We report observational evidence that the blue luminosity function depends on the local density of galaxies. While high luminosity galaxies are segregated to the high density regions, low luminosity ones are more diffusely distributed into regions of lower density contrast. This segregation, also seen in other properties such as surface brightness, supports the predictions of theories of biased galaxy formation and argues against the validity of a universal luminosity function (LF) for galaxies.
