项目摘要

Many organisms communicate with one another using sounds, smells, colors, or behaviors. Communication between males and females is often required for reproduction, and mating communication differs between species, preventing mating between different species. When male mating characteristics change dramatically, types with and without a new signal can become reproductively isolated, particularly when the preferences of signal receivers (often females) change in step with the male signals. The researcher discovered a novel song type, 'purring', in long-studied populations of Pacific field crickets, Teleogryllus oceanicus. Male crickets produce songs using specialized wing structures to attract females and urge them to mate. The researcher capitalizes on this opportunity to understand the earliest stages of mating signal evolution by measuring and tracking the components of the new purring song. The new song is detectable to female crickets of the same species and to a parasitoid fly. Female parasitoid flies use song to locate host crickets and then deposit larvae on them that will burrow into and later eat their way out of the crickets' body. The researcher will thus also measure preferences of female crickets and flies and investigate both the evolutionary history and genomic basis of the new song. The researcher links the contemporary evolution of animal communication with science communication through a program (STEMComm) founded on increasing diversity and inclusion in science and on increasing the cross-cultural literacy of participants. STEMComm will improve undergraduate and graduate students' training in science communication while engaging underserved urban and native Hawaiian students with leading-edge research. The origins of evolutionary novelty remain elusive because of the inherent difficulty of catching novel trait evolution in action. The researcher discovered a new song ('purring') in Hawaiian populations of the Pacific field cricket, Teleogryllus oceanicus, that is increasing in frequency in multiple populations. The novel song differs from the typical one in characteristics used to identify conspecifics and preferred mates, and is detectable to females and an eavesdropping natural enemy. This discovery affords an opportunity to document the origin of a novel male trait and its consequences for signal-preference relationships and sexual isolation in real time. Ancestral signals and preferences are well-characterized, and the system is known for rapid evolution of communication, particularly in response to an acoustically orienting parasitoid fly. The researcher will track replicate populations that contain purring males for 20 generations, revealing how novel traits come to coevolve (or not) with the preferences and perceptual capabilities of intended and unintended receivers, and will probe the evolutionary history and genomic architecture of purring crickets. Combining field studies with modern genomic techniques will provide an integrative understanding of the why and how of evolutionary novelty. The project seamlessly integrates research and education through a new science communication program modeled after Graduate STEM Fellows in K-12 Education, adapting the research for a non-specialist audience and enhancing diversity and inclusion in science. Participants will partner with K-12 teachers to co-develop publishable curricula and pilot activities in classrooms, a summer camp for minoritized girls, and a community outreach program in Hawaii.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.

许多生物体通过声音、气味、颜色或行为相互交流。雄性和雌性之间的交流通常是繁殖所必需的，而物种之间的交配交流存在差异，从而阻止了不同物种之间的交配。当雄性交配特征发生巨大变化时，有或没有新信号的类型可能会变得生殖隔离，特别是当信号接收者（通常是雌性）的偏好随着雄性信号而变化时。研究人员在长期研究的太平洋田蟋蟀（Teleogryllus oceanicus）种群中发现了一种新颖的歌曲类型，即“咕噜声”。雄性蟋蟀利用特殊的翅膀结构发出歌曲来吸引雌性并促使它们交配。研究人员利用这个机会通过测量和跟踪新的咕噜声的组成部分来了解交配信号进化的最早阶段。同一物种的雌性蟋蟀和寄生蝇可以检测到这首新歌。雌性寄生蝇利用鸣声来定位寄主蟋蟀，然后将幼虫沉积在它们身上，幼虫会钻入蟋蟀体内，然后吃掉蟋蟀的身体。因此，研究人员还将测量雌性蟋蟀和苍蝇的偏好，并研究新歌曲的进化历史和基因组基础。研究人员通过一个项目（STEMComm）将动物交流的当代演变与科学交流联系起来，该项目的基础是增加科学的多样性和包容性以及提高参与者的跨文化素养。 STEMComm 将改善本科生和研究生的科学传播培训，同时让服务不足的城市和夏威夷本土学生参与前沿研究。进化新颖性的起源仍然难以捉摸，因为捕捉新特征进化的实际情况存在固有的困难。研究人员在太平洋田蟋蟀夏威夷种群中发现了一种新的歌曲（“咕噜声”），这种歌曲在多个种群中的频率正在增加。这首新颖的歌曲与典型歌曲的不同之处在于用于识别同种动物和首选配偶的特征，并且可以被雌性和窃听的天敌察觉。这一发现提供了一个机会来实时记录一种新的男性特征的起源及其对信号偏好关系和性隔离的影响。祖先的信号和偏好具有明确的特征，并且该系统以通信的快速进化而闻名，特别是对声学定向寄生蝇的响应。研究人员将跟踪包含咕噜雄性蟋蟀的复制种群20代，揭示新特征如何与有意和无意的接收者的偏好和感知能力共同进化（或不共同进化），并将探索咕噜蟋蟀的进化历史和基因组结构。将实地研究与现代基因组技术相结合将提供对进化新颖性的原因和方式的综合理解。该项目通过模仿 K-12 教育研究生 STEM 研究员的新科学传播计划，将研究和教育无缝结合起来，使研究适合非专业受众，并增强科学的多样性和包容性。参与者将与 K-12 教师合作，共同开发可发布的课程和课堂试点活动、少数民族女孩夏令营以及夏威夷的社区外展计划。该奖项反映了 NSF 的法定使命，并通过评估被认为值得支持利用基金会的智力优势和更广泛的影响审查标准。
