Evolution of the fractional contribution of the early-type/red galaxies to the global MFs in low and high density environments from the surveys SDSS, zCOSMOS, and DEEP2. In the low redshift bin, red and blue lines are computed from Eq. (10) by Baldry et al. (2006), representing the fraction of red galaxies in the highest and lowest environmental densities in their SDSS analysis. In the other redshift bins, red solid lines and filled squares represent the zCOSMOS high-density sample D4, and blue long-dashed lines and filled circles the low-density sample D1. Orange and cyan lines and empty symbols represent the values of the analogous fractions taken from Bundy et al. (2006). The vertical dashed lines mark ℳ_min in zCOSMOS, and vertical dotted lines represent the K_s-band completeness limits in Bundy et al. (2006). Redshift ranges between brackets refer to DEEP2 binning.
