MP-EST tree

Tree inferred in MP-EST; the STAR tree was topologically identical. Branch labels are coalescent branch lengths. Given the lack of infraspecific sampling, it is impossible to estimate tip branch lengths; coalescent programs generally plot these as the maximum possible value (here, 9) but these should be ignored. Internal branch estimates are correct assuming gene tree discord is solely due to the coalescent. Tree labels refer to specimen voucher numbers.

本研究采用MP-EST方法推断得到物种树，STAR树的拓扑结构与其完全一致。分支标签代表溯祖分支长度（coalescent branch lengths）。由于缺乏种下采样，无法估算末端分支的分支长度；溯祖分析软件通常将此类分支长度赋值为最大可能值（本研究中为9），但该类数值应予以忽略。若假定基因树冲突（gene tree discord）仅由溯祖过程导致，则内部分支的估算结果准确可靠。树的标签对应凭证标本编号。
