UV reflectance in poison frog

We have identified strong UV reflectance in the white spots of only a single population of the polymorphic/polytypic poison frog species Oophaga sylvatica. As congeners (O. pumilio) are unable to view UV signals, it stands to reason that natural selection, or neutral processes are likely to be responsible for these signals. We employ visual modeling techniques to estimate the perception of these UV signals, and in a series of comparisons we show surprisingly minimal gains in frog contrast due to their addition.
