Disperal project simulation  (program download .zip format)

Simulating dispersal over many scales is problematic. By keeping track of individuals and not empty space, flexible programs can be written which make it possible to examine patterns of populations in space. The program downloadable here implements this approach behind a graphic interface. When you start the program, the space will be empty. As "Go" (or "run" and "redraw") are pressed repeatedly, a population develops through birth, death and dispersal, and it is possible to see patterns developing at many scales - zoom the screen.

Different dispersal patterns characteristic of wind (power-law or cauchy) and splash or random walks (exponential, zawolek) can be compared, and tools are provided for statistical analysis of the resulting near fractal patterns.
