  body temperature. The Columbia Encyclopedia, Sixth Edition. 2001-05
Temperature regulatory mechanisms act through the autonomic nervous system and are largely controlled by the hypothalamus of the brain, which responds to stimuli from nerve receptors in the skin.
Fever, caused by a resetting of the temperature regulatory mechanism, is a response to fever-causing, or pyrogenic, substances, such as bacterial endotoxins or leucocyte extracts.
The body temperature of fishes must remain close to that of the surrounding water, because heat is lost directly into the water during respiration; however, in some fishes, such as the bluefin tuna, a special network of fine veins and arteries called the rete mirabile provides a thermal barrier against loss of metabolic heat.

  Temperature - Wikipedia, the free encyclopedia
Temperature arises from the random microscopic motions of the atomic and subatomic constituents of matter, where temperature is related to the average energy of these microscopic motions.
Temperature is measured with thermometers that may be calibrated to a variety of temperature scales.

The diurnal temperature curve follows the periods of rest and activity, and is not dependent on the incidence of day and night; in monkeys which are active during the night and resting during the day, the body temperature is highest at night and lowest through the day.
They found that in nocturnal birds the temperature is highest during the natural period of activity (night) and lowest during the period of rest (day), but that the mean temperature is lower and the range less than in diurnal birds of the same size.

 Basal Body Temperature
Basal body temperature is the temperature of your body at rest.
Your body temperature rises by a small amount (0.5 to 1.0 degree Fahrenheit) at the time of ovulation, and then stays elevated for several days, due to the rise in the level of the hormone progesterone.
If you use a basal body temperature, which typically marks the units from 96 to 100 degrees with markings for each one-tenth of a degree, rather than an ordinary thermometer, it will be easier for you to distinguish the minor temperature fluctuations associated with ovulation.

 Reduced body temperature extends lifespan in study from the Scripps Research Institute
Prior to this study, researchers had known that core body temperature and aging were related in cold-blooded animals.
