Summary: This paper explores the efficiency of identifying impacts and main indicators in the environmental impact assessment (EIA) process and post-environmental impact assessment (PEIA) process for dam projects and proposes the optimization and application of a decision-support prototype (DSP) toolkit for Chinese dam projects. It also highlights the importance of focusing on relevant environmental concerns and knowledge gaps during the early stages of negotiation to facilitate subsequent studies and evaluative processes.

Summary: This study investigated the alternative microbiota states and their responses to environmental conditions in the Yangtze River. It was found that flow discharge was the main factor that clustered benthic microbiota into two types, and reducing flow discharge could shift benthic microbiotas to a state where benthic cyanobacteria would become the dominant species. The study also showed that the bistable region is susceptible to the microbiota state of its upstream and deserves more scientific attention to prevent the unfavorable state from spreading downstream.

Summary: The impoundment of cascade mega-reservoirs in the upper Yangtze River has had profound and accumulative impacts on the lower reaches, leading to a significant decrease in sediment load and a change in the runoff-sediment relationship. This study analyzed data from 1990 to 2021 to examine the changes in sediment suspension in the Jingjiang reach, approximately 100 km below the Three Gorges Dam. The impacts of cascade mega-reservoirs were evaluated using three parameters: inflow water discharge, sediment concentration released to the Three Gorges Reservoir, and operating water levels in front of the dam. The relative importance of these parameters in determining wash-load concentrations was assessed using a random forest model.

Summary: Cascade dams have significant impacts on river ecosystems by altering river connectivity, hydrological processes, and hydraulic properties. This study focused on benthic macroinvertebrate assemblages in the lower Jinshajiang River, revealing that dam construction led to considerable changes in macroinvertebrate communities, reducing diversity and abundance of certain taxa while increasing others in the reservoir reach of the mainstream. Maintaining natural river sections between cascade reservoirs is crucial for preserving the biodiversity of benthic macroinvertebrates.

Summary: The study of nonstationary flood behavior in the upper Yangtze River reveals decreasing trends in annual maximum flood peak flow and flood volume at most control stations, along with earlier flood peak occurrence times and changes in flood process uniformity. The change points of most evaluation indicators occurred in the 1970s-1990s, with contributions from climatic control and the Three Gorges Dam playing significant roles in the variation of annual flood peaks.

Summary: Cascade dam construction has significant impacts on the habitat and fish population in the Lancang River basin, especially for the endemic fish species Schizothorax prenanti and Schizothorax davidi. This study utilized an ecohydraulic modeling framework to examine habitat quality and fish population under different dam scenarios. The results showed that dam construction would fragment the spawning site habitat in the main stream while improving spawning site habitats in tributaries, leading to changes in fish population abundance and density. The study highlights the importance of considering species and life stages in dam construction impacts and provides a useful tool for decision-makers involved in river ecosystem conservation.

Summary: This study analyzes the eco-environmental impacts of dams in the Yangtze River Basin in China, finding that the negative environmental effects of existing dams have significantly increased, affecting downstream areas and reservoir regions. The construction of dams has reduced the complexity of runoff and sediment loads in the short term, reflecting a filtering effect on the temporal and spatial patterns.

Summary: The boom in dam construction and continuous river-lake exchange has had a profound impact on the transmission and transformation of riverine dissolved inorganic carbon (DIC). An in-depth understanding of the change mechanisms of DIC concentrations and sources driven by dam operation and lake recharge is crucial for regulating greenhouse gas emissions and evaluating the impact of DIC on the global carbon cycle.

Summary: The Tibetan Schizothoracinae fish Gymnocypris przewalskii, known for its ability to adapt to the extreme plateau environment, has been studied for its transcriptome features using long-read sequencing technology. A total of 159,053 full-length transcripts were captured, with a significant amount of them well-annotated and containing complete open reading frames. The FL transcriptome provides a solid foundation for future research on G. przewalskii.

Summary: The study showed that monitoring effectiveness was higher on summer or autumn rainy days, and monitoring of bacterial biodiversity information was more efficient. On summer rainy days, 43-76% of species information from riparian sites could be detected in adjacent riverine water eDNA samples, and 92-99% of species information from riverine sites could be detected in a 1-km downstream eDNA sample.

Summary: In aquatic animals, gut microbial communities are influenced by host development and living environments. The colonization and dynamics of these communities are affected by the environment. A study on wild fish populations found that the majority of gut microbes are shared with the water environmental microbial community, and most of them are transient.

Summary: Riverbed substrate is crucial for the growth, reproduction, and predation of fish in a river ecosystem. This study investigated the riverbed substrate requirements for the natural reproduction of Gymnocypris przewalskii through artificial simulation and spawning ground substrate transformation experiments. The results showed that pebble substrate significantly promoted the reproduction of Gymnocypris przewalskii, providing guidance for wild population recovery and restoration of natural spawning grounds.

Summary: The Yangtze River is home to diverse fish species and serves as an important inland fishery resource in China. However, its ecosystem is facing an uncertain future due to human impacts. Fish stocks in the river are particularly vulnerable. While a 10-year ban on commercial fishing has been implemented, it alone cannot guarantee full recovery. Therefore, multidisciplinary strategies at the basin scale are necessary for effective conservation.

Summary: Six freshwater fish species from the middle section of the Yangtze River were analyzed for their length-weight relationships (LWRs). The LWR parameters of all six species were statistically significant. New maximum TL measures were recorded for four of the species, and the LWRs of three species were published for the first time, contributing to fishery research, management, and conservation of the Yangtze River ecosystem.

Summary: The COVID-19 lockdowns have had significant impacts on the aquatic ecosystems of the Yangtze River. The reduction in industrial and domestic effluent discharge during the lockdowns led to a decrease in organic and nutrient pollution in the river. This decrease in nutrient supply inhibited the growth of algae and resulted in a decrease in phytoplankton abundance. This, in turn, affected the density of zooplankton and led to lower primary productivity in the river. The decrease in fishing intensity also had an impact, resulting in an increase in the number of migratory fish and a more complex and diverse fish community structure.

Summary: The gut microbiota of aquatic animals is influenced by the environmental microbiota and plays a significant role in their health. To assess and predict the health of aquatic animals, a general microbiota health index (microHI) based on microbial phenotypes was proposed and tested. The results showed positive correlations and potential for using the microHI to evaluate the health status of aquatic animals.

Summary: The Yangtze sturgeon is an important aquatic animal at the national level, but its natural population in the wild has almost disappeared. Through a study of hatchery reared individuals released into the wild, it was found that adult Yangtze sturgeons prefer an anadromous migration and settled life in the wild. The study provided important insights for the reconstruction and restoration of wild populations and future stock enhancement.
