37. Estudo genético de populações caprinas locais e exóticas através de marcadores microssatélites
The aim of the present study was develop a panel of microsatellites for testing paternity in goats as an aid for conservation and improvement programs for local breeds. A total of 381 animals from 10 goat populations [six local Brazilian ecotypes/breeds (Azul, Canindé, Graúna, Marota, Moxotó and Repartida) and four exotic breeds currently used in Brazil (

40. Managing genetic diversity and society needs
Most livestock are not indigenous to Brazil. Several animal species were considered domesticated in the pre-colonial period, since the indigenous people manage them as would be typical of European livestock production. For over 500 years there have been periodic introductions resulting in the wide range of genetic diversity that for centuries supported domes

41. Breeds in danger of extintion and biodiversity
Some arguments currently used to support breed conservation are examined. The central point is that we cannot conserve all breeds because we do not have financial resources enough to keep everything (mainly in developing countries) and in many cases we do not have special reasons to conserve breeds. A breed is a human product and it should not be confused wi

42. Coalições de advocacia na formulação da política nacional de biodiversidade e florestas
Within the scope of studying the national environmental policy, this dissertation of master studies analyses the dynamic of the subsystem of the biodiversity and forest policy in the period 1992-2006. The intention is to comprehend the logic of action of the main governmental and non-governmental actors that form this policy subsystem and also the gradual ch

43. Aplicação de marcadores microssatélites na caracterização de recursos genéticos de Tabebuia roseo-alba conservados ex situ no banco de Germoplasma da floresta da USP de Ribeirão Preto / Application of microsatellite markers in the genetic resources characterization of Tabebuia roseo-alba conserved ex situ at the Germplasm Bank of the USP Forest in Ribeirão Preto State of Sao Paulo, Brazil
O interior do Estado de São Paulo, anteriormente ocupado por matas semidecíduas e cerrado, hoje está praticamente tomado por diferentes culturas ou pastagens, restando apenas algumas pequenas manchas de cerrado e de mata, apontando para uma drástica perda do rico patrimônio genético florestal. A região de Ribeirão Preto é uma das mais devastadas do

44. Estratégias de análise da diversidade em germoplasma de cajueiro (Anacardium spp. L.) / Strategies for evaluating the diversity in germplasm of the cashew (Anacardium spp. L.)
The cashew (Anacardium occidentale) is a perennial arboreal fruit tree that is actually cropped in several tropical countries around the World. The Brazilian territory is probably the original and main diversity center of this tree fruit, as well as for most species of the genus Anacardium. On the other hand, studies concerning to the evaluation and characte

45. A importância de remanescentes de Mata Atlântica na ocorrência dos Muriquis (Brachyteles hypoxanthus E. Geoffroy) no Estado do Espírito Santo / The importance of Atlantic Rainforest reminders of the Muriquis (Brachyteles hypoxanthus E. Geoffroy) occurrence in Espirito Santo State, Brazil
Espirito Santo (Brazil) highland area presents forest remainders of exuberant beauty, with fauna and flora of high relevance to the conservation. In these forests, the threatened Brachyteles hypoxanthus (herbivore and arboricol primate, endemic of highlands mountain ranges of the Atlantic Rain Forest in Minas Gerais, Espirito Santo and Bahia States) can stil

46. Genetic structure of the sea-bob shrimp (Xiphopenaeus kroyeri Heller, 1862; Decapoda, Penaeidae) along the Brazilian southeastern coast
The sea-bob shrimp, Xiphopenaeus kroyeri, is one of the most important economic marine resources along the entire Brazilian coast. Nevertheless, despite its economic importance, no studies have examined the population genetics of this species. In this paper, we used ten allozyme loci to study the pattern of genetic structuring in X. kroyeri along the southea

47. GerminaÃÃo de sementes de soja armezenadas em bancos de germoplasma / Soybean seeds germination stored in genebanks.
The conservation of plant genetic resources in genebanks, mainly as seeds, has the purpose of preserving the genetic materials that could be useful to mankind, by using techniques that give as higher longevity as possible to those stored seeds. The genebanks are the main places to let the genetical resources needed available to get new cultivars and/or to br

48. Uso e diversidade genética em populações naturais de biriba (Eschweilera ovata [Cambess.] Miers): subsídios ao manejo e conservação da espécie. / Use and diversity genetic in natual populations of biriba (eschweilera ovata [cambess.] miers): subsidies to management and conservation of specie.
The exploitation of non-timber resources from tropical forest has been an alternative income to local human communities. Among the tree species which are exploited in the Atlantic forest, the biriba Eschweilera ovata (Cambess.) Miers has been used to manufacture the arc of berimbau. The genetic conservation and the sustainable management of E.
