文摘
We present a percolation model of a growing plant. Some parts of the organism stop by rooting, while others move on by horizontal growth and branching. We describe a new kind of threshold, pt, that is higher than the classical percolation threshold. Below pt, the plant cannot track along the pathways of suitable habitat. The demonstrated “labyrinth effect” is a considerable factor in the self-organization of plant communities.
