dc.description.abstract Exposure of newts, Notophthalmus viridescens, to whole body gamma irradiation increased their resistance to high temperatures. The effect increased progressively with increasing exposure from 250 to 2000 r. In the aquatic adult stage of the life cycle, irradiation had its greatest effect on the critical thermal maximum, while the terrestrial sub-adult efts showed greater change in the appearance of the first signs of distress. Dehydration of adult newts increased temperature resistance slightly; dehydration combined with irradiation had a greater effect than the sum of their separate effects. Free radicals and related compounds are apparently involved in heat death in amphibians. en_US
