Which factor is crucial when selecting coral species for restoration based on climate models?

The selection of coral species for restoration projects is fundamentally influenced by their resilience to changing conditions, which is critical given the current climate crisis. Resilience refers to the ability of coral species to adapt and survive under various stressors, such as rising sea temperatures, ocean acidification, and changing salinity levels. Species that exhibit higher resilience tend to have physiological traits that allow them to withstand these environmental changes more effectively, making them better candidates for restoration efforts.

By focusing on species that can endure and thrive in a rapidly changing climate, restoration initiatives can increase the likelihood of establishing stable and healthy coral populations over the long term. This approach not only supports biodiversity but also contributes to the overall health of marine ecosystems. While other factors like cost, aesthetic value, and growth speed may be important in different contexts, they do not address the fundamental challenges posed by climate change, which is the primary concern in coral restoration today.
