Examples of physiological modes of action in DEB, where s stands for a stress factor(s) that modifies the value of a metabolic parameter

Mode of action	Affected parameter(s)
Decrease of ingestion rate	f → f (1 − s)
Increase in somatic maintenance	k M → k M (1 + s)
Increase in maturity maintenance	k J → k J (1 + s)
Increase in costs for structure (growth)	g → g (1 + s) and k M → k M/(1 + s)
Increase in reproduction costs	κ R → κ R/(1 + s)
Hazard to the developing embryo	κ R → κ R exp(−s)
Change in allocation	κ → κ (1 ± s) and g → g/(1 ± s)
