Perceived costs as drivers of wildlife management preferences in rural Tanzanian communities
Conservation Biology, EarlyView.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.

无人机技术在中国印度野牛(Bos gaurus)野外救护中的首次应用
野生动物学报, 2020 在中国云南省西双版纳地区首次利用无人机技术野外救护一头受伤野生印度野牛。详细介绍了在无人机上安装麻醉吹管,采用无人机监测、寻找受伤野牛并对其进行远程麻醉,以及该野牛获救后无人机对其进行持续监测等过程。总结这一成功案例,我们认为无人机技术值得在大型哺乳动物,特别是攻击能力强的大型哺乳动物的野外监测和救护中进一步应用。

Learning Styles, Engagement and Anxiety in AI‐Mediated Writing: A Multimodal Feedback Study
International Journal of Applied Linguistics, EarlyView.ABSTRACT Artificial intelligence (AI) tools now permeate English academic writing. However, evidence on how feedback modalities align with student differences and with psychological mechanisms remains limited. Prior work often reduced learning styles to simple matches with delivery modes and treated learning engagement and writing anxiety as peripheral.

Do Criminalization Policies Impact Local Homelessness?
Policy Studies Journal, Volume 54, Issue 3, August 2026.ABSTRACT Local criminalization policies draw on the logic of deterrence to levy costs on individuals who engage in behaviors that are closely associated with various public concerns, such as those criminalizing behaviors associated with homelessness, thereby potentially reducing community‐level costs.

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~
