野生动物学报, 2022 动物行为是动物对外界环境变化和内在生理活动改变所做出的整体性反应，动物行为节律研究是了解其活动特征时空变化及影响因素的重要内容。因此，于2017年3月—2018年12月采用红外相机监测技术，在药山国家级自然保护区布设了45台红外相机对中华斑羚（Naemorhedus griseus）的日活动节律进行研究。结果表明：中华斑羚的活动具有明显的晨昏性，活动模式呈经典的双峰型，上午的活动高峰出现在06：00—09：00，活动的最高峰出现在09：00，下午的活动高峰出现在16：00—20：00 ...

Habitat and spatial trends of U.K. wintering waterbird populations over 50 years
Conservation Biology, EarlyView.Abstract The United Kingdom is an important wintering ground for millions of waterbirds. Most U.K. wintering waterbird populations increased between 1970 and the mid‐1990s, but declined thereafter. We examined U.K. population indices in 46 wintering waterbird species in two 25‐year periods, 1970–1994 and 1995–2019, to identify which waterbird groups ...

浙江九龙山国家级自然保护区黑麂日活动节律和垂直迁移的季节变化
野生动物学报, 2023 为准确全面地了解黑麂（Muntiacus crinifrons）在九龙山国家级自然保护区的日活动节律和某些栖息地生态因子选择的季节性规律，于2017年10月—2021年2月，在九龙山国家级自然保护区采用红外相机法对黑麂日活动节律和垂直迁移的季节变化进行研究。研究期间，共拍摄到352张黑麂照片，提取到243次有效探测。结果显示：黑麂是晨昏双峰型的昼行性动物。通过四季对比发现，黑麂夏季的活动强度比春季、秋季和冬季高，而各季节间的日活动高峰期时间段和数量存在差异。黑麂 偏好栖息于坡度为20°~40 ...

International Journal of Applied Linguistics, EarlyView.ABSTRACT Translating local research into English as a lingua franca (ELF) connects local scholarship with global readership, but this process remains constrained by language barriers. Large language models (LLMs) offer advanced accessible solutions, but their responsible integration into academic translation requires a deeper understanding of the ...

Policy Studies Journal, Volume 54, Issue 3, August 2026.ABSTRACT Disruptive innovations often diffuse faster than inherited policy institutions can classify, assign jurisdiction, and govern them. In these early phases, the central struggle is often not yet about the stringency of substantive standards, but about prior questions of what the innovation is (its legal and administrative classification), who is ...

Integrative Conservation, Volume 5, Issue 1, Page 125-136, March 2026.We collated detections of the sun bear from new and previously published camera trap studies across its range. We then analysed these detections at two different spatial scales to assess the habitat associations and diel activity of this species. We found that the sun bear is tolerant to moderate habitat disturbances. ABSTRACT Degraded tropical forests,

Journal of Critical Infrastructure Policy, Volume 7, Issue 1, Spring/Summer 2026.ABSTRACT Time and chronology form the invisible architecture upon which modern civilization depends, governing synchronization across markets, power grids, communication networks, transportation, and defense. Yet, this shared temporal framework, engineered through atomic clocks, satellites, and digital synchronization, faces growing vulnerabilities ...

International Journal of Urban and Regional Research, Volume 50, Issue 1, Page 191-220, January 2026.Abstract Henry George advocated for capturing land value increases for public ends. The active approach of public authorities organizing and financing land development can help capture higher land value increases, as Hartman and Spit indicate. However, this approach hardly happens in developing countries, where the coalition of private developers and ...
