Immunity could be key to addressing coral crisis

Coral reefs support a quarter of all marine life, feed hundreds of millions of people and contribute vastly to the global economy. But they...

Frigid polar oceans, not balmy coral reefs, are species-formation hot spots

Tropical oceans teem with the dazzle and flash of colorful reef fishes and contain far more species than the cold ocean waters found at...

Marine reserves are vital — but under pressure

A massive study of nearly 1800 tropical coral reefs around the world has found that marine reserves near heavily populated areas struggle to do...

Coral reef ‘oases’ offer glimmer of hope

The identification of small 'oases' in the world's oceans, where corals appear to be thriving, could offer vital insights in the race to save...

Coral reefs losing ability to keep pace with sea-level rise

Many coral reefs will be unable to keep growing fast enough to keep up with rising sea levels, leaving tropical coastlines and low-lying islands...

Nutrient pollution makes ocean acidification worse for coral reefs

A study published recently by a team of researchers, alumni and students from the University of Hawai'i at Manoa School of Ocean and Earth...

Young fish no longer hear their way home

Degraded coral reefs are far quieter than five years ago, and no longer sound like a suitable habitat to young fish searching for a...

Are some reefs able to resist coral bleaching?

As scientists and conservationists race to work out the best way to conserve the world's coral reefs, a new study reveals why some reefs...

Great Barrier Reef corals can survive global warming for another century

Using genetic samples and computer simulations, evolutionary biologists have made a glass-half-full forecast: Corals in the Great Barrier Reef have enough genetic variation to...

Global warming is transforming the Great Barrier Reef

A new study published online in Nature shows that corals on the northern Great Barrier Reef experienced a catastrophic die-off following the extended marine heatwave of...

Coral bleaching threatens the diversity of reef fish

New research reveals that global warming also affects fish who depend on corals. The Great Barrier Reef (GBR) is revered for its kaleidoscope of colour....

How submarine groundwater affects coral reef growth?

Groundwater that seeps into the coastal zone beneath the ocean's surface--termed submarine groundwater discharge (SGD)--is an important source of fresh water and nutrients to...

A natural fertilizer

It's long been known that sharks help nourish coral reefs, but exactly to what extent has never been scientifically mapped out -- until now. A...

Coral reefs suffering despite outlawing damaging fishing practices

Some of the fishing methods used in today's small-scale fisheries are causing more damage to coral reefs than ever, a new UBC study has...

Ocean acidification from carbon dioxide slows coral growth

Ocean acidification will severely impair coral reef growth before the end of the century if carbon dioxide emissions continue unchecked, according to new research...
