Henry J Harlow, Mark Hoffman, and Stanley S Hillman, The effect of temperature on digestive efficiency in the herbivorous lizard, Dipsosaurus dorsalis: .

Summary

1. There is a significant correlation between body temperatures of the lizardDipsosaurus dorsalis and the proportion of ingested food utilized. 2. At temperatures of 33, 37, and 41° C apparent digestibility coefficients (ADC) were 54.3%, 62.8% and 69.5% respectively. Lizards kept at 28° C did not pass food beyond the stomach and died, while lizards cycled between 28° C and 41° C had an ADC predicted for the mean of those temperatures. 3. When corrected for fibrous material, these values became 70%, 82% and 89% which agree well with other herbivorous lizards on a low fiber diet. 4. Field passage rates of lizards fed markers correspond to recorded laboratory passage time of two to three days. 5. The data indicate that thermoregulation [...]
