Table 2 Partial contribution of each factor (growth form, GF; climate region, CR; and phylogeny, PHY) to the variation in fruit type for the full phylogeny and the 0.67-threshold phylogeny in which nodes in the top 1/3 of the phylogeny were collapsed. The partial contribution of a factor to a model is obtained by computing the partial R2lik between the full model and the reduce model in which the factor is removed. The ΔlogLik is the change of log-likelihood between full and reduced models.
