Influence of a broad temperature range on the oxygen consumption rates of three desert lizard species

Oxygen consumption rates of three desert lizard species: (Acanthodactylus boskianus, Lacertidae; Scincus mitranus, Scincidae; Diplometopon zarudnyi, Amphisbaenidae) were determined in relation to ambient temperatures ranging from 10 to 35 degrees C using a double-chamber, volumetric closed system. The interspecific differences in the oxygen consumption rates were found to have a close relationship between the characteristics of the M-T curves, the thermoregulatory behaviour and the ecology of the respective species. The M-T curves of the studied lizards were specifically modified and adjusted to their climatic region.
