Differentiation of island lineages from mainland relatives and radiation after initial colonization are two important processes generating island diversity. Both of these processes are influenced by colonization dynamics and contemporary connections between island species and their source populations. The classic island progression rule model, that is dispersal from mainland to older islands and subsequently to younger islands, can be considered a null hypothesis, particularly for islands that are geographically aligned perpendicular to the mainland coast with ages inversely proportional to distance from the mainland. Alterations to this pattern have been reported, particularly in archipelagos that are geographically closely adjacent to mainland source populations. Here we aim to integrate genomic and environmental niche data to infer the colonization history of a Canary endemic species and to understand its current diversity patterns.

加那利群岛特有的Lavatera acerifolia（锦葵科）的定殖历史通过基因分型和测序及利基模型揭示

岛屿血统与大陆亲属的区别以及最初定居后的辐射是产生岛屿多样性的两个重要过程。这两个过程都受到殖民动态和岛屿物种与其来源种群之间当代联系的影响。从大陆到较旧的岛屿，再到较年轻的岛屿的经典岛屿演变规则模型可以被认为是零假设，尤其是对于地理上垂直于大陆海岸排列且年龄与离大陆距离成反比的岛屿。已经报道了这种模式的变化，特别是在地理上与大陆来源种群紧密相邻的群岛上。
