Identifying potentially suitable and accessible refugia to mitigate impacts of an emerging disease on a rare tree

open access: yesConservation Biology, Volume 39, Issue 6, December 2025.
Abstract Identifying refugia from emerging threats is vital to ensure the persistence of rare and threatened species, but modeling habitat distribution for these species is challenging and the role of people in refuge management is rarely considered. Myrtle rust is an emerging infectious disease that represents a grave threat to the rare wetland tree ...

Spatial Phylogenetic Analysis of Chinese Lizards: Insights Into Ecological Drivers and Conservation Gaps 中国蜥蜴系统发育的空间分析:生态驱动因素与保护空缺

open access: yesIntegrative Conservation, Volume 4, Issue 3, Page 430-441, September 2025.
Our study identifies southern China, including mountainous regions and islands, as key areas rich in phylogenetic diversity, and phylogenetic endemism of lizards that are currently under‐protected. Current protected areas however do not adequately cover regions that are critical for preserving the evolutionary history of lizards.

Agricultural Lands as Important Wintering Habitats for the Critically Endangered Yellow‐Breasted Bunting in Nepal 尼泊尔农业用地作为极危黄胸鹀的重要越冬栖息地

open access: yesIntegrative Conservation, Volume 4, Issue 2, Page 134-142, June 2025.
Our study addresses the significant knowledge gap regarding the wintering population and habitat utilization of the Yellow‐breasted Bunting (Emberiza aureola) in Nepal, providing crucial insights that can aid in the conservation of this critically endangered species in wintering grounds.

微纳结构表面上润湿动力学的跨尺度研究

open access: yes, 2012
微纳结构表面通过固体表面的拓扑特性,在原子尺度、微观尺度到宏观尺度上都影响和控制液体在固体表面润湿的平衡状态和动态过程,改变固体表面的润湿性能。本文通过跨尺度实验研究、数值模拟和理论建模相互结合、相互补充的研究方法,对微纳结构亲液表面上的动态润湿行为展开系统、深入的研究,定量化地探索微纳结构的润湿性能、拓扑特性、界面张力等性质对于液体润湿行为的影响。我们发现微纳结构亲液表面虽然提供更多的驱动力,也将液体钉扎在微纳结构周围,二者达到动态平衡。由于固液相互作用和表面粗糙的影响 ...

高海拔外绝缘研究中的湿度问题

open access: yesGaoya dianqi, 1987
本文详细论述了空气的水汽部分压力、绝对湿度、相对湿度和比湿之间的关系,以澄清在高海拔外绝缘研究中在选用湿度参效上的模糊概念及错误。本文还给出了在非标准大气压力下计算湿度参数的湿度图,建议取代IEC标准和国标GB311类似的用干泡和湿泡温度计算绝对湿度图。

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.

增塑剂对坯料性能的影响

open access: yesDianci bileiqi, 2006
测试了添加两种不同粘度增塑剂对坯料泥浆性能、吸湿性能及其它性能的影响,结果表明,在相对湿度较低的条件下,高粘度增塑剂(干料0.8%的含量)的加入对坯料的吸湿性能有影响;在相对湿度较高的条件下,高、低粘度增塑剂(干料0.8%的含量)的加入对坯料的吸湿性能均有影响,且高粘度增塑剂的影响较明显。两种增塑剂对坯料其它性能的影响基本相同。建议增塑剂的加入量应结合坯料中粘土的可塑性能而定,当坯料中粘土的可塑性能满足生产工艺条件时,可以适当减少增塑剂的加入量。

Using life history traits to assess climate change vulnerability in understudied species 利用生活史特征评估研究不足物种的气候变化脆弱性

open access: yesIntegrative Conservation, Volume 3, Issue 4, Page 368-381, December 2024.
Lack of species information complicates understanding climate change vulnerability, but life history traits can be proxies for missing information. In the north‐central United States, useful traits for discriminating vulnerability of amphibians include range size, clutch size, diel activity patterns, and habitat breadth.

夏季晴天沼泽湿地贴地气层气温和相对湿度日变化特征

open access: yes, 2009
2008年68月在洪河国家级自然保护区沼泽湿地015 m贴地气层内,进行了6个高度的气温和相对湿度的野外定位观测。根据实测数据,分析了夏季晴天沼泽湿地贴地气层的气温和相对湿度的日变化特征。结果表明,夏季晴天沼泽湿地贴地气层内,气温日变化曲线为单峰型曲线,各高度的日最高气温和日最低气温分别出现在14∶00和03∶00,日平均气温和气温日较差都随高度递减。气温廓线有夜间辐射型、早上过渡型、白天日射型及傍晚过渡型4种分布类型。夏季晴天,0.515 m的日平均气温直减率为0.10℃/m ...

Identification, spatial distribution, and associated factors of urban protected areas in China

open access: yesConservation Biology, Volume 38, Issue 6, December 2024.
Abstract The increasing proximity between protected areas (PAs) and urban areas, which can lead to urban protected areas (UPAs), is now commonplace. Use of Euclidean distance to measure the distance between PAs and cities has not correctly portrayed the spatial relationship between PAs and cities.
