野生动物学报, 2011 为了解散放情况下盘羊的昼间活动节律、时间分配规律及游人活动的影响,2009年5～6月,在新疆天山野生动物园用直接观察法对909头盘羊的昼间活动节律进行了观察。经过数据统计分析,结果表明:散放情况下盘羊夏季昼间活动规律性较强,从8:00～13:00活动频率较高,之后活动频率逐渐降低,在14:00～15:00降至最低值20%,后逐渐回升,至18:00活动频率达98%。在8:00～10:00和17:00～18:00采食频率较高;11:00～12:00警戒频率较高。昼间各类行为所占的时间比例从大至小为:采食41%

野生动物学报, 2022 为了解栖息地和气候变化对北树鼩（Tupaia belangeri）活动的影响，于2012年8月—2013年7月采用红外相机技术对广西弄岗国家级自然保护区15 hm2森林动态监测样地及其周边区域内的北树鼩进行监测，采用核密度估计、重叠指数及相对活动强度指数分析其日活动节律及季节性变化规律。结果表明：北树鼩的日活动节律模式属于晨昏活动类型（日活动高峰期：07：00—08：00、16：00—17：00）。不同月份间北树鼩的活动强度指数（t=13.072，df=11 ...

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 ...

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 ...

Behavioral interventions to reduce demand for threatened freshwater turtles as pets
Conservation Biology, EarlyView.Abstract Growing demand for freshwater turtles as pets has fueled illegal trade and accelerated wild population declines, underscoring the need for theory‐based demand‐reduction interventions. We conducted a three‐part randomized controlled trial with active turtle keepers (n = 1800) in China to test conservation‐ and legality‐framed messages by ...

Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT To overcome the strength–ductility trade‐off in fabricated Ti‐2Al‐2.5Zr alloy tubes, we systematically investigated the microstructural evolution and mechanical behavior throughout thermomechanical processing, including hot working (forging and extrusion) and cold multi‐pass rolling.

Risk, Hazards &Crisis in Public Policy, Volume 17, Issue 2, June 2026.ABSTRACT The article examines how ‘soft’ information functions in rational organisations that emphasise hard information, and how this affects safety. Drawing on fieldwork in a high‐security prison, we analyse how frontline personnel interpret soft information about potential disturbances. We identify three coexisting institutional logics shaping these

Biodiversity‐driven spatial conservation planning to delineate temporally stable regions
Conservation Biology, Volume 40, Issue 3, June 2026.Abstract The accelerating loss of biodiversity underscores the critical need for effective conservation strategies, particularly in the face of climate change and anthropogenic pressures. We devised a conservation planning framework that adopts a temporal stacking approach to species distribution models and landscape connectivity analyses. These models

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,

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Low conductivity, slow ion‐diffusion, and limited reactive sites are common problems in electrocatalysts and electrode materials. In this study, a complex NiTe–CoTe heterojunction with abundant Te vacancies embedded in N, P, and F co‐doped hollow carbon nanorods (NiTe1−x–CoTe1−x/NPFC) was fabricated via a simple ionic liquid‐assisted ...
