Abstract

The effect of temperature on electrolyte metabolism in the lizard Cnemidophorus perplexus was studied. The biological half-time and tissue distribution were the aspects of cesium and sodium metabolism noted. Increased temperature results in a higher metabolic rate. Measurements were made of the extent oxygen consumption increased with raised temperature in C. perplexus. Radioisotopes sodium-22 and cesium-137 were injected intraperitoneally into lizards kept at several environmental temperatures. Whole body radioactivity counts were taken twice daily on the live animals to determine the retention curves. At 50% retention and 80% retention lizards were sacrificed and tissue radioactivity counts taken to determine electrolyte distribution. Sodium and cesium are excreted more rapidly at higher metabolic rates. The increased metabolic rates do not affect tissue distribution.
