1. Comparative Vertebrate Physiology
Metabolism

2. Metabolism Anabolism plus catabolism Measurement Basal metabolic rate
Standard metabolic rate
Field metabolic rate

3. Measurement Direct calorimetry
Measurement of food intake and waste excretion

4. Measurement Indirect calorimetry
Measurement of O2 utilization (must know the diet of the animal due to R.Q.)

5. Respiratory quotient
Carbohydrates
Lipids (tripalmitin)

6. Factors effecting metabolism
Food availability (> 30 days)
Long term starvation (brooding, wintering)

7. Factors effecting metabolism
Food availability
Short term starvation (30 days)

8. Factors effecting metabolism
Thermy
Greatest variation during torpor
Oxygen consumption (ml/g/hr)
Ambient temperature (°C)
Ambient temperature (°C)

9. Factors effecting metabolism
Activity (greatest factor)

10. Factors effecting metabolism
Body size

11. Factors effecting metabolism
Relationship between metabolic rate and body mass
Y = a massb
a: intercept, b: slope

12. Factors effecting metabolism
