Question

Calculate the expected resting metabolic rate (VO2) in mL O2 H^-1 for a 200g thirteenlined ground squirrel using the following allometric equation. Calculate the expected resting metabolic rate (V02) in mL 02 h 1 tor a 2QQ g thirteen-lined ground squirrel using the following allomctric equation. VO2 = 4. 24mass^0. 72 Assuming the average resting metabolic rate for Wisconsin thirteen-lined ground squirrels is equal to your oxygen consumption value from #1 above, how close does this fit your allometrically predicted value from #2 above. Use the following equation to calculate this. % delta V02 - VO2observed / V02predicted Times100 Calculate allometrically predicted thermal conductance for a 200 g thirteen-lined ground squirrel using the following equation. C = 1. 10 mass0 50 This gives thermal conductance in units of ml 02 h^-1 degree C^-1 Energetic Savings from Torpor The simplified model of heat balance in endotherms can be used to predict oxygen consumption for normothermic ground squirrels with a body temperature of 37degree C. V02 = C(Tb-Ta) Compute predicted oxygen consumption using allometrically predicted C from number 4. a body temperature of 37degree C, and the air temperature of 0degree C . If a thirteen-lined ground squirrel is using torpor at 0degree C, the average oxygen consumption has been recorded to be 70 mL 02 h^-1. Compare this value with your predicted from number 5 above to estimate energetic savings due to torpor. Use equation (2) above to compare observed (70 mL 02 h^-1) with predicted from number 5.

Explanation / Answer

Resting metabolic rate is ml oxygen consumed per hr * weight in kg

As given in the qs, equation is

Therefore, Expected Resting metabolic rate = 4.24 * (0.2)0.72 = 1.33 ml O2/kg/hr.
