Human‐Caused Leopard Deaths in Sri Lanka Are Concentrated in Central Highlands' Estate Mosaics: Evidence From 17 Years of Mortality Records 人为因素导致斯里兰卡豹死亡事件集中于中部高地种植园镶嵌景观:来自 17 年死亡记录的证据

Wildlife Letters, Volume 4, Issue 3, Page 107-117, September 2026.
Human‐caused leopard deaths in Sri Lanka averaged 9.65 ± 4.5 records year−1 over 17 years (2008–2024; n = 164), with records highly clustered in the central highland mosaic ecosystem. Mortality was dominated by adult males and driven primarily by snaring in plantation landscapes, and indicating an increase approximately 0.7–0.8 deaths per year.

Flexible, Robust Transparent Conductive Films With Excellent Electromagnetic Shielding Properties

Rare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT Transparent conductive films (TCFs) are indispensable components for next‐generation wearable electronics, intelligent robots, and electromagnetic interference (EMI) shielding devices. However, the fabrication of conventional random metallic mesh suffers from an inherent trade‐off between “randomness and controllability”.

Drivers of bat researchers’ intent to adopt field hygiene practices

Conservation Biology, Volume 40, Issue 4, August 2026.
Abstract Infectious disease is a growing threat to wildlife, with zoonotic transmission most likely at the human–wildlife interface. One underappreciated activity at this interface is fieldwork with wild animals, but associated risks can be mitigated through field hygiene (FH) practices, such as using personal protective equipment and other appropriate

饮用水中全氟和多氟烷基物质的污染特征及管控

Jingshui jishu
【目的】全氟和多氟烷基物质(PFASs)被广泛应用于各种工业产品和日常消费品中，已成为受到广泛关注的持久性有机污染物。环境水体中已普遍检出PFASs,人体通过饮水摄入是PFASs主要暴露途径之一，开展饮用水中PFASs赋存特征研究对于PFASs的防控至关重要。【方法】本文论述了PFASs的种类，除了包含全氟烷基羧酸(PFCAs)和全氟烷基磺酸(PFSAs)两大类传统PFASs外，还包含了新型PFASs的典型类别，并从直接排放和间接迁移两方面，对饮用水中PFASs的污染来源进行分析 ...

Large Cation‐Induced Lattice Distortion in Carbon‐Based High‐Entropy Oxides: Spin‐State Engineering and Broadband Microwave Absorption

Rare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT High‐entropy oxides (HEOs) are promising for microwave absorption but suffer from a trade‐off between impedance matching and attenuation, often requiring high filling ratios (> 50 wt%). Herein, we propose a “lattice‐spin” dual‐regulation strategy by introducing giant‐radius Bi into a single‐phase HEO solid solution.
