Protection by dead coral skeletons could theoretically help young coral, if new recruits settle on the reef shortly after a bleaching event.

The intricate, hidden processes that sustain coral life are being revealed through a new microscope developed by scientists ...

Tropical coral reefs encrust the coastlines of islands and continents near Earth’s equator but this zone, which has offered sufficient light and warmth for corals to evolve over hundreds of millions ...

Fossils found in northern Africa and Germany suggest that many of their relatives were already living with symbiotic algae in the Devonian Period, which lasted from 419 to 359 million years ago. The ...

What is coral bleaching? Dive in to learn all about this tipping point in our natural world and what you can do to help.

Discover how an algae-based gel enhances coral restoration by attracting larvae to damaged reefs, increasing settlement rates by up to 20 times.

University of Hawaii researchers said ground water flowing into the ocean at just the right amount can boost the growth of ...

To survive, coral and their algae maintain a tight relationship, but when ocean water gets too hot, the algae often jump ship, leaving just the white coral skeleton behind, a phenomenon called ...

A new handheld microscope lets scientists monitor coral health in real time, underwater, without harming reefs.

Prolonged warmth causes the algae to release toxic compounds, and the coral eject them. A stark white skeleton is left behind, and the weakened coral is at heightened risk of dying.

Algae grow faster than coral, so without the balancing effect of herbivory they can easily overrun a reef, preventing new corals from settling and shading out those colonies that do.
