✦ Synopsis

Numerous scattered reports have given data on effects of temperature upon heart rates in reptiles. Reports have also been made on rates of oxygen consumption at different temperatures. However, few (with the exception of Adolph, '51) have attempted to correlate these phenomena even though Benedict, in his extensive study of reptile physiology ('32), has stated he believed that ''. . . the heart rate of the tortoise may furnish a significant hint as to its metabolic activity." Also, the size of the animals has usually not been considered in interpreting the data reported.

It was the purpose of this investigation to attempt to determine the effects of temperature and body size upon heart rate and metabolic rate in two species of turtles, and to determine if a correlation exists between heart rate and metabolic rate in these animals.

Oxygen consumption rates were measured in a respirometer for different mammalian cell lines (BHK, murine hybridoma, and CHO), and the effects of cell density (1-20 million cells/mL) and temperature (6 to 37°C) on specific oxygen consumption rate were investigated. The specific oxygen consumption was

## Abstract Different species of earthworms show distinct patterns of oxygen consumption pattern. __Amynthas gracilis__ has a diurnal rhythm of oxygen consumption, consuming more oxygen at night, whether being incubated at 20, 25, or 30°C. The higher oxygen consumption of __A. gracilis__ is directl
