Table 2.

Parameters for the best-fit models for log BMR, as assessed by stepwise backwards elimination from a full model containing all the main effects and the interactions between temperature and precipitation variables. (For the phylogenetic model, λ=1 and AIC=−174.69. For the non-phylogenetic model, AIC=−153.07.)
