Constraints of bioenergetics on the ecology and distribution of vertebrate ectotherms. Final report, 1 September 1988--30 June 1990
The constraints of bioenergetics on the ecology and distribution of vertebrate ectotherms were quantified. During this project we conducted studies: to determine the role of incubation temperature on the post-hatching growth rate of the snapping turtle, Chelydra serpentina; to establish the rate of energy expenditure of the slider turtle, Trachemys scripta, in the field; to determine the field metabolic rates, body temperatures and selected microclimates of the box turtle, Terrapene carolina, and to measure the effect of diet type on the consumption rate, digestion rate and digestive efficiency of adult T. scripta. We also completed our research on the three-dimensional bioenergetic climate space for freshwater turtles.
