Estimates of heterogeneity I2 (%) from the normalized-mean meta-analysis and the CV meta-analysis for the best model with all random factors for the 3 different contexts and all contexts.

The MLPMA allowed partitioning I2 among varying levels. Posterior mean and upper and lower 95% CIs for each estimate of I2 are provided. H2 is phylogenetic heritability, the proportion of variability in the data attributable to the phylogenetic component of MLPMA calculated following Nakagawa and Santos [71]. CI, credible interval; CV, coefficient of variation; MLPMA, multilevel phylogenetic meta-analysis. (XLSX)
