Before revision:  Alternative theories show that the same sequence of patterns could emerge when interactions between plants are always inhibitory if their intensity decays sharply enough with inter-individual distance .
After revision:  These theories predict a sequential change in pattern shape from gapped to labyrinthine to spotted spatial patterns as precipitation declines. Nonetheless, alternative theories show that the same sequence of patterns could emerge when interactions between plants are always inhibitory if their intensity decays sharply enough with inter-individual distance .
