The flow of dissolved organic material, such as soil, […]

University of Pennsylvania biologist Katie Barott and colleagues found that corals maintain their ability to resist bleaching even when transplanted to a new reef. Credit: S. Matsuda Corals that withstood a severe bleaching event and were transplanted to a different reef maintained their resilient qualities, according to a new study […]

Charles Darwin, the British naturalist who championed the theory of evolution, noted that corals form far-reaching structures, largely made of limestone, that surround tropical islands. He didn’t know how […]

In recent years, advancements in DNA sequencing have exposed a large amount of hidden diversity in reef-building […]

Plankton-feeding fishes often dominate the fish assemblage on oceanic coral reefs. Credit: Dr. Christina Skinner Study reveals open ocean waters once assumed to be unproductive are in fact teeming with an abundance of life on coral reefs. Since Charles Darwin’s day, the abundance of life on coral reefs has been […]

Māori wrasse are large, colorful fish that can be found on the Great Barrier Reef. In a ground-breaking new study, scientists used innovative molecular techniques to explain how corals on the east coast of Australia survived previous tough conditions—enabling the Great Barrier Reef to become the vast reef it is […]

Montastraea spawning, Philippines. Credit: James R. Guest Efforts to understand when corals reproduce have been given a boost thanks to a new resource that gives scientists open access to more than forty years’ worth of information about coral spawning. Led by researchers at Newcastle University, UK, and James Cook University, […]

Bhattacharya 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 […]

Coral reefs, such as Los Jardines de la Reina, pictured, have microbes that may help protect the coral against certain nutrient imbalances. Credit: Robert Walker The bacteria scrub out nitrogen, potentially defending against certain nutrient overloads. Corals have evolved over millennia to live, and even thrive, in waters with few […]
