项目摘要

Males often use conspicuous signals to attract females but, in doing so, they may also attract the unwanted attention of parasites. How does one species come to have the ability to eavesdrop on the signals of other species? This project will address this question integrating multiple levels of analysis (behavioral, acoustical, biomechanical, and physiological) in laboratory and field experiments to comprehensively investigate eavesdropping behavior in of midges that home-in on the calls of singing frogs. This investigation will characterize the midge's ear and relate the midge's hearing ability to its evolutionary origins. This project will ultimately determine the sensory and behavioral adaptations driven the ecology and evolution of eavesdropping in frog-biting midges.Intellectual Merit: The project will address a long-standing biological mystery by exploring the origins of eavesdropping of between animal species. By examining an evolutionary innovations in insect hearing, this study will have implications for microphone design, bioacoustics and the co-evolution of sexual and exploitive communication. In addition, the midge-frog system has parallels to the mosquito-human relationship, which enlarges the evolutionary scope of the questions addressed here. Overall, understanding the mechanisms underlying the evolution and sensory ecology of eavesdropping will increase our understanding of exploitation in animal communication systems.Broader Impacts: Training of undergraduate and graduate students in cutting edge techniques in animal communication and neuroethology will be an important component of this project. Additional educational activities will include workshops at elementary schools about frog calling behavior and eavesdroppers to generate interest and enthusiasm about animal behavior and science in general.

雄性经常使用明显的信号来吸引雌性，但这样做也可能引起寄生虫的不必要的注意。一个物种是如何拥有窃听其他物种信号的能力的？本项目将在实验室和现场实验中整合多个层面的分析（行为学、声学、生物力学和生理学）来解决这个问题，全面研究蠓在鸣叫青蛙的叫声中栖息的窃听行为。这项研究将描述蠓的耳朵特征，并将蠓的听力能力与其进化起源联系起来。该项目将最终确定叮咬青蛙的蠓对窃听的生态学和进化的感官和行为适应。智力价值：该项目将通过探索动物物种之间窃听的起源来解决一个长期存在的生物学之谜。通过研究昆虫听觉的进化创新，本研究将对麦克风设计、生物声学以及性和剥削交流的共同进化产生影响。此外，蠓蛙系统与蚊子与人的关系有相似之处，这扩大了本文讨论的问题的进化范围。总的来说，了解窃听的进化和感觉生态机制将增加我们对动物通信系统利用的理解。更广泛的影响：培养本科生和研究生在动物交流和神经行为学方面的前沿技术将是这个项目的重要组成部分。其他教育活动还包括在小学举办关于青蛙叫声行为和窃听者的讲习班，以激发人们对动物行为和科学的兴趣和热情。
