Fig. 5. Rate of oxygen consumption (O2) as a function of heart rate (fH) for 24 adult king penguins walking on a treadmill (grey symbols, the grey line is the regression equation: O2=3.39fH-136.86, r2=0.63, P<0.001; data are from Froget et al., 2001) and for 26 resting adults exposed to different temperatures (open squares, the black line is the regression equation: O2=1.09fH+26.10, r2=0.46, P<0.001).
