  1. The regression coefficients were calculated according to the function lng=a 0a 1 T+a. The methods are as follows: (1) average value, (2) mode value, and (3) multiple-peak consideration. Values in parentheses are bootstrap estimates of the standard error of coefficients. g, weight-specific growth rate (1/day); M, body mass (μg); T, temperature (K); E, activation energy (eV), E = -a 1 × k; k, Boltzmann's constant (eV/K); n, sample size; MSE of cross-validation, mean squared error calculated from the 10-fold cross-validation analysis.
