Abstract

We analyse for the first time the genetic diversity within Ptyodactylus oudrii across the Maghreb. Two mitochondrial (12s rRNA and 16s rRNA) and two nuclear (C-mos and ACM4) markers are used. The results confirm the specific status of P. oudrii and show high levels of intraspecific variability, indicative of species complex. Lineages found are geographically concordant, and show similar patterns to that found in other species from the region. The study highlights once more the importance of the region as a source of genetic diversity.

摘要

我们首次分析了整个马格里布地区奥氏攀蜥的遗传多样性。使用了两个线粒体(12s rRNA 和 16s rRNA)和两个核(C-mos 和 ACM4)标记。结果证实了奥氏攀蜥的特殊地位,并显示出高水平的种内变异性,表明存在物种复合体。发现的谱系在地理上是一致的,与该地区其他物种的模式相似。该研究再次强调了该地区作为遗传多样性来源的重要性。
