13. Biological control of Aphis gossypii Glover (Hemiptera: Aphididae) in protected crop of cucumber using Marigold (Tagetes erecta L.) / Controle BiolÃgico do pulgÃo Aphis gossypii Glover (Hemiptera: Aphidae) em cultivo protegido de pepino com cravo-de-defunto (Tageres erecta L.)
Protected crop is a used practice in Brazil and abroad. Some characteristics like stable climate, high temperature and availability of food, favor the occurrence of pests on these systems, among them the Aphis gossypii. These insects are usually controlled chemically, which when applied in closed systems have little dispersion, thereby increasing its concent

14. Small mammals communities in the forest fragments connected by vegetation corridors in the south of Minas Gerais / Comunidades de pequenos mamÃferos em fragmentos florestais conectados por corredores de vegetaÃÃo no sul de Minas Gerais
The forest fragmentation is one of the main threats for the biodiversity. For the fauna, the consequences associated to the forest fragmentation are the original habitat loss, reduction of the fragment size and isolation, which create a number of negative effects over the wild populations, affecting the species richness, the abundance and the animal species

15. Development of a Multimetric Index of Ecological Integrity for streams in the urban area of Campo Grande (Mato Grosso do Sul), based on benthic macroinvertebrates / Desenvolvimento de um Índice Multimétrico de Integridade Ecológica para córregos na área urbana de Campo Grande (Mato Grosso do Sul), baseado em macroinvertebrados bentônicos
Water pollution is a growing problem, especially in the water courses that flow through urban centres, receiving residential, commercial and even industrial effluents. The small amount of control that exists is often done by means of physical, chemical and bacteriological analyses. The lack of a biological alternative may be due to the paucity of research in

16. Small mammals of the Atlantic Forest of the Atlantic Plateau of São Paulo: an evaluation of the threat of extinction and the response to alterations in context and remnant size / Pequenos mamíferos da Mata Atlântica do Planalto Atlântico Paulista: uma avaliação da ameaça de extinção e da resposta a alterações no contexto e tamanho dos remanescentes
A long-term standardized survey of the Atlantic Forest small mammals was conducted using pitfall traps in 68 sites distributed in six 10.000-ha landscapes (three in continuous forest and three in fragmented landscapes) located in three regions in the Atlantic Plateau of São Paulo. The fragmented landscapes harbored different amounts of remnants, 50%, 30% an

17. ANÁLISE ESPACIAL DOS FRAGMENTOS FLORESTAIS NA ÁREA DO PARQUE NACIONAL DOS CAMPOS GERAIS, PARANÁ
The fragmentation of habitats figures into the most serious threats to the conservation of ecosystems nowadays. As a direct result of the human action, the fragmentation of the natural environment produces different environments that modify the dynamic of ecological relations among fauna, flora and the abiotic system. The rupture of a landscape unit generate

18. Ecologia de Florestas Atlânticas com ocorrência do muriqui (Brachyteles spp.): diversidade, sucessão secundária e estrutura nutricional / Atlantic Forests ecology holding muriqui (Brachyteles spp.): diversity, secondary succession and nutritional structure
This study has three chapters which mainly aimed the understanding on the role of forests variables affecting distribution, abundance and range ecology of primates belonging to Brachyteles genera. The first chapter specifically aimed on characterization and comparisons of tree species diversity and secondary succession among three forests holding Brachyteles

19. Extinction of canid populations by inbreeding depression under stochastic environments in Southwestern Goiás State: a simulation study
A frequently addressed question in conservation biology is what is the chance of survival for a population for a given number of years under certain conditions of habitat loss and human activities. This can be estimated through an integrated analysis of genetic, demographic and landscape processes, which allows the prediction of more realistic and precise mo

20. "Diversidade de anuros e lagartos em fisionomias de Cerrado na região de Itirapina, Sudeste do Brasil" / Diversity of anurans and lizards in Cerrado physiogmonies in the region of Itirapina, southeastern Brazil
Several theories have been proposed to explain areas of high diversity worldwide. The Cerrado is the most diverse tropical savanna, with a diverse,endemic herpetofauna distributed in different types of vegetation. The cerrado vegetational types vary from forest to grasslands and represent distinct habitats for the herpetofauna. In the region of Itirapina, so

21. Ecologia das interações entre formigas e a mirmecófita Tococa guianensis no Cerrado brasileiro
Tococa guianensis (Melastomataceae) is one of the few existing myrmecophytic species in the Brazilian Cerrado, and although it is commonly found in the gallery forests (and eventually in grassland vegetation) of this biome little is known about the interaction between ants and T. guianensis. For this I analyzed three populations of T. guianensis in central B

22. Racismo e Movimentos Instituintes na Escola
Despite the eloquence of the speeches proclaimed by the society as well as in schools, confirming the democracy, the fight against the disparities and the respect for the differences, we are confronted everyday with a reality of reproduction of the racism. Testifying this reality, we understand that the racism is sustained by multiple dimensions. Among many,

23. Ecologia da comunidade aquática de um riacho de 1 ordem da Mata Atlântica: relações entre variáveis estruturais e bióticas em uma reserva de biosfera tropical.
This study was developed in arroio Carvão, a 1 order stream at the Maquiné watershed, in the southern part of Atlantic Rain Forest, Brazil. The headwaters are within the Serra Geral Biological Reserve, a conservation unit that is a regional biodiversity core area of the Atlantic Forest Biosphere Reserve. The research was developed to identify the role of p

24. Padrões de dispersão e utilização de recursos em uma população de Heliconius erato phyllis (Lepidoptera, Nymphalidae)
Data were obtaineid about home range, diespersion of individuals, dispersion of contacts with host plants and flowers, and use of communal roosts in a populations of Heliconius erato phyllis (L.) in the Horto da Ferrovia Paulista S/A. at Sumaré, State of São Paulo, Brazil, from June, 1979, to April, 1980. These data, with the exception fo thouse about comm
