  pages={694 - 695}
At varying environmental temperatures, measurements of body temperatures and gas exchange of a female Indian python (Python molurus bivittatus) show that during the brooding period this animal can regulate its body temperature by physiological means analogous to those in endotherms. Ambient temperatures below 33�C result in spasmodic contractions of the body musculature with a consequent increase in metabolism and body temperature. 
Thermoregulation by a Brooding Burmese Python (Python Molurus Bivittatus) in Florida
This observation of thermoregulation through shivering thermogenesis and clutch insulation by a brooding Python molurus bivittatus (Burmese Python) just outside the northern boundary of Everglades National Park, FL is the first documented instance of a Burm Myanmar Python exhibiting this behavior in the wild.

Reptilian endothermy: a field study of thermoregulation by brooding diamond pythons
Miniature temperature-sensitive radiotransmitters were surgically implanted into free-ranging adult diamond pythons (Morelia s. spilota), which are medium-sized boid snakes of south-eastern Australia, and the snakes maintained high and relatively constant body temperatures throughout the two-month incubation period.

Carpet pythons were subjected to various conditions of substrate and shelter and their behavior observed and correlated with body temperature measured by radio telemetry and values near the mean preferred temperature were maintained by basking and postural changes. Expand
Thermophilic response to feeding of the diamond python, Morelia S. spilota (Serpentes: Boidae)
Pythons without access to a heat source showed no elevation in body temperature after feeding, indicating that the thermophilic response to feeding in this species is achieved behaviorally, not physiologically. Expand
Thermogenesis could play a role in the thermal ecology and habitat selection of macroteiid lizards and proper- ties of whiptail lizards are similar to but much greater than those of varanidLizards. Expand
Behavioral Thermoregulation in Australian Elapid Snakes
Thermoregulation in laboratory thermal gradients was studied in seven species of Australian snakes of the Elapidae and all species exhibited well-developed thermoregulatory behavior and controlled body temperatures with precision comparable to that reported for various heliothermic lizards. Expand
Further Observations on Thermoregulation in the Brooding Female Python molurus bivittatus (Serpentes: Boidae)
Standard metabolic rate of the non-gravid animal increased with temperature, but not in a simple, exponential fashion. Expand
Revisiting Python Thermogenesis: Brooding Burmese Pythons (Python bivittatus) Cue on Body, not Clutch, Temperature
The results confirm general patterns of facultative thermogenesis reported previously and strongly suggest that females use core body temperature to regulate their thermogenic activity. Expand
Evolution: A lizard that generates heat
The discovery of endothermy during the reproductive period of a tegu lizard sheds light on the evolution of this characteristic. Expand
Thermal biology of large snakes in cool climates: a radio-telemetric study of carpet pythons (Morelia spilota imbricata) in south-western Australia
Radio-telemetric monitoring of 70 free-ranging carpet pythons at two sites in southwestern Australia provided extensive data on the body temperatures exhibited by these animals, finding females wrapped tightly around their eggs after oviposition and brooded them throughout the ensuing 8-week incubation period, and overall maintained lower and more variable incubation temperatures.

Shivering and Heat Production in Wild Birds
In winter in the north during the daylight hours, birds move about in search of food and general muscular activity produces sufficient heat to maintain body temperature, but at times of inactivity during the day or especially at night when birds are inactive, increased muscle tone and shivering appear to be the only methods available for producing heat.

During the winter, wild rats (Rattus norwegicus) develop metabolic adjustments similar to those found in the white rats acclimated to cold in the laboratory, suggesting that non-shivering metabolism in these wild rats, as in the case of white rats, is mediated by noradrenaline. Expand

To the authors' knowledge this is the first demonstration of non-shivering heat regulation of this magnitude and it is suggested that this regulation results from the release of adrenal and extra-adrenal epinephrine and that the increased heat production by cold-adapted animals results from an increased epine cortisol sensitivity.
