The honesty of animal communication systems is a central issue in behavioral biology. What prevents weak, low quality individuals from "cheating" by signaling that they are strong? The general answer is that quality signals are costly and signaling a high level of quality is relatively more costly for low quality than high quality individuals. This project will take a new perspective on the factors that maintain signal honesty by testing the interplay between two well-known costs: aggressive social costs and physiological costs. The short and long term consequences of signal inaccuracy will be tested via behavioral observation and measurement of endocrine titers in Polistes dominulus paper wasps. Intellectual merit: Although much progress has been made toward understanding the honesty of animal communication systems, many well-known ornaments lack clear costs. Further, there are theoretical and empirical challenges associated with understanding how aggressive social costs maintain signal honesty over evolutionary time. Our proposal will extend and re-define current hypotheses by testing the physiological consequences of social punishment. As such, it will address many of the challenges associated with understanding social costs and broaden the applicability of this hypothesis to diverse systems. Overall, understanding the dynamic feedbacks between physiology and social costs should increase understanding of the reliability of animal communication systems. Broader impacts: Training of undergraduate students will be a major component of the project, as this research is effective at capturing student interest and the techniques are accessible to aspiring researchers. Additional educational activities will include participation in public science education programs and visits to local schools.

动物交流系统的诚实性是行为生物学的一个中心问题。 是什么阻止软弱、低素质的个体通过发出他们强壮的信号来“作弊”？ 一般的答案是，质量信号是昂贵的，而对于低质量的人来说，发出高质量的信号比发出高质量的信号相对更昂贵。该项目将通过测试两个众所周知的成本之间的相互作用，对保持信号诚实的因素采取新的视角：积极的社会成本和生理成本。信号不准确的短期和长期后果将通过行为观察和内分泌滴度的测量进行测试。 智力优点：尽管在理解动物交流系统的诚实性方面已经取得了很大进展，但许多著名的装饰品缺乏明确的成本。 此外，还有理论和经验的挑战与理解如何积极的社会成本保持信号的诚实在进化的时间。 我们的建议将通过测试社会惩罚的生理后果来扩展和重新定义当前的假设。 因此，它将解决与理解社会成本相关的许多挑战，并将这一假设的适用性扩大到不同的系统。总的来说，了解生理学和社会成本之间的动态反馈应该增加对动物通信系统可靠性的理解。更广泛的影响：本科生的培训将是该项目的一个主要组成部分，因为这项研究是有效地捕捉学生的兴趣和技术是有抱负的研究人员访问。其他教育活动将包括参加公共科学教育项目和访问当地学校。
