Aussie coral reefs under threat, but toughing it out

Coral reefs in the Indo-Pacific region, including the Great Barrier Reef, recover faster from major stresses than their Caribbean counterparts.

The main reason that Indo-Pacific reefs are more resilient is they have less seaweed than the Caribbean Sea.

Seaweed and corals are age-old competitors in the battle for space. When seaweed growth rates are lower, such as the Indo-Pacific region, the reefs recover faster from setbacks.
