Abstract IOS 1311393 DISSERTATION RESEARCH: Assessment of Signals in Communication NetworksCommunication is a cornerstone of animal behavior, mediating disparate interactions such as among predators and prey, parents and offspring, siblings, social groups, and prospective mates, to name a few. Sometimes multiple receivers are able to detect the same set of communication signals, and in these cases communication can be described as occurring within "networks." A major open question in animal behavior is whether signals used in communication networks are interpreted or assessed any differently than in single sender/ single receiver interactions. To address this question, the research team will investigate how signal receivers make direct comparisons among multiple signals. Research will be conducted on a songbird species, the Chipping Sparrow (Spizella passerina), and will aim to answer two questions; (i) how do females assess prospective mates when sampling multiple males that vary in preferred signal properties? and (ii) how do networks of males respond to territorial intrusions when threat levels as signalled in song varies? This project encompasses both lab and field components, by testing female preferences in an operant paradigm in the lab, and by using playback and a microphone array to test a network response to territorial intrusion in the field. Results from this project will address the hypothesis that relative signal strength can influence both mating decisions and territorial interactions, and could therefore ultimately affect the strength and/or direction of sexual selection. This project presents opportunities to train undergraduate researchers and also generate data suitable for senior theses. Furthermore, the Co-PI organizes a science outreach activity, the "Science Café," (www.oebsciencecafe.org) and findings will be presented by the co-PI to the community at a Café event in 2014. All data created as a result of this project will be stored in replicate on hard drives subject to regular back-ups, and will be accessible to other researchers via request.

摘要IOS 1311393论文研究：通信网络中的信号评估通信是动物行为的基石，介导不同的相互作用，如捕食者和猎物，父母和后代，兄弟姐妹，社会群体和未来的配偶，仅举几例。 有时，多个接收器能够检测到同一组通信信号，在这些情况下，通信可以被描述为发生在“网络”内。“动物行为中的一个主要开放问题是，通信网络中使用的信号是否与单个发送者/单个接收者交互中的信号有任何不同的解释或评估。 为了解决这个问题，研究小组将研究信号接收器如何在多个信号之间进行直接比较。 研究将进行的鸣禽物种，芯片麻雀（Spizella passerina），并将旨在回答两个问题;（一）女性如何评估未来的伴侣时，抽样多个男性不同的首选信号属性？以及（ii）当威胁程度在歌曲中有所不同时，雄性网络如何应对领土入侵？ 该项目包括实验室和现场的组成部分，通过测试女性的喜好在实验室中的操作范式，并通过使用回放和麦克风阵列来测试网络响应领域的领土入侵。 从这个项目的结果将解决的假设，相对信号强度可以影响交配决策和领土的相互作用，因此可能最终影响的强度和/或方向的性选择。 该项目提供了培训本科生研究人员的机会，并生成适合高级论文的数据。 此外，共同主要研究者组织了一项科学外联活动，即“科学咖啡馆”（www.oebsciencecafe.org），共同主要研究者将在2014年的咖啡馆活动中向社区介绍研究结果。 作为该项目的结果创建的所有数据将被存储在定期备份的硬盘驱动器上的副本，并将通过请求访问其他研究人员。
