Fig. 1. The time course in oxygen consumption (ml O2 h-1
g-1) between coastal (open circles) and inland (closed circles)
T. elegans on a lyophilized fish diet (A) and slug diet (B). The
standard metabolic rates of coastal specialist snakes and inland generalist
snakes were 0.058 ml O2 h-1 g-1 and 0.70 ml
O2 h-1 g-1 at 30±1°C, respectively
(P=0.07). Each data point represents the mean metabolic value of a
group of snakes. The total energy devoted to SDA was calculated for each snake
by subtracting SMR from total metabolic rates during digestion. Postprandial
metabolic rates reached maximal levels of 3.0- to 4.0-fold resting rates and
lasted nearly 80-110 h.
