This study presents a preliminary multidimensional framework for evaluating wild animal species which involves two analytical dimensions: productive potential (PP) and ecosystem potential (EP). The framework was applied to 60 species - most of which were from Latin America - to compare productive feasibility and ecosystem contributions among taxa. To evaluate PP, indicators related to reproduction, nutrition, production, market integration, and regulatory feasibility were used; to evaluate EP, indicators related to provisioning, regulating, supporting, and cultural ecosystem services were used. Data was compiled from scientific literature and analysed using scoring, k-means clustering, and principal component analysis (PCA). PP analysis identified two clusters, with invertebrates showing greater productive potential than vertebrates, whose use is constrained by biological and legal factors. EP analysis identified three clusters, which varied according to which of the following services they provided: nutrient cycling, waste decomposition, pollination, ecotourism, and symbolic values. An integrated PP/EP analysis identified six clusters, indicating both complementarities and trade-offs between productive use and ecological roles for all clusters. Overall, re- sults show that productive performance is not necessarily aligned with ecosystem sustainability, and that management decisions must be adapted to the particular ecological, legal, and socio-cultural contexts. This framework provides an initial step toward carrying out integrative wildlife assessments that may contribute to improving wildlife management, bioeconomic planning, and biodiversity conservation in diverse contexts.

    查看更多>>摘要：In many societies, men and women play diverse roles in environmental management and may consequently hold different, but often complementary, local knowledge. It is therefore key that knowledge systems of both men and women are considered in studies of community-based natural resource management and conservation decisions. However, due to social, economic, cultural and other factors, the local knowledge held by women is often less well-known, understood and applied in such groups. We aimed to help address this gap by collating case studies of community-based wildlife management (CBWM) groups from across the globe that demonstrated a level of participation by women that allowed them to share their knowledge with community-based wildlife management group decision-makers. Focusing on 32 selected case studies, we aimed to explore three main themes: (ⅰ) The application of women's knowledge in resource management practices; (ⅱ) Ways in which women's knowledge was shared; and (ⅲ) How these inputs impacted wildlife conservation outcomes. We found for most of the case studies that women's participation contributed to positive conservation outcomes as measured by their group's fulfilment of one or more of the 2023 CBD Kunming-Montreal Global Biodiversity Conservation Framework goals for 2050. These included positive outcomes for species conservation, habitat restoration, equitable sharing of benefits, and for investment by and collaboration with external experts and organisations. We suggest that the greater inclusion of women in community-based wildlife management groups, at a level where they can actively share their knowledge with policy and decision-makers, is key to advancing equity and conservation effectiveness of community-based wildlife management groups.

    查看更多>>摘要：MgO solidification carbonation technique is a low-carbon and efficient green modification method, but it is not clear on how to analyze the carbonation degree and carbon absorption capacity of carbonated soil. The quantitative analysis system of carbon absorption capacity of MgO solidification carbonation soil was established by quantitatively measuring the CO_2 absorption and unidirectional carbonation depth of MgO solidification carbonation soil under the conditions of different MgO contents and carbonation time. The macro and micro mechanism of carbonation process from the perspective of carbon absorption was explored, and the reasons for slowing down of carbonation reaction in the carbonation process were analyzed. The test results show that increasing the MgO content promoted the specimen to absorb more CO_2, and the specimen was fully penetrated in a shorter time. The degree of carbonation reaction can be determined by the decreasing trend of water content. The lower the MgO content was, the longer the carbonation time was required for the fully penetrated specimen. The fitting results showed it only took 2 h to fully penetrate when the MgO content was 9.48 %, but it was difficult to fully penetrate when the MgO content was less than 3 %. With the progress of carbonation reaction, increasing MgO content can improve the carbonation rate decreased, and the carbonation proportion and carbonation density simultaneously, up to 126 kg/(h•m~3 ), 0.79, 197 kg/m~3 . It was estimated that the waste soil in the shield section of Jiangyin Jingjiang Yangtze River tunnel can absorb up to 760,000 tons of CO_2, which was equivalent to the carbon emission from the production of 950,000 tons of quicklime.In the deepening period of carbonation reaction, MgO/Mg(OH)_2 was wrapped and cannot participate in the reaction, resulting in the soil cannot be completely carbonated.

