本研究预测目标检测性能在特定物种的栖息地为6冲浪（Embiototoporiae）生活在光学可变的加州海带森林。使用物种特异性测量栖息地的辐照度和光感受器吸光度在一个简单的二色模型的亮度和色度检测，物种的测量crossigments的估计性能进行了比较，为每个栖息地的理论最大值。模拟结果表明，光感受器的峰值吸光度（λ（最大）），光感受器的光密度和光环境的变化可能会影响检测性能。亮度检测的估计性能一直很高，而彩色检测因栖息地而异，并表现出显着的改善，增加锥类之间的光密度差异。(C)2004爱思唯尔有限公司保留所有权利。
This study predicts target detection performance in species-specific habitats for six surfperch (Embiotocidae) living in optically variable California kelp forests. Using species-specific measurements of habitat irradiance and photoreceptor absorbance in a simple dichromatic model for luminance and chromatic detection, the estimated performance of species' measured photopigments was compared to the theoretical maximum for each habitat. Modelling results suggest that changes in peak photoreceptor absorbance (lambda(max)), photoreceptor optical density, and photic environment may affect detection performance. Estimated performances for luminance detection were consistently high, while chromatic detection varied by habitat and demonstrated substantial improvements with increasing optical density differences between cone classes.
