Fig. 3. Data from 108 trials of 18 individual Terrapene ornata walking on
a 24.1 deg. incline showing (A) rate of oxygen consumption versus
speed for all trials, (B) COT versus speed for all trials, and (C)
COTmin for up to 10 trials for each individual versus
speed. Dashed line is expected COT based on mass
(Full, 1989). Note, horizontal
axis is the same scale as in Fig.
2. Average resting
O2 (±1
s.d.) is shown as a filled circle at 0 m s–1.
