Terminal investment and senescence in rhesus macaques (Macaca mulatta) on Cayo Santiago.
Long-lived iteroparous species often show aging-related changes in reproduction that may be explained by 2 non-mutually exclusive hypotheses. The terminal investment hypothesis predicts increased female reproductive effort toward the end of the life span, as individuals have little to gain by reserving effort for the future. The senescence hypothesis predicts decreased female reproductive outpu...
متن کاملMaternal Dominance Rank and Age Affect Offspring Sex Ratio in Pigtail Macaques
This study tested some predictions of the local-resource-competition hypothesis and localresource-enhancement hypothesis of sex-biased maternal investment in a population of pigtail macaques (Macaca nemestrina leonina). Offspring sex ratios in highand lowranking matrilines were biased in opposite directions as predicted. Sex ratio in the middleranking matriline was female biased similar to the ...
متن کاملFemale rhesus macaques discriminate unfamiliar paternal sisters in playback experiments: support for acoustic phenotype matching.
Widespread evidence exists that when relatives live together, kinship plays a central role in shaping the evolution of social behaviour. Previous studies showed that female rhesus macaques (Macaca mulatta) recognize familiar maternal kin using vocal cues. Recognizing paternal kin might, however, be more difficult as rhesus females mate promiscuously during the possible conception period, most p...
متن کاملOffspring of primiparous mothers do not experience greater mortality or poorer growth: Revisiting the conventional wisdom with archival records of Rhesus Macaques.
Female mammals often begin to reproduce before achieving somatic maturity and therefore face tradeoffs between allocating energy to reproduction or their own continued development. Constraints on primiparous females are associated with greater reproductive failure, and first-born infants often have slower growth and greater mortality and morbidity than infants born to multiparous females. Effec...
متن کاملPaternal relatedness and age proximity regulate social relationships among adult female rhesus macaques.
Kin selection promotes the evolution of social behavior that increases the survival and reproductive success of close relatives. Among primates, maternal kinship frequently coincides with a higher frequency of grooming and agonistic aiding, but the extent to which paternal kinship influences adult female social relationships has not yet been investigated. Here, we examine the effect of both mat...
