What’s behind the retreating kelps and expanding corals?

Climate change and other external forces are causing rapid marine community shifts in Japan's coastal ecosystems. Better understanding of species distribution dynamics, as driven...

Corals are becoming more tolerant of rising ocean temperatures

The existence and causes of coral bleaching are recognized as an increasing world-wide environmental concern related to climate change. A number of experiments have...

First mapping of global marine wilderness shows just how little remains

Researchers reporting in the journal Current Biology on July 26 have completed the first systematic analysis of marine wilderness around the world. And what they found...

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...

Coral tricks for adapting to ocean acidification

A process that changes the regulation of genes could help corals acclimatize to the impacts of global warming. Cells commonly control gene expression by adding...

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...

New study highlights opportunity to restore abundance to reef fisheries

Unsustainable fishing has depleted coastal fisheries worldwide, threatening food security and cultural identity for many coastal and island communities, including in Hawai'i. A recently...

Excess nutrients damage the most highly resilient corals

Over the last 30 years, 50% of the world's coral reefs have suffered significant damage due to climate change and acidification with the last...

Balance of thermal energy and low climate stress drive coral species diversity

Marine scientists from WCS (Wildlife Conservation Society), University of Warwick, and University of Queensland have identified two key factors that create the ideal conditions...

Internal control helps corals resist acidification

Scientists from the ARC Centre of Excellence for Coral Reef Studies (Coral CoE) at The University of Western Australia (UWA) have found that some...

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...
