ABSTRACT

Simple Summary This study investigated how different land uses in the Brazilian Cerrado, a highly biodiverse region, affect soil microbial communities, particularly actinobacteria, which play vital roles in nutrient cycling and ecosystem health. We aim to understand how human activities, such as agriculture, impact soil biodiversity and microbial diversity. We found that agricultural areas had more potentially harmful bacteria and less actinobacterial diversity compared with preserved areas, which had more unknown and rare species. This study highlights the importance of protecting natural areas to maintain soil health and biodiversity. Climate change, exacerbated by human interference, intensifies biodiversity loss and soil degradation; thus, here, we show the importance of protecting natural areas to mitigate climate change effects and maintain healthy ecosystems, ultimately benefiting society through more resilient and sustainable soils.
