Document Summary
Whole chapter basically on two researches, emlen and oring. Mating system: a description of the social associations and number of sexual partners and individual has during one breeding season. One mating system model says the systems can be understood by looking at two factors: Evolutionary: sexual conflict, or the differential selection on males and females to maximize their fitness. (competing interests of the sexes in attempt to maximize their fitness) Ecological: the ways in which resource limitation and distribution affect the fitness benefits and costs for each sex. Female will usually be more strongly limited by resource. Energy invested in producing egg and parental care. Male will be limited by number of sexual partners he obtains. Females may do monogamy or polyandry depending on males. No sexual conflict, poor resources, high predation when baby is young all lead to monogamy. May aggregate to decrease predation risk, or avoid harassment from males.
