基于无人机遥感的黑龙江南瓮河国家级自然保护区驼鹿种群数量及空间分布调查
野生动物学报, 2023 2022年3月下旬，利用固定翼无人机对南瓮河国家级自然保护区内驼鹿（Alces alces）进行航拍调查，估算及分析保护区内驼鹿的种群数量、分布密度和生境因子之间的关系。结果表明：获取无人机影像17 818张，无人机样带拼接面积为206.9 km2。结合目视解译方式识别驼鹿并据此建立驼鹿无人机影像解译标志库。根据无人机样带解译结果，得到驼鹿的种群密度为（0.174±0.038）只/km2，估算出保护区驼鹿的种群数量为310~484只。驼鹿的分布及生境选择中生态因子的分析结果表明，驼鹿主要分布于海拔400~

Intangible drivers of tolerance shape human–elephant coexistence in Southwest China
People and Nature, Volume 8, Issue 8, Page 2763-2780, August 2026.Abstract Southwest China is home to a small but rapidly expanding population of Asian elephants (Elephas maximus), whose growth has intensified conflicts with people living in shared landscapes. These conflicts result in substantial economic losses and occasional human casualties. This coexistence paradox—where conservation success leads to significant

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”.

Perceived costs as drivers of wildlife management preferences in rural Tanzanian communities
Conservation Biology, Volume 40, Issue 4, August 2026.Abstract Effectively managing human–wildlife interactions is crucial for fostering coexistence on shared landscapes. Management options are most effective when aligned with the preferences of people directly affected by wildlife, yet little is known about how socioecological factors influence these preferences.
