白腹穿山甲（Phataginus tricuspis）是世界上贩运量最大的哺乳动物，面临灭绝的危险。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没收情况并分析 2012 年至 2018 年间从非洲已知地理位置收集的 111 个样本和从亚洲查获的 643 个鳞片，我们发现偷猎压力随着时间的推移从西非转移到中非。最近，喀麦隆南部边境成为严重偷猎的场所。根据缉获近 100 万只非洲穿山甲的数据，我们确定尼日利亚是一个重要的贩运中心，鳞片在这里聚集并转运到亚洲市场。这种从出发地到目的地的方式为打击非法野生动物贸易和指导反贩运措施提供了新的机会。
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.
