Visual habitat geometry predicts relative morph abundance in the colour-polymorphic ornate rainbowfish.

Abstract excerpt

During colour signalling in aquatic environments, the colour of the ambient light, the background against which signals are viewed and signal transmission through the environment can all have profound impacts on the efficacy of a given signal. In colour-polymorphic species, where alternative morphs persist owing to a balance in the natural and sexual selection for each, changes to the visual context can have...
