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.

本研究的目的是分析导致成年配偶选择和配偶偏好的发育过程，特别是性别二态（雄性和雌性不同）的偏好。该项目将重点关注配偶选择的一个特别强大和广泛的方面，对异性伴侣的偏好（性伴侣偏好），以及一个非常适合这一目标的物种。斑胸草雀在产后两周内接受雌激素治疗，在产后两周内接受雌激素治疗的斑胸草雀在产后40天（脱离父母）至100天（成年期）的全雌性环境中饲养，然后倾向于与其他雌性交配。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，在发育过程中，将编年史暴露在不同的激素或社会环境中，然后测试性伴侣偏好——发育早期激素产生的组织效应，以及性印记——并阐明激素和经验影响在发育过程中相互作用的方式。这项工作将促进我们对配偶选择和生殖行为发展的理解。
