The determination of standard metabolic rate
The effect of pC[O.sub.2] on standard metabolic rate
To determine any significant differences in the growth, compression strength, and standard metabolic rate of the shell among family lines of C.
Intrapopulational variation in the standard metabolic rate
of insects: repeatability, thermal dependence and sensitivity (Q(10)) of oxygen consumption in a cricket.
Standard metabolic rate data for each individual were plotted against time and averaged over all hours (range 1-7 hours) after the outflowing P[O.sub.2] stabilized.
Routine and standard metabolic rate data at each temperature were fitted to the allometric equation MR= a x [M.sup.b] by using nonlinear, iterative Gauss-Newton regression (Brill, 1979, 1987).
The lowest mean M[O.sub.2] (deemed the standard metabolic rate
) was observed on day 7 (17.1 [+ or -] 1.53 [mu]g [O.sub.2] [h.sup.-1] [g.sup.-1]), 4 days after cessation of feeding (Fig.
Notably, eurythermal cold-water animals are characterized by elevated standard metabolic rates
in comparison with temperate and tropical confamilial species.
