Lessons learned from screening potential other effective area‐based conservation measures
Conservation Biology, Volume 40, Issue 2, April 2026.Abstract Other effective area‐based conservation measures (OECMs) are sites that deliver effective biodiversity outcomes irrespective of their management objectives. These areas are widely expected to play an important role in efforts to protect 30% of Earth by 2030.

Gaoya dianqi, 2015 金属化膜电容器具有高储能密度、高可靠性和高寿命特点。自愈是导致电容器电容量下降的主要原因。笔者分析金属化膜的自愈特性和电容量下降机制,通过研究自愈过程中的自愈面积、自愈能量和击穿电压的关联性,得出电压幅值和电压反峰比对电容器的寿命影响程度并归纳出经验公式。通过对金属化膜电容器的寿命测试,对经验公式中的系数进行拟合。最后得出不同电压幅值和不同电压反峰比下电容器寿命经验型预测公式。

Conservation Biology, Volume 40, Issue 2, April 2026.Abstract Illegal wildlife trade (IWT) is one of the largest global illegal activities, and it negatively affects biodiversity and sustainable development worldwide. DNA barcoding coupled with high‐throughput sequencing (i.e., metabarcoding) is useful in identifying taxa affected by IWT and has been used routinely for decades.

How much biotic nativeness matters across human demographic groups
Conservation Biology, Volume 40, Issue 2, April 2026.Abstract Many central concepts of conservation biology—such as nativeness—are structured by ecological and social factors. However, the social consequences of using these concepts to make conservation decisions remain inadequately understood. Some researchers argue that nativeness, rather than acting as an objective proxy for important ecological ...

People and Nature, Volume 8, Issue 3, Page 741-753, March 2026.Abstract Currently, scholarship on education to foster connectedness with nature primarily focuses on children. As adults likewise face the disconnection from nature and play a key role in influencing children, it is important to understand how they perceive, engage in, and benefit from relevant programmes.
