Previous research has focused on the impacts of ammonia-oxidizing microbes on soil nitrification under agricultural management, but the influence of the interaction between microfauna, particularly nematodes, and ammonia-oxidizing microbes on soil nitrification remains unclear. In this study, we selected four rates of N applied to lime concretion black soil and fluvo-aquic soil and tested the effect of the interplay of nematodes with ammonia-oxidizing archaea (AOA) and bacteria (AOB) on the potential nitrification rate (PNR). The results demonstrated that the application of N to the fluvo-aquic soil led to an increase in the PNR, as well as a significant enhancement in the abundance of copies of the AOA and AOB <em>amoA</em> genes. However, no consistent outcomes were observed in the lime concretion black soil. The application of N increased the relative abundance of bacterivorous nematodes, particularly <em>Chiloplacus</em>, in the fluvo-aquic soil, but it decreased their relative abundance in the lime concretion black soil. A co-occurrence network analysis indicated that the AOB nodes accounted for a higher proportion in the network and had more potential associations with bacterivorous nematodes in the fluvo-aquic soil. The partial least-squares path model suggests that bacterivorous nematodes positively regulated the AOB and further influenced the PNR in the fluvo-aquic soil. These results provide novel insights into our understanding of the processes of soil nitrification, as well as the interactions between soil microorganisms and nematodes.</div></div>","PeriodicalId":356,"journal":{"name":"Journal of Environmental Management","volume":"386 ","pages":"Article 125706"},"PeriodicalIF":8.0,"publicationDate":"2025-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144071817","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hydrological conditions can affect multiple aspects of the lake environment, thereby interfering with DOM cycling. This study investigates the long-term trends and drivers of DOM accumulation in Lake Erhai, a subtropical plateau lake in southwestern China, focusing on the role of hydrological processes in driving its accumulation and persistence. By analyzing data from 1992 to 2023—including bulk chemical analysis, 3D-EEM fluorescence spectroscopy, degradation experiments and bayesian structural equation modeling (BSEM), it is concluded that a 174 % increase in water residence time (WRT), from 2.8 years to 7.8 years, driven by reduced inflow and outflow volumes, has promoted the accumulation of refractory DOM (RDOM), raising chemical oxygen demand (COD_Mn) and presenting substantial challenges challenges to water quality management. Degradation experiments revealed limited biodegradability of DOM (15 % over 28 days) and minimal photodegradation (13.5 % over 72 h), with more than 80 % remaining in a refractory state. Spectroscopic analyses revealed compositional shifts in DOM with prolonged WRT, characterized by decreased humic-like substances and increased protein-like compounds, indicating a progressive transition from allochthonous to autochthonous DOM dominance. BSEM analysis identified a significant temporal shift in DOM drivers: during the initial phase (1992–2010), human activity pressure (HAP) and riverine input quality (RIQ) collectively explained 70 % of the variance, with natural drivers contributing less than 20 %; whereas in the subsequent phase (2010–2023), anthropogenic influences diminished as hydrological and climatic factors became predominant, with hydrological regime (HR) and climatic factors (CF) jointly accounting for 87 % of RDOM variance, reflecting a transition from anthropogenic to climate-hydrological driven accumulation patterns. This research underscores the critical role of hydrological residence time in determining DOM composition, sources, and persistence in plateau lakes following partial decoupling of external pollution sources. The findings highlight the dual influence of climate and hydrology on lakes experiencing significant pressures from reduced water resources and increasing water demand, challenging conventional management strategies focused exclusively on external nutrient control. The case of Lake Erhai demonstrates the necessity for integrated management approaches that address both external and internal DOM dynamics to support sustainable water quality and ecosystem integrity.</div></div>","PeriodicalId":356,"journal":{"name":"Journal of Environmental Management","volume":"386 ","pages":"Article 125813"},"PeriodicalIF":8.0,"publicationDate":"2025-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144070685","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We set up a factorial experiment that manipulated the introduction of field collected soil microbes, the salinity of these introduced microbes, and the salinity of the water in which plants were grown (freshwater vs. saltwater). To identify the impact of native microbes on the survival of plants in high stress environments, specifically we examined how a <em>Liatris spicata</em>, a freshwater plant would germinate and grow in salt environments. The overall germination of <em>L. spicata</em> showed that native microbes from high salinity sites positively affect the growth of plants in saltwater. Germination rate was significantly higher (25.8 %) in plants with microbes compared to control plants. Both saltwater exposure and microbial presence had a significant effect on plant growth, suggesting that the impact of saltwater on plant growth depends on the presence of microbes.

