Thousands of species are threatened by overexploitation, often driven by a complex interplay of local and global demand for various products-a dynamic frequently overlooked in wildlife trade policies. African pangolins, regarded as the world's most trafficked wild mammals, are a heavily exploited group for different reasons across geographic scales. However, it remains unclear how far the burgeoning trafficking of their scales to Asia for medicine drives their exploitation compared with local meat demand. Here, using data collected from questionnaires distributed to 809 hunters and meat vendors in Nigeria, the world's biggest hub for pangolin trafficking, we show that targeted pangolin hunts are uncommon in the country's largest pangolin stronghold. Instead, 97% of pangolins are captured opportunistically or during general hunting, with 98% of these caught for meat and mostly either eaten by hunters (71%) or traded locally (27%), potentially due to the meat's exceptionally high palatability. Meanwhile, around 70% of scales are discarded, with less than 30% sold. In addition, local meat prices are three to four times higher than those for scales. Our findings highlight the need to consider entire wildlife trade chains in international policies.
数千个物种受到过度开发的威胁,这往往是由对各种产品的本地和全球需求的复杂相互作用所驱动的——这种动态在野生动物贸易政策中常常被忽视。非洲穿山甲被视为世界上被贩运最多的野生哺乳动物,由于不同的原因,它们在不同地理区域都受到了严重的开发利用。然而,与当地对穿山甲肉的需求相比,其鳞片运往亚洲用于制药的新兴贸易在多大程度上推动了对它们的开发利用,目前仍不清楚。在这里,我们利用向尼日利亚(世界上最大的穿山甲贩运中心)809名猎人和肉贩发放问卷收集的数据表明,在该国最大的穿山甲栖息地,有针对性地捕猎穿山甲的情况并不常见。相反,97%的穿山甲是在机会主义捕猎或一般狩猎过程中捕获的,其中98%是为了获取肉,大部分被猎人吃掉(71%)或在当地交易(27%),这可能是因为穿山甲肉的适口性极高。与此同时,大约70%的鳞片被丢弃,只有不到30%被出售。此外,当地穿山甲肉的价格是鳞片价格的三到四倍。我们的研究结果凸显了在国际政策中考虑整个野生动物贸易链的必要性。
