic and suffer from loss of natural habitats. This study assessed the composition and diversity of tiger moths (Lepidoptera: Arctiidae) in two floristic formations of the southern Atlantic Forest (grassland and Araucaria forest) and in a tran

31. Análise integrada do uso e aptidão agrícola dos solos na Amazônia Legal visando o desenvolvimento sustentável
Encroachment of the agricultural frontier over the Brazilian Amazon (Amazônia Legal) forest and savanna (cerrado) areas generates an array of negative environmental impacts, such as deforestation and fires. The conflict between the pressing agricultural front, mainly represented by cattle and soya productions, and the preservation of such forest and cerrado

32. Modelagem do escoamento superficial e perda de solo na bacia do ribeirão São Bartolomeu, Zona da Mata de Minas Gerais, utilizando o simulador SWAT / Modeling of runoff and soil loss in the São Bartolomeu stream watershed, Forest Zone of Minas Gerais, using the SWAT simulator
A avaliação quantitativa da perda de solo por erosão, da perda de água e das cargas de sedimentos que atingem os corpos dágua é fundamental para o planejamento ambiental em escala de uma bacia hidrográfica, contribuindo para o processo de tomada de decisão relacionado às melhores opções de manejo do solo e à manutenção da qualidade dos recursos

33. Water use and grain yield response of rainfed soybean to tillage-mulch practices in southeastern Nigeria
Despite the agronomic, economic and food values of soybean (Glycine max L. Merrill), there is still dearth of information on the tillage need and the implications of surface mulch for the crop in the eastern part of the forest-savanna transition zone of Nigeria. This study was therefore carried out on a sandy loam Ultisol at Nsukka with a sub-humid climate,

34. Dinâmica de crescimento de Cedrela odorata L. (Meliaceae) na Floresta Atlântica do Estado do Rio de Janeiro: fenologia, atividade cambial e dendrocronologia / Growth dynamics of Cedrela Odorata L. (Meliaceae) on the Atlantic Rain Forest of the State of Rio de Janeiro: phenology, cambial activity and dendrochronology
Along the 20th century, a few dendrochronological studies were developed with tropical species, according to the belief that variations of the climatic conditions on those regions werent regular and strong enough to induce an annual rate of radial growth. The researches on this topic in the last decades showed that the formation of annual growth rings in the
