How microbes reflect the health of coral reefs

A collaborative study compared seawater from 25 reefs in Cuba and the U.S. Florida Keys varying in human impact and protection, and found that those with higher microbial diversity and lower concentrations of nutrients and organic carbon—primarily caused by human activities—were markedly healthier.

Climate change threatens everyone’s favorite little fish

Cape Cod Times

The well-being of the colorful clownfish of “Finding Nemo” fame is closely tied to its habitat among the sea anemone, according to a 10-year study by an international team of scientists. The little fish does not appear to have the ability to adapt to the rapid environmental effects of climate change.

Virgin Island Corals in Crisis

A coral disease outbreak that wiped out nearly 80% of stony corals between Florida’s Key Biscayne and Key West during the past two years appears to have spread to the U.S. Virgin Islands (U.S.V.I.), where reefs that were once vibrant and teeming with life are now left skeleton white in the disease’s wake.

When most people think of corals, they think od the big interconnected structures such as the Great Barrier Reef off Australia. But deep in the ocean much smaller coral formations lie past the point where light penetrates.

To investigate coral bleaching, WHOI scientists figure out a novel way to take direct measurements in the ocean of superoxide, a key molecule that vanishes almost as soon as it is made.

Coral Larvae Use Sound to Find a Home on the Reef

Coral Larvae Use Sound to Find a Home on the Reef

Choosing a place to call home is one of the most consequential choices a coral can make. In the animal’s larval stage, it floats freely in the ocean, but once it settles down, it anchors itself permanently to the rocky substrate of a reef, and remains stuck there for the rest of its life. Exactly how these larvae choose a specific place to live, however, is largely unclear.

Study Tracks Severe Bleaching Events on a Pacific Coral Reef Over Past Century

Study Tracks Severe Bleaching Events on a Pacific Coral Reef Over Past Century

As climate change causes ocean temperatures to rise, coral reefs worldwide are experiencing mass bleaching events and die-offs. For many, this is their first encounter with extreme heat. However for some reefs in the central Pacific, heatwaves caused by El Nino are a way of life. Exactly how these reefs deal with repeated episodes of extreme heat has been unclear. A new study from the Woods Hole Oceanographic Institution (WHOI), has uncovered the history of bleaching on a reef in the epicenter of El Nino, revealing how some corals have been able to return after facing extreme conditions. The study was published October 26, 2018, in the journal Communications Biology.
