Abstract : The effect of body warming and cooling on the heart and breathing rates has been studied in the agamid lizard Uromastyx mi- crolipes. Electrocardiograph (ECG) of Uromastyx microlipes consists of P, QRS, and T components similar to those in mammals. Heart rate increases with body temperature. During warming the heart rate ranged from 7-134 beat/min, while during cooling ranged from 2-73 beat/min. The mean of heart rate during warming and cooling was not significantly different except at body temperatures of 20?C and 35?C. In two lizards heart rate was higher during warming than cooling for all temperatures. Both breathing types (thoracic and buccal) increased in frequency with body temperature. The range of thoracic breathing rates during both warming and cooling was 0-20 breath/min. Buccal breathing rate was 0-24 breath/min during warming, and 0-26 breath/ min during cooling.
