项目摘要

The role of sexual selection in the process of speciation has been long debated, in part due to a lack of observations in nature for the mechanisms that have been proposed in theoretical models. This project will fill gaps in our understanding of speciation by identifying the conditions under which learning, a process common to the development of reproductive behaviors in many animal taxa, may facilitate speciation. The research in this project links experiments to understand how mating behaviors are formed with models that build on those findings to make predictions at the level of populations and diverging lineages. The subject of the behavioral experiments is the strawberry poison frog, a species that shows striking diversity in coloration and for which color-assortative behaviors are known to be shaped by learning. The theoretical models developed in each objective will broaden the project’s findings by asking how different types of mating traits and learning that are found in other animals affect the likelihood of speciation. The project’s objectives in education and outreach include training a diverse group of students, continuing involvement with citizen science programs and development of K-12 curricula aimed at teaching concepts in biology related to the research, including evolution, animal behavior, and the factors that impact biodiversity.The project’s first objective will integrate a rearing experiment and behavioral assays with population-genetic modeling to ask how learning from different tutors (and at different stages in development) affects the likelihood of behavioral reproductive isolation. The second objective will use a behavioral assay, coupled with theoretical modeling, to ask how variation in an animal’s perception of mating traits, and the genetic architecture that underlies those mating traits, interact to affect the likelihood of speciation. The project’s final objective will use a field study, coupled with a third theoretical model, to investigate how evolution of the strength of learned behavioral biases impacts the likelihood of speciation.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

性选择在规范过程中的作用长期以来一直在争论，部分原因是自然界缺乏对理论模型中提出的机制的观察。该项目将通过确定学习条件（在许多动物分类单元中生殖行为发展的过程）中的条件来填补我们对规范的理解空白，这可能有助于规格。该项目中的研究链接了实验，以了解如何形成交配行为的模型，这些模型基于这些发现，以在人群水平和分歧的谱系水平上进行预测。行为实验的主题是草莓毒青蛙，该物种表现出颜色惊人的多样性，并且已知通过学习塑造了颜色形成的行为。 The theoretical models developed in each objective will broaden the project’s findings by asking how different types of mating traits and learning that are found in other animals The project’s objectives in education and outreach include training a divers group of students, continuing involvement with citizen science programs and development of K-12 curricula aimed at teaching concepts in biology related to the research, including evolution, animal behavior, and the factors that impact biodiversity.The project’s first objective will integrate a rearing experiment and采用种群基因建模的行为分析，以询问从不同的导师那里学习（在发展中的不同阶段）如何影响行为生殖隔离的可能性。第二个目标将使用行为评估，再加上理论建模，询问动物对交配特征的看法的变化以及构成这些交配特征的基础的遗传结构，以影响规格的可能性。该项目的最终目标将使用现场研究，再加上第三个理论模型，以研究学习行为偏见的强度的演变如何影响规范的可能性。该奖项反映了NSF的法定任务，并被认为是通过使用基金会的知识分子和更广泛影响的审查审查标准来通过评估来通过评估来获得支持的。
