The concept of 'ecological resilience' has gained prominence in environmental science, referring to an ecosystem's capacity to absorb disturbance and reorganize while undergoing change so as to retain essentially the same function, structure, identity, and feedbacks. Unlike mere stability, which implies a return to a pre-disturbance state, resilience emphasizes adaptability and transformation. For instance, a coral reef that experiences bleaching may recover to a similar state if stressors are reduced, but if resilience is low, it may shift permanently to an algal-dominated system. This shift represents a regime change, where the ecosystem crosses a threshold into a new state that is often difficult to reverse. Understanding these dynamics is crucial for effective conservation, as management strategies must focus on enhancing resilience rather than simply resisting change.
❓ Según el pasaje, ¿cuál es la diferencia clave entre la resiliencia ecológica y la estabilidad?
A. La resiliencia se centra en volver al estado original, mientras que la estabilidad permite la transformación.
B. La estabilidad implica un retorno a un estado previo a la perturbación, mientras que la resiliencia enfatiza la adaptabilidad y la transformación.
C. La resiliencia solo se aplica a los arrecifes de coral, mientras que la estabilidad se aplica a todos los ecosistemas.
D. La estabilidad es un concepto moderno, mientras que la resiliencia se ha utilizado durante siglos.
✅ 正确答案
Stability implies a return to a pre-disturbance state, whereas resilience emphasizes adaptability and transformation.
