Figure 4. The number of individuals moving between populations (the flux) as defined by the offset gravity model (low, medium and high mobility and the LHS models) and for comparison the radiation model.

We illustrate the mobility models at three resolutions: A: highest resolution, B: medium resolution and C: low resolution. The highest mobility model has higher average flux compared to the low and medium mobility models. At lower resolutions and high mobility large numbers of individuals move, but the distribution of the numbers moving is more uniform than at the highest resolution, causing the lines for the three mobility scenarios to swap order at different resolutions.
