紫外线（UV）视觉在许多脊椎动物物种中都有很好的记录。已知紫外线信号用于觅食、导航和择偶。我们进行了一系列的行为实验，以调查的作用，紫外线的感知在配偶选择的雌性和雄性孔雀鱼（孔雀鱼）。在我们的实验中，使用UV透射（UV+）或UV阻挡（UV-）过滤器操纵潜在配偶的视觉外观。雌性孔雀鱼明显更喜欢紫外线+男性。雄性孔雀鱼倾向于喜欢紫外线的雌性，但他们的偏好是微不足道的。进一步的实验调查亮度的作用，表明紫外线波长可能被用于颜色的歧视，而不是用于检测亮度的差异。这些实验提高了雄性和雌性孔雀鱼以不同方式使用紫外线进行配偶评估的可能性。这可能反映了两性为了最大限度地提高繁殖成功率而采取的不同策略。据我们所知，这是第一次有数据表明，紫外线是任何鱼类在择偶时使用的。版权所有2002年。
Ultraviolet (UV) vision is well documented for many species of vertebrates. UV cues are known to be used in foraging, navigation and in mate choice. We conducted a series of behavioral experiments to investigate the role of UV perception in mate choice in both female and male guppies (Poecilia reticulata). In our experiments the visual appearance of potential mates was manipulated using either UV transmitting (UV+) or UV blocking (UV-) filters. Female guppies significantly preferred UV+ males. Male guppies tended to prefer UV- females, but their preferences were marginally nonsignificant. Further experiments investigating the role of luminance, indicate that UV wavelengths are probably being used for color discrimination rather than for detecting differences in brightness. These experiments raise the possibility that UV is used in mate assessment in different ways by male and female guppies. This may reflect the different strategies that the two sexes have in order to maximize reproductive success. To our knowledge, these are the first data showing that UV is used by any fish species in mate selection. Copyright 2002.