    128627.1-128627.16页
    查看更多>>摘要：Diethyl phthalate (DEP), a representative phthalate ester known for its environmental persistence and endocrine- disrupting effects, poses a significant challenge in wastewater treatment. To address this, a dielectric barrier discharge (DBD) plasma system coupled with solvent-regulated BiOBr catalysts was developed for efficient DEP degradation. Following catalyst screening and process parameter optimization, the system achieved approximately 19 % higher degradation efficiency compared to the non-catalytic plasma process. The layered structure and favorable band alignment of BiOBr facilitated charge transfer and oxygen activation under plasma excitation, resulting in a pronounced plasma-catalyst synergy that accelerated oxidative decomposition. Electronic- structure analysis further revealed that the Bi-O-Br orbital configuration promoted the continuous generation of reactive oxygen species. These findings elucidate the intrinsic coupling mechanism between plasma discharge and catalyst surface reactions, offering new insights for designing efficient plasma-assisted systems for organic wastewater purification.

    128671.1-128671.12页
    查看更多>>摘要：This study aimed to develop an innocuous and sustainable strategy for the utilization of black liquor generated from ethylenediamine pretreatment of corn straw by employing it as the sole nitrogen source during composting. The effects of exogenous bacterial agents (Bacillus subtilis, Bacillus amyloliquefaciens, and Bacillus megaterium) on composting performance were evaluated. The results showed that composting with black liquor and bacteriological agents achieved maturity indicators comparable to those of conventional urea-based composting, including pH, nutrient content, germination index, and C/N ratio, while exhibiting a higher humification degree. Organic matter degradation was enhanced, and the final compost met the standards for organic fertilizers after 42 days. Microbial analysis indicated that black liquor application altered the community structure, with increased abundance of Firmicutes and enrichment of functional genera associated with nitrogen transformation. Overall, this study demonstrates that black liquor can effectively replace urea as a nitrogen source in composting, providing a feasible pathway for waste valorization and supporting circular economy and green agricultural practices.

    Solar-activated persulfate removal of bisphenol S from water: Kinetics, mechanism, transformation products, toxicity and pilot-scale evaluation

    查看更多>>摘要：Bisphenols are often detected in environmental samples and are implicated as endocrine-disrupting compounds. This study examines the photodegradation of bisphenol S (BPS), a common replacement of bisphenol A, using a solar-activated persulfate (solar/PS) system at batch and pilot scale. The photodegradation of BPS followed pseudo-first-order decay; the observed kinetic constant increased with oxidant concentration up to 0.19 min- 1 at 500 μg L~(- 1) and decreased as the initial BPS concentration increased (0.0091 min- 1 at 3 mg L- 1 ). The system's efficiency was approximately three times lower under alkaline conditions, while the apparent kinetic constant significantly decreased in secondary effluent. Interestingly, complete BPS removal was achieved in the pilot reactor under natural sunlight at approximately 20 kJ L- 1 . Based on scavenging experiments and electron paramagnetic resonance (EPR) spectroscopy, the degradation was driven by the synergistic action of sulfate radicals (SO_4~ (•-) ), singlet oxygen (~1O_2), and hydroxyl radicals (HO~• ). Five transformation products (TPs) were identified by LC/TOF-MS, and a plausible pathway is proposed. According to the ECOSAR model, some TPs exhibited higher predicted toxicity than the parent compound for certain indicators, suggesting the need for longer treatment times or more intensive conditions. Seed-based assays showed inhibition by BPS alone, while solar/PS treatment generally attenuated the toxicity of the mixture of BPS and TPs. Nevertheless, residual, time- dependent inhibition persisted in some species, underscoring species-specific risks and the need for multi- bioassay evaluation before reuse.

