Estimates of the phylogenetic signal for each variable using Pagel's Lambda.

The results are presented for one of the ten randomly selected polytomy resolved trees for the two different phylogenies. A λ value of 1 indicates that the trait gradually accumulates changes over time in a Brownian motion process. A λ values of 0 indicates that no phylogenetic signal is present and that traits have evolved in response to selective processes. The superscript values are likelihood ratio tests different from 0 and 1. Sample size is 53 for all variables except day depth (50).本结果针对两类不同系统发育（phylogeny）的十棵随机选取的多歧分支解析树之一呈现。当λ值为1时，代表性状随时间以布朗运动（Brownian motion）过程逐步累积变异；当λ值为0时，则表明不存在系统发育信号（phylogenetic signal），性状演化由选择过程主导。上标数值代表经似然比检验证实与0和1存在显著差异的结果。除日深（day depth）变量的样本量为50外，其余所有变量的样本量均为53。
