BACKGROUND
Atlantolacerta andreanskyi is an enigmatic lacertid lizard that, according to the most recent molecular analyses, belongs to the tribe Eremiadini, family Lacertidae. It is a mountain specialist, restricted to areas above 2400 m of the High Atlas Mountains of Morocco with apparently no connection between the different populations. In order to investigate its phylogeography, 92 specimens of A. andreanskyi were analyzed from eight different populations across the distribution range of the species for up to 1108 base pairs of mitochondrial DNA (12S, ND4 and flanking tRNA-His) and 2585 base pairs of nuclear DNA including five loci (PDC, ACM4, C-MOS, RAG1, MC1R).
RESULTS
The results obtained with both concatenated and coalescent approaches and clustering methods, clearly show that all the populations analyzed present a very high level of genetic differentiation for the mitochondrial markers used and are also generally differentiated at the nuclear level.
CONCLUSIONS
These results indicate that A. andreanskyi is an additional example of a montane species complex.
背景
安特托拉塞塔·安德烈亚斯基（Atlantolacerta andreanskyi）是一种神秘的蜥蜴，根据最近的分子分析，它属于 Eremiadini 部落，蜥蜴科。它是一种山地专家，仅限于摩洛哥高阿特拉斯山脉的 2400 米以上地区，不同种群之间显然没有联系。为了研究其系统地理学，我们对来自该物种分布范围内的八个不同种群的 92 个安特托拉塞塔·安德烈亚斯基样本进行了分析，其线粒体 DNA（12S、ND4 和侧翼 tRNA-His）长达 1108 个碱基对，核 DNA 包括五个基因座（PDC、ACM4、C-MOS、RAG1、MC1R）长达 2585 个碱基对。
结果
无论是采用连锁和聚合法还是聚类方法，所得结果都清楚地表明，所有分析的种群在使用的线粒体标记中都表现出非常高的遗传分化水平，而且在核水平上也普遍分化。
结论
这些结果表明，A. andreanskyi 是另一个山地物种复合体的例子。
