However the poly modifiers and rejuvenators produce risks to the environment and limit high-proportion RAP application, therefore, this study investigates the natural mineral, Qingchuan rock asphalt (QRA) and Shengzhou diatomite (SD), to improve high-RAP-proportion mixtures performance. Firstly, microscopic tests were conducted to elucidate the modification mechanism via DSC, SEM and FTIR. Then, binders conventional properties were performed and mixtures road performance tests were conducted. Finally, Gray Correlation Analysis (GCA) combined with Entropy Weight Method (EWM) was employed to reveal the optimal dosage and correlation degree between modifiers and performance of high-RAP-proportion mixtures. The results demonstrated that the modified binders incorporating SD and QRA exhibited improved thermal and structural stability. SD could significantly improve the low-temperature performance, but QRA acted as a brake in a certain range. However, SD, QRA and RAP substantially improve the high-temperature performance, which enhance the dynamic stability nearly nearly sixfold. Conversely, SD reduces BPN by about 10 %, while QRA can enhance it by up to 20 %. Meanwhile, moisture stability reduced a lot by the large contents of RAP, but SD and QRA significantly improved it and SD played a crucial role in the anti-freeze-thaw performance. The best performing combination was D10Q10, while the worst was D10Q5, which manifested the QRA-SD-RAP synergistically improving the road performance. The coupling effect of natural mineral QRA and SD provides a comprehensive performance enhancement and strategy for solving high-proportion RAP applications.</div></div>","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"522 ","pages":"Article 146185"},"PeriodicalIF":10.0,"publicationDate":"2025-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144763854","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

However, much of conservation science is dominated by the use of a single metric, species richness, despite several known limitations. Here, we review and synthesize why species richness (i.e., the number of species in a local area) is a poor metric for a variety of topical- and policy-relevant conservation problems. We identify the following three key issues: (1) increasing evidence emphasizes that species richness is often not a robust metric for identifying biodiversity change, (2) species richness ignores species identity and so may often not reflect impacts on species of concern, and (3) species richness does not provide information needed on the persistence of biodiversity or the provision of ecosystem services. We highlight the unappreciated practical outcomes of these limitations with examples from three ongoing conservation debates: whether local biodiversity is declining, how habitat fragmentation affects biodiversity, and the extent to which land sharing or sparing is more beneficial for biodiversity conservation. To address these limitations, we offer a set of guidelines for the use of biodiversity metrics in conservation policy and practice.</p>","PeriodicalId":157,"journal":{"name":"Conservation Letters","volume":"18 4","pages":""},"PeriodicalIF":7.7,"publicationDate":"2025-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/conl.13124","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144764120","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

The MSFD follows a 6-year cycle, with assessments made based on 11 descriptors linked to specific pressure, state and impact-related criteria. Member States assessments should determine the extent to which GES is achieved. However, for coherent management of EU seas, comparable assessments across Member States and EU-wide overview of the status and MSFD progress are essential. This study developed pressure, state, and impact indices, by integrating available MSFD data reported by EU Member States. For the first time, MSFD data across all descriptors have been integrated to produce a European regional assessment. Findings indicate that most European regions are far from demonstrating GES, suffering from intense pressures and impacts.

This study introduces an innovative synthesis of ZnS/ZnO nanocomposites (NCs) from ZnS nanoparticles (NPs) for environmental remediation. Aqueous colloidal solution of ZnS NPs (10 g/L) was oxidized in an airlift photoreactor (5 L) at room-temperature using ozone (O₃) and ozone/ultraviolet (O₃/UV), respectively. The effects of pH (3-11), time (10-90 min), and oxidation modes were explored on oxygen content (OC) of NCs. The optimization results using RSM showed that higher pHs and longer reaction times led to increased OC of NCs up to 7.14 and 11.12 wt% in O₃ and O₃/UV oxidation, respectively. Interaction of O₃/UV and ZnS exerts a dual-effect involving O₃-induced oxidation of ZnS, and promoted-photocatalytic role of ZnS precursor (auto-photocatalytic effect). This effect facilitates ZnS to ZnO conversion and enhances reaction kinetics across a broader pH range. Optical bandgap analysis revealed a decrease in the bandgap energy from 3.70 eV for ZnS NPs to 3.41 eV for ZnS/ZnO NCs synthesized under O₃/UV (pH: 11 and time: 90 min). The proposed method was subsequently applied to spent ZnS NPs, yielding in ZnS/ZnO NCs with an OC of 9.32 wt%. The NCs synthesized from virgin and spent ZnS NPs were used for photocatalytic degradation of Congo red dye and the efficiencies of 91 and 98 % were achieved, respectively.
