Avaliou-se a produção por animal e por área, em pastagens consorciadas de Brachiaria decumbens e Stylosanthes guianensis cv. Mineirão e de B.brizantha cv. Marandu e S. guianensi cv. Mineirão, sob três taxas de lotação, 0,8, 1,2 e 1,6 UA/ha, durante as épocas seca e das águas, no Cerrado. Foram utilizados novilhos Nelore, desmamados, durante o terceiro ciclo de pastejo. A produção por animal foi afetada pela taxa de lotação , de modo linear decrecente, com valores estimados de 435, 371 e 308 g/animal.dia, para as respectivas taxas. As pastagens com B. decumbens proporcionaram maiores ganhos por animal do que as pastagens com B. brizantha e consequentemente, maior ganho em peso por área 464 e 352kg/ha, respectivamente. |

Abstract: Mangrove ecosystems are tropical environments that are characterized by the interaction between the land and the sea. As such, this ecosystem is vulnerable to oil spills. Here, we show a culture-independent survey of fungal communities that are found in the sediments of the following two mangroves that are located on the coast of Sao Paulo State (Brazil): (1) an oil-spill-affected mangrove and (2) a nearby unaffected mangrove. Samples were collected fromeach mangrove forest at three distinct locations (transect from sea to land), and the samples were analyzed by quantitative PCR and internal transcribed spacer (ITS)-based PCRDGGE analysis. The abundance of fungi was found to be higher in the oil-affected mangrove. Visual observation and correspondence analysis (CA) of the ITS-based PCR-DGGE profiles revealed differences in the fungal communities between the sampled areas. Remarkably, the oil-spilled area was quite distinct from the unaffected sampling areas. On the basis of the ITS sequences, fungi that are associated with the Basidiomycota and Ascomycota taxa were most common and belonged primarily to the genera Epicoccum, Nigrospora, and Cladosporium. Moreover, the Nigrospora fungal species were shown to be sensitive to oil, whereas a group that was described as ?uncultured Basidiomycota? was found more frequently in oil-contaminated areas. Our results showed an increase in fungal abundance in the oil-polluted mangrove regions, and these data indicated potential fungal candidates for remediation of the oilaffected mangroves.
