Coral Reefs

A new study has cast doubt on the extent to which mesophotic reefs may be a refuge for shallower species hit by overfishing, warming waters, and extreme weather.

Gun deaths in the U.S. hit a 20-year high, the Supreme Court declines to wade into an abortion debate, and a study offers some hope for coral reefs.

But scientists are having a hard time illustrating these problems as shifting baselines continue to redefine what is considered normal for reef health.

Australian scientists now report that coral cover on the Great Barrier Reef has fallen sharply in all three sections of the reef for the first time in 35 years of continuous monitoring.

New research finds that the biomass of the entire fish community was nearly 50 percent larger around the rat-free islands.

According to a recent study, losing just the top three feet of coral reef could result in $4 billion a year in flood-related damages.

An innovative monitoring system would allow researchers, policymakers, and environmentalists to track reef damaging events across the globe in near-real time.

Lionfish are non-native invaders introduced to Florida waters 30 years ago that have since proliferated to pestilent levels and unleashed an ecological crisis that is only getting worse

Highlighting the mess humans have made of the planet—and radical plans to fix it.

Heat-tolerant genes may spread through coral populations fast enough to give the marine creatures a tool to survive another 100 years of warming in our oceans.

As a result of rising ocean temperatures coral bleaching is becoming more common, and it's causing a biotic homogenization of local fish populations.

New research shows the extent to which our dependence on plastic is infecting, damaging, and killing coral reefs from Thailand to Australia.

Experts are hoping that new captive breeding programs, replacing harmful fishing practices, could help prevent future harm to coral reef ecosystems.

A new study shows that coral bleaching events are recurring faster than reef ecosystems can recover.

It appears that dust blown off the Sahara desert may be initiating harmful bacteria growth in coral reefs across the Atlantic.

The technique involves planting fragments of nursery-raised coral on reefs in the wild to replenish depleted colonies.

Raja Ampat, an island chain off the coast of New Guinea, is home to perhaps the world's richest marine biodiversity

Coral ecosystems around the globe are collapsing thanks in large part to human activities. How far should we go to save them?

Given the dual threats of climate change and increased tourism, conservationists are attempting to gather all the data they can before it’s too late.

El Niño storms seem to be strengthening due to climate change, and in turn intensifying coral bleaching. This is particularly vivid at Christmas Island, where the water has warmed the most.

In 2011, 1,000 times more tourists visited Roatán than in 1969.

As an old embargo lifts, a new vacation spot emerges.

New research shows that it will take decades for protected reefs to bounce back, but even minor fishing restrictions can have significant benefits for marine ecosystems.
