Table 3 Analyses of fruit type, growth form, and climate regions treated as dependent variables with no independent variables using logistic regression (phyloglm, Ho and Ane 2014). Values of α is the parameter from the Ornstein-Uhlenbeck model of evolution, and lower values correspond to stronger phylogenetic signal. The analyses were performed with both the full phylogeny and the 0.67-threshold phylogeny in which nodes in the top 1/3 of the phylogeny were collapsed.
