Conservation Biology, Volume 40, Issue 1, February 2026.Abstract Urgency to save species from extinction has prompted increased investment in law enforcement in protected areas. To date, such law enforcement has largely focused on increasing costs and reducing opportunities for offending. However, these resource‐intensive approaches are not always effective and can contribute to conflict between people and ...

Evolution of research on global amphibian declines
Conservation Biology, Volume 40, Issue 1, February 2026.Abstract In the late 1980s, the scientific community became aware of severe, enigmatic amphibian population declines. These declines triggered a wave of research focused on quantifying their extent and identifying key drivers. We used text‐analysis techniques, including topic modeling and geoparsing, to examine the evolution of research focused on ...

Gaoya dianqi, 2018 电力设备中,不同类型的放电因放电功率、能量的差异对设备绝缘的损害能力存在差异,即对绝缘的危害程度不同,确定局部放电类型是放电危险度评估的基础。文中对典型缺陷条件下的局部放电谱图提取了基本参量及统计参量等多种特征指纹;为了降低识别参量的维度,定义了特征向量可分性评估准则,并使用浮动前向搜索算法选取了可分性最优的9组特征参量;分别使用主成分分析、线性可分性分析、核主成分分析及通用可分性分析4种方法将特征向量降为2维,结果表明,使用通用可分性分析降维后特征参量可分性最优。之后,提出了多算法联合的模式识别分类器,

Weaving knowledges to support wildlife health surveillance in Kenya's pastoral rangelands
Conservation Biology, Volume 40, Issue 1, February 2026.Abstract In wildlife–livestock–human interfaces, pathogens capable of spreading between wild and domestic animals and humans have important implications for conservation outcomes, economics, and public health. Robust wildlife health surveillance can help address these risks.

An empirical analysis of the factors affecting the real estate price in Hangzhou City [PDF]
, 2016 近几年来我国大部分城市房价快速上涨，高昂的房价与相对较低的收入已 成为我国居民日常生活中一个重要的矛盾。但自从14年下旬开始，全国房价开 始呈现分区域的差异化趋势，二三线城市房地产价格出现不同程度的下滑，而 一线城市房价依然坚挺。从宏观角度来看，房价是关乎社会稳定的一个重要因 素；从微观角度来看，房价对人民的日常生活有着巨大的影响。所以，房地产 价格不仅成为专家学者的重要研究课题，也成为政府、企业和媒体关注的重 点。但是，此前关于房地产价格的影响因素研究一直面临着许多困境，我国政 ...
