China's Eco‐Civilisation, Climate Leviathan, and Hobbesian Energy Transition

open access: yesAntipode, Volume 57, Issue 3, Page 830-861, May 2025.
Abstract Scholars have hitherto tended to theorise China's ecological civilisation project either as a form of environmental authoritarianism or as a vision of eco‐socialism. This paper contributes to the conversation by conducting a textual analysis of Chinese scholarly discussions on eco‐civilisation.

广东大瑶山省级自然保护区小麂和野猪活动节律和重叠度研究

open access: yes野生动物学报
野生动物的活动节律和重叠度研究对于制定有效的保护和管理策略至关重要。为掌握小麂(Muntiacus reevesi)和野猪(Sus srofa)的活动节律和重叠度,2020年7月—2022年6月,利用红外相机技术对广东大瑶山省级自然保护区的小麂和野猪进行研究,应用核密度估计、重叠指数及拍摄率等研究小麂和野猪的日活动节律、季节性变化规律和不同林分类型的活动规律。结果表明:小麂属于典型的晨昏性动物双峰型,活动高峰06:00—08:00和18:00—20:00,日活动模式比较稳定,不会随季节改变而明显波动 ...

人工圈养紫貂(Martes zibellina)行为谱构建及行为节律研究

open access: yes野生动物学报, 2015
2014年5月~2015年2月,采用全事件取样法和扫描取样法(scan sampling method)对人工圈养的8只紫貂进行行为学观察,定义了休息、运动、采食、排泄、警戒以及其他行为等行为谱。通过对雌雄紫貂在不同季节行为节律研究发现:除了睡眠行为、卧息行为和玩耍行为外,其他行为在时间分配上均表现出雄性高于雌性,卧息行为和其他行为时间分配雌雄之间差异性显著 ...

Enlisting toddler cooperation through structure and autonomy support: The amplifying role of suboptimal relationship mutuality

open access: yesInfant Mental Health Journal: Infancy and Early Childhood, Volume 45, Issue 6, Page 670-682, November 2024.
Abstract Regular repair of normative mother‐toddler conflict is required for relational health; yet, we still need improved delineation of regulation strategies that can promote child cooperation. Contemporary conceptualizations of positive parenting propose that structure and autonomy support each facilitate children's optimal engagement; however ...

小熊猫在云岭山脉南部地区的活动节律初步研究

open access: yes野生动物学报, 2022
2019年10月—2021年5月,在云岭山脉南部地区采用红外相机法和样线法对小熊猫(Ailurus fulgens)的分布和活动节律进行研究,共收集到29个分布位点和94张小熊猫独立有效照片。小熊猫分布于大理市、漾濞县、剑川县、兰坪县和玉龙县,海拔3 000~4 000 m为优势分布区,林下有竹的常绿阔叶林、常绿和落叶阔叶林为优势分布生境。小熊猫全年的日活动节律呈现单峰型,高峰为01:00—03:00,低谷为18:00—20:00,四季对比发现冬季的活动强度比春、夏、秋季高,日活动节律在雨季 ...

Change in cyclone disaster vulnerability and response in coastal Bangladesh

open access: yesDisasters, Volume 48, Issue 2, April 2024.
The number of deaths owing to tropical cyclones in Bangladesh has significantly reduced. Category 4 Cyclone Gorky in 1991 and Sidr in 2007 caused 147,000 and 4,500 deaths respectively, whereas Category 1 Cyclone Mora in 2017 resulted in six. Face‐to‐face interviews with 362 residents, participant observation, and focus‐group discussions answer a ...

圈养雄性成年棕熊越冬行为的观察

open access: yes野生动物学报, 1997
本文采用扫描取样法和随意取样法,对饲养条件下两头雄性成年棕熊的越冬行为和活动节律等进行了观察。结果表明活动和摄食行为主要集中于早3:00~20:55,在此期间主要行为是休息(79.1%)和活动(12.5%)。卧睡是休息的主要类型,站立是活动的主要类型,而卧吃又是摄食的主要类型。活动节律有三个频率高峰(41.7、34.7、34.0),摄食节律也有三个高峰(34.0、25.8、18.1)。两种节律有明显的相关性。给食是激起活动和摄食的主要因子。凡种主要行为相互间隔出现。

佛坪国家级自然保护区大熊猫与潜在捕食者的时空动态

open access: yes野生动物学报, 2022
了解同域分布物种的行为活动在空间和时间上的分化,从群体行为上判断其生态位分化,是揭示其共存机制的重要途径。为了探明秦岭大熊猫(Ailuropoda melanoleuca)与同域分布的金钱豹(Panthera pardus)、黄喉貂(Martes flavigula)和豹猫(Prionailurus bengalensis)3种潜在捕食者的日活动节律、时空生态位及共存机制,于2017年1月—2019年12月在陕西佛坪国家级自然保护区利用红外相机技术开展监测。相关监测数据采用核密度估计 ...

Endangered beach mouse resistance to a Category 5 hurricane is mediated by elevation and dune habitat 濒危海滩鼠类五级飓风的抵抗力受海拔和沙丘栖息地的调节

open access: yesIntegrative Conservation, Volume 3, Issue 1, Page 36-45, March 2024.
Threatened and endangered species that occur in coastal areas are susceptible to the impacts of hurricanes that can destroy and reorganize their habitats. We used long‐term tracking of endangered beach mice to reveal they survive these impacts by using high elevation dune habitats to stay safe.
