O2max
(triangles) and morphometric estimate of total volume of muscle capillaries
V(c) (squares) in 11 species based on whole body sampling.
The slope is 0.962 for
O2max (95%
CL=0.829-1.096; F=265, d.f.=1,9, P<0.00001), and 0.984
for V(c) (95% CL= 0.909-1.056; F=916, d.f.=1,9,
P<0.00001); the two regressions are identical. Numbers at the
bottom identify species, as in Fig.
