Abstract

The forests of the Amazon Basin constitute the largest rainforest in the world, harboring an endemic biodiversity. However, population growth in the region hasdriven in the last decades a conversion of these areas in pastures and crops. The change in the land use leads to losses of biodiversity and disturbance processes related to carbon stock, hydrological and biogeochemical cycle. This conversion is considered the second activity that contributes most to the emission of greenhouse gases, among which is the methane. Therefore, to understand the alterations in the emission of this gas in the Amazon ecosystem, it is necessary to study microbial communities involved in the production and consumption of methane. Methane production is mediated by methanogenic archaea, acting in anaerobic decomposition of organic matter. Thisfeature is phylogenetically conserved, what makes it more responsive to human activities. Thus, this study aims to monitor methanogenic archaea communities both bycultivation or analysis based on population enrichment, using soil samples from primary forest, secondary forest and pasture in the Amazon region. It is expected to determine how changes in land use can alter the composition of these communities, their ecological and physiological characteristics. (AU)
