...Naomi F. Green; Emily Guevara; Daniel C. Osorio; John A. Endler; N. Justin Marshall; Misha Vorobyev; Karen L. Cheney ABSTRACT Animals use colour vision in a range of behaviours. Visual performance is limited by thresholds, which are set by noise in photoreceptors and subsequent neural processing...
