Abstract
The aim of this study was to compare the structure of soil bacterial communities across a gradient of three different types of Cerrado within Sete Cidades National Park, northeast Brazil. We evaluated the preserved Cerrado sites across a gradient ranging from ‘campo graminoide’ (CG; open grassland), ‘Cerrado strictu sensu’ (CSS; savannah), and ‘Cerradao’ (CD; closed formation). Bacterial diversity, as estimated by T-RF richness and alpha and beta diversity showed different patterns across the gradient of the Cerrado. For the restriction enzyme Hha I and Msp I, the highest T-RF richness and beta diversity were found at CSS. The distribution and abundance of various fragments sizes varied between different sites. The non-metric multidimensional scaling analysis obtained with the restriction enzyme Hha I separated the sites according to bacterial community; whereas the analysis based on the restriction enzyme Msp I did not clearly separate the evaluated sites. The results show that bacterial structure does not follow the same pattern as found in the others regions with Cerrado vegetation.
