Document Summary
In a case where compensation occurs, the shape of the response curve is modified: both curves are showing q10. In this case, the organism is maintaining the same metabolic rate year round by compensating shifting the curve: acute perturbations can come from mismatches in pathways.

How can compensation work: change enzymes in a pathway. Hwa chapter 1: animals and environments function on the ecological stage (pp.