    Organic waste and their respective hydrochars: Characteristics, carbon stability and nutrient release dynamics in soil

    128674.1-128674.9页
    查看更多>>摘要：Hydrothermal carbonization (HTC) is a suitable treatment to valourize the organic matter and nutrient content of organic waste. However, the characteristics of the resulting hydrochars and their potential to act as organic fertilizers and soil amendments depend on nutrient transformations during HTC. Hydrochars were produced at 210 ℃ from five different feedstocks (pulp bio-sludge, digested and undigested sewage sludge, food digestate and cattle manure) and characterized. Hydrochars showed lower hydrogen-to-carbon and oxygen-to-carbon ratios than their respective feedstocks. Total nitrogen content decreased after HTC, with associated reductions ranging between 44 % and 67 % for manure-based and sewage sludge hydrochars, respectively. In a 120-day soil incubation with feedstock and hydrochar treatments, carbon dioxide (CO_2-C) emissions, net nitrogen mineralization and water-extractable phosphorus (WEP) were monitored. Hydrochars were applied to soil either alone or in combination with NH_4NO_3 fertilizer. Hydrochars led to reduced CO_2-C emissions compared with the feedstocks, while the addition of mineral nitrogen did not systematically affect cumulative CO_2-C emissions from hydrochar-treated soils. Net N mineralization of the materials decreased in the order feedstock > hydrochar > hydrochar + mineral N. Tested hydrochars did not negatively affect radish seed germination, but plant growth decreased during the first three weeks of a pot trial, indicating N limitation in sewage sludge- and manure-based hydrochar treatments. Hydrochars may therefore serve as suitable amendments where C retention and soil conditioning are prioritized but may be less effective as short-term N and P sources than the raw feedstocks.

    Evaluating the ecological effects of daily hydropeaking on lithophilous fish spawning habitat in a large mountainous river

    查看更多>>摘要：Water-level fluctuations caused by hydropower operations have the strongest effects in littoral zones, where they interfere with fish reproduction. Lithophilous species, which adhere eggs to gravel surfaces in these littoral zones, face heightened mortality as hydropeaking alternately inundates and exposes their spawning substrates. However, quantitative evidence connecting the intensity of hydropeaking with ecological impact of freshwater fish is still limited. This study addresses this knowledge gap by quantifying hatching success in fishes under daily hydropeaking conditions.Field experiments were conducted to determine the effect of dehydration duration on egg-hatching success, followed by the development of a water-level-fluctuation-based method to evaluate adhesive-egg spawning grounds and identify ecological thresholds for reservoir operation. Based on the effect of dewatering on fertilized egg survival, 6-h continuous exposure was identified as the ecological threshold for airexposure-induced egg mortality. The spawning-ground deactivation rate was then proposed, defined as the ratio of the deactivated area (≥6 h exposure) to the total potential spawning area. Finally, it is recommended that discharge variations during the reproductive period be limited to ≤2600 m~3 s - 1 and water-level fluctuations be restricted to ＜1.5 m, to ensure that the majority of spawning grounds maintain intact ecological functions. The study elucidates the ecological mechanisms governing lithophilous fish egg hatching under daily hydropeaking and proposes ecological thresholds for reservoir operation. Furthermore, it provides a quantitative framework for assessing how hydropeaking affects lithophilous spawning habitats.

    查看更多>>摘要：Heterotrophic nitrification (HN) and autotrophic nitrification (AN) are the two known pathways involved in aerobic biological ammonia removal. Ammonia, a common substrate, is used by the two bacterial functional groups. However, the key factors involved in the competition and succession of HN bacteria (HNB) and AN bacteria (ANB) remain largely unknown. In this study, alkalinity was found as a key parameter influencing the microbial communities involved in aerobic ammonia removal. When a stepwise decrease in alkalinity occurred, HN was significantly enhanced with increasing contribution to ammonia removal from 56.50 ± 4.02% to 96.00 ± 2.46%. The total relative abundance of HNB increased by 105.82%, while that of ANB decreased by 84.55%. With a stepwise increase in alkalinity, the contribution of AN to ammonia removal increased by 15.84 times, while the total relative abundance of HNB decreased by 70.52%. Alkalinity induced alterations in pH and free ammonia (FA), resulting in the generation of reactive oxygen species, increasing by 216.67 ± 19.95% (200 mg/L alkalinity) and 132.15 ± 16.38% (800 mg/L alkalinity). The succession of HNB and ANB was regulated by alkalinity, pH and FA influenced by alkalinity, with pH being the most influential factor (contributing 40%). This study elucidated a potential strategy for regulating the competition between ANB and HNB, offering strategic basics into achieving more efficient heterotrophic nitrogen removal in engineered wastewater treatment systems.
