Document Summary
Effect of temperature on oxygen consumption of the mouse, Thermoregulation is a trait used by endothermic homeotherms to maintain constant body temperature through metabolic rate and heat regulation. Mus domesticus using a scholander respirometer to help determine the thermoneutral zone (tnz) and lower critical temperature (lct), hypothesizing that 10 c and 30 c temperatures were outside of its tnz. Its mean mass was 26. 15g and it was treated with temperatures of. Significance in o2 consumption rates was seen comparing room treatments to warm and cold treatment groups (p<0. 001) with no significance between the later two rates (p= 0. 148). These results supported our hypothesis while demonstrating the ability of thermoregulation in m. domesticus when exposed to stressful temperatures outside of its tnz. Endothermic homeotherms posses the physiological trait of thermoregulation that allows for them to maintain relatively stable body temperature across varying ranges of ambient temperature.
