We used forest inventory data from 136 plots across nine fragments with different land-use histories. Environmental variables and taxonomic and functional diversity indices were obtained at the plot level. We explored the relationships between the variable sets and diversity by building linear mixed-effects models (LMM), in which land-use history was included as a random effect in all models, while the remaining variables were grouped as fixed effects. The fragments were dissimilar, and taxonomic and functional diversity indices values were heterogeneous. The LMM showed varied performance among the variable groups and diversity indices, with greater influence from random effects, while climatic and anthropogenic models stood out among the fixed effects. Taxonomic indices showed similar patterns, with greater explanation by precipitation and temperature, while other models had low explanatory power. Functional indices were more influenced by climatic and anthropogenic variables, although random effects remained predominant in explaining total variance. Anthropogenic variables related to land-use history and time since abandonment, as well as climatic variables related to temperature, precipitation, and water deficit, are the main drivers of taxonomic and functional diversity in Brazilian Atlantic Rainforest fragments.","PeriodicalId":356,"journal":{"name":"Journal of Environmental Management","volume":"392 ","pages":"126830"},"PeriodicalIF":8.4,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144811565","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}

While climate policy is expected to catalyze green investment, transition-related risks often produce asymmetric pricing dynamics across sectors and return distributions. This study investigates how European transition risks are transmitted and priced within international clean energy subsectors by employing two advanced quantile-based econometric techniques-Cross-Quantilogram (CQ) and Wavelet Cross-Quantile Correlation (WCQC). Using high-frequency data from NASDAQ OMX Green Economy subsector indices spanning October 15, 2010 to December 29, 2025, the analysis reveals persistent, nonlinear, and time-varying relationships between transition risk and sectoral returns. Notably, clean energy subsectors such as solar, wind, geothermal, and fuel cells exhibit consistent and significant negative dependence in lower and median quantiles, indicating heightened vulnerability to downside shocks. In contrast, subsectors like energy storage and developer/operator show mild but positive sensitivity in upper quantiles, reflecting a selective reward mechanism for firms perceived as resilient and adaptive. These results suggest that transition risk is not uniformly priced and that sectoral responses are shaped by both policy uncertainty and firm-level dynamics. The findings highlight the complexity of climate-financial interconnectedness and emphasize the need for sector-specific, coherent policy frameworks to ensure that climate ambition translates into stable and equitable market outcomes.","PeriodicalId":356,"journal":{"name":"Journal of Environmental Management","volume":"392 ","pages":"126936"},"PeriodicalIF":8.4,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144815519","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}

Carboxymethyl Salix powder membrane (CMSM) was subsequently prepared through wet spinning technology. The swelling properties of CMSM were investigated. The results showed that the swelling degree reached the maximum at 45 min, pH 5, temperature of 65°C, and a NaCl concentration of 0.04 mol/L, reaching 7.95 g/g. Through model fitting, it was found that CMSM fits well with the Fickian diffusion model in the early stage, while the entire swelling process fits well with the Schott model. Characterisation results indicate that the structure of CMSM is loose, porous, and uneven on the surface. This structure facilitates the diffusion of water molecules and enhances the water absorption performance of CMSM. The structure of CMSM is similar to the disordered structure of glass or plastic, presenting an amorphous structure. Additionally, CMSM exhibits good thermal stability. By regulating the swelling behaviour of CMSM, this study can develop innovative membrane materials with environmental responsiveness and multifunctionality, promoting the application of green and sustainable materials and providing theoretical support for the design of new composite membranes.","PeriodicalId":12009,"journal":{"name":"Environmental Technology","volume":" ","pages":"4227-4236"},"PeriodicalIF":2.0,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144247137","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

