Tegu Lizard Temperature
Can tegu lizards maintain an elevated body temperature during their reproductive season?
Experiment:
Dr. Glenn Tattersall and a team of researchers in Rio Claro, Brazil studied changes in the heart rate and body temperature of tegu lizards (Salvator merianae), by implanting lizards bred in captivity with specialized electronic chips. One group of lizard lived in an entirely outdoor environment for one year. Three other groups that were subjected to alternating indoor and outdoor environments over the course of three reproductive seasons. These last three groups were also subject to varying ambient temperature, amounts of light, and amounts time spent in and out of doors.
Result:
For most of the year tegu lizards retained a body temperature
