📖 Reading Passage

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 an unchanging state, resilience emphasizes adaptability and recovery. For instance, coral reefs subjected to bleaching events may exhibit resilience if they can regenerate through the recruitment of new polyps or the survival of resilient symbionts. However, resilience is not infinite; excessive or frequent stressors can push systems past critical thresholds, leading to regime shifts where a new, often less desirable, equilibrium emerges. Understanding these dynamics is crucial for effective conservation, as it shifts focus from preventing all change to managing adaptive capacity and preserving options for future trajectories.
