Fig. 1. Resting metabolic rate (RMR) as a function of body mass for
lactating female mice (filled circles; y=18.16+1.25x;
N=28) and non-reproductive female mice (N=15) measured on
two separate occasions: NR-1 (open circles;
y=2.88+0.51x) and NR-2 (open squares;
y=5.99+0.41x). Both lactating and non-reproductive
mice were exposed to 30°C.
