Appendix B. Additional tables on the phylogenetic signal of metabolic rates in each lineage.

TABLE B1. PGLS analysis on the strength of the phylogenetic signal (λ) of (a) basal metabolic rate (BMR) and (b) body mass, tested individually, in each lineage. The first two columns report the maximum likelihood (ML) λ value and the log-likelihood score (Lh) of a model with λ=ML. The following 3 columns report the Lh when λ is forced to be equal 0, the LR test for the comparison with the model with λ=ML and its associated P value. The last 3 columns report the Lh of a model in which λ is forced equal 1, the LR test and P value for the comparison versus the model with λ=ML. Models with a statistically higher Lh score, as assessed with LR test, provide a better fit to the data.

TABLE B2. PGLS analysis on the strength of the phylogenetic signal (λ) of (a) field metabolic rate (FMR) and (b) body mass, tested individually, in each lineage. The first two columns report the maximum likelihood (ML) λ value and the log-likelihood score (Lh) of a model with λ=ML. The following 3 columns report the Lh when λ is forced to be equal 0, the LR test for the comparison with the model with λ=ML and its associated P value.
