We studied the bacterial communities of eight soils selected along a pedogenic gradient at the local scale in a Mediterranean calcareous mountain (Sierra de María, SE Spain). The results showed that the relative abundance of Acidobacteria, Canditate division WPS-1, and Armatimonadetes decreased whereas that of Actinobacteria, Bacteroidetes, and Proteobacteria increased from the less-developed soils (Leptosol) to more-developed soils (Luvisol). This bacterial distribution pattern was also positively correlated with soil-quality parameters such as organic C, water-stable aggregates, porosity, moisture, and acidity. In addition, at a lower taxonomic level, the abundance of Acidobacteria Gp4, Armatimonadetes_gp4, Solirubrobacter, Microvirga, Terrimonas, and Nocardioides paralleled soil development and quality. Therefore, our work indicates that the composition of bacterial populations changes with pedogenesis, which could be considered a factor influencing the communities according to the environmental and physicochemical conditions during the soil formation.enAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/AltitudeBacteriaComputational BiologyPlantsRNA, BacterialRNA, Ribosomal, 16SSoilSoil MicrobiologySpainresearch article29109410open access10.1038/s41598-017-15133-x2045-2322PMC5674076https://www.nature.com/articles/s41598-017-15133-x.pdfhttps://www.ncbi.nlm.nih.gov/pmc/articles/PMC5674076/pdf
