Australia's Great Barrier Reef Gets A Little Help From Volcanic Eruptions
2012-07-20 06:50:48

redOrbit Staff & Wire Reports - Your Universe Online Have you ever wondered how the Great Barrier Reef came to be? Research conducted by Queensland University of Technology geologist Dr Scott Bryan indicates that volcanic activity in the Southwest Pacific could help to save the Great Barrier Reef, but it could also be what caused it to form in the first place. Dr Bryan and colleagues studied the westward flow or rafting of pumice after volcanic eruptions in Tonga in 2001 and...

Scientists have discovered two viruses that appear to infect the single-celled microalgae that reside in corals and are important for coral growth and health, and they say the viruses could play a role in the serious decline of coral ecosystems around the world. These viruses, including an RNA virus never before isolated from a coral, have been shown for the first time to clearly be associated with these microalgae called Symbiodinium. If it's proven that they are infecting those algae and...

We Can Still Save Our Reefs

redOrbit Staff & Wire Reports - Your Universe Online John Pandolfi, along with 81 nations and 500 million people, keep hopeful that the world´s coral reefs are not in a lot of trouble. The world-famous coral scientist, from the ARC Centre of Excellence for Coral Reef Studies and University of Queensland, has traced the story of the world´s reefs over more than 50 million years and is translating delicate signals from the past to reveal what doomed them in previous...

Color Changes In Coral Reefs Due To Increased Growth
2012-07-10 21:21:09

New research has provided insight into the basic immune response and repair mechanisms of corals to disease and changing environmental conditions. The study, published in the latest issue of the journal Coral Reefs, found that increased growth is the underlying physiological process associated with disease, wounding and stress-related color changes in reef-building corals. The study investigated distinct green fluorescent protein (GFP)-like pigments responsible for the green, red and...

Like their warrior ancestors, leaders of many Pacific Island nations have been making efforts to safeguard their countries, this time by sounding an alarm as the impact of climate change becomes more apparent.  Today their efforts received a big boost with the release of a Scientific Consensus Statement on Climate Change and Coral Reefs that is supported by over 2,600 scientists, showing the threats that reef corals are under across the globe and calling for governments worldwide to take...

Marine scientists at the University of North Carolina at Chapel Hill have linked the decline in growth of Caribbean forereef corals – due to recent warming – to long-term trends in seawater temperature experienced by these corals located on the ocean-side of the reef. The research was conducted on the Mesoamerican Barrier Reef System in southern Belize. The results were revealed online in the July 8 issue of Nature Climate Change, a journal that publishes research on the...

Scientists Use 'Lab-in-a-Box' To Study Coral Reefs
2012-06-08 05:04:39

In what is being called the first controlled ocean acidification experiment ever conducted in shallow coastal waters, an international team of experts has created a miniature laboratory in the Great Barrier Reef in order to simulate anticipated future conditions in the waters of the region's ecosystem. The researchers, including Stanford Woods Institute for the Environment Senior Fellows Jeff Koseff, Rob Dunbar and Steve Monismith, created a so-called "lab-in-a-box" in two to six foot deep...

Jobs, livelihoods and ecotourism industries can benefit from having a diverse supply of weed-eating fish on the world´s coral reefs, marine researchers say. Despite their small size, relative to the sharks, whales, and turtles that often get more attention, herbivorous fish play a vital role in maintaining the health of coral reefs, which support the livelihoods of 500 million people worldwide, say researchers from the ARC Centre of Excellence for Coral Reef Studies at James Cook...

Australia´s sea snakes may be more in danger of extinction than previously thought, marine scientists say. New research on turtleheaded sea snakes that frequent coral reefs in Australia and nearby New Caledonia has found they are strongly attached to their home reef and rarely venture even a few kilometers to neighboring reefs. Researchers from the ARC Centre of Excellence for Coral Reef Studies (CoECRS) and The University of Sydney used genetic ℠fingerprinting´ to show...

Coral Reef
2013-04-20 15:49:21

Coral reefs are submerged structures consisting of calcium carbonate secreted by corals. Coral reefs are colonies of small animals found in marine waters that enclose few nutrients. The majority of coral reefs are constructed from stony corals, which then consist of polyps that come together in groups. The polyps are like small sea anemones, to which they are very closely related. Unlike the sea anemones, coral polyps secrete hard carbonate exoskeletons which provide support and protections...

Chalice Corals, are a family of stony corals in the Pectiniidae family. Members of this family are mostly colonial but at least one species, Echinomorpha nishihirai, is solitary. These corals are endemic to the Indian and Pacific oceans. Pectiniids have a number of different forms but are basically streamlined and smooth. Polyps are large and brightly colored and resemble those of members of the Mussidae family of corals. The polyps are only extended at night. Tentacles are translucent,...

Siderastreidae is a family of colonial, reef building stony corals. Members of this family include symbiotic algae in their tissues which help provide their energy requirements. The World Register of Marine Species lists 7 genera within this family: Anomastraea, Coscinaraea, Craterastrea, Horastrea, Psammocora, Pseudosiderastrea, and Siderastrea. Corals in this family vary in form and include massive, thickly encrusting, columnar, and irregular forms. Corallites are linked by flowing...

Horn corals, known as Rugosa or Tetracoralla, are an extinct order of coral that were abundant during the Middle Ordovician to Late Permian stages. They were known as horn corals because of a unique horn-shaped chamber with a wrinkled (rugose) wall. These mostly solitary corals often reached lengths of nearly 40 inches. However, some species could form large colonies. Rugose corals have a skeleton made up of calcite that is often fossilized. Like modern corals, rugose corals were...

Tabulata is a family of extinct tabulate corals. These corals lived entirely during the Paleozoic era, being found from the Ordovician to the Permian stages. There are about 300 known genera of tabulate corals, of which Aulopora, Favosites, Halysites, Heliolites, Pleurodictyum, Sarcinula and Syringopora are the most common in the fossil record. These corals were mostly found in the shallow waters of the Silurian and Devonian, after which, they became much less common. They became extinct...
