| Abstract |
|
Testudinidae Seasonal effects were determined on the metabolic rate of adult Chersina angulata. Summer experiments were conducted in summer and winter experiments conducted in winter. The tortoises were acclimated to standard summer and winter conditions in an environmentally controlled room prior to experiments. Oxygen consumption (VO2) was measured as an index of metabolic rate at experimental temperatures of 14°C, 18°C and 22°C. In addition, VO2 of winter–acclimated tortoises was measured at 10°C. The metabolic rate for both winter–acclimated and summer–acclimated tortoises increased significantly with increasing experimental temperature within the temperature range tested. Season had no statistically significant effect on the metabolic rate of C. angulata. The metabolic rate–temperature curves of the summer–acclimated and the winter– acclimated tortoises cross each other.
