Sexual selection can drive the evolution of dramatic morphological and behavioral signals. This selection acts on both specific components of signals and overall signals that combine multiple sources of information. By studying the structure and variability of signals and their components we can improve our understanding of how sexual selection operates. Signal integration can be understood through the lens of classical signaling hypotheses or more recently defined systems approaches. Using crickets (Acheta domesticus), we evaluated competing hypotheses about signal integration and how observed patterns of signal integration fit into both systems approaches and classic signaling hypotheses. We measured three call types of 127 male crickets multiple times for a total of 930 observations. We found evidence for an underlying integrated signaling syndrome from which both intra- and intersexual signals stemmed. This syndrome was also affected by mass, suggesting honest signaling in the species. The presence of an integrated syndrome demonstrates that intra- and intersexual signals are incorporated in a redundant signal strategy in Acheta domesticus. This support for honest and redundant signaling is also consistent with a systems framework description of signals as degenerate and functionally modular--demonstrating one way in which classic hypotheses can be integrated with modern systems approaches.

性别内和性间选择信号的整合

性选择可以驱动剧烈的形态和行为信号的演变。该选择作用于信号的特定分量以及组合了多种信息源的整体信号。通过研究信号及其成分的结构和变异性，我们可以增进对性选择如何运作的理解。可以通过经典的信号假设或最近定义的系统方法来理解信号集成。我们使用（Acheta domesticus）评估了关于信号整合的竞争假设，以及观察到的信号整合模式如何适用于系统方法和经典信号假设。我们多次测量了127种male的三种呼出类型，共进行了930次观察。我们发现了潜在的综合性信号综合症的证据，该综合性综合症源于内部和男性之间的信号。该综合征还受到质量的影响，表明该物种中存在诚实的信号。综合症候群的存在表明，在Acheta domesticus中，冗余信号策略中包含了内部和男性之间的信号。对诚实和冗余信令的这种支持也与对系统的退化和功能模块化的信号的系统框架描述相一致-展示了经典假设可以与现代系统方法集成的一种方式。综合症候群的存在表明，在Acheta domesticus中，冗余信号策略中包含了内部和男性之间的信号。这种对诚实和冗余信令的支持也与系统框架将信号描述为退化和功能模块化的方法相一致-展示了经典假设可以与现代系统方法集成的一种方式。综合症候群的存在表明，在Acheta domesticus中，冗余信号策略中包含了内部和男性之间的信号。这种对诚实和冗余信令的支持也与系统框架将信号描述为退化和功能模块化的方法相一致-展示了经典假设可以与现代系统方法集成的一种方式。
