  1. 1 Units for all measures other than percentages are μL CO2 hr-1 ± S.E. for 5 larvae. See methods for description of mass correction.
  2. 2 Within each trait, different letters indicate significant differences between copy number genotypes (P Tukey’s <0.05).
  3. 3 Q 10 = 36 ° C RMR 22 ° C RMR 10 36 − 22 .
  4. 4 Recovery was calculated from the mean metabolic rate during the first 20 min following return to 22°C and the final 20 minutes of the respirometry experiments as described in the methods.
