<b>Karst habitat islands drove a largely non-adaptive and allopatric radiation in </b><b><i>Petrocodon </i></b><b>(Gesneriaceae)</b>

This repository contains all resulting phylogenies and custom scripts used in our study on the phylogenomics and diversification of the karst-endemic plant genus Petrocodon. In this study, we inferred well-resolved phylogenies for the genus Petrocodon using both concatenation- and coalescent-based methods. Then, we integrated genomic sequence with morphological, geographic, and paleoclimatic data to evaluate the relative roles of ecological and neutral processes in diversification. Our results support a predominantly non-adaptive radiation in Petrocodon, where spatial opportunity, drift, and reticulate evolution jointly shaped speies richness and striking phenotypic diversity within the genus.本数据集仓库包含了我们针对喀斯特特有植物属石山苣苔属（Petrocodon）的系统发育基因组学与演化多样化研究中所使用的全部系统发育结果与自定义脚本。本研究采用基于串联拼接法与溯祖模型的两类分析方法，对石山苣苔属构建了高分辨率的系统发育树。随后，我们将基因组序列数据与形态学、地理学及古气候数据相结合，以评估生态过程与中性过程在该类群演化多样化中的相对作用。研究结果表明，石山苣苔属的演化辐射整体以非适应性辐射为主：空间机遇、遗传漂变与网状进化共同塑造了该属的物种丰富度与显著的表型多样性。
