The environment has a strong control effect on plankto bacterial community.

Plankto bacteria, as the most abundant microbiome in freshwater lakes, are involved in almost all material circulation and energy flow in lakes.
Wuhan East Lake is one of the representative lakes in the field of lake ecology research, but the long-term scale replacement law and ecological driving mechanism of plankton bacterial community in its ecosystem are very inadequate.
Since 2007, Yu Yu, a researcher at the Institute of Aquatic Biology of the Chinese Academy of Sciences, and his team have focused on the space-time pattern and ecological drive process of the floating bacterial community in Wuhan East Lake, and have carried out nearly 10 years of systematic research on plankton bacteria in the five major lake areas of East Lake through high-pass amplification son sequencing and systematic evolution analysis.
results show that the seasonal evolution of the floating bacterial group in East Lake on a long-term scale is mainly subject to the decisive ecological process, that is, the strong uniform selection is accompanied by certain diffusion restrictions.
suggests that ecologically similar and closely related species can replace each other when groups take over, indicating significant functional redundancy, or at least ecological redundancy, within the season.
However, environmental choices (e.g. temperature, nutrition, etc.) and biological interactions (e.g. predation, symbsonation, etc.) make a significant difference between different seasons of plankto bacteria, mainly because the environmental conditions of different seasons provide different ecological levels;
this change also suggests that the environment has a strong control over plankto bacterial community, which may lead to the prediction of ecosystem trends through ecological process models.
the study was conducted primarily by the Aquatic Research and Research Team, the Yan Qingyun Team at Sun Yat-sen University, and the University of Oklahoma Week Focus team, and the results were published online in Molenecular Ecology.
, Yu Yu and his team have conducted a more systematic study of the molecular ecology of plankton in Wuhan's East Lake (Microbial Ecology; FEMS Microbiology Ecology).
