Upper panel: Evolving stellar mass function toy model as described in Section 4.1 (solid lines) at different redshifts, compared to those from SDSS (grey dots and error bars) at |$z=0.1$| from Bernardi et al. (2017). Lower panel: Stellar mass–halo mass relation computed via abundance matching for the evolving stellar mass function model in the range of redshift denoted by the colour code, compared to the relation at |$z=1$| implied by the constant stellar mass function (red dashed line).
