Taxonomic and Functional Diversity of Microbial Communities in Soils of South Brazilian Grasslands Under Different Land Uses

Soil microbial communities are key drivers of terrestrial ecosystem functioning, playing essential roles in biogeochemical cycles and in the formation and decomposition of soil organic matter. However, land-use history and agricultural intensification can significantly alter these communities. This study aimed to compare the genetic and functional diversity of soil microbial communities across three land-use types: (1) agricultural area, (2) area under passive restoration, and (3) native preserved area within Campos Gerais National Park (MMA/ICMBio/SISBIO 81846-1). Metagenomic sequencing was performed to assess the impact of land-use history on soil microbial diversity and function.
