Heat Resistance of Some Australian Lizards

Survival times of Australian lizards representing 29 species of 16 genera in the Agamidae, Scincidae, Gekkonidae, and Pygopodidae, were determined at a series of high temperatures in the range in which this function shows strong thermal dependence. Most species were studied at 40.5?, 43.5?, and 46? C, but this range was expanded to include 37.5? or 47? C for a few. Results indicate some differences in heat resistance between
