    Abstract

    1. 1. There were no systematic differences in routine metabolic rates between the two species. 2. 2. Only temperature significantly affected these rates, with thermal acclimation having no significant effect. Major discontinuities in metabolic rate-temperature curves were found at 15 and 35 °C. Rates were relatively insensitive to temperature in the intervals 5 to 10°C and 15 to 30°C. 3. 3. There were no differences of rates determined in two successive breeding seasons, nor between the sexes. 4. 4. Metabolism is related to body weight in the form of an allometric equation; the exponent is 0.656. 5. 5. Patterns and rates of Ranidella are consistent with the trends reported for northern hemisphere temperate anurans.
