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.

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.

Study of Ammonia and Humidity Sensor Based on Conductive Polymers and Its Composites [PDF]

open access: yes, 2016
环境中的气体和湿度条件会影响人们的生活和工业生产,因而需要研制响应灵敏度高、可靠性优异、长期稳定性好的气体和湿度传感器来进行检测。目前的气体和湿度传感器主要是以金属氧化物和有机高分子为敏感材料。然而基于金属氧化物的传感器工作温度高,基于有机材料的传感器稳定性较差,均无法满足低功耗、低维护成本传感系统的要求。因此本文通过具有p-n异质结的金属氧化物/交联导电聚合物复合材料作为室温气体传感器的敏感材料提高其传感性能;另外以新型的聚电解质--绿色无污染的聚离子液体--为湿度传感器的敏感材料,制得了全湿度范围 ...

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.

Engaging youth in biodiversity education through visual narrative

open access: yesConservation Biology, Volume 38, Issue 6, December 2024.
Abstract Engaging youth in early and sustained conservation education has important implications for promoting positive attitudes and behaviors in those who will become the future of conservation and management. Toward this goal, visual narratives (comic books, graphic novels) are an increasingly popular method used by conservation scientists to ...

小扭口藓(Barbula indica)芽胞发育特征的实验研究 [PDF]

open access: yes, 2005
在光照培养箱中人工对照培养小扭口藓(Barbulaindica(Hook. )Spreng)的芽胞,显微镜下观察并记录其发育成配子体的全过程。结果表明:小扭口藓芽胞在3 ~4d即可萌发; 10d左右开始分化出绿丝体、轴丝体及假根; 18d,轴丝体上的侧枝顶端细胞以分生缢割的方式产生单细胞或多细胞芽胞; 40d,轴丝体上开始出现配子体原始细胞;之后,配子体原始细胞发育成桑椹状的幼小配子体。还对芽胞形态发育、生理生态及配子体发生过程的特点进行了分析和讨论。,CN 23-1480/

The enigmatic life history of the bamboo explained as a strategy to arrest succession

open access: yesEcological Monographs, Volume 94, Issue 4, November 2024.
Abstract Bamboos are perennial woody grasses that display an enigmatic mix of traits. Bamboo is highly shade intolerant like early‐successional trees. Without secondary xylem, bamboos cannot continue to grow once they reach a maximum height or replace xylem damaged by hydraulic stress and must instead replace each stem after a few years using ...
