Integrative 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.

Gaoya dianqi, 2018 开关柜内部产生凝露时,会使零部件腐蚀和电气设备绝缘性能下降,引发设备绝缘闪络等。针对上述现象,在人工环境气候室内搭建了开关柜凝露观测系统,记录了开关柜内不同温湿度条件下凝露形成时间。结果表明:凝露形成时间是由柜内温度和相对湿度共同决定的,柜内温度越高、相对湿度越大,凝露形成时间越短。文中分析了含湿量与温度和相对湿度的关系,得出含湿量随温度和相对湿度的升高而增大,从理论上解释了凝露形成时间与温湿度之间的关系,证明了试验结果的准确性。

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

A dry eye model of C57BL/6 mouse induced by the topical application of benzalkonium chloride [PDF]
, 2016 目的：探究苯扎氯铵诱导C57BL/6小鼠干眼模型的最佳浓度，与局部应用苯扎氯铵对结膜及颈部淋巴结中炎症因子表达水平的影响。 方法：将60只小鼠分为6组，每组10只小鼠，在小鼠双眼结膜囊内滴入5μl不同浓度的苯扎氯铵（Benzalkoniumchloride，BAC）溶液（浓度分别为0.05%、0.075%、0.10%、0.15%、0.20%、0.25%），每天2次(9am，9pm)，持续7天，诱导小鼠干眼模型，另10只小鼠作为正常对照组，实验过程中，所有小鼠均置于正常环境条件下（即温度23±1 ...

Engaging youth in biodiversity education through visual narrative
Conservation 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 ...

Gaoya dianqi, 2018 户外设备长期工作在高温高湿、低温高湿等情况下,极易形成凝露,危害电路设备的正常运行。针对上述现象,文中在人工环境气候室内搭建了真型开关柜凝露试验系统,记录了不同温差及相对湿度条件下凝露形成时间,并测量了未形成凝露时的柜体内壁温度。结果表明:凝露形成时间是由温差和相对湿度共同影响的,当相对湿度不变时,温差越大,凝露形成时间越短;而当温差不变时,相对湿度越高,凝露形成时间也越短;并且,形成凝露的露点温度始终高于物体表面温度。最后,提出可通过减小温差 ...

Prediction of heterogeneous nucleation condensation effect on the surface of respiratory coal dust and test of dust reduction test [PDF]
Surface wettability of coal dust particles is an important factor restricting the efficiency of wet dust removal. Heterogeneous nucleation condensation on the surface of coal dust particles is a means without any pollution, without considering the ...

Study on Desiccant Nanofibrous Membranes based on Composite Polyvinyl Alcohol/Sodium Polyacrylate [PDF]
, 2019 A new type of composite polyvinyl alcohol/sodium polyacrylate (PVA-PAAS) nanofibrous membranes (NFMs) was prepared using the electrospinning method. The adsorption and desorption performance of these materials was compared with the PVA-PAAS solution ...

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

Functional Ecology, Volume 38, Issue 11, Page 2433-2446, November 2024.Read the free Plain Language Summary for this article on the Journal blog. Abstract Plant phosphorus (P) acquisition strategy is considered to be an intrinsic driver behind plant succession. However, variations in plant P acquisition strategies in connection to soil P fraction changes after wetland drainage remain unclear.
