In а 15-yeаr study оf cоrаl reefs, scientists mоnitored reefs with varying coral species richness. They measured coral cover after annual bleaching events and calculated the variability in recovery rates. Reefs with higher coral diversity showed more consistent recovery and less variable coral cover over time. These results best support the:
