Water-sediment exchanges control microbial processes associated with leaf litter degradation in the hyporheic zone: a microcosm study.

abstract：:Marine Crenarchaeota represent a widespread and abundant microbial group in marine ecosystems. Here, we investigated the abundance, diversity, and distribution of planktonic Crenarchaeota in the epi-, meso-, and bathypelagic zones at three stations in the South China Sea (SCS) by analysis of crenarchaeal 16S rRNA gene...
