Like many mammalian heterotherms, the big brown bat, Eptesicus fuscus, breathes intermittently during torpor. By exploiting this bat's preference to roost in crevices, we could separately measure O2 uptake during ventilatory bouts and apneic periods using a flow-through metabolic chamber with a small dead space volume and short time constant. Oxygen uptake was measured during apneas ranging from 10 to 150 min duration at body temperatures of 20, 10 and 5 degrees C. The fraction of total O2… CONTINUE READING
