Non-Technical Abstract Sensory Drive in a Variable Signaling Environment: An Investigation of Surfperch (Embiotocidae) Visual Communication Animals living in optically variable habitats encounter unique visual challenges when using color to communicate. Color patterns can change in appearance as the ambient light varies in its spectral distribution. The Californian coastal marine environment exhibits a wide range of spectral conditions depending on depth, water column productivity, and kelp canopy cover. Surfperch are a family of fish that live along optically variable Californian coast and have evolved diverse color patterns and distinct visual courtship signals. The specific goals of this research are to determine whethersurfperch species selectively court under specific spectral conditions, and whether female preference for males is affected by changes in spectral conditions. To investigate the first question, measurements of the visual pigments of the different fish species, the color patterns of the fish, and the ambient light conditions during various fish activities are collected with emphasis on comparing light conditions between courtship verses non-courtship activities. The second question will be address with a tank experiment that manipulates the light environment and observes female response to male courtship under different optical conditions. The primary significance of this project is in gaining a greater understanding of the evolution of signal diversity across the animal kingdom. However, the significance of this study reaches beyond evolutionary biology and into the fields of optical oceanography and visual science as it is the first study to examine the spectral variation in the shallow near-shore environment, and will provide a better understanding of the selective forces on the visual system by studying a visual properties of animals with particular environmental constraints.

非技术摘要 可变信号环境中的感官驱动：对 Surfperch（Embiotocidae）视觉交流的调查 生活在光学可变栖息地的动物在使用颜色进行交流时遇到独特的视觉挑战。 随着环境光光谱分布的变化，颜色图案的外观也会发生变化。 加利福尼亚沿海海洋环境呈现出广泛的光谱条件，具体取决于深度、水柱生产力和海带冠层覆盖。 冲浪鲈鱼是生活在光学可变的加利福尼亚海岸的鱼类家族，并进化出多种颜色图案和独特的视觉求偶信号。 这项研究的具体目标是确定冲浪鲈鱼物种是否会在特定的光谱条件下选择性地求爱，以及雌性对雄性的偏好是否会受到光谱条件变化的影响。 为了研究第一个问题，收集了不同鱼类的视觉色素、鱼的颜色图案以及各种鱼类活动期间的环境光条件的测量结果，重点是比较求偶活动与非求偶活动之间的光条件。 第二个问题将通过一个坦克实验来解决，该实验操纵光环境并观察不同光学条件下雌性对雄性求爱的反应。 该项目的主要意义在于更好地了解整个动物界信号多样性的演变。 然而，这项研究的意义超越了进化生物学，进入了光学海洋学和视觉科学领域，因为它是第一项研究浅近岸环境中光谱变化的研究，并将通过研究具有特定环境限制的动物的视觉特性，更好地理解视觉系统的选择力。
