Study Notes
Isometric Scaling of Metabolic Rate
- Metabolic rate generally increases with mass.
- Larger mass typically corresponds to a higher metabolic rate.
- If you take a chunk of mass from each animal and measure its metabolic rate, it would be the same.
Allometric Scaling of Metabolic Rate
- Larger animals exhibit slower metabolic rates in relation to their size.
- Metabolic rate per unit of mass decreases as the animal's size increases.
Scaling Exponent
- Metabolic rate scaling is non-linear.
- Equations exist to mathematically express the relationship (provided).
- Scaling exponents are different for different processes or states – basal metabolic rate (BMR) vs. maximum oxygen uptake (VO2max).
Kleiber's Law
- Animal's metabolic rate scales to the 3/4 power of its mass.
- A scaling exponent of approximately 0.75 is often seen across animal species.
- Differences in scaling exponents exist between groups and activities; the reasons are not yet established.
