项目摘要

A central goal of evolutionary biology is to understand both how new species form and the processes that maintain boundaries between species. This study will investigate the evolutionary genetic patterns of the early versus final stages of reproductive isolation in the fly Drosophila subquinaria. Some females of this species display increased behavioral discrimination both against males of a closely related species as well as against certain males of their own species. This research will test whether the ecological processes and genetic mechanisms that reinforce boundaries between different species can result in behavioral isolation among different populations of the same species. The methods will integrate field studies, genetic mapping, and evolutionary genomic approaches.This funding will integrate research with teaching and learning to provide research opportunities and to develop educational materials that advance the understanding of evolutionary processes at the broader level. Educational activities will translate the focal ideas of the research into inquiry-based classroom exercises that will help students understand why evolution is important in their daily lives through learning about how it operates and the consequences of evolution in action. Graduate students, undergraduates, and high school teachers will be involved in all aspects of the scientific research, curriculum development, and public outreach.

进化生物学的一个核心目标是了解新物种形成和维持物种之间边界的过程如何。这项研究将研究果蝇果蝇亚果中生殖隔离的早期和最终阶段的进化遗传模式。该物种的某些女性表现出对紧密相关物种的男性以及对自己的某些雄性物种的男性的行为歧视的增加。这项研究将测试加强不同物种之间边界的生态过程和遗传机制是否会导致同一物种不同种群之间的行为隔离。这些方法将整合现场研究，遗传图和进化基因组方法。这项资金将与教学和学习相结合，以提供研究机会并开发教育材料，以提高对更广泛层面的进化过程的理解。教育活动将将研究的重点转化为基于询问的课堂练习，这将通过了解其运作方式以及行动中进化的后果来帮助学生了解为什么进化在日常生活中很重要。研究生，本科生和高中教师将参与科学研究，课程发展和公共宣传的各个方面。
