MATERNAL, PATERNAL, & ALLOPARENTAL CARE IN MARMOSETS

目标：通过以下方式评估对父母努力的贡献 母亲、父亲和年长的兄弟姐妹，并发现潜力 这些变化的内分泌和经验决定因素 模式。结果通过使用灵长类中心核心试验 服务和设施，我们能够完成初步的 猴尿催乳素检测方法的验证，提示 这个化验可能有助于我们评估这一作用 脑垂体肽在调节父母照料中的作用。此外，我们还展示了 这个群体的人口学特征影响着父母的照料模式 方式。兄弟姐妹“帮手”的存在减少了父亲的努力， 但对母亲的努力程度没有影响。我们的未来方向 将通过不同的方式评估父母照顾的差异程度 组成员与个体在以下方面的水平差异相关 脑垂体肽和性激素水平。关键词 催乳素、雌激素、孕酮、尿激素

OBJECTIVE: To evaluate contributions to parental effort by mothers, fathers, and older siblings, and to identify potential endocrine and experiential determinant of variability in these patterns. RESULTS Through the use of the Primate Center core assay services and facilities, we were able to complete an initial validation of an assay for marmoset urinary prolactin, suggesting that the assay may be useful for helping us assess the role of this pituitary peptide in regulating parental care. Further, we have shown that group demography affects patterns of parental care in intriguing ways. The presence of sibling "helpers" reduces effort by the father, but has not effect on levels of maternal effort. FUTURE DIRECTIONS We will assess the degree to which variation in parental care by various group members is associated with individual differences in levels of pituitary peptide and sex steroid hormone concentrations. KEY WORDS Prolactin, estrogen, progesterone, urinary hormones
