The evolutionary importance of southern mountain ranges has been noted for alpine as well as arctic–alpine plants. However, it remains unclear whether these isolated marginal populations of cold‐adapted species have contributed to the establishment of their current widespread distribution. We aim to explore the molecular evidence for the recent northward migration of alpine snow‐bed species in the northern Pacific region.

北部太平洋地区广泛存在的高山雪床草本樱草报春花（Primulaceae）的东亚起源

对于高山以及北极-高山植物，已经注意到了南部山脉的进化重要性。然而，目前尚不清楚这些孤立的冷适应物种边缘种群是否有助于建立其目前的广泛分布。我们旨在探索北太平洋地区高山雪床物种最近向北迁移的分子证据。
