“…1). These results have been presented by Terpin (1976) and will be discussed at three meetings this summer (list of scientific presentations attached). Our analysis indicates that the steady state energy budget model ) is an accurate and precise tool for the prediction of equilibrium body temperatures of alligators (Fig.…”

“…After completing our heat transfer analysis of the alligator (Terpin et al 1979) we found that the evaporative water loss process required further clarification. While a small component of an alligator's energy budget, evaporative water loss could be important in terms of its osmoregulatory ability.…”

A time dependent mathematical model accurately predicts heart, brain and gut temperatures of largemouth bass, Micropterus salmoides. Body diameter, insulation thickness, and tissue thermal conductivity are controlling variables in•the transfer of heat between a fish and water. Fish metabolic rate and water velocity across fish surfaces do not appreciably affect heat transfer rates. These results are confirmed by laboratory experiments on live fish. Field experiments are now beginning to test the model. Multichannel temperature transmitters telemeter body temperatures of free swimming bass in Pond C on the Savannah River Plant while the behavior of those fish and other bass is recorded by an observer in an 8 m high tower.-Field studies of the home ranges and movements of turtles, Chrysemys scripta, in Par Pond on the Savannah River Plant are completed. We have marked and released over 400 turtles captured during 178,000 trap hours. We have recorded the movements of 30 individuals fitted with radio transmitters. Distinct differences are apparent in the behavior of turtles in areas affected by heated effluents as compared to those in control areas. Calculations and theoretical analysis of the transient energy exchange of £. scripta are continuing. We are now in the final .stages of analyzing field and laboratory data. This fall we will begin writing our definitive paper on the behavioral thermoregulatory mechanisms of C. scripta. and skin of alligators, Alligator mississippiensis, increases 2 to 6 fold dur-133 Laboratory experiments using Xe indicate that blood flow in the muscles ing movement.
