ANT211H5 Lecture Notes - Lecture 6: Semelparity And Iteroparity, Infant Mortality, List Of Mammalian Gestation Durations
Document Summary
Ant211 sex roles & parental care: life history strategies. How an organism allocates its efforts over its lifetime in order to maximize fitness. Unique qualities of human life history strategy from the hill and caplin reading. Giving so much energy for finance, clothing, etc ; allocation of resources and energy for different aspects in order to maximize its fitness. 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. All of the reproductive strategies into the reproductive event. Example: preying mentee male giving up his life for female during copulation- semelparity. Iteroparity: go to a pre-reproductive state where female begins to ovulate again. 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. Allocation over your entire reproductive life- there are other elements of energy allocation.
