Phytoplankton community assembly in an inter-basin water diversion project: Dominance of temporal dynamics over spatial dynamics.

Large-scale water diversion projects play a critical role in the redistribution of essential water resources. Despite their crucial role in maintaining water quality and ecosystem stability in water diversion projects, a deeper understanding of the transport mechanism of phytoplankton in water diversion has yet to be thoroughly explored. A systematic investigation was conducted to better understand the ecological processes related to phytoplankton in the mammoth Middle Route of the South-North Water Diversion Project.

Development of LaCeOCO solid solution for low-concentration phosphate removal and recovery: manipulating Ce ratio and valence to boost phosphate capture.

The removal and recovery of low-concentration phosphates from water have become crucial due to the dual challenges of eutrophication and the phosphorus crisis. Herein, we engineered a highly efficient and recyclable phosphate trapping agent of LaCeOCO solid solution. The incorporation of Ce enhances the surface area and surface potential of LaCeOCO, providing abundant adsorption sites for phosphate.

Untangling the impacts of bacterial community on carbon dioxide and nitrous oxide across a drinking water reservoir.

Reservoirs represent a critical component of greenhouse gas (GHG) emissions, yet the intricacies of how biotic and abiotic factors influence GHG dynamics within reservoirs remain largely unexplored. Herein, we investigated the spatiotemporal patterns of CO and NO emissions and the underlying factors in the Danjiangkou Reservoir, Asia's largest artificial freshwater reservoir. We found that this reservoir was a significant source of GHGs to the atmosphere, with peak CO emissions observed in autumn (1544.

Differential impacts of water diversion and environmental factors on bacterial, archaeal, and fungal communities in the eastern route of the South-to-North water diversion project.

Water diversion projects effectively mitigate the uneven distribution of water resources but can also influence aquatic biodiversity and ecosystem functions. Despite their importance, the impacts of such projects on multi-domain microbial community dynamics and the underlying mechanisms remain poorly understood. Utilizing high-throughput sequencing, we investigated bacterial, archaeal, and fungal community dynamics along the eastern route of the South-to-North water diversion project during both non-water diversion period (NWDP) and water diversion period (WDP).

[Effects of Heavy Metal Pollution on the Structure of Microbial Communities in Different Habitats].

Heavy metal pollution seriously threatens the diversity and composition of microbial communities in various ecosystems. However, little is known about the effects of heavy metal pollution on the structure of microbial communities in the three habitats of "surface water-sediment-groundwater." Here, with help of 16S rRNA high-throughput sequencing technology, the diversity and composition of microbial communities, as well as the underlying controlling factors, were investigated and compared among the surface water, sediment, and groundwater of the Tanghe sewage reservoir.
