Metapopulations & Patch Simulations -- Levins Model
by Mike Martin

This page generates a plot of the percentage of occupied patches by a metapopulation and a plot of the percentage of unoccupied patches of a metapopulation. This particular model for metapopulations and their occupation of patches is due to Levins.   Consider a percentage of occupancy, p, that changes at a rate given by

The parameter c is a colonization factor and the parameter e is an evacuation factor.   Enter the value of these parameters, the time bound, and the initial percentage, p (0) = po.

Enter in the values of the non-negative parameters c, e, po, and select the plotting bound, then press the "Evaluate" button.
