Amid fears for the world’s coral reefs, the UN World Heritage Committee has issued its most wide-ranging statement so far on protecting heritage sites from climate. But the problem doesn’t end there.

Plant-eating fish control the spread of seaweed and algae on coral reefs. New research explaining why populations of these fish vary from site to site could lead to better reef protection strategies.
Scientists assess coral deaths in the worst-affected part of the Reef in November 2016.

Two-thirds of the corals in the northern part of the Great Barrier Reef have died on in the reef’s worst-ever bleaching event, according to the latest underwater surveys.

The oceans are filled with sounds produced by animals. However, a recent study shows that ocean sounds are diminishing due to nutrient pollution and ocean acidification.
We think of coral reefs as a diverse ecosystem, but each coral is an entire and complex microworld of organisms imperceptible to our eyes.
