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.
❓ 지문에 따르면, 생태계에서 회복탄력성과 저항성의 핵심 차이는 무엇인가?
A. A) 회복탄력성은 정적인 방어를 포함하는 반면, 저항성은 동적인 적응을 포함한다.
B. B) 회복탄력성은 교란 후 회복을 의미하는 반면, 저항성은 변화 없이 교란을 견디는 것을 뜻한다.
C. C) 회복탄력성은 산호초에만 적용되는 반면, 저항성은 모든 생태계에 적용된다.
D. D) 회복탄력성은 생물다양성을 감소시키는 반면, 저항성은 이를 증진시킨다.
✅ 正确答案
B) Resilience refers to recovery after disturbance, while resistance means withstanding disturbance without change.
