http://dbpedia.org/ontology/abstract Na ecologia, a teoria dos estados estáveisNa ecologia, a teoria dos estados estáveis alternativos prevê que os ecossistemas podem existir sob múltiplos "estados" (determinados por conjuntos de condições bióticas e abióticas únicas). Esses estados alternativos não são transitórios e, por isso, são considerados estáveis em escalas de tempo ecologicamente relevantes. A partir de uma perturbação, os ecossistemas podem fazer a transição de um estado estável para outro. Devido aos feedbacks ecológicos, os ecossistemas apresentam resistência às mudanças de estado e, portanto, tendem a permanecer em um estado, a menos que as perturbações sejam grandes o suficiente. Vários estados podem persistir em condições ambientais iguais, um fenômeno conhecido como histerese. A teoria dos estados estáveis alternativos sugere que os estados são separados por limites ecológicos, em contraste com os ecossistemas que mudam ao longo de um gradiente ambiental. mudam ao longo de um gradiente ambiental. , In ecology, the theory of alternative stabIn 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 ecologically-relevant timescales. Ecosystems may transition from one stable state to another, in what is known as a state shift (sometimes termed a phase shift or regime shift), when perturbed. Due to ecological feedbacks, ecosystems display resistance to state shifts and therefore tend to remain in one state unless perturbations are large enough. Multiple states may persist under equal environmental conditions, a phenomenon known as hysteresis. Alternative stable state theory suggests that discrete states are separated by ecological thresholds, in contrast to ecosystems which change smoothly and continuously along an environmental gradient.tinuously along an environmental gradient.
