Sprouting responses were assessed at three post-fire intervals (2, 4, and 10 years), focusing on sprout origin (root vs. stump), sprout density, and growth performance of sprouts (height and diameter). The effects of stump diameter and species-specific traits on resprouting capacity were also evaluated. Findings revealed that root suckering was the predominant regeneration mechanism, contributing more than 90% of sprouts across all stands. Sprouting capacity remained relatively stable among different post-fire ages and oak species, showing no significant differences. In contrast, a strong negative relationship was observed between stump diameter and both sprout density and growth, with small to medium-sized stumps (5–35 cm) supporting the highest regeneration potential. Annual diameter and height increments were greatest in the early post-fire years (11.2 mm and 63.1 cm yr⁻¹ in 2AF stands) but declined significantly with stand age and increasing stump size, reflecting self-thinning and resource limitations. The largely uniform sprouting response across species highlights shared adaptive mechanisms such as persistent bud banks and robust root systems. Overall, the study demonstrates that root-derived vegetative sprouting—particularly from small to medium-sized stumps—constitutes the primary recovery pathway in fire-affected Zagros oaks, ensuring resilience where seed-based regeneration is limited. These findings emphasize the ecological importance of vegetative regeneration under recurrent disturbances and provide a basis for guiding post-fire management and restoration strategies in oak-dominated ecosystems. While these findings provide valuable baseline insights for guiding future forest restoration and management in fire-prone landscapes, their applicability remains geographically restricted to the Zagros region. Long-term monitoring will therefore be necessary to fully evaluate the success and persistence of post-fire regeneration dynamics.</p></div>","PeriodicalId":544,"journal":{"name":"Environmental Monitoring and Assessment","volume":"197 11","pages":""},"PeriodicalIF":3.0,"publicationDate":"2025-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145249214","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}

A total of 9,270 topsoil samples (0–15 cm) were collected from rice fields in all 25 districts using a stratified random sampling method, covering both CKDu-affected and non-affected regions. Classification of these zones was based on CKDu intensity as defined by Ranasinghe et al. (2019). Exchangeable As, Cd, and Pb were extracted using 0.01 M CaCl₂ and quantified via inductively coupled plasma mass spectrometry (ICP-MS). Soil pH and electrical conductivity (EC) were analyzed using a 1:5 soil-to-water ratio. Statistical analyses were conducted to compare exchangeable trace element levels, pH, and EC between areas with different CKDu intensities. Results showed no significant differences (P &gt; 0.05) in exchangeable As and Cd concentrations between affected and unaffected regions, while Pb levels were significantly higher (P &lt; 0.05) in non-CKDu areas. Additionally, CKDu prevalence was higher in Alfisol-dominant regions, and lowest in areas dominated by Inceptisols, Entisols, Histosols, Ultisols, and Vertisols.

Persistent pollutants, including microplastics, heavy metals, and synthetic pesticides, pose significant threats to environmental sustainability due to their resistance to natural degradation and their adverse effects on ecosystems and human health. Through the qualitative synthesis of over 50 recent peer-reviewed studies, this review highlights notable AI-driven developments representing substantial innovations in environmental biotechnology. Enhanced detection capabilities are demonstrated by AI models, which achieve exceptional detection accuracies exceeding 90% for microplastic classification, enabling precise ecological monitoring that was previously difficult with traditional methods. Compared with conventional methods, advanced enzyme engineering is exemplified by the AI-enabled design of engineered enzymes that increase the degradation rates of polyethylene terephthalate (PET) polymers by up to 46-fold, representing a significant increase in bioremediation technology. Innovative predictive frameworks emerge from AI integration, accelerating the design of microbial enzymes and predicting pollutant behaviors with remarkable accuracy, providing a novel framework for pollution control that is not achievable through conventional approaches. This study demonstrates substantial improvements in the accuracy and efficiency of identifying and monitoring environmental pollutants, enabling more precise assessment and proactive management strategies. The strategic integration of AI in environmental applications has accelerated microbial enzyme design, enhanced ecological risk assessments, and provided innovative solutions for addressing persistent pollution challenges. The findings of this review emphasize AI’s crucial and creative role of AI in environmental biotechnology, offering valuable insights for developing sustainable remediation strategies to combat persistent pollutants and protect ecosystem health.</p></div>","PeriodicalId":544,"journal":{"name":"Environmental Monitoring and Assessment","volume":"197 11","pages":""},"PeriodicalIF":3.0,"publicationDate":"2025-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145237535","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}

To this end, this study proposes a novel transition-level analytical framework—the Land Transition Intensity Spectrum (LTIS). The LTIS integrates absolute and relative transition intensities, gain and loss directions, and multiple temporal intervals. Through a quantitative approach, it identifies transitions that, across multiple periods, stably exhibit targeted tendencies in both absolute magnitude and relative proportion for the initial and final land use and land cover (LULC) classes. These transitions strongly affect the compositional structure of land use and should be prioritized in monitoring and governance. The LTIS was applied to LULC data from seven representative countries between 2000 and 2020, focusing on transitions among six major land classes to evaluate its utility. The results reveal that the LTIS effectively uncovers shared and divergent LULCC patterns across countries. Overall, the LTIS extends the analytical depth of conventional intensity analysis by integrating absolute and relative perspectives while enhancing the visualization and interpretability of land-use transitions.</p></div>","PeriodicalId":544,"journal":{"name":"Environmental Monitoring and Assessment","volume":"197 11","pages":""},"PeriodicalIF":3.0,"publicationDate":"2025-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145237590","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}
