Biogeochemical consequences of rapid microbial turnover and seasonal succession in soil.

abstract：:Factors controlling the spatial distribution of bacterial diversity have been intensely studied, whereas less is known about temporal changes. To address this, we tested whether the mechanisms that underlie bacterial temporal beta-diversity vary across different scales in three marine microbial communities. While seas...
