AEROBIC METABOLISM IN SNAPPING TURTLES, CHELYDRA-SERPENTINA, AFTER THERMAL ACCLIMATION

1. 1. Oxygen consumption of resting and active snapping turtles at 10, 20 and 30°C was measured following acclimation to 10 and 25°C. 2. 2. Cold acclimation results in depressed resting and active rates of oxygen consumption and in a decreased aerobic metabolic scope for activity; these changes facilitate hibernation. 3. 3. Warm-acclimated animals have a high aerobic capacity which supports aquatic and terrestrial activity. © 1978.
