背景：许多研究倾向于分散(殖民)而不是替代(过去的碎片化)事件来解释东亚-北美的分布模式。然而，在植物中，东亚和北美西部之间的脱节很少用系统发育、分子测年和生物地理方法相结合的方法来研究。与此同时，东亚地区的生物地理格局仍鲜为人知。黄连属黄连。包括在北美，日本，大陆中国和台湾间断分布的15种。通过比较不同的生物地理模型，对黄连的历史生物地理学进行了推测。结果：黄连和马绍尔黄连的分裂发生在中新世中期(约15.47 Ma)。黄连在晚中新世早期(约9.55 Ma)开始多样化。中新世晚期的更替事件导致了东亚和北美西部的分离。在东亚，从亚洲大陆到日本和从日本到台湾的扩散分别发生在约4.85 Ma和约1.34 Ma。结论：我们的分析提供了证据，证明替代和扩散事件对黄连目前的分布和特有分布起到了重要作用，可能是由于海平面变化、造山过程和中中新世以来日益干燥和凉爽的气候所致。
Background:Numerous studies have favored dispersal (colonization) over vicariance (past fragmentation) events to explain eastern Asian-North American distribution patterns. In plants, however the disjunction between eastern Asia and western North America has been rarely examined using the integration of phylogenetic, molecular dating, and biogeographical methods. Meanwhile, the biogeographic patterns within eastern Asia remain poorly understood. The goldthread genus Coptis Salisb. includes 15 species disjunctly distributed in North America, Japan, mainland China, and Taiwan. We present a dated phylogeny for Coptis under the optimal clock model and infer its historical biogeography by comparing different biogeographic models.Results:The split of Coptis and Xanthorhiza Marshall occurred in the middle Miocene (ca. 15.47 Ma). Coptis started their diversification in the early late Miocene (ca. 9.55 Ma). A late Miocene vicariance event resulted in the eastern Asian and western North American disjunction in the genus. Within eastern Asia, dispersals from mainland Asia to Japan and from Japan to Taiwan occurred at ca. 4.85 Ma and at ca. 1.34 Ma, respectively.Conclusions:Our analyses provide evidence that both vicariance and dispersal events have played important roles in shaping the current distribution and endemism of Coptis, likely resulting from eustatic sea-level changes, mountain formation processes and an increasing drier and cooler climate from the middle Miocene onwards.
