(par 3.10.3) Resilience (from wikipedia)
http://en.wikipedia.org/wiki/Main_Page From Wikipedia, the free encyclopedia Lake and Mulga ecosystems with alternative stable states[1] In ecology, resilience is the capacity of an ecosystem to respond to a perturbation or disturbance by resisting damage and recovering quickly. Such perturbations and disturbances can include stochastic events such as fires, flooding, windstorms, insect population explosions, and human activities such as deforestation and the introduction of exotic plant or animal species. Disturbances of sufficient magnitude or duration […]
