Query: Disturbance accelerates the transition from low- to high- diversity
  state in a model ecosystem   The effect of disturbance on a model ecosystem of sessile and mutually
competitive species [Mathiesen et al. Phys. Rev. Lett. 107, 188101 (2011);
Mitarai et al. Phys. Rev. E 86, 011929 (2012) ] is studied. The disturbance
stochastically removes individuals from the system, and the created empty sites
are re-colonized by neighbouring species. We show that the stable
high-diversity state, maintained by occasional cyclic species interactions that
create isolated patches of meta-populations, is robust against small
disturbance. We further demonstrate that finite disturbance can accelerate the
transition from the low- to high-diversity state by helping creation of small
patches through diffusion of boundaries between species with stand-off
relation.
