MSR for quiescent galaxies in different redshift bins for the HD (top left) and LD (bottom left) environments, and α (top right) and log(A) (bottom right) as a function of redshift for the HD (red) and LD (orange) environments. The fitted evolutionary trends are shown as red dashed and orange dotted lines. The data showing the evolution of α and log(A) between LD and HD are shown with a slight offset to make the errorbars visible.
