Estimated tree using data from Johnson et al., (2009)

Our estimated tree generated using data from Johnson et al., (2009). The tree is based on the nuclear gene (EF-1α) and mitochondrial genes (12S and COI) for 38 species in the genus Columbicola and one outgroup, Oxyliperurus chiniri. The accession numbers were taken from Johnson et al., (2007). The tree was estimated using BEAST v2.1.3 (Bouckaert et al., 2014), allowing the topology to vary. We used a GTR + Γ model of nucleotide evolution with separate partitions for each gene and codon position, a relaxed log-normal clock, and a birth-death prior. Further information and full references can be found in the supplementary material of our paper.本研究基于Johnson等人（2009）的数据集构建了估算得到的系统发育树。该系统发育树以Columbicola属的38个物种以及1个外类群Oxyliperurus chiniri为研究对象，基于核基因（EF-1α）与线粒体基因（12S、COI）序列构建而成。所用的基因登录号源自Johnson等人（2007）的研究。本研究使用BEAST v2.1.3（Bouckaert等人，2014）进行系统发育树的估算，允许拓扑结构发生变异。我们采用GTR+Γ核苷酸进化模型，对每个基因及密码子位置分别设置分区，并使用宽松对数正态分子钟与生灭先验分布。更多详细信息及完整参考文献可参见本研究论文的补充材料。
