Distinct taxonomic composition of soil bacterial community across a native gradient of Cerrado-Ecotone-Caatinga

摘要: Abstract Biodiversity underlies ecosystem functioning, and the soil microbiome plays a crucial role in these functional processes. A better understanding of relationship between microbial diversity environmental parameters would increase our ability to set conservation priorities. In recent years, ecotones have been considered an important issue ecological studies since they are ecosystems located transition two biomes where communities meet integrate. Here, we hypothesized that each area gradient Cerrado-Ecotone-Caatinga harbor distinct bacterial community mainly shaped by differential factors. To test this hypothesis, was assessed using 16S rRNA gene sequencing correlated with parameters. Our analysis revealed presented structure composition related changes such as pH, Al, temperature. Although did not find significant differences diversity, network showed decreased complexity from Cerrado Caatinga also response characteristics, number correlations proportion co-occurrence competition. Also, compositional most abundant group is adaptation properties. Overall, findings expand knowledge about areas add information can be suitable for future exploration development preservation strategies.
