  • Values are means ± s.d. MRs are from the DLW two-sample technique (Speakman, 1997). Final column gives the absolute percent difference between the DLW-derived MR and the respirometry-derived MR. For Eqn 3, the body pool estimate (No and Nd) are used for each individual turtle and these can be found in Table 1
