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是行为生物学的核心问题。 是什么防止弱，低质量的人通过信号表明自己坚强而“作弊”？ 一般的答案是，质量信号是昂贵的，并且与高质量的个体相比，高质量的高质量信号相对昂贵。该项目将通过测试两个众所周知的成本之间的相互作用：积极的社会成本和生理成本，对保持信号诚实的因素有了新的看法。信号不准确的短期和长期后果将通过行为观察和对polistes polistes dominulus Paper Wasps中的内分泌滴度的测量进行测试。 知识分子的优点：尽管在理解动物交流系统的诚实方面取得了很多进展，但许多知名的饰物缺乏明显的成本。 此外，与理解积极的社会成本如何保持进化时间的信号诚实有关，存在理论和经验挑战。 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，它将解决与了解社会成本相关的许多挑战，并扩大该假设对不同系统的适用性。总体而言，了解生理学和社会成本之间的动态反馈应增加对动物交流系统可靠性的理解。更广泛的影响：对本科生的培训将是该项目的主要组成部分，因为这项研究有效地吸引了学生的兴趣，并且有抱负的研究人员可以使用这些技术。其他教育活动将包括参加公共科学教育计划和对当地学校的访问。
