Temperate forest soil Metagenome

The overall aims of this study were (1) to explore soil bacterial communities in four typical temperate forest types from Changbai Mountain (Broad-leaved Korean pine mixed forest, Secondary poplar-birch forest, Spruce-fir forest, and Larch forest) with newly developed bar-coded 454 pyrosequencing method; (2) to elucidate the biotic and abiotic factors controlling the abundance, diversity and composition of soil bacterial communities; (3) to test if the differentiation of soil bacterial communities in these temperate forests support the copiotroph/oligotroph functional classification model and the non-random co-occurrence patterns. This study will provide the first glimpse at the potential role of above-ground vegetation in allowing niche differentiation of soil bacterial communities in natural temperate forests situated in Changbai Mountain, and tries to reveal the intrinsic mechanism of such differentiation.
