美国加州大学Thomas B. Smith，Timothy C. Bonebrake和Jen C. Tinsman共同合作，近期取得重要工作进展。他们通过基因组分析揭示了从非洲到亚洲穿山甲的偷猎热点和非法贸易。相关研究成果
据介绍，白腹穿山甲是世界上被贩运量最大的哺乳动物，正面临灭绝的风险。减少非法野生动物贸易需要了解其起源。
使用基因组方法追踪2012年至2018年间从非洲已知地理位置采集的111个样本和从亚洲采集的643个鳞片，研究人员发现偷猎压力随着时间的推移从西非向中非转移。最近，喀麦隆南部边境出现了大量偷猎活动。利用近100万只非洲穿山甲的缉获量数据，研究人员确定尼日利亚是一个重要的贩运中心，在那里，鳞片被收集并转运到亚洲市场。
总之，这种从源头到目的地的方法为破坏非法野生动物贸易和指导反贩运措施提供了新的机会。

Abstract: The white-bellied pangolin (Phataginus tricuspis) is the world’s most trafficked mammal and is at risk of extinction. Reducing the illegal wildlife trade requires an understanding of its origins. Using a genomic approach for tracing confiscations and analyzing 111 samples collected from known geographic localities in Africa and 643 seized scales from Asia between 2012 and 2018, we found that poaching pressures shifted over time from West to Central Africa. Recently, Cameroon’s southern border has emerged as a site of intense poaching. Using data from seizures representing nearly 1 million African pangolins, we identified Nigeria as one important hub for trafficking, where scales are amassed and transshipped to markets in Asia. This origin-to-destination approach offers new opportunities to disrupt the illegal wildlife trade and to guide anti-trafficking measures.
