热带岛屿是著名的进化研究的天然实验室。热带群岛的谱系辐射是研究殖民、物种形成和灭绝过程如何塑造生物多样性模式的理想系统。岛上画眉在印度太平洋的扩张代表了所有鸣禽物种中最大但最令人困惑的岛屿辐射之一。岛上画眉在其分布范围内呈现出复杂的明显的羽毛变化，可以说是世界上最多型的鸟类。它是一种定居的物种，主要局限于山地森林，但它已经占领了横跨地球四分之一的广阔岛屿地区。我们对岛上画眉种群进行了全面采样，获得了全基因组SNP数据，并利用这些数据重建了其系统发育、种群结构、基因流和人口统计学历史。岛上画眉从迁徙的古北祖先进化而来，并在更新世期间在印度太平洋地区爆发，种群之间有许多基因流动的例子。其令人眼花缭乱的羽毛变化掩盖了从菲律宾到大Sundas， Wallacea和新几内亚到波利尼西亚的生物地理直观的殖民路径。岛画眉在印度太平洋山区的成功殖民可以从其祖先的流动性和对凉爽气候的适应来理解；然而，海拔范围的变化、羽毛的变化程度和其活动范围东部的明显扩散率，对其生物学提出了进一步有趣的问题。
Tropical islands are renowned as natural laboratories for evolutionary study. Lineage radiations across tropical archipelagos are ideal systems for investigating how colonization, speciation, and extinction processes shape biodiversity patterns. The expansion of the island thrush across the Indo-Pacific represents one of the largest yet most perplexing island radiations of any songbird species. The island thrush exhibits a complex mosaic of pronounced plumage variation across its range and is arguably the world’s most polytypic bird. It is a sedentary species largely restricted to mountain forests, yet it has colonized a vast island region spanning a quarter of the globe. We conducted a comprehensive sampling of island thrush populations and obtained genome-wide SNP data, which we used to reconstruct its phylogeny, population structure, gene flow, and demographic history. The island thrush evolved from migratory Palearctic ancestors and radiated explosively across the Indo-Pacific during the Pleistocene, with numerous instances of gene flow between populations. Its bewildering plumage variation masks a biogeographically intuitive stepping stone colonization path from the Philippines through the Greater Sundas, Wallacea, and New Guinea to Polynesia. The island thrush’s success in colonizing Indo-Pacific mountains can be understood in light of its ancestral mobility and adaptation to cool climates; however, shifts in elevational range, degree of plumage variation and apparent dispersal rates in the eastern part of its range raise further intriguing questions about its biology.
