Rhesus Maternal Care in Relation to Population Growth, Awardin U.S. and Indian Currencies

描述：本项目支持约翰逊博士 和一位印度科学家在恒河猴身上进行的研究， 博士（夫人）Iqbal Malik，家政学研究所， 印度德里大学。 他们计划研究 母亲的投资行为，并寻求确定 生态和社会因素，造成的变化， 婴儿哺乳期的长短和频率。 将特别注意两个因素： 时间预算和可获得的固体食物的供应 给年幼的婴儿。 目前的预测是， 允许婴儿更频繁地哺乳或更长时间的延迟 繁殖周期，从而使这些年轻人， 在它们断奶的时候会相对变老。 这是 基于人类母亲的假设， 频繁的护理与 持续时间短，哺乳期延长 不孕 这项研究将在两个出生 季节通过观察恒河猴在自然 印度的自由放养人口。 范围：这两位科学家过去曾在以下方面合作： 在这个领域的研究。 建议的工作是及时的， 有可能产生有价值的结果， 这两个合作者在该领域和他们过去的记录， 出版物。 该研究计划包括生态和 社会对灵长类动物繁殖的影响， 在野生动物管理和人类 生殖行为

Description: This project supports Dr. Johnson for research work on rhesus monkeys, with an Indian scientist, Dr. (Mrs.) Iqbal Malik, Institute of Home Economics, University of Delhi, India. They plan to study the maternal investment behavior and seek to identify the ecological and social factors, producing variability in the length and frequency of the infants' nursing bouts. Special attention will be paid to two factors; maternal time budgets and the availability of solid foods accessible to young infants. The current prediction is that mothers who allow infants to nurse more often or longer bouts delay the reproduction cycle and thus permit these youngsters to grow relatively older by the time they are weened. This is based on the assumption, known for human mothers, that their is a strong correlation between frequent nursing bouts of short duration and a prolonged lactational infertility. The research will be carried over two birth seasons by observing the rhesus monkeys within a natural free-ranging population in India. Scope: The two scientists have collaborated in the past on research in this field. The proposed work is timely and is likely to produce valuable results given the experience of the two collaborators in the field and their past record of publications. The research plan includes ecological and social influences on reproduction of primates and has important applications in wildlife management and in human reproductive behavior.
