Mammal trees used for simulations, based on estimate of Meredith et al. 2011.

Phylogenetic estimate of mammals and phylogenies used in simulations. Original tree is in 'Original Tree' tree block. 'Trees for simulation' tree block contains 100 trees with (i) branch lengths scaled to generation time and (ii) branch widths scaled to effective population size as described in Oliver (2013). Dated phylogenetic estimate was originally published in: Meredith, R. W. J. E. Janečka, J. Gatesy, O. A. Ryder, C. A. Fisher, E. C. Teeling, A. Goodbla, E. Eizirik, T. L. L. Simão, T. Stadler, et al. 2011. Impacts of the Cretaceous terrestrial revolution and KPg extinction on mammal diversification. Science 334:521-524.

本数据集涵盖哺乳动物的系统发育估计结果，以及模拟实验所用的各类系统发育树。原始系统发育树存放于「原始树」树模块中。「模拟用树」树模块包含100棵系统发育树：其一，分支长度已按世代时间进行缩放；其二，分支宽度已按有效种群大小（effective population size）进行缩放，具体缩放规则详见Oliver(2013)的研究。本数据集附带的带定年信息的系统发育估计结果，其原始发表文献如下：Meredith, R. W.、Janečka, J. E.、Gatesy, J.、Ryder, O. A.、Fisher, C. A.、Teeling, E. C.、Goodbla, A.、Eizirik, E.、Simão, T. L. L.、Stadler, T. 等，2011年。《白垩纪陆地革命与KPg灭绝对哺乳动物多样化的影响》，《科学》（*Science*），第334卷：521-524页。
