在高海拔地区，河流可以作为两栖动物的屏障。利用线粒体细胞色素B基因的1038个碱基对序列对横断山区21个居群的齿突蟾进行了分析。S.在基因树上，boulengeri形成了3个分支，每个分支都被限制在一个被雅砻江和大渡河两大水系隔开的山脊上。基因树的替代模式表明，这些河流在种群分化过程中起到了有效的屏障作用。另一方面，山脊可能促进了两栖动物的运动。种群内不间断的山脉的分支II和III，揭示了很少的遗传结构。北方分支I，窝藏大量的遗传变异，这可能是该地区的崎岖地形和异质性栖息地的后果。此外，一个外群种，腺齿突虎，形成了第四支，并嵌套在S。boulengeri，表明S. boulengeri可能是一个并系种或一个种复合体。
At high altitude, rivers may function as barriers for amphibians. We examined 21 populations of Scutiger boulengeri from the Hengduan Mountains with 1038 base pairs of mitochondrial cytochrome b gene sequences. The haplotypes of S. boulengeri formed three clades on the gene tree, and each clade was restricted to one mountain ridge separated by two major river systems, the Yalong River and the Dadu River. The vicariant pattern of the gene tree suggests that these rivers functioned as effective barriers during population differentiation. On the other hand, mountain ridges may have facilitated amphibian movement. Populations within the uninterrupted mountain ranges of clades II and III, revealed little genetic structure. The northern clade I, harboured a substantial amount of genetic variation, which might be the consequence of the rugged terrain and heterogeneous habitat of this area. Furthermore, one outgroup species, Scutiger glandulatus, formed the fourth clade and nested within S. boulengeri, suggesting that S. boulengeri is likely a paraphyletic species or a species complex.
