Table A3.

Correlation of critical thermal limits (as measured by CT_min and CT_max) and thermal range of tolerance with temperature during development and standard metabolic rate in X. laevis tadpoles. ρ (correlation coefficient) and P for Spearman’s rank correlation. Significance was set at P < 0.05. T4 = high TH levels; SP = low TH levels
