We present a mtDNA analysis of Podocnemis expansa (n = 81) and Podocnemis unifilis (n = 228) turtles traded in Peru to evaluate the potential origin of these animals. In particular, we were interested in the relationship between samples reported in the Iquitos markets (IMs) and a Pacaya Samiria Natural Reserve (PSNR) where illegal hunting is presumed. Our mtDNA data showed that, for both species, all haplotypes found within the PSNR were observed in the IM, and that these markets also displayed haplotypes not documented in the reserve. This suggests that the IMs are recipients of Podocnemis turtles from within and outside the PSNR. The fact that most of the haplotype diversity observed in the markets was not found within the PSNR strongly suggests that Podocnemis genetic diversity is exploited in areas where conservation actions are limited. Hence, we recommend expanding Podocnemis conservation efforts outside of protected areas.
我们对在秘鲁交易的潘氏侧颈龟（Podocnemis expansa，n = 81）和单峰侧颈龟（Podocnemis unifilis，n = 228）进行了线粒体DNA分析，以评估这些动物的潜在来源。特别是，我们对伊基托斯市场（IMs）报告的样本与帕卡亚-萨米里亚自然保护区（PSNR）之间的关系感兴趣，据推测该保护区存在非法捕猎行为。我们的线粒体DNA数据显示，对于这两个物种，在PSNR内发现的所有单倍型在IM中都有观察到，并且这些市场还展示了保护区中未记录的单倍型。这表明IMs是来自PSNR内外的潘氏侧颈龟的接收地。市场中观察到的大多数单倍型多样性在PSNR内未被发现，这一事实强烈表明，在保护行动有限的地区，潘氏侧颈龟的遗传多样性正在被利用。因此，我们建议在保护区之外扩大对潘氏侧颈龟的保护工作。
