Allometry of resting metabolic rate in cockroaches
1Dept. of Environmental, Population, and Organismic Biology, University of Colorado, Boulder 80309-0334.
Abstract:
1. Resting VO2 at 22.7 degrees C was 0.217 +/- 0.007 ml O2/g/hr in Nauphoeta cinerea of 0.51 +/- 0.008 g body mass. 2. Whole animal resting metabolic rate for 11 cockroach species scaled allometrically: VO2 = 0.261 M0.776. 3. Allometry of resting VO2 among cockroach species is similar to that in vertebrates, and is consistent with models based on both "elastic similarity" and "biological similitude."
