A few hints about the ecological problem and the Incidence Function Model (IMF)

A few hints about the ecological problem and the Incidence Function Model (IFM) - Page 4/6

The IFM relates the extinction probability of a patch to its area: the larger the patch the lower the extinction probability, as indicated in Figure 6 by different thickness of the red arrows.

Figure 6 – At time t +1, any occupied patch could go extinct. The larger the patch the lower the extinction probability: in this picture this fact is marked by the different thickness of the arrows of two extinct populations: the thicker the red arrow, the higher the extinction probability.
