Control of biogeochemical cycling by mobility and metabolic strategies of microbes in the sediments: an integrated model study.

abstract：:We performed high-throughput 18S rDNA V9 region sequencing analyses of microeukaryote (protist) communities at seven sites with depths ranging from 0 to 1450 m in the southern part of Lake Baikal. We show that microeukaryotic diversity differed according to water column depth and sediment depth. Chrysophytes and perki...