Understanding the mechanisms that reconcile these seemingly opposing properties is limited by the transient nature of evolutionary processes, where past pathways and contexts are often lost. Here, we overcome this limitation by tracing the biochemical evolution of avian carotenoid networks on the global carotenoid biochemical network, which is unmodified in avian evolution. By mapping enzymatic interactomes of 260 extant bird species and their reconstructed ancestral states onto this global network, we reveal that stepping stones between them are evolutionarily stable degenerate carotenoids-compounds that can be synthesized interchangeably by different dietary carotenoid-specific pathways. We find that ecological specialization across taxonomic groups is consistently associated with an uneven biochemical reach of individual dietary carotenoids, leading to increased fragmentation and reduced resilience of enzymatic networks to failure. However, the robustness of enzymatic networks of specialized groups is restored by the accumulation of degenerate carotenoids. This accumulation enables direct transitions between ecological specializations and sustains evolutionary explorations. Thus, the same feature of network structure-its degeneracy-increases the robustness of specialized enzymatic networks as enables evolutionary transitions between them. These findings provide an insight into the mechanistic basis for the interplay between natural selection and historical contingency, highlighting their fundamental interdependence.","PeriodicalId":50800,"journal":{"name":"American Naturalist","volume":"206 3","pages":"218-230"},"PeriodicalIF":2.7,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144859867","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}

All materials exhibited good adsorption capacities (75-170 mg g-1), with biochar outperforming coal ashes due to higher carbon content. Adsorption capacity showed a decline with increasing temperature and humidity of maximum 30 %, consistent with exothermic physical adsorption. Freundlich isotherms best described the adsorption behaviour, suggesting a non-linear, reversible, and multilayer process. Column adsorption tests of TCE vapours were then carried out with biochar to assess the adsorption behaviour under dynamic conditions showing good performance. Modelling revealed that a 50 cm thick barrier of biochar could effectively mitigate chlorinated vapours for over 15 years for entering concentrations up to 1 g m-3, proving the suitability of the tested materials as long-term risk management solutions in the subsurface.

This study investigates the nonlinear impact of artificial intelligence computing power (AICP) on the green transformation of 251 Chinese energy enterprises from 2010 to 2023. Results reveal a statistically significant U-shaped relationship: AICP initially inhibits green transformation due to high costs and inefficiencies but later promotes it by enhancing environmental and operational performance. Public environmental awareness is found to moderate the nonlinear relationship. A high levels of concern can alter the curvature of the U-shape, sometimes leading to symbolic rather than substantive green actions, thereby weakening AICP's positive effects. Heterogeneity analysis shows the U-shaped effect is stronger in non-state-owned enterprises and in firms located in low-carbon pilot cities, indicating that ownership structure and regional policy context shape AI-driven sustainability outcomes. Additionally, threshold regression results reveal that when the carbon disclosure index exceeds a critical value, the relationship between AICP and green transformation becomes an inverted U-shape.

A significant source of MPs is the land application of sewage sludge as a soil amendment. Once released into the environment, MPs are difficult to remove due to their small size, chemical persistence, and widespread distribution. Phytoremediation offers a sustainable strategy for in situ soil remediation, employing plants to extract, stabilize, or degrade pollutants. However, its application to MPs removal remains largely unexplored. Here, we investigated the capacity of the fern Pteris vittata to absorb MPs from soils amended with sewage sludge. We show that P. vittata is able to uptake, through the roots, MPs derived from different types of plastic polymers commonly detected in the environment, including PE, PP, PA, PU, PET, PVA, PS, EVA, PMMA and ABS. Among them, PE, PA, PP, PU, PET, PVA, EVA and PVC were translocated to the fronds. Furthermore, MPs content in roots and fronds increased with the amount of sewage sludge in the soil. Biometric index analyses show that roots and fronds growth is reduced in plants treated with increasing concentrations of sewage sludge. The expression of the oxidative stress related genes CAT, SOD, APX, and of the aquaporins NIP6.1 and PIP2.8, is repressed in roots but not in fronds, suggesting localized physiological stress induced by MPs. This study provides the first evidence that P. vittata can uptake MPs via roots and translocate them to aboveground tissues, supporting its potential use for MPs phytostabilization or phytomanagement strategies.","PeriodicalId":356,"journal":{"name":"Journal of Environmental Management","volume":"391 ","pages":"126548"},"PeriodicalIF":8.4,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144635870","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}
