Fig. 4. Resting individual oxygen pulse (ROP, circles) and active oxygen pulse (AOP, squares) for 22 king penguins plotted against the nutritional index NI (see text for details). The continuous line is the regression line between ROP and NI (ROP=1.0326+0.1761NI, r²=0.36, P=0.004), and the broken line is the regression line between AOP and NI (AOP=1.5637+0.36NI, r²=0.46, P=0.0007).
