corals may need a dose of C

Newly settled mustard hill corals use vitamin C when building their exoskeletons, new research shows.

New research found that when free-floating larvae settle and calcify their skeletons genes associated with vitamin C transport kick on. Without enough C they may even get scurvy. While the process of calcification is not fully understood, Joshua Rosenthal of the University of Puerto Rico and colleagues measured which genes switched on when mustard hill corals (Porites astreoides) transitioned out […]

For the first time lab grown corals have integrated and reproduced with with a wild population. In 2011 SECORE (SExual COral REproduction) reared endangered elkhorn coral from field collected gametes and then replanted them in 2012. Four years later these corals have grown to soccer ball size and reproduced, simultaneously with the natural population. “This event marks the first ever successful […]

The new NASA campaign CORAL, short for COral Reef Airborne Laboratory, will work to assess the condition coral reef ecosystems. They will collect data on the size and quality of the reefs using airplanes and water instruments striving to capture the most detailed views ever of the planet’s corals.  The researchers will visit the Great Barrier Reef, other reefs in Australia, along with reefs in Florida, Hawaii, […]

creating super corals

Ruth Gates of the Hawai’i Institute of Biology is working on breeding “super corals” that can withstand the warming that oceans are already experiencing while another Australian group is creating “mutt” corals from different robust species to gain the same result. And they are doing it by taking an approach similar to land-based genetic tinkering that has been going on […]
