The cardiodynamic consequences of dry season dormancy in ectothermic vertebrates is not well known. Our hypothesis was that dormancy would reduce cardiac activity. We therefore determined oxygen uptake and cardiovascular function in aestivating toads, Bufo paracnemis, native to SΓ£o Paulo State, Braz
## Abstract Resting plasma epinephrine (E) and norepinephrine (N) concentrations for intact toads (__Bufo paracnemis__) were 5.57Β±1.0 and 0.88Β±0.38 ng/ml, respectively. Exercise induced a significant increase in heart rate, blood pressure and plasma epinephrine (about 4.3 times), whereas norepineph
