项目摘要
Biological communication in large animal groups is often accompanied by immense noise levels due to the presence of multiple signals and interference from the environment. One common way to deal with noise is to synchronize the signals, so that individuals signal in unison. Communication in well-studied synchronous animal groups across a broad range of organisms (frogs, fish, birds, and primates) is characterized by complex signals. In contrast, the PI will work with a tractable model system of firefly swarms where communication signals are visual, in the form of approximately digital light flashes, and visually traceable in three dimensions, even throughout large swarms of motile individuals. The PI will combine field and lab experiments with physical and information-theoretic theories for signal synchronization, using firefly swarms as a model system. This will enable fundamental advances in our understanding of communication strategies and enable the PI to integrate models and experiments across a wide range of length and time scales. The PI will focus on fundamental aspects of signal synchronization. The PI will use innovative field-recording technologies for fireflies and Virtual Reality (VR) systems to obtain quantitative spatiotemporal recordings of firefly flashes and test hypotheses about synchronous communication by exposing the fireflies to carefully designed visual stimulus. These information-rich datasets will facilitate the development and validation of agent-based models of possible underlying mechanisms. In turn, modeling can provide feedback on experiment design and serve as a tool to design VR stimuli whose responses will either validate or disprove a given hypothesis. This interwoven theory-experiment approach will allow an unprecedented level of model validation via simultaneous refinement of both models and experiments until the underlying principles are extracted and clarified. The same approach will directly inform the PI's educational goals as they develop a class that will engage students in concepts of animal communication via visualization of computational and experimental data. Therefore, this CAREER award will fundamentally advance the PI's long-term goals by providing insight into the principles that enable synchronization and incorporating the acquired firefly data in STEM education.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.
由于存在多种信号和来自环境的干扰,大型动物群体中的生物交流通常伴随着巨大的噪音水平。处理噪音的一种常见方法是同步信号,以便个体发出一致的信号。经过深入研究的多种生物(青蛙、鱼类、鸟类和灵长类动物)同步动物群体的交流具有复杂信号的特点。相比之下,PI将使用易于处理的萤火虫群模型系统,其中通信信号是视觉的,以近似数字闪光的形式,并且可以在三个维度上进行视觉追踪,甚至在大群活动个体中也是如此。 PI 将使用萤火虫群作为模型系统,将现场和实验室实验与信号同步的物理和信息论理论相结合。这将使我们对沟通策略的理解取得根本性进展,并使 PI 能够在广泛的长度和时间尺度上集成模型和实验。 PI 将重点关注信号同步的基本方面。 PI 将使用创新的萤火虫现场记录技术和虚拟现实 (VR) 系统来获取萤火虫闪光的定量时空记录,并通过将萤火虫暴露在精心设计的视觉刺激下来测试有关同步通信的假设。这些信息丰富的数据集将有助于开发和验证可能的底层机制的基于代理的模型。反过来,建模可以提供实验设计的反馈,并作为设计 VR 刺激的工具,其响应将验证或反驳给定的假设。这种交织的理论与实验方法将通过同时改进模型和实验,直到提取和澄清基本原理,从而实现前所未有的模型验证水平。同样的方法将直接告知 PI 的教育目标,因为他们开发了一门课程,通过计算和实验数据的可视化让学生了解动物交流的概念。因此,该职业奖将从根本上推进 PI 的长期目标,通过提供对实现同步的原则的见解并将获得的萤火虫数据纳入 STEM 教育。该奖项反映了 NSF 的法定使命,并通过使用基金会的智力价值和更广泛的影响审查标准。
