IMPORTANCE OF PATERNAL CARE

该子项目是利用NIH/NCRR资助的中心赠款提供的资源的许多研究子项目之一。子项目和研究者（PI）可能从另一个NIH来源获得主要资金，因此可以在其他CRISP条目中表示。所列机构为中心，不一定是研究者所在机构。确定灵长类动物良好养育的促进因素。 与人类一样，合作繁殖的绒猴和绢毛猴也表现出相当数量的父亲指导的婴儿护理。然而，绒猴和绢毛猴的父亲比母亲花更多的时间照顾婴儿。我们发现，父亲在分娩前表现出荷尔蒙的变化，促进婴儿的反应。这两个物种的准父亲在配偶怀孕期间体重增加。雄性的体重增加在其配偶出现明显的体重变化之前就开始了。我们认为这些体重变化与雄性荷尔蒙的变化有关。体重的变化可能是由于抵消了照顾出生后的婴儿的能量成本。本研究使用WNPRC Assay Services。

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. To determine the facilitators of good parenting in primates. As in humans, cooperative breeding marmosets and tamarins show a considerable amount of father directed infant care. However, marmoset and tamarin fathers spend more time than the mother caring for infants. We found that fathers before delivery show hormonal changes that facilitate infant responsiveness. Expectant fathers of both species show an increase in body weight during their mate¿s pregnancy. Male onset in weight gain begins before their mate shows noticeable weight changes. We think these weight changes are associated with the changes in hormones in the males. The weight changes may be due to offset the energetic costs of caring for infants following birth. This research used WNPRC Assay Services.
