The genus Quercus is among the most widespread and species-rich tree genera in the northern hemisphere. The extraordinary species diversity in America and Asia together with the continuous continental distribution of a limited number of European species raise questions about how macro- and microevolutionary processes made the genus Quercus an evolutionary success. Synthesizing conclusions reached during the past three decades by complementary approaches in phylogenetics, phylogeography, genomics, ecology, paleobotany, population biology and quantitative genetics, this review aims to illuminate evolutionary processes leading to the radiation and expansion of oaks. From opposing scales of time and geography, we converge on four overarching explanations of evolutionary success in oaks: accumulation of large reservoirs of diversity within populations and species; ability for rapid migration contributing to ecological priority effects on lineage diversification; high rates of evolutionary divergence within clades combined with convergent solutions to ecological problems across clades; and propensity for hybridization, contributing to adaptive introgression and facilitating migration. Finally, we explore potential future research avenues, emphasizing the integration of microevolutionary and macroevolutionary perspectives.

Oaks:一个成功的进化故事。

栎属是北半球最广泛和物种最丰富的树属之一。在美洲和亚洲,物种的非同寻常的多样性以及有限数量的欧洲物种在大陆上的持续分布,引发了人们对宏观和微观进化过程如何使栎属进化成功的疑问。综合了过去三十年来通过系统发育学,系统地理学,基因组学,生态学,古植物学,种群生物学和定量遗传学等互补方法得出的结论,该综述旨在阐明导致橡树辐射和扩展的进化过程。从时间和地理的相对尺度上,我们得出橡树进化成功的四个总体解释:在种群和物种内积累了大型的多样性水库;快速迁移的能力有助于生态优先对宗族多样化的影响;进化枝内进化差异大,结合进化论解决进化枝上的生态问题;和杂交的倾向,有助于适应性渗入并促进迁移。最后,我们探索潜在的未来研究途径,强调微观进化和宏观进化观点的整合。有助于适应性渗入并促进迁移。最后,我们探索潜在的未来研究途径,强调微观进化和宏观进化观点的整合。有助于适应性渗入并促进迁移。最后,我们探讨了潜在的未来研究途径,强调了微观进化论和宏观进化论的融合。
