This study aimed to develop an innovative integrated index for river water quality and ecological risk (RWQI) and evaluate its applicability in the Gharehsoo River. The proposed RWQI, for the first time, provided a unified framework for the simultaneous assessment of overall water quality (based on 16 physicochemical and microbial parameters) and the risk posed by heavy metals. In this regard, the first step involved analyzing water quality for various uses (drinking, recreation, wildlife, industry, and agriculture) using the Enhanced River Pollution Index (ERPI) across seven stations over two seasons. Subsequently, the performance of Multiple Linear Regression (MLR) and Support Vector Regression (SVR) models in predicting the values of these indices was examined and compared. Finally, the combined RWQI was calculated based on the same dataset, and uncertainty analysis of the models was performed using the Markov Chain Monte Carlo (MCMC) method. Descriptive statistical analysis (based on ERPI-DD calculations for 14 samples from 7 stations across two seasons) revealed that the water status of the Gharehsoo River is critical for drinking purposes, with 64.28% of the samples classified as “unsuitable” according to the DD index (drinking without treatment). In contrast, water quality for wildlife and fisheries (WF) was evaluated as “good to excellent” for 100% of the samples based on Central Pollution Control Board (CPCB) standards and the ERPI-WF model. The SVR models with polynomial and Radial Basis Function (RBF) kernels demonstrated very high predictive accuracy in estimating the ERPI values (as the reference criterion) for various water use categories, with coefficients of determination (R²) approaching 1 in many cases. Furthermore, the RWQI effectively identified critical points; for example, the Samian station was determined to be a critical point for recreational use (swimming). Uncertainty analysis also revealed that the RWQI model exhibits higher uncertainty compared to other models, primarily due to the inherent complexity of the model and the incorporation of combined pollutant risks. Consequently, the developed RWQI index proved to be a powerful tool for integrated monitoring of water quality and ecological risk assessment in river management, enabling the adoption of more targeted protection strategies.</p></div>","PeriodicalId":543,"journal":{"name":"Environmental Management","volume":"76 10","pages":""},"PeriodicalIF":3.4,"publicationDate":"2026-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149102514","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}

