Bar plots corresponding to ratios of final abundances of different species relative to initial abundance at the onset of drifting. Initial abundances are seen in columns two and three in Table 1, and the radii at which final abundances are read out of the simulation are seen in column four in Table 1. The y-axis indicates the ratios of these values, for the six different permutations of modelling setup (on the x-axis). Drift time increases (drift becomes slower) going from left to right in each panel. We note that species which encounter their icelines further out (see Fig. 2), will experience less drifting time to change their initial abundances than will species with icelines further in. Top and middle rows have linear j/-axes, bottom row has logarithmic y-axis. We note that all y-axes feature different dynamical scales.
