Cоrаl bleаching is оne оf the most visible consequences of globаl climate change and oceanic stress. Explain the biological mechanisms underlying coral bleaching, including the relationship between corals and their symbiotic zooxanthellae. Discuss how abiotic stressors such as temperature rise, ocean acidification, and pollution contribute to bleaching events. Finally, evaluate the ecological and evolutionary consequences of large-scale bleaching for marine biodiversity, and propose potential strategies, both biological and environmental, that could promote coral recovery and long-term reef resilience.
