Mammal life-history evolution with size-dependent mortality
Eric L. Charnov*
Department of Biology, The University of New Mexico, Albuquerque, NM 87131-0001, USA
Question: What is the effect of within-species size dependence of mortality on the between-species allometries for maturation and adult life span?
Mathematical methods: Optimization of net-reproductive rate, R0, with respect to adult mass, mα.
Key assumptions: Instantaneous mortality at age x, size mx, is proportional to mx−h, and this assumption is added to the Charnov (2001) mammal life-history model.
Results: h in the range of zero to 0.20 has a very small (≈ 10–15%) effect on the heights of the allometries.
Keywords: allometry, life span, maturation, optimization, sensitivity analysis.