Results showed that the MW fractions of DOM from the onset of the dry season were higher than those before flooding.

The driving force behind this study is to investigate the spillover effects of socio-governance factors on the CE transition, focusing on the role of contract monitoring. Panel data encompassing 16 EU countries that have made limited progress in meeting their greenhouse gas emission targets from 2010 to 2019 are utilized for the analysis. To estimate the spatial spillover effects, various models including spatial Durbin models, spatial lag regression models, spatial error models with spatial and time fixed-effects, spatial autocorrelation and mixed-effects ML and REML regression models are employed. Findings reveal that robust contract monitoring plays a significant role in enhancing CE, emphasizing that transparent public procurement and accountable decision-making are key drivers of the circular transition. Legal frameworks that protect property rights and promote regulatory quality further facilitate CE adoption, with positive spatial spillover effects suggesting that well-governed countries indirectly encourage CE implementation in neighboring countries. Conversely, stringent environmental policies lead to regulatory arbitrage, in line with the \"pollution haven hypothesis,\" as waste-intensive industries relocate to jurisdictions with weaker enforcement, undermining collective CE efforts. The results highlight that governance structures not only act as domestic CE drivers but also as external factors influencing regional environmental outcomes. The study advocates for the harmonization of regulatory standards and enhanced contract monitoring mechanisms across the EU to prevent cross-border regulatory evasion. Strengthening social cohesion is also found to amplify these effects, underscoring the importance of multi-dimensional socio-political foundations for a successful and cooperative CE transition.</div></div>","PeriodicalId":356,"journal":{"name":"Journal of Environmental Management","volume":"386 ","pages":"Article 125828"},"PeriodicalIF":8.0,"publicationDate":"2025-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144070550","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study was undertaken with no maturation period to consider the worst-case scenario corresponding to the period just after filter skimming. Agitating the surface and restarting flow released captured particles, some moving downward through the filter. Shallow filter depths resulted in particles appearing in the filtrate, but increasing the media depth beyond 500 mm minimized this effect. Since 90 % of headloss occurred in the upper layers, deeper particle penetration was insignificant. Increasing the hydraulic loading rate from 0.3 to 0.5 m/h reduced particle retention by 0.72 log, yet all abiotic SSFs achieved over 2 log particle capture. Small particles (2–10 μm) were removed by 2 logs, indicating sufficient non-viral pathogen retention under routine conditions. Effective capture of particles sized 2–125 μm suggested minimal risk to water quality and public health during UWS on full-scale SSFs. Using clean sand and kaolin represented a worst-case scenario, excluding biological maturation and particles.

Therefore, monitoring and managing water resources by assessing comprehensive surface runoff (SR) potential is crucial instead of relying on broad sub-watershed (SW) generalizations. This study aims to identify the characteristics of landscape evolution and hydro-physical factors that influence SR. It prioritizes the SR potentials of SWs by examining multi-dimensional aspects of hybrid MCDM models integrated with ensemble machine learning techniques. Findings show SW shapes vary from elongated (0.57) to oval (0.87). Stream length ratios ranging from SW4 (0.61) to SW5 (9.99) indicate diverse slope magnitudes and geomorphic development stages. Moderate drainage densities (0.65–0.89 km/km²) indicate underlying litho-structural influences on drainage networks. Low to moderate drainage textures (1.33–2.33) suggest potential SR zones, mainly due to the Proterozoic gneissic complex dominance. Landscape evolution analysis shows SWs are at an early mature stage (average 0.49). The prioritization results from the hydro-morphotectonic (MPT) and hydro-physical (HYP) TOPSIS and VIKOR integrated extra trees regression (ETR) models achieve the best accuracy, followed by XGBoost, Bagging, and Voting models.
