WebJul 25, 2011 · For example, as apparent in our results, the number of alternative stable states may be determined solely by the strength of plant-soil feedback, whereas the number of alternative transient states may be determined not only by the strength of feedback, but also by other factors such as mortality rate and environmental heterogeneity. 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.

In this ecological context, hysteresis refers to the existence of different stable states under the same variables or parameters. Hysteresis can be explained by "path-dependency", in … See more Most work on alternative stable states has been theoretical, using mathematical models and simulations to test ecological hypotheses.
