Convergent evolution of the army ant syndrome and congruence in big-data phylogenetics

This study provides a phylogeny of the ant subfamily Dorylinae by generating sequence data from 2,500 ultraconserved element loci from 154 species comprising 27 genera. Using these data we reconstruct complete genus-level phylogeny using concatenated Bayesian and maximum-likelihood as well as species-tree approaches, estimate divergence dates and diversification rates for the subfamily, and investigate the influence of model mis-specification on phylogenetic analysis. Deposited here are the adapter-trimmed raw read Illumina sequence data, containing both on-target reads assembling to UCE loci and off-target reads本研究针对涵盖27个属的154个物种，从2500个超保守元件位点（ultraconserved element loci，UCE）生成测序数据，以此构建了行军蚁亚科（Dorylinae）的系统发育树。本研究利用上述数据，采用串联贝叶斯法、最大似然法以及物种树分析方法，重建了完整的属级系统发育树；同时估算了该亚科的分化时间与物种多样化速率，并探究了模型误设定对系统发育分析的影响。本研究存档了经接头修剪的原始Illumina测序读段数据，该数据包含可组装至超保守元件位点的靶向读段与非靶向读段。
