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.

摘要 Adkins-Regan 9514088 拟议研究的目标是分析导致成年配偶选择和择偶偏好的发育过程，特别是性别二态性（男性和女性不同）的偏好。 该项目将重点关注配偶选择、对异性伴侣的偏好（性伴侣偏好）以及非常适合该目标的物种，斑胸草雀在孵化后的前两周接受雌激素处理，并圈养在全雌性斑胸草雀中，在孵化后的前两周接受雌激素治疗，并从 40 天开始饲养在全雌性环境中（独立于雌性斑马雀）。 父母）到100天（青年期）然后更喜欢与其他雌性配对。 为了解决这一发现提出的重要问题，我们将进行一系列的实验，在这些实验中，动物在发育过程中暴露于不同的激素或社会环境操纵下，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），并将阐明激素和经验影响在发育过程中相互作用的方式。 这项工作将增进我们对配偶选择和生殖行为发展的理解。
