DISSERTATION RESEARCH: Adaptive Functions of California Towhee (Pipilo crissalis) Duet Song

论文研究：适应功能的加州Towhee（Pipilo salis）二重唱歌曲PI：沃尔特·凯尼格和Lauryn BenedictThe拟议的研究将探讨加州Towhee（Pipilo salis）二重唱歌曲作为一种工具，用于解决对社会一夫一妻制的鸟类之间的声乐交流的演变。以前的研究duetting一直很少，特别是在温带物种，并没有达成共识，就这个复杂的特征的功能意义。二重唱的离散生殖成本和效益将被指定为允许的预测和相关假设的实验测试。先前的研究表明，在加州Towhees二重唱发生在各种情况下，如领土防御，配偶守卫，确保合作伙伴的承诺，和个人的认可。这项研究将提供一个综合的，完整的分析声乐二重奏功能，考虑到多个潜在的好处，个人对二重奏，并将是第一个研究，实验测试多种适应性假设的功能，二重奏歌曲在鸟类。

Dissertation Research: Adaptive functions of California Towhee (Pipilo crissalis) duet songPI: Walter Koenig and Lauryn BenedictThe proposed research will examine California Towhee (Pipilo crissalis) duet song as a tool for addressing the evolution of vocal communication between pairs of socially monogamous birds. Previous studies of duetting have been few, especially among temperate species, and have failed to arrive at a general consensus regarding the functional significance of this complex trait. Discrete reproductive costs and benefits of duet song will be specified to allow for experimental tests of predictions and relevant hypotheses. Previous research suggests that duetting in California Towhees occurs in a variety of contexts such as territory defense, mate guarding, ensuring partner commitment, and individual recognition. This study will provide an integrated, complete analysis of vocal duet function by considering multiple potential benefits accrued to individuals in pairs that duet and will be one of the first studies to experimentally test multiple adaptive hypotheses for the function of duet song in birds.
