Size-invariant exercise-induced aerobic scope across a broad body mass range in a giant isopod

Aerobic scope is the aerobic metabolism left after maintenance costs are met, and it sets a simple limit on how much oxygen-dependent activity an animal can support.

Aerobic scope is the aerobic metabolism left after maintenance costs are met, and it sets a simple limit on how much oxygen-dependent activity an animal can support. In many aquatic animals, this margin changes with body size because resting and active metabolic rates do not…
