European Settlement Caused Collapse Of Great Barrier Reef Coral
2012-11-07 10:07:33

Lawrence LeBlond for redOrbit.com - Your Universe Online Australia´s Great Barrier Reef, the largest coral system in the world, so big that it can be seen from space, is one of the planet´s most remarkable natural wonders. But researchers from University of Queensland have now revealed this precious ecosystem is not faring so well. The problem: European settlement and extensive degradation on mainland Australia. The expansion of European settlement in Australia has been...

Sweden’s Säcken Reef Facing Death
2012-10-23 21:13:37

Alan McStravick for redOrbit.com — Your Universe Online The Säcken reef in the Koster Fjord in Sweden is that country´s last remaining cold-water coral reef and it is under a distinct threat of extinction. Like the more common warm-water reefs, cold-water reefs are known for their rich biological diversity. With the Säcken reef in distress, researchers from the University of Gothenburg have started a restoration project extracting healthy corals...

Coastal habitats provide cost effective solutions for hazard mitigation and coral reefs may provide risk reduction benefits to 200 million people around the world Arlington, VA (PRWEB) October 11, 2012 Today in Brussels, Belgium, the German Alliance for Development Works (Alliance), United Nations University Institute for Environment and Human Security (UNU-EHS) and The Nature Conservancy presented the World Risk Report 2012, which shows how environmental degradation reduces the capacity of...

Coral Hotspots Found In Deepwater Canyons
2012-09-28 04:33:26

Alan McStravick for redOrbit.com - Your Universe Online When most people think of coral reefs, they are transported to temperate waters in a tropical locale. To even locate a coral ecosystem in the cold waters of the mid and north Atlantic would be a difficult endeavor. Or, at least, one would have thought. A recent exploration of the continental shelf and slope of the Northeastern United States has revealed coral hotspots. These are areas that have an abundance of sea life existing in...

New Model Used To Find Where Corals Are Most Likely To Survive Climate Change
2012-08-31 11:51:43

Marine conservationists from the Wildlife Conservation Society working with other coral reef experts have identified heat-tolerant coral species living in locations with continuous background temperature variability as those having the best chance of surviving climate change, according to a new simplified method for measuring coral reef resilience. Therefore, coral reefs with these characteristics should receive immediate attention for conserving this highly threatened ecosystem, according...

Atlantic Ocean Gets Hit With Invasive Brittle Star Species
2012-08-20 12:37:24

redOrbit Staff & Wire Reports - Your Universe Online The appearance and ecology of Atlantic coral reef habitats could be altered by yellow brittle star A study co-written by Dr. Gordon Hendler of the Natural History Museum of Los Angeles County (NHM) about an invasive species of brittle star, Ophiothela mirabilis, has been published online in Coral Reefs, the Journal of the International Society for Reef Studies. Growing populations have established themselves at distant points in...

Additions To Coral Reef Woes Are Microbes, Sponges And Worms
2012-08-07 13:46:12

Study by Wildlife Conservation Society and University of the Azores identifies additional risks to reefs stemming from pollution and heavy fishing Microbes, sponges, and worms–the side effects of pollution and heavy fishing–are adding insult to injury in Kenya's imperiled reef systems, according to a recent study by the Wildlife Conservation Society and the University of Azores. The authors of the study have found that pollution and overfishing on reef systems have an...

Thriving Coral Reef In Muddy Waters
2012-08-04 13:43:39

redOrbit Staff & Wire Reports - Your Universe Online The Middle Reef, part of Australia´s Great Barrier Reef, is growing more quickly than reefs in other areas with lower levels of sediment stress, a new study has found. Rapid coral reef growth has been identified in environments with large amounts of sediment, conditions previously thought to be detrimental to reef growth. The study, led by the University of Exeter with an international team of scientists, is published today...

Coral Reef

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...
