Extended Data Fig. 9 | Relationship between Φcrit and the ratio of
maximum-to-resting metabolic rates (MMR/RMR), among all species with
empirical estimates of both parameters. Blue dots, species with empirical
estimates of both parameters (Supplementary Table 1). Lines of constant wR
(see equation ( 9 ) are shown for a sustained metabolic rate that is equal to the
resting rate (SMS = 1; wR = 1; blue line), the maximum metabolic rate (SMS = FAS;
wR = 0; red line) or the mean apparent species value (wR = 0.4; green line) in
which sustained the metabolic rate is approximately midway between minimal
(resting) and maximal rates. Independent geochemical estimate of SMS based
on carbon isotopes in the otoliths of Atlantic cod^28 are shown as a triangle.
