How to identify heat-stressed corals

Researchers have found a novel way to identify heat-stressed corals, which could help scientists pinpoint the coral species that need protection from warming ocean waters linked to climate change, according to a Rutgers-led study. “This is similar to a blood test to assess human health,” said senior author Debashish Bhattacharya, a Distinguished Professor in the […]

Could key gene system discovery be suffocating corals’ last gasp?

A unique stress experiment aligned deoxygenation stress to the natural night-day cycle of common reef-building corals from The Great Barrier Reef.

While the […]

Deep-sea corals reveal secrets of rapid carbon dioxide increase as the last ice age ended

Researchers examined deep-sea coral fossils – species Desmophyllum dianthus – to study carbon sequestration in the Southern Ocean 20,000 to 10,000 years ago. The chemical signatures of nitrogen and carbon in the coral fossils revealed that ocean carbon sequestration decreased as phytoplankton failed to devour macronutrients supplied by upwelling currents in the Southern Ocean and […]

Are corals genetically equipped to survive climate change? — ScienceDaily

In 1998, ocean temperatures soared, and the world experienced its first significant coral bleaching event. From the Great Barrier Reef to Indonesia to Central America, corals turned white and ghostly. Many of them died. And this was just a hint as to what was to come. Over the following two decades, the bleaching became more […]
