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

Environment International, Год журнала: 2025, Номер 195, С. 109280 - 109280

Опубликована: Янв. 1, 2025

Water diversion projects effectively mitigate the uneven distribution of water resources but can also influence aquatic biodiversity and ecosystem functions. Despite their importance, impacts such on multi-domain microbial community dynamics underlying mechanisms remain poorly understood. Utilizing high-throughput sequencing, we investigated bacterial, archaeal, fungal along eastern route South-to-North project during both non-water period (NWDP) (WDP). Our findings revealed competitive exclusion effects among bacterial archaeal communities WDP, characterized by decreased species richness increased biomass, while biomass significantly declined. Distance-decay relationships suggested homogenization WDP. Robustness analyses reduced stability with primarily influencing stability, environmental factors had a greater impact communities. Stochastic processes, homogenizing dispersal drift, intensified for Notably, only functional diversity relative abundance chemoheterotrophic organic compound catabolic bacteria declined photoautotrophic bacteria. PLS-PM indicated that shaped assembly processes guilds, whereas This study enhances our understanding WDP underscores importance assessing direct resulting fluctuations.

Water masses influence the variation of microbial communities in the Yangtze River Estuary and its adjacent waters

Frontiers in Microbiology, Год журнала: 2024, Номер 15

Опубликована: Март 20, 2024

The Yangtze River estuary (YRE) are strongly influenced by the Kuroshio and terrigenous input from rivers, leading to formation of distinct water masses, however, there remains a limited understanding full extent this influence. Here variation masses bacterial communities 58 seawater samples YRE its adjacent waters were investigated. Our findings suggested that 5 in studied area: Black stream (BS), coastal East China Sea (CW), nearshore mixed (NM), middle deep layers (MM), blocks (DM). CW mass harbors highest alpha diversity across all layers, whereas NM exhibits higher surface layer but lower layers. Proteobacteria was most abundant taxa apart that, Cyanobacterium , Bacteroidota Actinobacteriota proportion CW, while BS; layer, dominant phylum BS main mass; bottom Marininimicrobia dominated DM MM masses. Network analysis suggests have obvious influence on community topological characteristics, moreover, assembly also differ greatly. Taken together, these results emphasized significant impact composition, characteristics process, which may provide theoretical foundation for predicting alterations microbial within estuarine ecosystems under

Effects of biodiversity on functional stability of freshwater wetlands: a systematic review

Frontiers in Microbiology, Год журнала: 2024, Номер 15

Опубликована: Апрель 8, 2024

Freshwater wetlands are the wetland ecosystems surrounded by freshwater, which at interface of terrestrial and freshwater ecosystems, rich in ecological composition function. Biodiversity plays a key role maintaining stability their habitat functions. Due to anthropogenic interference global change, biodiversity decreases, turn destroys function leads serious degradation wetlands. An in-depth understanding effects on its regulation is crucial for conservation. Therefore, this paper reviews environmental drivers wetlands, explores plant diversity microbial stability, reveals impacts mechanisms changes biodiversity, further proposes an outlook research. This provides important reference conservation enhancement.

Soil–Plant Carbon Pool Variations Subjected to Agricultural Drainage in Xingkai Lake Wetlands

Water, Год журнала: 2025, Номер 17(1), С. 125 - 125

Опубликована: Янв. 5, 2025

This study examines the responses of soil organic carbon (SOC) pools and their components to agricultural water drainage in paddy fields, with a focus on wetland–paddy field ecotone Xingkai Lake, transboundary lake shared by China Russia. Field investigations targeted three representative wetland vegetation types: Glyceria spiculosa (G), Phragmites australis (P), Typha orientalis (T), across durations ranging from 0 over 50 years. SOC fractions, including light fraction (LFOC), heavy (HFOC), dissolved (DOC), microbial biomass (MBC), were systematically analyzed. The results revealed that T P wetlands steadily increased duration, whereas those G exhibited fluctuating pattern. dynamics primarily driven LFOC, while MBC displayed species-specific variations. Correlation analyses structural equation modeling (SEM) demonstrated physicochemical properties, such as total nitrogen moisture content, exerted stronger influence fractions than biomass. Overall, drawdown significantly altered dynamics, distinct observed types ages. provides critical data theoretical insights for optimizing sequestration hydrological management systems.
