13. Aerobic fungi in the rumen fluid from dairy cattle fed different sources of forage
The objective of this study was to evaluate the aerobic microbiota of the rumen fluid from Holstein cows and heifers fed different tropical forage in the north of Minas Gerais, Brazil. A total of 30 samples of rumen fluid from cows fed with sorghum silage were collected: 32 from cows fed Brachiaria brizantha, 12 from heifers that received sorghum silage and

15. Associação de bactérias promotoras de crescimento de plantas do gênero Azospirillum com diferentes espécies de brachiaria.
ABSTRACT: The limitation of nitrogen is considered one of the most important factors to the pastures degradation. However there are evidences that pastures formed by some species of the genus Brachiaria could be benefit with the biological nitrogen fixation process (BNF), guaranteeing to these pastures higher longevity. The diazotrophic bacteria founded in a

16. Caracterização morfológica de acessos do gênero Stylosanthes no banco ativo de germoplasma da Embrapa Cerrados - coleção 1994/1995.
Resumo: A introdução de populações heterogêneas e a sua caracterização é o primeiro passo para um programa de seleção e/ou melhoramento genético de plantas. A heterogeneidade permite a seleção de indivíduos superiores que podem ser diretamente liberados como cultivares ou servir como fonte de genes em programas de melhoramento genético. A flor

17. Utilização das técnicas de ELISA e BIOLOG para estudos de diversidade intra-específica em isolados de Azospirillum amazonense associados a diferentes espécies de brachiaria.
ABSTRACT: This limitation of nitrogen is considered one of the most important factors influencing the Brazilian pastures degradation. However there are evidences that pastures formed by some species of the Brachiaria genus could be benefited by the biological fixation (BNF), guaranteeing a higher longevity to these pastures. Previous studies showed that the

18. Disseminação de bactérias patogênicas por formigas (Hymenoptera: Formicidae) em dois hospitais do nordeste do Brasil
Nosocomial infections bring a high risk to the health of hospital patients and employees. Ants are common organisms in Brazilian hospitals, where they can act as dispersers of opportunistic microorganisms in places they forage. The occurrence of multi-resistant bacteria carried by ants was analyzed in two public hospitals (HA and HB) in southeastern Bahia, B

20. Estudo da diversidade genetica e da taxa de cruzamento em Stylosanthes spp. atraves de marcores microssatelites / Genetic diversity and mating system in Stylosanthes spp. as revealed by microsatellite markers
In Brazil, most of the cattle are grown in cultivated pastures. Forage grasses belonging to the African genus Urochloa P. Beauv. have been the most commonly used, together with some American legumes. Soil degradation and high costs for reclaiming are the major problems of pastures, since nitrogen enrichment is necessary. Considering that legumes can fix atmo

21. A contribuição de zonas antropogênicas na dinâmica de uso e consumo de recursos vegetais na caatinga
Anthropogenic areas constitute an important source for plants obtainment in tropical regions, cause in them several plants are found for different purposes, such as medicinal, food and wood. The aim of this work is identify the role of the anthropogenic areas in the dynamic of use of vegetable resources, as well as assess the recognition of the found species

22. Genetic diversity in section Rhizomatosae of the genus Arachis (Fabaceae) based on microsatellite markers
The genus Arachis (Fabaceae) native to South America, contains 80 species divided into nine sections, three of which contain species of special economic importance such as the cultivated peanut (Arachis hypogaea), belonging to the section Arachis, and some perennial forage species from sections Caulorrhizae and Rhizomatosae. We used microsatellite markers to

23. Memória relacional espacial e não-espacial associada ao forrageamento em macacos-prego (Cebus spp.) mantidos em cativeiro
Primates rely on spatial information to retrieve food resources. However, they might also rely on non-spatial representations of the environment to predict the location of resources and their seasonal availability. Therefore, the study was designed to assess spatial and non-spatial relational memory in capuchin monkeys (Cebus spp.). Compared with other New W

24. Ecologia alimentar e reprodutiva de duas espécies de Tropidodryas (Serpentes, Colubridae) da Mata Atlântica / Diet and reproduction of two snakes of the genus Tropidodryas (Serpentes, Colubridae) from the Atlantic Forest
Morphology, diet, habitat use, seasonal activity and reproductive biology were analyzed and compared between Tropidodryas serra and T. striaticeps along their geographical distribution in the Atlantic Forest. The distribution of these sister species do not overlap in most of their range, T. serra have its distribution in lower altitude areaswhile T. striatic
