Functional Ecology, Volume 39, Issue 12, Page 3504-3516, December 2025.Read the free Plain Language Summary for this article on the Journal blog. Abstract Nitrogen (N) deposition strongly affects litter decomposition and nutrient release, thereby reshaping carbon cycling in terrestrial ecosystems. Although most studies have focused on above‐ground litter, the effects of N addition on fine root decomposition and their ...

Integrative Conservation, Volume 4, Issue 3, Page 464-475, September 2025.This study investigates the diversity, conservation status, distribution, and discovery rate of 84 Cyrtodactylus species in Indochina. Despite rising discovery rates, many species are unassessed, with over half unprotected and 90.5% endemic. This study suggests expanding protected areas and implementing an integrated approach to conservation with IUCN ...

Implications of Tobacco Use on Pathogen‐Driven Diseases: A Public Health and Policy Perspective
World Medical &Health Policy, Volume 17, Issue 3, Page 468-474, September 2025.ABSTRACT The tobacco epidemic remains one of the most significant global public health challenges, responsible for over 8 million deaths annually, with a substantial portion occurring among non‐smokers exposed to second‐hand smoke. While cigarette smoking remains the most prevalent form of tobacco use worldwide, the rise of electronic nicotine delivery

Laser‐guided thin‐film self‐rolling for asymmetric small‐scale swimmers
Rare Metals, Volume 44, Issue 8, Page 5607-5620, August 2025.Graphical abstract AbstractSmall‐scale robots are promising miniaturized devices in biomedicine. Thin‐film self‐assembly is a commonly used strategy to fabricate tubular small‐scale robots. However, the existing methods have limitations like complex manufacturing processes and limited control of self‐assembly behavior.

Shuitu Baochi Xuebao, 2003 用土壤微形态的研究方法观察了分析了黄河三角洲土壤的微观特征，用以研究土壤的抗蚀性，研究结果表明该区土壤发育处于初始阶段，土壤在矿物成分，有机物质，土壤形成物等方面仍然在很大程度上保留着冲积物的特征，土壤微结构差，抗蚀性弱，微生态系统脆弱，土壤经人为扰动后易发生水土流失，由三角洲顶部向河口地区。土壤发育愈来愈差，也愈容易遭受侵蚀，因而土地开发利用中，必须重视对土壤微生态环境的保护。

Dizhen xuebao针对2023年12月18日甘肃积石山MS6.2地震，基于AMSR2微波亮温数据，使用基于小波分析的两步差法提取了地震前的微波亮温异常，对震前异常的时间、空间和强度演化特征进行了总结分析，并探讨了微波异常的产生机理。结果显示：空间上，震前微波异常呈高温条带与低温区域相间的“// ”形分布格局；时间上，两高温条带的微波异常在达到峰值后大幅度降低，存在震前平静期。此外，积石山地震微波异常的空间分布格局与岩石加载热红外观测实验结果具有一定的相似性，可能表征了地震前地壳岩体内微破裂的大规模发育。进一步结合遥感 ...

Journal of Linguistic Anthropology, Volume 35, Issue 2, August 2025.Abstract This article argues that social actors' media ideologies about digital interfaces are key to the enregisterment of online activities. Focusing on an online register emergent from user activities around Year, Hare, Affair (YHA)—a state‐aligned Chinese animation—I explore how different metadiscourses evaluate this register by entextualizing ...

考虑高原山区复杂微地形影响下输电线路雷击跳闸率的大数据修正方法研究
Dianci bileiqi微地形因素对输电线路杆塔雷击故障有重要影响，然而微地形影响线路雷击跳闸率机理复杂，现有雷击跳闸率计算方法的结果与实际值差距较大，目前研究仍缺乏准确量化微地形影响的计算方法。故本研究通过地理信息软件和地表流水物理模拟分析法完成了云南高原山地地区输电线路杆塔的微地形自动识别和提取，并与人工观察对比，验证了文中自动提取微地形模型的准确性。进而，建立了高原山地地区的雷击跳闸率历史值、雷击跳闸率的计算仿真值、5种杆塔结构参数以及6种微地形（海拔、坡度、坡向、地表覆盖类型、水域密度以及地形 ...
