Population differentiation in the swordtail characin (Corynopoma riisei ): a role for sensory drive?

Journal of evolutionary biology - 1 Sept 2010

Arnqvist G, Kolm N

Abstract excerpt

Sensory drive, where the efficacy of a sexual signal depends on the environment in which it is employed, is a potential mechanism behind divergent evolution of secondary sexual traits. Male swordtail characins are equipped with a narrow and transparent extension of the gill cover with a flag-like structure at its tip. This opercular flag mimics a prey item and is employed by males as a 'lure' to attract the...
