Developmental Mechanisms of Reproductive Choice

摘要 阿德金斯-里根9514088 拟议研究的目标是分析导致成年人择偶和择偶偏好的发展过程，特别是性别二态性（男性和女性不同）的偏好。 该项目将重点关注择偶中一个特别强大和广泛的方面，即对异性伴侣的偏好（性伴侣偏好），以及一个非常适合这个目标的物种，在孵化后的前两周用雌激素处理的斑胸草雀，并圈养在全雌性斑胸草雀中，在孵化后的前两周用雌激素处理的斑胸草雀，并圈养在全雌性斑胸草雀中，从40天（独立于父母）到100天（成年初期）的雌性环境，然后喜欢与其他雌性配对。 为了解决这一发现提出的重要问题，将进行一系列实验，在这些实验中，annals在发育过程中暴露于不同的激素或社会环境操纵，然后测试性伴侣偏好-激素在发育早期产生的组织效应，和性印记-并将阐明在发展过程中激素和经验的影响相互作用的方式。 这项工作将促进我们对配偶选择和生殖行为发展的理解。

Abstract Adkins-Regan 9514088 The goal of the proposed research is to analyze developmental processes leading to adult mate choice and mate preferences, especially preferences that are sexually dimorphic (different in males and females). The project will focus on a particularly robust and widespread aspect of mate choice, preference for opposite-sex partners (sexual partner preference), and a species well-suited to the goal, the zebra finches treated with estrogen during the first two weeks posthatch and housed in an all-female zebra finches treated with estrogen during the first two weeks posthatch and housed in an all-female environment from 40 days (independence from the parents)to 100 days (young adulthood) then prefer to pair with other females. In order to address important questions raised by this discovery, a series of experiments will be conducted in which annals are exposed to different hormonal or social environment manipulations during development and then tested for sexual partner preference--organizational effects of hormones produce early in development, and sexual imprinting--and will elucidate the manner in which hormonal and experiential influences interact during development. This work will advance our understanding of mate choice and of reproductive behavior development.
