Study Shows Adaptive Capacity Of Reef Corals To Climate Change May Be Widespread
2012-04-12 07:42:53

Global survey of corals using high sensitivity genetic analysis shows many species can host multiple symbionts. A new study by scientists at the University of Miami's Rosenstiel School of Marine & Atmospheric Science suggests that many species of reef-building corals may be able to adapt to warming waters by relying on their closest aquatic partners - algae. The corals' ability to host a variety of algal types, each with different sensitivities to environmental stress, could offer a...

Corals may be better placed to cope with the gradual acidification of the world´s oceans than previously thought — giving rise to hopes that coral reefs might escape climatic devastation. In new research published in the journal Nature Climate Change, an international scientific team has identified a powerful internal mechanism that could enable some corals and their symbiotic algae to counter the adverse impact of a more acidic ocean. As humans release ever-larger amounts of...

Novel excavation technique attributes prior damage to land clearing and overfishing The decline of Caribbean coral reefs has been linked to the recent effects of human-induced climate change. However, new research led by scientists at Scripps Institution of Oceanography at UC San Diego suggests an even earlier cause. The bad news — humans are still to blame. The good news — relatively simple policy changes can hinder further coral reef decline. Employing a novel excavation...

Anoxia and toxic sulfide are a menace to coral tissue Researchers of the Max Planck Institute for Marine Microbiology along with Australian colleagues, have examined corals from the Great Barrier Reef affected by the Black Band Disease and identified the critical parameters that allow this prevalent disease to cause wide mortality of corals around the world. Corals infected with Black Band show a characteristic appearance of healthy tissue displaced by a dark front, the so called Black...

Special conservation zones known as marine protected areas provide many direct benefits to fisheries and coral reefs. However, such zones appear to offer limited help to corals in their battle against global warming, according to a new study. To protect coral reefs from climate change, marine protected areas need to be complemented with policies that can meaningfully reduce greenhouse gas emissions, researchers said. The new study was conducted by scientists from Conservation...

Loss of predatory fish leads to more sea urchins, less coralline algae, and lower recruitment of juvenile corals on Kenyan reefs A study of the tropical coral reef system along the coastline of Kenya has found dramatic effects of overfishing that could threaten the long-term health of the reefs. Led by scientists at the University of California, Santa Cruz, the study was published in the journal Coral Reefs (online publication January 28). The researchers found that the loss of...

More than 300 eminent scientists from 21 other countries around the world today urged the Australian Federal Government to create the world´s largest no-take marine reserve in the Coral Sea. “Marine reserves are an important tool for managing and restoring ecosystems. They protect brood stocks for sustainable fisheries and rebuild distorted foodwebs. We know how well they work because of the differences that we observe again and again between different marine zones under...

Over dinner on R.V. Calypso while anchored on the lee side of Glover´s Reef in Belize, Jacques Cousteau told Phil Dustan that he suspected humans were having a negative impact on coral reefs. Dustan–a young ocean ecologist who had worked in the lush coral reefs of the Caribbean and Sinai Peninsula–found this difficult to believe. It was December 1974. But Cousteau was right. During the following three-plus decades, Dustan, an ocean ecologist and biology professor at the...

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...
