The concept of 'environmental resilience' has gained traction in ecological studies, referring to an ecosystem's capacity to absorb disturbances while maintaining its fundamental structure and functions. Unlike mere resistance, which implies a static defense against change, resilience involves dynamic adaptation. For instance, a coral reef that bleaches under thermal stress but subsequently recovers with a different species composition demonstrates resilience, not resistance. Recent research suggests that biodiversity plays a crucial role in enhancing resilience, as diverse communities are more likely to contain species capable of thriving under altered conditions. However, human-induced pressures, such as pollution and overexploitation, can erode this natural buffer, pushing ecosystems beyond their tipping points. Consequently, conservation strategies increasingly focus on preserving not just current states but the adaptive capacities of ecosystems, acknowledging that dynamic change is inevitable in the Anthropocene.
❓ Según el pasaje, ¿cuál es la diferencia clave entre la resiliencia y la resistencia en los ecosistemas?
A. A) La resiliencia implica una defensa estática, mientras que la resistencia implica una adaptación dinámica.
B. B) La resiliencia se refiere a la recuperación después de una perturbación, mientras que la resistencia significa soportar la perturbación sin cambios.
C. C) La resiliencia solo es aplicable a los arrecifes de coral, mientras que la resistencia se aplica a todos los ecosistemas.
D. D) La resiliencia reduce la biodiversidad, mientras que la resistencia la aumenta.
✅ 正确答案
B) Resilience refers to recovery after disturbance, while resistance means withstanding disturbance without change.
