title: Oxygen consumption in the tortoise, Testudo hermanni G., subjected to sudden temperature changes in summer and autumn.
abstract: A respirometer for long-term measurements of oxygen consumption in terrestrial vertebrates is described. The tortoise, Testudo hermanni Gmelin, investigated in summer and autumn, presents a day-night rhythm of oxygen consumption at 28 and 18 degrees C but not at 8 degrees C. The standard metabolic rate presents an important and constant thermal dependence in the range 8-18-28 degrees C.
