ANT211H5 Lecture Notes - Lecture 6: Menopause, Weaning, Chromosome
Document Summary
Ant211 - sex roles & parental care: life. How an organism allocates its efforts over its lifetime in order to maximize fitness. Expending one"s resources & dying in a single reproductive effort. Budget energy between reproductive effort & somatic effort (divided into growth & maintenance) 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: a measure of the intrinsic rate of increase of the size of a population free from resource limitations. K: the maximum population that a species can maintain in a particular habitat. Adapted for natural selection to maximize population growth. Prolific breeders will win the largest share of the gene pool. Population is at near maximum that habitat can support. Selection toward stable population size efficient use of resources. Characteristics of the 2 strategies may not have anything to do with fluctuating environment.
