The goal of this research was to conduct the mass-specific (MRMS) metabolic rate (oxygen consumption) for homeothermic endothermic female mice (Mus musculus) depending on their body mass and temperature of their environment. Mice were first weighed and then placed into 250mL chambers. The aquatic environments surrounding the chambers were acclimated to temperatures of 10°C, 15°C, 20°C, 25°C and 30°C. The effects of temperature and mass on metabolic rate of the female mice were measured by monitoring the oxygen consumption in a specific time interval, using static respirometry. The data for several different groups was then collected and the least square linear regression from a log mass-log MRMS plot at 30°C, yielded a slope of. At 10°C, majority of the mice exhibited the highest metabolic rates. At 10°C, the mean MRMS was. The final results for this experiment depicted that body mass of an organism and the temperature it is in has an effect on its metabolic rate.

This mice is usually bred as a mutant type considering the sparse way of catching it in nature. Being a furred mammal, it has hair all over at different lengths and fibers to aid in keeping a sustainable environment (Dry 1926). Most of the adaptive thermoregulation in a mouse takes place in brown adipose tissue (Gray et al. 2002). This rodent is an endotherm. Endotherms are known for maintaining a constant, within narrow range, internal environment, unrelatedly to their external environment. That is opposite of an ectotherm which changes its internal environment temperature to match it external surrounding environment (Cannon 2011). And at any condition, especially standard laboratory conditions, the correlation between metabolic rate versus temperature and body size are negative (Kleiber
