This study investigates the role of uv vision in mate choice in a teleost, the guppy (poecilia reticulata peters, 1859) although photons with wavelengths between approximately 400-700 nm excite the sensation of vision in humans ( campbell and dwek, 1984 ), many animals additionally perceive uv wavelengths in the range 300-400 nm ( tovée, 1995 ).

Experiments were designed to determine the effects of male pigmentation patterns on female choice in guppies when presented with a series of variably-colored males, females of different genetic female preference and sexual selection for male coloration in the guppy ( poecilia reticulata) | springerlink. One such species in which males contribute nothing but sperm during mating is the guppy (poecilia reticulata) here, we examined whether female guppies can obtain information on male fertility (ie, direct fertility benefits) via cues used during mate choice. Although male guppies (poecilia reticulata) contribute only sperm to their offspring, preliminary evidence points to male mate choice in this species thus, the hypothesis that male guppies choose their mates was investigated.

Mate choice has an effect on the fitness and mating strategy of a species, and fitness contributes to natural selection and which traits are carried on to future generations in a quest to study the sexual selection of male guppies, poecilia reticulata, we are working with the center for the study of sexual selection in fishes to measure the . In our experiments using the trinidadian guppy ( poecilia reticulata ), this reversal was mediated by mate-copying opportunities, such that a female (the ‘focal’ female) is given the opportunity to choose between two males, followed by a period in which she observes a second female (the ‘model’ female) displaying a preference for the .
