5.18 the SIMMAP neutral landscape model

This model implements the SIMMAP process for generation of neutral landscapes as described in

Saura S and Martinez-Milan J 2000 Landscape pattern simulation with a modified random clusters method. Landscape Ecology, 15, 661-677.

This model also requires a text file to configure the relative proportions of each class of landscape that it will produce. This file should not be renamed, and should be placed in the same folder as the model file.

The first line of this file indicates the number of different landscape classes required. Subsequent lines indicate for each required class the desired relative proportion of the landscape that it should occupy. If the model’s percolation parameter is set too high, then it may be very difficult for the model to produce landscapes with proportions close to the requested levels.

3.9 voter model with dispersal and mutation

This model implements a simple voter model with two non-local processes. One admits succession at a distance, while the other (mutation) allows the appearance of completely new states in the lattice.

3.8 simple voter model

This model is an implementation of a simple voter model.

The video demonstrates how regions of each original class or type develop and persist.
