Changes on soil use influence soil dinamics, its microbiota and, therefore, biochemical cycles. Amazonian bioma is suffering dramatic changes on its soil uses over the past 30 years, as Amazonian Dark Earths (ADE) and managed soils with crops and pasture, which the burnt is currently. ADE are known to be one of the most fertile of the world and, although of many researches to discover its dinamics, there is not a comprehension of soils compartments that sustain its fertility and ecology, Greenhouse gases (GHG) are the main ruling of studies around the world and changes on the soils uses in vast territories as Amazon Forest causes concern due to the fast progress and the lack of knownleadge of its influences on the biochemical cycles of tropical forests. Another issue is the respose to the GHG increase by tropical soils. Advanced molecular studies allied to stable isotope incorporation by soil microbiota can answer the issues like: who are the producer and consumption microbiota of methane; what are their relation with soil chemical and physical components; and what their influence on methane dinamics of tropical soils. This study is innovative for being the first to evaluate the methane and consumption and emission by metatranscriptomics and Stable Isotope Probing technique to study amazonian soils from distinct vegetal coverages. The possible answer would be how the microbial ecology of soil under vegetal coverages act on methane dinamics, and also the possibility to discover novel prokaryotes and genes of biotechnological interest.
