... rhythms during portions of increasing temperature ramps plotted as a function of temperature on a logarithmic scale. Each color corresponds to an individual animal. A line was fitted to data points for each animal's heart frequencies to estimate the Q10. (D) Critical temperature of the heart rhythm...

... was significant (see text for statistics). Fig. 4. Q10 computed for each individual, measured at two temperatures(open circles, 7–17°C; filled circles, 17–27°C), versus body mass. Only the regression between Q10 and body mass in the 7–17°C range was significant (see text for statistics). Fig. 5...

... is horizontal (broken line). Fig. 2. Outcome of the down–up (DU) protocol in Fig. 1 portrayed as ln(V̇O2) versus body temperature Tb (A) and the value of ln(V̇O2) adjusted for the Q10 effect versus Tb (B). Data representing Phase I (cooling) are indicated by downward pointing triangles,Phase II (maximum...

... for individual scorpions. Mass-independent metabolic rate was calculated by dividing metabolic rate by (body mass) 0.885 (mass in g; see equation 1 ). These data were used to calculate values of the temperature coefficient, Q10. Each line corresponds to an individual scorpion and is calculated from 5–15...
