Question: What is the effect of population dynamics on the evolutionarily optimal life history with metabolic (allometric) production constraints?
Mathematical methods: Optimization of a phenotype’s intrinsic rate of increase r with respect to adult mass, mα.
Results: The change in optimal adult size (mα) between growing (r > 0) and stable (r = 0) populations is hard to predict, but reproductive effort (and lifetime reproductive effort) in the growing population is predicted to be 1 + r · E times larger, where E is the average adult life span.
Keywords: allometry, dimensionless, metabolic ecology, norm-of-reaction, r-/k-selection.
