Fig. 5. Metabolic profiles of the HN (red), LN (blue), and CN (black) males (broken
lines) and females (solid lines) during a temperature ramp, ending at
CTmax for locomotor function (N=8 for each
group). Knockdown selection treatment did not affect significantly the
mass-specific
CO2 over the
experimental range of temperatures (P=1.000), whereas sex had a
strong effect (P=1.042x10-6). Specifically, males
had a higher mass-specific
CO2 throughout
the experiment.
