Impacts of Human Development on Wildlife Use of Corridors in Botswana 人类开发对博茨瓦纳野生动物廊道利用的影响
Integrative Conservation, Volume 5, Issue 1, Page 164-171, March 2026.This study examined the effect of landscape‐scale human impact on wildlife in Botswana. We examined how species use wildlife corridors in two different human‐dominated landscapes. We identified differences in temporal overlap between wildlife and humans across both landscapes, which is fundamental to consider in both current and future conservation ...

Conservation Biology, Volume 40, Issue 1, February 2026.Abstract As the global protected area (PA) network expands to meet international targets, it is important to assess whether traditional reliance on public land will suffice for projected PA growth or whether other tenures, such as Indigenous or pastoral lands, may increasingly contribute.

Finding floral and faunal species richness optima among active fire regimes
Conservation Biology, Volume 39, Issue 6, December 2025.Abstract Changing fire regimes have important implications for biodiversity and challenge traditional conservation approaches that rely on historical conditions as proxies for ecological integrity. This historical‐centric approach becomes increasingly tenuous under climate change, necessitating direct tests of environmental impacts on biodiversity.

Zhongguo shiyan zhenduanxue, 2012 目的探讨COMT基因Met多态与子宫内膜异位症的关系。方法采用蛋白酶K消化-饱和酚氯仿法提取外周血白细胞基因组DNA,聚合酶链式反应-限制性片段长度多态性（PCR-RFLP）方法分别对120例子宫内膜异位症患者（内异症组,含59例腺肌病患者）和65例非内异症及腺肌病女性（对照组）进行COMT基因分型。结果 （1）内异症组和对照组G/G、G/A和A/A基因型频率分别为17.5%、43.3%和39.2%,9.2%、50.8%和40.0%,差异无统计学意义;内异症组和对照组A等位基因频率分别为27.1%和29.

Role of low‐impact‐factor journals in conservation implementation
Conservation Biology, Volume 39, Issue 2, April 2025.Abstract Academic review, promotion, and tenure processes place a premium on frequent publication in high‐impact factor (IF) journals. However, conservation often relies on species‐specific information that is unlikely to have the broad appeal needed for high‐IF journals.

Gaoya dianqi, 2019 文中提出了一种气体绝缘组合电器（gas insulated switchgear,GIS）超声波检测异常信号的时频特征计算与诊断方法。首先运用希尔伯特—黄变换（Hilbert-Huang transform,HHT）得到描述超声波信号包络线的时频特征的Hilbert幅值谱。在此基础上,给出了离散条件下Hilbert边际谱与平稳性指数的计算方法,分别表示信号中各频率成分的总强度和平稳性。然后将Hilbert边际谱与平稳性指数结合起来分析,可以直观读取信号的时频特征,进而推断出异常气室的故障原因 ...

Gaoya dianqi, 2020 随着GIS电压等级的升高及应用的普及,现场出现了越来越多的GIS异响振动问题。GIS现场的异响振动有装配不良造成的、也有高频信号入侵引起的,甚至存在随GIS运行方式的不同出现时强时弱的异响振动问题。文中旨在对时强时弱异响振动的成因进行剖析,以从源头上解决防振问题。从理论上分析了空载及负载时GIS导体与壳体间存在的电场力和电磁力,推导出电场力、电磁力与施加电压值、承载电流值及工频频率间的数学表达式。GIS空载运行时导体与壳体间仅有电场力的作用、且电压等级越高电场力越大 ...
