A new study provides insight into coral-dwelling microbial communities and how they react to pollution, overfishing, and climate change. What does it mean for the Great Barrier Reef?
Nice to see you: parrotfishes prey on seaweed, which consume seaweeds that can outcompete, smother or even poison corals.

A combination of factors – pollution, disease and overfishing – is harming corals but scientists have found clues to effective treatment by studying corals’ microbiome.

Banning fishing helps fish, but it also helps reef recover from cyclones, disease, and coral bleaching.
Outbreaks of crown-of-thorns starfish, which eat coral, have been linked to poor water quality.

By artificially going ‘back in time’ to more alkaline ocean conditions, researchers have shown the damage that ocean acidification is already doing to the Great Barrier Reef.

Scientists say they’ve answered a long-held question of Darwin’s on why islands are so productive – an important step toward planning protections against the effects of climate change.

We’re going to have to adapt to climate change, but some of the options on the table could do more harm than good if they destroy the ecosystems that protect us.
The land may be dry, but Western Australia’s waters are full of life.

The Great Barrier Reef might get all the attention, but what about our western coral reefs? Warmer waters and human impacts mean these reefs are in trouble.
Scuba diving must be done in a sustainable manner to preserve the industry.

Africa has a number of excellent scuba diving sites, but these must be maintained sustainably to keep attracting different divers.

Many corals can’t make it through the bleaching events caused by warming ocean waters. But some can – and scientists are trying to learn more about the sources of their resilience.
