Competition in a rough neighborhood: Plant success in a desert environment

In deserts, variable weather is common so that plant community patterns can change between wet and dry years, with high densities and a diversity of plants in wet years, and a reduction in both quantity and number of species in dry years. The effect that two important variables have on plant communities — competition and water usage — was investigated in the Sonoran Desert by a research group at the University of Arizona.
