The oxygen consumption and total body lactate concentration of specimens of the terrestrial salamander Plethodon jordani were measured at rest and after 5 min of forced locomotion, at full hydration (100% of standard body mass) and after dehydration to 85% of standard mass, at 15 and 25 degree C. In addition, the authors measured standard and activity oxygen consumption of specimens of newts, Notophthalmus viridescens , in their terrestrial stage (efts), at 100% and 80% of standard mass, at 15 degree C. Dehydration had no effect on the oxygen consumption of these salamanders at rest or during induced activity. Furthermore, dehydration elicited no change in the resting or post-activity lactate concentration.
