N2 - Soil microorganisms are sensitive to environmentdisturbances, and such alterations have consequences on microbialdiversity and functions. Our hypothesis is that alphadiversity of microbial communities and functional diversitydecrease from undisturbed to disturbed soils, with consequencesfor functional redundancy in the soil ecosystem. Totest this hypothesis, we used soil DNA shotgun metagenomicsapproach to assess the soil microbiome in a chronosequenceof land-use from a native tropical forest, followed by deforestationand cultivation of soybean croplands and pasture indifferent seasons. Agriculture and pasture soils were amongthe most diverse and presented higher functional redundancy,which is important to maintain the ecosystemfunctioning afterthe forest conversion. On the other hand, the ecosystem equilibriumin forest is maintained based on a lower alpha diversitybut higher abundance of microorganisms. Our resultsindicate that land-use change alters the structure and compositionof microbial communities; however, ecosystemfunctionality is overcome by different strategies based on theabundance and diversity of the communities.
