Amount of Parental Investment

چکیده
It is a common assumption in evolutionary theory that a parent will distribute its resources evenly between a set of equivalent oospring. However this paper presents a theoretical model in which uneven parental investment between a set of equivalent oospring can be a preferred evolutionary strategy to equal investment in the same set of oospring. This eeect does not depend on different oospring having diierent survival probabilities. It is further shown that this same behavior could still arise when changes in the size of each clutch of oospring are taken into account.

Parental Care and Investment
Parental care is common throughout the animal kingdom and among caring species there is a bewildering variation in how parents care for offspring, as well as in the amount of resources parents invest in care. For instance, there is considerable variation in the relative parental investment by the sexes – in some species females invest more, in others males invest more, and in some investment is...
متن کاملSex differences in parental care: Gametic investment, sexual selection, and social environment.
Male and female parents often provide different type and amount of care to their offspring. Three major drivers have been proposed to explain parental sex roles: (1) differential gametic investment by males and females that precipitates into sex difference in care, (2) different intensity of sexual selection acting on males and females, and (3) biased social environment that facilitates the mor...
متن کاملDynamic adjustment of parental care in response to perceived paternity.
Theories of parental care evolution predict that genetic relatedness will be an important variable in the amount of care a parent provides. However, current inferences of relatedness-based parental investment from studies in humans and birds remain challenged. No study has yet demonstrated parental care adjustment in a manner uncomplicated by life-history correlates or experimental design. We n...
متن کاملParental investment in couples who conceived spontaneously or with assisted reproductive techniques.
BACKGROUND It has been suggested that couples who conceive with assisted reproductive technologies (ART) invest more in their child than those who conceive spontaneously. This study examined how parental investment in the child (PIC) varied as a function of method-of-conception, gender and other contextual variables, i.e. prenatal depression, social support and satisfaction with the marital rel...
متن کاملBegging for control : when are offspring solicitation behaviours honest ?
Geoff A. Parker Population and Evolutionary Biology Research Group, Nicholson Building, School of Biological Sciences, University of Liverpool, Liverpool, UK L69 3GS. Ever since Trivers [1] showed that parents and their offspring could be in conflict over the amount of parental investment, the evolution and maintenance of begging behaviour has been an area of increasing interest to evolutionary...
