Model fit and parameter estimation for analyses of continuous traits. Phylogenetic signal was assessed using Blomberg’s K (2003) and Pagel’s λ (Pagel 1999). Statistical significance for these indices was based on comparison to a non-phylogenetic model (K = 0, λ = 0), with a significant P-value indicating rejection of the non-phylogenetic model.

针对连续性状分析的模型拟合与参数估计。本研究采用Blomberg’s K（2003）与Pagel’s λ（Pagel 1999）评估系统发育信号（phylogenetic signal）。上述两类指数的统计学显著性通过与非系统发育模型（K=0，λ=0）的比较进行判定，当P值达到显著性水平时，即可拒绝该非系统发育模型。
