Cold‐adapted species had their largest distribution areas during glacial periods, whereas the subsequent interglacials led to retreats of these taxa into mountain ranges and more northern regions, but existing data are not sufficient for generalizing these range dynamics. To improve our knowledge of the different phylogeographical patterns existing for cold‐adapted species, we examined two closely related butterfly species of the genus Boloria with alpine disjunct and arctic–alpine distribution respectively.

低温适应的蝴蝶物种群Boloria pales / napaea（Nymphalidae）间系间正在驱动物种形成和种内分化。

冷适应物种在冰川期具有最大的分布区域，而随后的间冰期导致这些类群退缩到山脉和更北部的地区，但是现有数据不足以概括这些范围动态。为了提高我们对冷适应物种存在的不同植物地理学模式的了解，我们研究了Boloria属的两个紧密相关的蝴蝶物种，分别具有高山分离和北极-高山分布。
