Glowing corals discovered in the Red Sea

Corals that switch from green to deep red when exposed to ultraviolet light could provide a new toolkit for biomedical imaging.

Glowing world of rainbow corals found in the Red Sea

There’s a fluorescent disco world in the Red Sea. An assortment of glowing corals has been discovered more than 50 metres down, outshining the monotone green varieties seen in shallower waters.

Jörg Wiedenmann of the University of Southampton in the UK and his team were surprised to see specimens with a red or yellow glow at depths of over 50 metres. “This could only be due to the presence of fluorescent pigments,” says Gal Eyal of the Interuniversity Institute for Marine Sciences in Israel, a member of the team.

The lobed brain coral … changes colour from green to deep red when illuminated with ultraviolet light. Optical properties like this could be useful for biomedical imaging, for example to help highlight cell structures under a microscope, track cancer cells or screen new drugs.

Wiedenmann and his team want to find out why the corals produce the pigments. In shallow water, colours act as a sunscreen. But deeper down, where sunlight doesn’t penetrate, that can’t be the case. Yet the pigments must have a role since it takes a lot of energy to produce them.

The pigments might help the corals harvest energy from what little light is around, then feed it to symbiotic algae that provide them with energy-rich sugars. “The underlying mechanism is not understood,” says Wiedenmann. “Hopefully our future work can reveal their function.”

Corals also seem to be capable of other tricks. Although reefs are threatened by climate change, they are also able to put up a fight, sometimes evolving rapidly to adapt to their changing environment.

New Zealand scientists voice concern over gagging on climate change. WELLINGTON, June 22 (Xinhua) — New Zealand scientists said Monday that government funding policies have effectively prevented them from making any serious input into the government’s climate change stance: here.

Coral Restoration Foundation, Planting staghorn corals

5 October 2013

Ken Nedimyer talks about the Coral Restoration Foundation’s coral nursery and how they plant staghorn corals on the reefs of Key Largo, Florida.

From Wildlife Extra:

1,600 Corals planted at Florida Keys Plantapalooza

To celebrate World Oceans Day divers from the Florida Keys-based Coral Restoration Foundation has planted 1,600 corals in the Florida Keys National Marine Sanctuary. Some 70 divers sowed corals at six Upper Keys sites including Molasses Reef, Carysfort Reef, Grecian Rocks, Little Conch Reef, Snapper Ledge and Pickles Reef.

“It’s really important to get the corals out there in large amounts, but it’s also important because we’re involving a lot of the community,” said Kayla Ripple, the Coral Restoration Foundation’s coral nursery programme manager.

Staghorn corals are threatened, but Coral Restoration Foundation has had good success in cultivating and planting new staghorns where the species has died.

The small coral fragments were grown in a designated nursery about three miles from the Keys. The infant corals, about three inches long, are hung on a framework of PVC pipe resembling a tree to develop. After nine months, the staghorns typically reach the size of a dinner plate and are transported to offshore reefs where they are affixed to the sea floor with epoxy.

Since Coral Reef Foundation’s launch in 2000 the organisation has planted some 31,500 corals on upper and middle Keys reefs, however this is the organisation’s most prolific output in a single day.

Coral reef research, video

5 June 2015

A team of scientists from Khaled bin Sultan Living Oceans Foundation and XL Catlin Seaview Survey sets sail on the world’s largest coral reef expedition to gather ground-breaking images to reveal the reefs as never seen before.

The research vessel, M/Y Golden Shadow, was in the Solomon Islands conducting surveys for the Foundation’s Global Reef Expedition. The XL Catlin Seaview Survey science team, from the University of Queensland joined the Expedition and used their custom panorama camera system to take stunning 360⁰ imagery of the reefs. Over the course of 10 days, the team was able to document over 21 miles of reefs, all as part of an ongoing research project that aims to measure coral reef habitat diversity across the tropics and understand how coral reefs are changing due to human pressures.
