Example of alternative stable states
WebNov 12, 2015 · Although in evolution there is no way back to demonstrate hysteresis, such new states can often be seen as alternative stable states. For example, the great oxygenation event, about 2·4 billion years ago, was the result of the emergence of photosynthesis interacting with a positive feedback in atmospheric chemistry leading to … WebJun 30, 2016 · The theory of alternative stable states (Scheffer and others 2001) predicts that bistable systems can undergo a transition from one state to the other if environmental conditions (such as MAP) reach a so-called ‘tipping point.’

In ecology, the theory of alternative stable states (sometimes termed alternate stable states or alternative stable equilibria) predicts that ecosystems can exist under multiple "states" (sets of unique biotic and abiotic conditions). These alternative states are non-transitory and therefore considered stable over … See more Alternative stable state theory was first proposed by Richard Lewontin (1969), but other early key authors include Holling (1973), Sutherland (1974), May (1977), and Scheffer et al.
