Modelling patch dynamics on rocky shores using deterministic cellular automata

Abstract

A model of biologically driven patchiness in the Fucus-limpet-barnacle mosaic on rocky shores was developed using deterministic cellular automata. The model is bas d on interconnected small areas of approximately 1 limpet foraging diameter (1 m). Five states are recognised, which represent stages in the natural cycle of development of patches: (1) dense barnacle cover with no limpets;
