A recent study published in a major science journal has yielded some fascinating results about marine ecosystems. Researchers found that certain types of coral reefs can recover from bleaching events much faster than previously thought, but only under specific conditions. One key factor is the presence of herbivorous fish, which graze on algae that would otherwise smother the young coral. This highlights the delicate interconnectedness of species within an ecosystem. Without these fish, recovery is significantly slower.
