Evolution of sensory integration in jumping spiders

描述（由申请人提供）：我建议评估跨跳蛛属的多模态信号的功能和演变。我的研究将发展我们对感觉整合和多模式沟通的理解，在多个层次的分析。(1)通过评估雄性多模态显示和基于这些特征的雌性选择，我将记录不同种类的蜘蛛在不同程度上使用多模态信号的多模态信号的功能：（2）我将评估和测量视觉装饰，动态运动显示和地震信号的复杂性，并使用系统发育技术实证检验关于特征进化和显示复杂性的假设;（3）我将构建一个计算模型的复杂字符的进化和测试假设增加的感觉整合和物种多样化的进化;（4）我将检查的假设约束信号。使用测量的复杂性，我将使用信息理论来估计显示器上的信息内容的约束，然后使用系统发育分析来测试约束是否驱动多模态信号的演变。这个拟议的项目将提供重要的关键组成部分，以了解动物的感觉整合。

DESCRIPTION (provided by applicant): I propose to evaluate the function and evolution of multimodal signals across a jumping spider genus. My studies will develop our understanding of sensory integration and multimodal communication at multiple levels of analysis. (1) I propose to document the function of multimodal signaling in different species of spiders that use multimodal signaling to varying degrees by evaluating male multimodal displays and female choice based on these traits; (2) I will evaluate and measure the complexity of visual ornaments, dynamic movement displays, and seismic signals and using phylogenetic techniques empirically test hypotheses on the evolution of traits and complexity in displays; (3) I will construct a computational model for the evolution of complex character evolution and test hypothesis on increased sensory integration and species diversification; (4) I will examine hypotheses on constraints in signals. Using measurements of complexity I will use information theory to estimate constraints on the information content of displays and then use phylogenetic analyses to test whether constraints drive the evolution of multimodal signals. This proposed project will provide important key components to understanding sensory integration in animals.
