[Changes in the internal temperature and the cardiac rhythm of the Saharian lizard, Varanus griseus Daud., using radiotelemetry].
The evolution of the internal temperature and of the heart rate, recorded by telemetry, has been studied on Varanus griseus, by using  transmitters of reduced size, in the natural conditions of Sahara. A parallelism between these two parameters exists. However, an anticipation of the heart rate increase during sun basking has been established. The hearing and cooling dynamics have been specified; a hypothesis on the mechanism of winter dormancy entrance has been proposed.
