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.

许多生物使用声音，气味，颜色或行为相互交流。繁殖通常需要男性和女性之间的交流，而交配的交流在物种之间有所不同，从而阻止了不同物种之间的交配。当男性交配特征发生巨大变化时，有和没有新信号的类型可能会被生殖隔离，尤其是当信号接收器（通常是女性）随着男性信号而变化时。研究人员发现了一种新颖的歌曲类型“ Purring”，在Teleogryllus Oceanicus长期研究的太平洋野外人群中。雄性板球使用专门的机翼结构制作歌曲，以吸引女性并敦促她们交配。研究人员利用了这一机会，通过测量和跟踪新的Purring歌曲的组成部分来了解交配信号演变的最早阶段。这首新歌可检测到同一物种的女板球和寄生虫苍蝇。雌性寄生虫蝇使用歌曲来定位主人板球，然后将幼虫放在它们上，然后将幼虫钻入板球，然后将其吞噬板球的身体。因此，研究人员还将测量女性板球和苍蝇的偏好，并研究新歌的进化史和基因组基础。研究人员将动物交流的当代发展与科学传播联系起来，该计划（Stemcomm）建立在扩大科学中的多样性和包容性以及提高参与者的跨文化素养方面。 STEMCOMM将改善本科和研究生在科学沟通方面的培训，同时让服务不足的城市和夏威夷本地学生进行领先的研究。进化新颖性的起源仍然难以捉摸，因为在作用中捕捉新型特质进化的固有困难。研究人员在太平洋田野板球teleogryllus Oceanicus的夏威夷人群中发现了一首新歌（“ purring”），在多个人群中的频率正在增加。这首小说的歌曲与用于识别同种和首选伴侣的特征的典型歌曲有所不同，并且是女性和窃听自然敌人的可检测到的。这一发现提供了一个记录新型男性特征的起源及其对信号偏爱关系和实时隔离的后果的机会。祖传信号和偏好是良好的特征，并且该系统以快速的通信发展而闻名，尤其是在响应于声学方向的寄生虫苍蝇时。研究人员将跟踪包含20代男性的重复人群，揭示新的特征如何与预期和意外接收者的偏好和感知能力相同（或不），并将探讨纯板球的进化历史和基因组建筑。将现场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。该项目通过以K-12教育中的研究生干研究员为模型的新科学传播计划无缝整合研究和教育，将研究适应非专业观众，并增强了科学的多样性和包容性。参与者将与K-12老师合作，在课堂上共同开发可发布的课程和试点活动，少数少女夏令营以及夏威夷的社区外展计划。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子和广泛影响的评估来通过评估来支持的，这是值得的。
