The inhibition of the POD-like activity of the nanozyme by tetracycline (TC) facilitated the development of a colorimetric and visual dual-modal detection system for TC, with detection limits of 0.015 mg/L and 0.12 mg/L, respectively. Furthermore, the nanozyme exhibited a porous structure similar to that of ZIF-8, with a specific surface area and pore diameter measured at 927.4 m<sup>2</sup>/g and 5.7 nm, respectively, resulting in an impressive adsorption capacity for TC of 1625.35 mg/g. Additionally, the band gap value of 4.16 eV indicates a strong photocatalytic oxidizing ability, enabling nearly complete degradation of the remaining TC after adsorption.

Under the APV, soil temperature increased. During seedling, oilseed rape adopted a resource-acquisition strategy to improve its growth and photosynthetic rates by reducing specific root length (SRL) and root tissue density (RTD), and increasing leaf chlorophyll content. The APV also promoted nutrient accumulation by increasing root soluble sugars and upregulating organic acid metabolites, while downregulating defense-related metabolites such as phenylpropanoids, thereby promoting growth during the blooming stage. During blooming, shading by the APV caused plants to switch to a resource-conservation strategy by increasing LMA, RTD, and chlorophyll content, reducing SRL, and improving resource-utilization efficiency. Plants shifted resources from growth inputs to starch storage in leaves and upregulated leaf lipid metabolism to increase yield. The changes in growth and defense strategies were regulated by hormones such as abscisic and indoleacetic acids.

Existing thinking around the required duration of monitoring is dominated by the perceived importance of long-term datasets. However, how long do we need to monitor to fill a knowledge gap? We use existing data on spawning of a native fish in the Goulburn River, south-east Australia, an existing flow-ecology model, and three techniques: (i) historical data evaluation (ii) bootstrapping analysis and (iii) synthetic data simulation, to examine the contribution of additional data to reducing model uncertainty. Results from the observed monitoring data appear to suggest that 4 years of data (2014-2017) is adequate, and that additional data provides limited additional understanding of the relationship between discharge and spawning. However, this result was contingent upon the particular sequence of 4 years of data that was observed. Bootstrapping the same dataset and simulating data both suggest 8 years might be necessary. With the case-study program having now collected 10 years of monitoring data, we contend that monitoring could be scaled back, with resources freed up shifting to addressing other knowledge gaps. This case study demonstrates that, when it comes to filling specific knowledge gaps, long-term data sets from monitoring are not always required, potentially allowing managers to reallocate monitoring effort to other areas of higher uncertainty. While different managers may draw this line at different points, using resampled or synthetic monitoring data to demonstrate the value of monitoring is a method that can be applied to other endpoints and other monitoring programs.

In this study we evaluate how trade-offs between timber yield and habitat availability vary across species with different habitat needs and spatial scales. We simulated and optimized three boreal Finnish production landscapes spanning a gradient of management intensities using the MELA2.0 forest simulation package.

However, the factors influencing youth environmental actions have not been fully validated, and the role of national-level influences is often overlooked. This study aims to identify the factors that are associated with adolescents' public-sphere and private-sphere environmental actions. Unlike prior studies, which typically use single-level analyses, we simultaneously examine individual, school, and national factors to capture the often-overlooked national context. Using PISA-2018 data on 420,339 adolescents from 66 countries, we used LightGBM and XGBoost to build predictive models. Shapley Additive Explanations (SHAP) were then applied to detect non-linear threshold effects and to quantify each feature's contribution to environmental action. Results indicate that individual-level factors, such as environmental attitudes, the discussion of international events in school, and critical thinking, are significantly associated with adolescents' private-sphere environmental actions. Conversely, national-level factors, such as Sustainable Development Goal (SDG) performance and country vulnerability, play a particularly strong role in shaping public-sphere environmental actions. This study underscores the importance of incorporating national-level factors, which have often been under-emphasized in research on youth environmental behavior.</p>","PeriodicalId":356,"journal":{"name":"Journal of Environmental Management","volume":"390 ","pages":"126398"},"PeriodicalIF":8.0,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144525834","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}
