Viruses may facilitate the cyanobacterial blooming during summer bloom succession in Xiangxi Bay of Three Gorges Reservoir, China

Frontiers in Microbiology, 2023
The occurrence of cyanobacterial blooms in summer are frequently accompanied by the succession of phytoplankton communities in freshwater. However, little is known regarding the roles of viruses in the succession, such as in huge reservoirs.

River restoration is prone to failure unless pre-optimized within a mechanistic ecological framework | Insights from a model-based case study.

Water Research, 2020
River restoration with the use of in-stream structures has been widely implemented to maintain/improve physical habitats. However, the response of aquatic biota has often been too weak to justify the high costs of restoration projects.

Biomic river restoration: A new focus for river management

Rivers Research and Applications: an international journal devoted to river research and management, 2019
River management based solely on physical science has proven to be unsustainable and unsuccessful, evidenced by the fact that the problems this approach intended to solve (e.g., flood hazards, water scarcity, and channel instability) have not been solved

Influence of Sediment, Plants, and Microorganisms on Nitrogen Removal in Farmland Drainage Ditches

Agronomy, 2023
The removal of nitrogen from water is a consequence of the synergistic action of plant uptake, sediment sorption, and microbial decomposition. However, there is a lack of long-term experimental studies on the effects of each component in the process of ...

A model to integrate urban river thermal cooling in river restoration.

Journal of Environmental Management, 2020
River water quality and habitats are degraded by thermal pollution from urban areas caused by warm surface runoff, lack of riparian forests, and impervious channels that transfer heat and block cool subsurface flows.

Restoration challenges for urban rivers

Water Science and Technology, 2007
Urban sources account for significant quantities of important diffuse pollutants, and urban watercourses are typically badly polluted. As well as toxic metals, hydrocarbons including PAHs, and suspended matter, priority urban pollutants include faecal pathogens and nutrients.

Insights for River Restoration: The Impacts of Vegetation Canopy Length and Canopy Discontinuity on Riverbed Evolution

Water Resources Research
River restoration projects often involve vegetation planting to retain sediment and stabilize riverbanks. Laboratory experiments have explored the impact of rigid emergent vegetation canopies on bed morphology.

A Review of River Herring Science in Support of Species Conservation and Ecosystem Restoration

Marine and Coastal Fisheries, 2021
River herring — a collective name for the Alewife Alosa pseudoharengus and Blueback Herring A. aestivalis — play a crucial role in freshwater and marine ecosystems along the Eastern Seaboard of North America.

Land-Use Transformation and Its Eco-Environmental Effects of Production–Living–Ecological Space Based on the County Level in the Yellow River Basin

Land
The Yellow River Basin (YRB) serves as a critical ecological functional and economic zone in China. However, due to the rapid economic and social development, the YRB has encountered dual pressure from the anthropogenic disturbances and climate change ...
