The effect of visual obstructions on the sexual behaviour of guppies Essay

The pith of visual obstructions on the sexual behaviour of guppies - canvass ExampleTherefore, in order to gain a better understanding of the evolution of specific, elaborate secondary coil sexual characteristics, it is important to study the ecological factors and behavioral mechanisms that may influence the come out of the closetcome of sexual selection. These changes may therefore affect the evolutionary outcome of sexual selection. This paper summarizes the published article by Hibler and Houde entitle The effect of visual obstructions on the sexual behavior of guppies the importance of privacy.The research team examined the effect of habitat structure on the sexual behavior of manlike and female guppies, Poecilia reticulata. The team tested whether the readiness of males to observe the courtship activities of other males affects the frequency of courtship haphazardness by male guppies, and whether this in patch affects the sexual behavior of virgin females interacting w ith these males. They tested these predictions by manipulating the structure of guppy habitats in the laboratory employ opaque barriers and observing the effect of such visual obstructions on male courtship and interference behavior, as well as on female sexual responsiveness to male appearances in experimental groups of guppies.The results of the experiments were scored and the interference behaviors as either fend-offs or chases. Data for male groups that were tested with both virgin and non-virgin females were analyzed victimization ANOVA to determine the effect of both treatment and reproductive status (virgin versus non-virgin) on male display and interference behaviors with male group as a blocking factor. For trials involving non-virgin females, ANOVAs containing an order effect were also carried out for chases, fend-offs and displays.The results of this study support the original predictions made by the study group that visual obstructions reduce male interference behavior and increase female responsiveness
