Coral reefs could disappear entirely from the Coral Triangle region of the Pacific Ocean by the end of the century, threatening the food supply and livelihoods for about 100 million people, according to a new study from World Wildlife Fund.

Results of a new study shed light on how threats to the world's endangered coral reef ecosystems can be more effectively managed.

When coral colonies meet one another on the reef, they have two options: merge into a single colony or reject each other and aggressively compete for space. Now, a report in the March 19th Current Biology, a Cell Press publication, has found a gene that may help to decide that fate.

By combining data from 48 studies of coral reefs from around the Caribbean, researchers have found that fish densities that have been stable for decades have given way to significant declines since 1995. The study appears online on March 19th in Current Biology, a Cell Press publication.

Scientists identified seven new species of bamboo coral discovered on a NOAA-funded mission in the deep waters of the Papahānaumokuākea Marine National Monument.

Coral reefs around the world are in serious trouble from pollution, over-fishing, climate change and more. The last thing they need is an infection. But that's exactly what yellow band disease (YBD) is—a bacterial infection that sickens coral colonies.

Tropical oceans are known as the deserts of the sea. And yet this unlikely environment is the very place where the rich and fertile coral reef grows. Dutch researcher Jasper de Goeij investigated how caves in the coral reef ensure the reef’s continued existence. Although sponges in these coral caves take up a lot of dissolved organic material, they scarcely grow. However, they do discard a lot of cells that in turn provide food for the organisms on the reef.

A team of scientists from the New York-based Wildlife Conservation Society (WCS) has reported a rapid recovery of coral reefs in areas of Indonesia, following the tsunami that devastated coastal regions throughout the Indian Ocean four years ago today.

Imagine descending in a submarine to the ice-cold, ink-black depths of the ocean, 800 metres under the surface of the Atlantic. Here the tops of the hills are covered in large coral reefs. NIOZ-researcher Furu Mienis studied the formation of these unknown cold-water relatives of the better-known tropical corals.

Rising carbon dioxide levels in the world’s oceans could deliver a disastrous blow to the ability of coral reefs to withstand climate change.

For endangered coral reefs, not all plant-eating fish are created equal.

When reef fish get a mouthful of sand, coral reefs can drown.
