- Variable vision in variable environments: the visual system of an invasive cichlid (Cichla monoculus) in Lake Gatun, Panama
Summary: Examination of the visual system plasticity of the peacock bass, Cichla monoculus, shows that this species adapts to a changing environment by alternating the use of chromophores A1 and A2, and through differential gene expression in the retina.
