Organismal rates increase with temperature until an optimum (or maximum) is reached. The sensitivity of the rising part of that relationship can be described the activation energy (E, in eV). As described in PNAS, Dell et al. (7) document considerable variation in E. This figure shows the thermal sensitivity of rates for various E values (next to each curve), which were standardized to have the same value at 313 K (40 °C). Plotted are E values (0.2, 1.2 eV) that bracket most estimates, the canonical value of MTE (0.65, dashed gray), as well the mean values for escape velocity (0.39 eV, blue) and for voluntary velocities (0.52 eV, red): the relatively low E for escape velocity may reflect selection for the life/dinner principle, as described by Dell et al. (7).
