Data from: Diurnal lighting patterns and habitat alter opsin expression and colour preferences in a killifish

Ashley M. Johnson, Shannon Stanis & Rebecca C. Fuller
Spatial variation in lighting environments frequently leads to population variation in colour patterns, colour preferences and visual systems. Yet lighting conditions also vary diurnally, and many aspects of visual systems and behaviour vary over this time scale. Here, we use the bluefin killifish (Lucania goodei) to compare how diurnal variation and habitat variation (clear versus tannin-stained water) affect opsin expression and the preference to peck at different-coloured objects. Opsin expression was generally lowest at midnight...
