自从在鱼类中发现红色荧光以来,人们投入了大量的精力来阐明其潜在的功能,其中之一就是信号。这意味着红色荧光和反射的结合应该在背景上产生可见的对比。在这里,我们展示了在5米和20米深度的自然光条件下雷公藤区的虹膜亮度测量。我们还测量了在这些深度的阴影和暴露的觅食地点的基底辐射。为了评估红色虹膜对这些基底的视觉对比度,我们使用受体噪声模型进行彩色对比度和迈克尔逊对比度进行消色差计算。在水深20 m处,T。Delaisiiris辐射产生强烈的消色差对比底物辐射,不管曝光,尽管底物荧光。考虑到600纳米以上的下行光在这个深度可以忽略不计,我们可以将这种效应归因于虹膜荧光。5 m时对比较弱。然而,在遮荫条件下,所有底物的红色反射和荧光所产生的总辐射仍然超过底物的辐射,而在暴露条件下,除了紫花苜蓿和紫花苜蓿外,其他底物都超过了底物的辐射。由于麻醉对虹膜荧光的负面影响,这些估计是保守的。我们得出的结论是,在自然环境ofT的广泛条件下,创造视觉亮度对比的要求是满足的。delaisi。
Since the discovery of red fluorescence in fish, much effort has been invested to elucidate its potential functions, one of them being signaling. This implies that the combination of red fluorescence and reflection should generate a visible contrast against the background. Here, we present in vivo iris radiance measurements ofTripterygion delaisiunder natural light conditions at 5 and 20 m depth. We also measured substrate radiance of shaded and exposed foraging sites at those depths. To assess the visual contrast of the red iris against these substrates, we used the receptor noise model for chromatic contrasts and Michelson contrast for achromatic calculations. At 20 m depth,T. delaisiiris radiance generated strong achromatic contrasts against substrate radiance, regardless of exposure, and despite substrate fluorescence. Given that downwelling light above 600 nm is negligible at this depth, we can attribute this effect to iris fluorescence. Contrasts were weaker in 5 m. Yet, the pooled radiance caused by red reflection and fluorescence still exceeded substrate radiance for all substrates under shaded conditions and all butJania rubensandPadina pavoniaunder exposed conditions. Due to the negative effects of anesthesia on iris fluorescence, these estimates are conservative. We conclude that the requirements to create visual brightness contrasts are fulfilled for a wide range of conditions in the natural environment ofT. delaisi.
