ANT211H5 Lecture Notes - Lecture 6: Semelparity And Iteroparity, List Of Mammalian Gestation Durations, Statistical Parameter
Document Summary
Ant211 sex roles & parental care: life history strategies. How an organism allocates its eforts over its lifetime in order to maximize itness. Semelparity: expending one"s resources & dying in a single reproductive effort, common among plants (e. g. annuals) Iteroparity: repeated reproduction, return to pre-reproductive state. Budget energy between reproductive efort & somatic efort (divided into growth & maintenance) Allocation of resources between body size & reproduction. How large an organism should grow before reproduction. A sex diference in the age of irst reproduction (may be either sex that matures irst) 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 i. e. carrying capacity of habitat. R selected species: adapted for natural selection to maximize population growth, proliic breeders will win the largest share of the gene pool.
