An evaluation of video playback using Xiphophorus helleri
Article Abstract:
It appears that female preference for a male in green swordtails, Xiphophorus helleri, is an increasing function of sword length, according to research assessing the effectiveness of video playback as a way of measuring female mating preferences by comparing the response of female green swordtails to live and video stimuli. The same qualitative female response was achieved with both live and video presentations, but there seem to be differences between female response to live and video stimuli. Live presentations seem to elicit a higher level of female response than video presentations, and the strength of preference for sword length seems to be stronger.

Maleumale competition and the sword in male swordtails, Xiphophorus helleri
Article Abstract:
Research on Xiphophorus helleri swordtail fish populations shows that males with longer swords experienced a larger degree of competitive success in studies that controlled for body size. Implications for the evolutionary development of longer swords are also discussed.

Location, location, location: stripe position effects on female sword preference
Article Abstract:
Female Xiphophorus helleri swordtail fish were found to prefer males with distally black striped swords. Implications for further research on the role of multicomponent visual traits in mate choice are discussed.
