N.  aPhysiological theruregulation of mature alligators.  c1984  a1. A 67.1 kg alligator (Alligator mississippiensis), tested in air, heated twice as fast as it cooled. The cooling thermal time constant was 425 min while alive. Warming and cooling thermal time constant were 421 min after death. The thermal time constant was not appropriate in describing warming in air of mature alligators. 2. Surface and subdermal heat flow measurements of the 67.1 kg animal indicate greather blood flow in the skin during warming compared to cooling. 3. Two mature alligators, 49.9 and 103 kg, were heated and cooled in water. Warming time constants were 67 and 116 min respectively. Cooling time constyants were 180 and 246 min. 4. Data from this study were combined with previously published thermal ime constants for alligators providing regression equations for alligators ranging from 37 to 103 kg. Regression equations for alligators teste in water. 5. Thermal conductance and metabolism data are combined to provide an estimate of the amount the body temperature of theoretical alligators ranging from 50 g to 1000 kg would be elevated by metabolism. A body temperature of 34.2C is predicted for a 1000 kg theoretical alligator in 30C water.  aphysiology  awildlife  aCrocodilo  aFisiologia  aJacaré  aAnimal silvestre1 aSTANDORA, E.
