孔雀鱼（Poecilia reticulata）自然种群的颜色模式是性选择和捕食回避之间的妥协。 现场数据的环境光光谱，水的传输光谱，求偶和攻击距离，和锥色素的孔雀鱼和它们的捕食者被用来计算的显着性的孔雀鱼的视觉条件和视觉的各种组合下的措施。 结果表明，颜色模式是相对更明显的孔雀鱼在求爱的时间和地点，相对不太明显的时间和地点的最大捕食风险。 讨论了视觉进化、视觉传达和行为的一些含义。
Color patterns of natural populations of guppies (Poecilia reticulata) are a compromise between sexual selection and predation avoidance. Field data on ambient light spectra, water transmission spectra, courtship and attack distances, and cone pigments of guppies and their predators were used to calculate measures of conspicuousness of guppies under various combinations of visual conditions and vision. The results suggest that color patterns are relatively more conspicuous to guppies at the times and places of courtship and relatively less conspicuous at the times and places of maximum predator risk. Some implications to the evolution of vision, visual communication and behavior are discussed.
