进化谱系的地理分布和二次接触时的基因流模式提供了对分化和物种形成过程的深入了解。我们探索了伊比利亚半岛普通蜥蜴胎生蜥蜴（= Lacerta vivipara）的进化史，并测试了比利牛斯山脉和坎塔布连山脉在限制基因流动和驱动谱系隔离和分化方面的作用。我们还评估了二次接触时谱系间的基因渗入模式，并测试了高海拔跨山殖民在解释遗传多样性空间模式中的作用。我们使用 mtDNA 序列数据和全基因组 AFLP 位点来重建谱系之间的系统发育关系，并测量遗传结构。 mtDNA 中的主要遗传分裂通常对应于先前报道的比利牛斯山脉的法国和西班牙一侧，这与全基因组 AFLP 数据形成鲜明对比，后者显示了西班牙西北部与其他地区之间的主要分裂。两种类型的标记都支持四个不同且地理上一致的遗传群体的存在，这与主要的地形障碍一致。两个数据集都揭示了比利牛斯地区谱系之间存在三个独立的接触带，一个位于巴斯克低地，一个位于比利牛斯山脉西部的低海拔山脉，一个位于比利牛斯山脉中部的法国一侧。后者显示了最近从西班牙跨比利牛斯山脉高海拔入侵法国的遗传证据。主要谱系的分布和年龄与更新世起源一致，并且比利牛斯山脉和坎塔布连山脉在大地理范围内推动胎生珠虫谱系的分离和分化中发挥的作用。然而，山脉并不总是传播的有效障碍，并且未能阻止最近的高海拔跨比利牛斯入侵，导致不同谱系之间的不对称渗入。接触区遗传结构模式和基因渗入的细胞核不一致表明选择可能涉及不同规模。缝合带是研究谱系形成和物种形成的重要区域，我们的研究结果表明，生物地理屏障可以在不同的脊椎动物和无脊椎动物类群中产生明显不同的系统发育地理学模式。
The geographic distribution of evolutionary lineages and the patterns of gene flow upon secondary contact provide insight into the process of divergence and speciation. We explore the evolutionary history of the common lizard Zootoca vivipara (= Lacerta vivipara) in the Iberian Peninsula and test the role of the Pyrenees and the Cantabrian Mountains in restricting gene flow and driving lineage isolation and divergence. We also assess patterns of introgression among lineages upon secondary contact, and test for the role of high-elevation trans-mountain colonisations in explaining spatial patterns of genetic diversity. We use mtDNA sequence data and genome-wide AFLP loci to reconstruct phylogenetic relationships among lineages, and measure genetic structure. The main genetic split in mtDNA corresponds generally to the French and Spanish sides of the Pyrenees as previously reported, in contrast to genome-wide AFLP data, which show a major division between NW Spain and the rest. Both types of markers support the existence of four distinct and geographically congruent genetic groups, which are consistent with major topographic barriers. Both datasets reveal the presence of three independent contact zones between lineages in the Pyrenean region, one in the Basque lowlands, one in the low-elevation mountains of the western Pyrenees, and one in the French side of the central Pyrenees. The latter shows genetic evidence of a recent, high-altitude trans-Pyrenean incursion from Spain into France. The distribution and age of major lineages is consistent with a Pleistocene origin and a role for both the Pyrenees and the Cantabrian Mountains in driving isolation and differentiation of Z. vivipara lineages at large geographic scales. However, mountain ranges are not always effective barriers to dispersal, and have not prevented a recent high-elevation trans-Pyrenean incursion that has led to asymmetrical introgression among divergent lineages. Cytonuclear discordance in patterns of genetic structure and introgression at contact zones suggests selection may be involved at various scales. Suture zones are important areas for the study of lineage formation and speciation, and our results show that biogeographic barriers can yield markedly different phylogeographic patterns in different vertebrate and invertebrate taxa.
