There is an increasing recognition that patterns in species diversity cannot be understood without reference to nonequilibrial or unstable dynamics. Recently, through a realistic ecological model that involves dispersal, we have addressed the positive role of noise in promoting species coexistence [Phys. Rev. Lett. 94, 038102 (2005)]. Here we present a physical theory to account for the main scaling law responsible for this phenomenon.
