Fig. 4. _{O_2max} (triangles) and morphometric estimate of total volume of muscle mitochondria V_(mt) (circles) in 11 species based on whole body sampling. The slope is 0.962 for _{O_2max} (95% CL=0.829-1.096; F=265, d.f.=1,9, P<0.00001), and 0.956 for V_(mt) (95% CL=0.846-1.066; F=388, d.f.=1,9, P<0.00001); the two regressions are identical (r²=0.168, d.f.=1, P=0.683). Numbers at the bottom identify species: 1, woodmouse; 2, mole rat; 3, white rat; 4, guinea pig; 5, agouti; 6, fox; 7, goat; 8, dog; 9, pronghorn; 10, horse; 11, steer. From Weibel et al. (2004).
