Keywords: Forest soil; Metagenomics; Pyrosequencing; Soil physicochemical characteristics Abstract Deforestation or clear-cut logging affects forest ecosystems, including soil microbial communities. The purpose of this study was to investigate the effects of clear-cut logging on the soil bacterial community in a temperate deciduous broad-leaved forest on Mt. Sambong, South Korea. We investigated the physicochemical characteristics and bacterial diversity of the soil in clear-cut logging and control sites. The available phosphorus (AP) level in soil was significantly lower in the clear-cut sites than in the control however, the other physicochemical properties of soil were similar at the two sites. By examining the bacterial 16S rRNA gene using next-generation sequencing, we found that the number of bacterial taxa at the species and phylum level were similar at the control and clear-cut sites. Consistent with the high resilience of bacterial communities and absence of change in the soil physicochemical properties--with the exception of AP--we found similar levels of bacterial diversity at the two sites. Although most taxa showed similar composition ratios at the control and the clear-cut sites, some taxa such as Deltaproteobacteria, Ktedonobacteriales, Myxocccales, Polyangiaceae, Pedosphaera_f, and Solibacter showed differences after clear-cut logging. We conclude that AP was significantly associated with those bacterial taxa that showed differences in their composition ratios following clear-cut logging.
