Although native seed mixes are increasingly used in post-disturbance revegetation, long-established road verges outside urban areas are often overlooked for proactive conservation. To promote species-rich and heterogeneous vegetation, we established vegetation islets by sowing a specifically designed seed mix of native herbaceous species along long-established road verges in a semi-arid Mediterranean agricultural landscape across two experimental blocks with different sowing years. Over four years, we conducted an integrated assessment of seed mix performance and plant diversity, composition, and structure, comparing vegetation islets and control plots and exploring the influence of local edaphoclimatic conditions. The establishment of vegetation islets had the strongest observed effect on plant composition and diversity, locally adding sown and spontaneous species absent from controls, and increasing species richness and compositional heterogeneity. Although seed mix persistence and relative cover declined over time, composition remained distinct from controls, shifting from annual to perennial dominance. Vegetation islets supported denser, shorter vegetation, enhancing local structural heterogeneity without compromising road safety. Higher rainfall, lower temperatures, and lower soil nutrient levels were associated with higher seed mix persistence and species richness. Experimental block affected only species composition and seed mix relative cover. An appropriate bespoke native seed mix, applied to stable long-established plant communities, helped support reliable conservation outcomes under semi-arid Mediterranean conditions. Vegetation islets may offer a resource-efficient approach to promote plant diversity and habitat heterogeneity in long-established road verges, highlighting their potential for proactive conservation.</div></div>","PeriodicalId":356,"journal":{"name":"Journal of Environmental Management","volume":"418 ","pages":"Article 131080"},"PeriodicalIF":9.2,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149101752","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

Using a C57BL/6J mouse model of maternal PM_2.5 exposure via intranasal instillation (3 mg/kg body weight, every other days from gestational day 0.5 to 17.5), we investigated the mechanisms underlying PE-like phenotypes induced by heating-season PM_2.5 from northern China. Exposed pregnant mice exhibited significantly elevated blood pressure at E13.5 and E17.5, accompanied by reduced vascular endothelial growth factor (VEGF) and placental growth factor (PLGF) levels, increased urinary protein, and elevated serum levels of the tumor necrosis factor α (TNF-α), interleukin-6 (IL-6), and soluble fms-like tyrosine kinase-1 <strong>(</strong>sFLT-1). Conversely, the endothelial markers endothelin 1 (ET-1) and nitric oxide (NO) remained unchanged.

This study proposes a site-specific, kinetics-based framework for operational assessment of full-scale wastewater ozonation using fluorescent tracers (FTs) selected from non-spiked fluorescent compounds present in treated wastewater. The FTs were quantified by liquid chromatography with fluorescence detection without solid-phase extraction, and their residual fractions were linked to oxidant exposure through reaction rate constants with ozone and hydroxyl radicals. Among 12 candidate peaks detected at one full-scale wastewater treatment plant, six compounds were selected as FTs after excluding peaks that increased after ozonation, were potentially affected by particle or intracellular elution or formation reactions, or showed insufficient 24 h stability. A simple non-ideal residual fraction model developed for the full-scale ozone contactor reproduced the residual fractions of these six FTs and predicted the residual fraction of <em>Escherichia coli</em>, which was not used for model calibration, with absolute errors of 0.04–0.10. Conventional indicators, including absorbance at 254 nm and total organic carbon, weakly correlated with the estimated oxidant exposure parameters. These findings suggest that bulk water-quality indicators alone may be insufficient for quantitatively characterizing ozonation performance.

Which structural conditions determine where governance-activated transition episodes, meaning country-years in which climate adaptive capacity is improving while labour market pressure on trafficking-affected populations remains elevated, concentrate across the global income distribution? Using data on 192 countries from 2000 to 2023, we build the Job and Trafficking Pressure Index (JTPI) to detect these episodes and test what structural conditions predict where they concentrate, using several statistical approaches that check the pattern from different angles. Countries with rising climate governance capacity are consistently more likely to show these transition episodes than countries without it, a result that holds across every method we use and confirms that JTPI is capturing a real and meaningful pattern rather than statistical noise. This pattern is strongest and most reliable in Upper-Middle Income economies, while the poorest countries lack sufficient data on climate readiness and labour markets to support firm conclusions. When we ask which countries experience this pattern most intensely, three features stand out. Larger populations, greater openness to trade, and higher rates of urbanisation are the strongest predictors, pointing to a specific mechanism. Climate investment tends to create new formal jobs in cities and trade sectors, and it is in these growing urban and trade-dependent economies that trafficking-affected workers appear to be drawn into the formal labour market in the largest numbers. They answer the question posed at the outset. Governance-activated transition episodes concentrate in populous, trade-open, urbanising economies rather than uniformly across the income distribution. This gives national adaptation plans, climate finance conditionality frameworks, and anti-trafficking governance bodies a specific structural target rather than a general policy aspiration.</div></div>","PeriodicalId":356,"journal":{"name":"Journal of Environmental Management","volume":"418 ","pages":"Article 131049"},"PeriodicalIF":9.2,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149102181","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}

Particulate Fe concentration (Fe_SPM, g/kg) ranged from 26.27 to 168.79 g/kg, and δ⁵⁶Fe values varied from −0.94‰ to 0.17‰, with basin-wide means of 49.65 g/kg and 0.01‰, respectively.

Correlation analysis and Bayesian source apportionment suggested that agricultural land use was a major basin-scale control on Fe_SPM, accounting for approximately 45% of Fe_SPM in the Beixi River under wet-season conditions, whereas mining inputs were locally important in the Beixi headwaters and may have contributed to the depleted δ⁵⁶Fe signatures.

With severe spatial constraints in urban cores, suburban parks are increasingly prioritized for heat mitigation; yet, the cross-seasonal cooling efficacy and scale-dependent mechanisms of these peripheral green spaces remain critically underexplored. Unlike isolated urban parks, suburban parks are deeply embedded within a wider matrix of agricultural fields, natural vegetation, and wetlands, functioning as complex symbiotic systems. Targeting this gap, this study assesses the cross-seasonal cooling effects of 16 suburban parks and their surrounding land cover configurations in Hangzhou, China, using land surface temperature derived from single-year snapshots (based on meteorologically representative clear-sky observations) across four seasons in 2022. Four complementary indicators (cooling distance, area, intensity, and efficiency) were quantified to distinguish spatial extent from cooling strength. Spearman correlation analysis, Random Forest modeling, and K-means clustering were employed to identify dominant drivers and configuration-dependent patterns. The results show that suburban parks provided measurable cooling cross-seasonally, with peak intensity (mean 4.7 ± 1.5 °C) and spatial reach in summer. Cooling area increased consistently with park size, whereas cooling intensity and efficiency did not, indicating a non-linear scale–effect relationship. Surrounding land cover composition exerted stronger influence than park area alone, with driver importance shifting seasonally. Landscape typology analysis revealed that parks nested within farmland-dominated matrices maximized summer cooling, while heterogeneous water–farmland systems sustained more stable cooling across cooler seasons. While limited by the temporal constraints of specific clear-sky observations, these findings clarify seasonal variability, scale effects, and configuration-dependent cooling in suburban parks, providing actionable evidence for optimizing peri-urban green infrastructure within metropolitan thermal systems.</div></div>","PeriodicalId":356,"journal":{"name":"Journal of Environmental Management","volume":"418 ","pages":"Article 131027"},"PeriodicalIF":9.2,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149072963","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}
