感觉驱动预测信号发生的条件对信号、感觉系统和行为有很大的影响。生态遗传学方法与感官驱动的结合取得了丰硕的成果。生态遗传学方法比较经历不同环境的种群，并询问种群差异是否具有适应性以及遗传和/或环境变异的结果。蓝鳍鳉鱼很好地体现了信号环境的多方面影响。在这个系统中，具有蓝色臀鳍的雄性在缺乏紫外线/蓝光的单宁染色沼泽中大量存在，但在紫外线/蓝光丰富的清澈泉水中则不存在。过去的研究表明，照明环境塑造了颜色模式、视觉系统和行为的遗传和环境变化。关于产生紫外线/蓝光与蓝色雄性丰度之间的跨群体相关性的选择性力量，人们知之甚少。在这里，我们提出了三个新实验，研究照明环境对雄性竞争、雌性择偶和捕食的作用。我们发现照明环境对雄性竞争有很大影响，蓝色雄性在茶渍水中比在清水中更有可能占据主导地位。我们对捕食的初步研究表明，与清水相比，蓝色雄性在茶渍水中可能更不容易受到捕食。然而，几乎没有证据表明女性偏爱蓝色男性。由此产生的模式是一种照明环境对遗传变异和表型可塑性的影响与选择方向相匹配的模式，并且有利于沼泽中蓝色雄性的表达。
Sensory drive predicts that the conditions under which signaling takes place have large effects on signals, sensory systems, and behavior. The coupling of an ecological genetics approach with sensory drive has been fruitful. An ecological genetics approach compares populations that experience different environments and asks whether population differences are adaptive and are the result of genetic and/or environmental variation. The multi-faceted effects of signaling environments are well-exemplified by the bluefin killifish. In this system, males with blue anal fins are abundant in tannin-stained swamps that lack UV/blue light but are absent in clear springs where UV/blue light is abundant. Past work indicates that lighting environments shape genetic and environmental variation in color patterns, visual systems, and behavior. Less is known about the selective forces creating the across population correlations between UV/blue light and the abundance of blue males. Here, we present three new experiments that investigate the roles of lighting environments on male competition, female mate choice, and predation. We found strong effects of lighting environments on male competition where blue males were more likely to emerge as dominant in tea-stained water than in clear water. Our preliminary study on predation indicated that blue males may be less susceptible to predation in tea-stained water than in clear water. However, there was little evidence for female preferences favoring blue males. The resulting pattern is one where the effects of lighting environments on genetic variation and phenotypic plasticity match the direction of selection and favor the expression of blue males in swamps.
