Document Summary
Sex roles & parental care: life history strategies. How an organism allocates its efforts over its lifetime in order to maximize fitness: optimize energy over lifetime. Iteroparity: repeated reproduction, return to pre-reproductive state, expend energy over time (reproductive lifetime) Budget energy between reproductive effort & somatic effort (divided into growth & maintenance) Allocation of resources between body size & reproduction. How large an organism should grow before reproduction. A sex difference in the age of first reproduction (may be either sex that matures first) R selected species: adapted for natural selection to maximize population growth, prolific breeders will win the largest share of the gene pool, born quite immature. Characteristics of the 2 strategies may not have anything to do with fluctuating environment. There is a limited generality of the strategies themselves. K is a composite of population, resources and their interaction,
