26. Genetic diversity of Brazilian Pantaneiro horse and relationships among horse breeds.
The objective of this work was to evaluate the genetic diversity of Brazilian Pantaneiro horse by microsatellite markers, investigate the effect of genetic bottlenecks and estimate genetic differentiation among four horse breeds. Genetic variation was estimated through allele frequencies and mean breed heterozygosity. Nei´s genetic distances among the breed

27. Cost efficiency of cryopreservation as a long-term conservation method for coffee genetic resources.
Coffee (Coffea spp.) is one of the world?s most valuable agricultural export commodities produced by small-scale farmers. Its germplasm, which holds useful traits for crop improvement, has traditionally been conserved in fi eld genebanks, which presents many challenges for conservation. New techniques of in vitro and cryopreservation have been developed to i

29. Genetic characterization of the Moxotó goat breed using RAPD markers.
The objective of this study was to verify the genetic diversity between and within seven populations of Moxotó goat (n = 264) from the States of Pernambuco, Paraíba and Rio Grande do Norte, using RAPD (Random Amplified Polymorphic DNA). Moxotó, as well as other naturalized breeds, suffers genetic losses due to the indiscriminate miscegenation with breeds

30. Características seminais de touros Curraleiros e Holandeses submetidos à insulação escrotal.
O objetivo deste trabalho foi comparar uma raça naturalizada brasileira com uma raça européia quanto à adaptação às altas temperaturas. Foram avaliados os efeitos da insulação escrotal, por 48 horas, nas características seminais de touros Curraleiros (n = 5) e Holandeses (n = 6). Uma seqüência de coletas de sêmen e avaliação andrológica dos t

31. Diversidade genética de populações de andiroba no Baixo Acre
O objetivo deste trabalho foi avaliar a diversidade genética em duas populações de Carapa guianensis Aubl. (andiroba), no Estado do Acre, e comparar os parâmetros de diversidade com os observados em outras populações da espécie (no Brasil: Flona Tapajós, PA, Porto Acre, AC; e na Costa Rica). Foram avaliados 77 indivíduos adultos com sete locos polim

32. Intellectual property in agricultural law: the legal protection of economic exploitation of traditional knowledge associated with biodiversity / A propriedade intelectual no direito agrário: a tutela jurídica da exploração econômica dos conhecimentos tradicionais associados à biodiversidade
The potential cost-effective generated by biological diversity misrepresented the sense and value of traditional knowledge associated with biodiversity, intensifying exploitation and destruction of natural resources, notably in developing countries. Protection of biodiversity is regulatory framework of the Convention on biological diversity, with three main

33. Caracterização da diversidade genética de Teca (Tectona grandis) de diferentes procedências usando marcadores microssatélites / Characterization of genetic diversity of teak (Tectona grandis) from different provenances using microsatelliate markes
Teak (Tectona grandis) is one of the main timber species in the world with high economic value, famous for its beauty, strength and durability. The species occurs naturally in India, Myanmar, Thailand, Laos and Indonesia, where diversity studies have been conducted with regard to the conservation of genetic resources. However, there is a need for studies of

34. Demografia e variação genética de Puma concolor (Linnaeus, 1771) na região nordeste do estado de São Paulo
The northeast area of São Paulo state was originally covered by cerrado and semideciduous forest, but for the last two centuries, it has experienced distinct cycles of human exploitation of its fertile soils. Despite of intensive human activities, large habitat loss and fragmentation of the native vegetation cover, pumas (Puma concolor) still inhabit remnan

35. Caracterização e diversidade genética de acessos de maracujás do cerrado com base no perfil de carotenóides / Characterization and genetic diversiy of cerrado passion fruit accessions based on carotenoids profile
The composition of carotenoids in fruits is complex and variable. Therefore, extraction methods and different analytical procedures must be applied to a correct determination of carotenoids. Fruits and vegetables are their main sources in human diet. Carotenoids are responsible by pulp color of passion fruit and many fruits, flowers and leaves. In Cerrado ar

36. Caracterização genética populacional do camarão sete-barbas Xiphopenaeus kroyeri (Heller, 1862) no litoral sudeste-sul do Brasil
Xiphopenaeus kroyeri, also known as the sea bob, is one of the most important fishery resources along the southeastern-southern coast of Brazil. However, its capture is beyond sustainable limits. Population structure analysis provides important information for the delineation of management and conservation programs. The genetic structure of the X. kroyeri po
