埃及獴在欧洲分布边缘扩张如何量化：《科学报告》以专家问卷结合动态占有模型追踪、11 月 11 日刊出
西班牙 — 《科学报告》2026 年 11 月 11 日刊出 Pablo Ferreras 等人的研究，题为以专家问卷结合动态占有模型的新方法评估一种广适性食肉动物的分布扩张。研究对象是埃及獴，研究地点在其分布的欧洲边缘。
论文摘要指出，尽管全球正处于生物多样性危机，许多中型捕食者的分布范围却在扩大，主要由其广适性的生活史和顶级捕食者衰退所驱动。量化这类扩张并找出背后动因具有挑战性，需要创新的方法学路径，这正是本研究的目标。
方法方面，研究团队把专家问卷与动态占有模型结合起来。问卷对象包括卡斯蒂利亚-拉曼恰地区的环境巡护人员，论文致谢部分特别提到各分区与省级协调员协助推动巡护人员参与在线问卷。研究所属项目编号 SBPLY/17/180501/000184，由卡斯蒂利亚-拉曼恰地区政府和欧洲区域发展基金资助。
作者团队来自西班牙多家机构，包括狩猎资源研究所、先进社会研究所、埃斯特雷马杜拉大学、马拉加大学和国家农业与食品研究技术研究所等。论文通讯作者为 Pablo Ferreras，作者声明无利益冲突，采用开放获取方式发表。本稿以论文摘要、作者与资助信息为准，未刊出的具体模型数值不在本稿推断。
How to Quantify the Egyptian Mongoose Expansion at the European Edge of Its Range: Scientific Reports Paper Combines Expert Questionnaires with Dynamic Occupancy Models, Published November 11
Spain — Scientific Reports published a study by Pablo Ferreras and colleagues on November 11, 2026, titled on assessing the range expansion of a generalist carnivore by a novel approach combining questionnaires to experts and dynamic occupancy models. The species studied is the Egyptian mongoose, Herpestes ichneumon, at the European edge of its range.
The abstract states that despite the ongoing global biodiversity crisis, the geographic ranges of many mesopredators are expanding, largely driven by their generalist life histories and the decline of apex predators. Quantifying these expansions and identifying their underlying drivers remain challenging and require innovative methodological approaches, which the study set out to provide.
The team combined questionnaires to experts with dynamic occupancy models. The acknowledgements thank the environmental rangers of Castilla-La Mancha for taking part in the online questionnaire survey, and their demarcation and provincial coordinators for helping to engage the rangers. The study is part of research project SBPLY/17/180501/000184, funded by the regional Government of Castilla-La Mancha and the European Regional Development Fund.
The authors are based at Spanish institutions including the Instituto de Investigación en Recursos Cinegéticos, the Instituto de Estudios Sociales Avanzados, the Universidad de Extremadura, the Universidad de Málaga and INIA-CSIC. Correspondence is to Pablo Ferreras, the authors declare no competing interests, and the article is published open access. This report follows the abstract, author and funding information of the paper and does not infer model values not stated there.
