Insights for conservation from the Ecological Knowledge Games project
Conservation Biology, EarlyView.Abstract Environmental conservation research requires robust methods for collecting large‐scale behavioral data and engaging diverse stakeholders in decision‐making processes. We (Y.P., A.B.D., and N.B.) created EcoKnowGames (Ecological Knowledge Games), a transdisciplinary project that develops knowledge games for conservation science and data ...

特约主编寄语 双碳驱动下气-固复合绝缘沿面放电特性与耐电性能提升新技术
Gaoya dianqi, 2023 气固绝缘系统广泛用于高电压装备,如气体绝缘开关设备、气体绝缘输电线路、开关柜以及特种电气设备等,扮演电气隔离、结构支撑和安全保护的角色。然而,理论和实践均表明气固界面(沿面)易发生放电和闪络,导致绝缘系统故障,严重威胁高压电器的安全稳定运行。目前基本了解了影响沿面闪络的多种因素,但对气固界面放电特性和机理的认识仍有不足,绝缘性能提升方法有待深入研究。同时,电力系统及设备的低碳环保发展趋势,推动了了SF6混合气体/替代气体、电场调控绝缘材料、可修复/可回收绝缘材料等环保型气体和固体绝缘体系的快速发展。然而,

Uncovering correlates of decline and critical refuges for a threatened terrestrial mammal
Conservation Biology, EarlyView.Abstract Globally, the geographic ranges of numerous species are contracting. Identifying spatiotemporal patterns of threat impact can illuminate why species decline in some parts of their range but persist in others. We developed a correlative approach to identify species’ response thresholds and locate ecological refuge areas associated with ...

Gaoya dianqi, 2019 内充干燥空气的环保充气柜,绿色环保,是近几年的发展趋势之一。三工位隔离开关是该环保充气柜中的主要核心元件之一。为确保开关柜断电与接通的可靠运行,三工位隔离开关的可靠到位至关重要。文中针对环保充气柜,从机构传动和联锁装置两方面出发,通过增加双操作轴及相关联锁的方法,设计了一种12 kV环保充气柜用三工位隔离开关操作机构,实现隔离开关的隔离、导通和接地三个工位的灵活切换。该装置操作可靠、安全性高,并已广泛应用于XGNA-12型环保充气柜。

Scientists’ warning on the global destruction of rock outcrop ecosystems
Conservation Biology, EarlyView.Abstract Rock outcrops are geological formations that harbor a highly specialized biota adapted to harsh environmental conditions that differ from their surrounding landscapes. They are globally distributed, especially in old, highly weathered landscapes, and can function as habitat islands containing high levels of endemism and distinct evolutionary ...

Conservation Biology, EarlyView.Abstract Ecological niche models (ENMs) are used to assess the abiotic preferences of species by linking their occurrences to the environmental conditions in which they live. We developed a fossil‐informed ENM framework that integrates mid‐Holocene and modern occurrences to test niche stability and reconstruct abiotic niche characteristics for four ...

Exploring legal‐ and health‐risk messaging to reduce demand for elephant skin
Conservation Biology, EarlyView.Abstract Asian elephants (Elephas maximus) are poached for an illegal trade in their skins, which are used in traditional medicine in Africa and Asia. We explored whether messages about the legal and health risks of using elephant skin for medicinal purposes (stomach illness) could reduce such consumption.

Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT The development of structurally stable anodes with high capacities and long cycle lives is essential for the development of potassium–ion batteries. Conversion‐type anodes have attracted considerable attention in potassium–ion batteries (PIBs) due to their high theoretical capacities.