Increasingly, these trees have been exhibiting stress symptoms, including canopy dieback, browning of foliage tips, defoliation, and reduced needle length. Previous research has shown that these symptoms may be the result of predisposing abiotic stressors, such as extreme weather events, soil compaction, and proximity to urban infrastructure. Building on this, the present study examines the trees’ foliar fungal communities and potential pathogens. Thirty-two (32) mature <i>A. heterophylla</i> trees of varying health growing on the foreshores of Gold Coast, Australia, were selected for isolation of fungi from foliage samples. Sixteen fungal species from ten families were identified. <i>Neofusicoccum luteum</i>, the most commonly represented species and previously unreported in <i>A. heterophylla</i>, was isolated from eight trees (25%) and selected for six-week-long pathogenicity testing under controlled glasshouse conditions. To assess pathogenicity, forty two-year-old trees were inoculated with either <i>N. luteum</i> or sterile agar (control). Half of these trees received limited water, and the other half was watered regularly. The infection rate exceeded 90%, and lesions developed in both groups, but lesions in the control groups were significantly smaller (<i>p</i> &lt; 0.05) than in trees inoculated with <i>N. luteum</i>. Re-isolation at the end of the pathogenicity tests had a higher success rate in drought-affected trees (75%) despite the smaller size of the lesions. Although no mortality occurred, trees inoculated with the pathogen were significantly (<i>p</i> &lt; 0.05) shorter than the control trees under the regular water conditions. These results suggest that <i>N. luteum</i> may contribute to <i>A. heterophylla</i> decline and reduced growth rate, but is unlikely to be the sole causal agent and is unable to kill a tree rapidly. Strategies for improving <i>A. heterophylla</i> health and management emerging from this study include the need for: (a) supplem.entary irrigation during prolonged drought to prevent the pathogen from entering through damaged bark; and (b) consistent tree health monitoring.</p></div>","PeriodicalId":543,"journal":{"name":"Environmental Management","volume":"76 10","pages":""},"PeriodicalIF":3.4,"publicationDate":"2026-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13619678/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149073081","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hence, planning energy infrastructure requires a thorough understanding of the behavior and habitat requirements of affected species during critical phases of the annual cycle. We assessed the energetic consequences of losing agricultural foraging habitat for a wintering goose species with a high degree of site-fidelity. Proposed renewable energy developments, specifically wind turbines and solar panels, pose a risk of losing winter cereal fields, which are the prime foraging habitat for the geese during cold spells. Using estimates of energy intake and expenditure derived from GPS-tagged individuals, we simulated body mass development under cold conditions with and without access to winter cereals as well as under mild conditions with pastures only. Across all cold winter scenarios, simulated body mass decreased, reflecting lower energy intake as well as increased thermoregulatory costs, and energetic deficits intensified when winter cereals were unavailable. Under mild winter conditions, body mass could be maintained without access to winter cereals. These results demonstrate that habitat loss has considerable energetic consequences for wintering geese under cold winter conditions. More broadly, our findings underscore the need to assess land-use change in the context of both resource availability and environmental conditions. Ensuring access to high-quality foraging habitats during energetically challenging conditions should therefore be prioritized in spatial planning. Where habitat loss is unavoidable, alternative habitats must provide comparable resource quality, low disturbance, and behavioral compatibility, particularly for site-faithful species.</p></div>","PeriodicalId":543,"journal":{"name":"Environmental Management","volume":"76 10","pages":""},"PeriodicalIF":3.4,"publicationDate":"2026-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13615994/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149056810","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We synthesized data from 221 peer-reviewed studies from 1988 to 2024 to evaluate the global effects of six sustainable land management (SLM) practices—organic amendment, inorganic fertilization, integrated fertilization, conservation tillage, crop diversification, and crop residue management—on SMBC in global croplands. Except for inorganic fertilization, which had a slight negative effect, all practices were associated with higher SMBC concentration values, with treatment plots exhibiting, on average, 23.5% higher SMBC concentration than control plots across the compiled global database. The degree of these effects varied on the basis of environmental factors, especially aridity and soil texture. Based on the compiled dataset and extrapolation approach, SLM practices were associated with an estimated 27% increase in global SMBC stocks, corresponding to approximately 322 million tonnes of microbial carbon across global croplands although this estimate should be interpreted with caution due to spatial heterogeneity in data coverage and uncertainties associated with generalized assumptions in bulk density and soil depth. Integrated fertilization and crop diversification were particularly effective across all aridity classes. Subgroup analyses confirmed that soil texture, aridity, and management practices each significantly affected SMBC. However, we observed notable combined effects on SMBC only when two environmental factors changed at the same time. This suggests that although SLM practices may help to reduce the harms of single stressors, the combined effects of multiple stressors can greatly change microbial carbon dynamics. These findings highlight the importance of developing context-specific SLM strategies to enhance microbial carbon pools and improve soil health, thereby providing guidance for land managers, policymakers, and farmers to promote more resilient and sustainable agricultural systems worldwide.</p></div>","PeriodicalId":543,"journal":{"name":"Environmental Management","volume":"76 10","pages":""},"PeriodicalIF":3.4,"publicationDate":"2026-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149035145","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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 results show that within the year of application, probability of FAV presence reduced as herbicide application rate increased. Both herbicide treatments were most effective in slow-flow shallow open-water habitats, and least effective in fast-flowing channel habitats.

We explored a method for decomposing trading ratios into environmental equivalency, delivery ratio, and uncertainty component for different sources, and considering the co-benefits of watershed mitigation. Our results demonstrate that prioritizing diffuse nitrogen sources with a greater aquatic environmental impact and co-benefits can significantly reduce the watershed mitigation requirements for offsetting the environmental impacts of point-source nitrogen loads.

In reservoirs, land cover characteristics (i.e., intensive agriculture and fallow land) within the 100 m buffer zone emerged as dominant drivers of phytoplankton and Chl-a variability. Principal Component Analysis revealed four distinct typological groupings for both system types, reflecting the interplay between morphological and land use metrics.
