25. Influência de um fragmento florestal sobre as comunidades de macroinvertebrados de um córrego tropical degradado
Land use changes have resulted in large environmental impacts, and in agricultural landscapes sometimes only forest fragments remain. However, riparian forest remnants can influence positively stream water quality, and serve as refuge to aquatic species sensible to deforestation. We evaluated if the presence of a riparian forest remnant influences the struct

26. 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

27. Genetics and caries: prospects
Caries remains the most prevalent non-contagious infectious disease in humans. It is clear that the current approaches to decrease the prevalence of caries in human populations, including water fluoridation and school-based programs, are not enough to protect everyone. The scientific community has suggested the need for innovative work in a number of areas i

28. Photosynthesis and antioxidant activity in Jatropha curcas L. under salt stress
Biodiesel is an alternative to petroleum diesel fuel. It is a renewable, biodegradable, and nontoxic biofuel. Interest in the production of biodiesel from Jatropha curcas L. seeds has increased in recent years, but the ability of J. curcas to grow in salt-prone areas, such as the Caatinga semiarid region, has received considerably meager attention. The aim o

29. A relevância das unidades de conservação na proteção de espécies arbóreas ameaçadas de extinção da Mata Atlântica do Sudeste da Bahia / The relevance of conservation units for the protection of tree species threatened by extinction from Atlantic Forest of Southeast of Bahia
A Floresta Atlântica do sudeste da Bahia apresenta uma das maiores riquezas de espécies arbóreas por área do planeta, com uma significativa porcentagem endêmica. Essas espécies encontram-se altamente ameaçadas pelos elevados índices de desmatamento, fragmentação de habitat e corte seletivo decorrente na região. As Unidades de Conservação têm ,

31. Análise da Paisagem da Bacia Hidrográfica do Rio Tijucas, SC: Proposta de Áreas Prioritárias para um Sistema de Unidades de Conservação
The analysis of use and land cover is one of the key steps for conducting the strategic planning of conservation of a watershed. This work aims to analyze the landscape of the River Basin Tijucas for purposes of proposed priority areas for implementation of conservation, using as tool the Geographic Information System (GIS), aiming to provide support for pro

32. Uso das terras e legislação ambiental: a microbacia do Ribeirão Sapé no município de Caldas Novas (GO) / Land use and environmental legislation: the micro-basin of the municipality of Ribeirão Sapé in Caldas Novas (GO)
From the 1930s Brazil created many laws to protect the natural resources. But with the implantation of incentive programs which aim the economic growth at any cost, with modern farming practices and the expansion of agriculture and cattle raising, great losses occurred to the preservation and conservation of the natural resources. The driving question for th

33. Gestão de agregados minerais : análise e subsídios para políticas públicas / Management ggregates : comparite analysis betwen Canada and Brazil and subsidies for public policies
The biophysical and social disruption caused by aggregates mining has placed it at the center of conflict scenarios, either because of advancing urbanization on the aggregates resources or because of pressures from civil society to impose restrictions on their development. The search for solutions to this problem has required of the governments a large abili

34. Eficiência e consistência de grupos indicadores para a representação de diferentes aspectos da diversidade de vertebrados / Efficiency and consistency of indicator groups to representation of different aspects of diversity of vertebrates
Here we report the performance and consistency of indicator groups to inform conservationists about possible conservation planning scenarios in the Brazilian Cerrado and the Atlantic Forest. We explore the performance and consistency (group with equal efficiency and greater than chance in both biomes) of indicator groups for 1) determining which species are

36. Desenvolvimento de metodologia em SIG para zoneamento ecológico: estudo de caso da Bacia Ribeirão do Gama-DF.
ABSTRACT: The permanent preservation areas were created to protect the environment, decreasing processes as erosion often caused by anthropic interferences. The Brazilian Forest Law stablished criteria to the delimitation of these areas. An area zoning presents special areas where permanent preservation areas are inclued. This way, in the present paper was p
