Cardiorespiratory responses of the woodchuck and porcupine to CO2 and hypoxia

Abstract

The burrow-dwelling woodchuck (Marmota monax) (mean body wt.=4.45±1 kg) was compared to a similar-sized (5.87±1.5 kg) but arboreal rodent, the porcupine (Erithrizon dorsatum), in terms of its ventilatory and heart rate responses to hypoxia and hypercapnia, and its blood characteristics.V T,f,T I andT E were measured by whole-body plethysmography in four… (More)
