As global warming whips up more powerful and frequent hurricanes and storms, the world's coral reefs face increased disruption to their ability to breed and recover from damage. That's one of the findings from a new scientific study of the fate of corals in the wake of large climate-driven bleaching and storm events. "We have found clear evidence that coral recruitment "“ the regrowth of young corals "“ drops sharply in the wake of a major bleaching event or a hurricane," says...

Banning or restricting the use of certain types of fishing gear could help the world's coral reefs and their fish populations survive the onslaughts of climate change.An international team of scientists led by Dr Josh Cinner of the ARC Centre of Excellence for Coral Reef Studies at James Cook University has proposed that bans on fishing gear - like spear guns, fish traps, beach seine nets, and gill nets "“ could aid in the recovery of reefs and fish populations hard hit by coral...

A recent study shows that a change in climate has assisted in advancing the leveling of the complex, multi-layered construct of Caribbean coral reefs. This jeopardizes their ability to provide a buffer against tropical storms and be a nursery for fish stocks. The analysis of 500 surveys of 200 reefs, conducted between 1969 and 2008, revealed that the most complex types of coral reef had been virtually destroyed throughout the entire Caribbean. These reefs, which are characterized by table...

Disruptions causing decline of coral reefs around the world Corals, it appears, have a genetic complexity that rivals that of humans, have sophisticated systems of biological communication that are being stressed by global change, and are only able to survive based on proper function of an intricate symbiotic relationship with algae that live within their bodies, say researchers in a paper published in this week's issue of the journal Science. Disruptions in these biological and communication...

NUI Galway researchers, during a recent deep-water expedition, have confirmed the existence of a major new coral reef province on the southern end of the Porcupine Bank off the west coast of Ireland. The province covers an area of some 200 sq.km and contains in the order of 40 coral reef covered carbonate mounds. These underwater hills rise as high as 100m above the seafloor. The deep-water research expedition took place earlier this month aboard the Marine Institute research vessel, the RV...

Better coral reef assessment and management are needed if the reefs are to survive global warming, a conservation group said Wednesday in Washington. The International Union for Conservation of Nature and Natural Resources made the statement in releasing a report Resilience Assessment of Coral Reefs. We already know that climate change is destroying coral reefs through warming waters that cause coral bleaching and through acidifying oceans that hinders coral skeleton growth, Garriel...

Experts say that more than half of the world's coral reefs could disappear in the next 50 years, in large part because of higher ocean temperatures caused by climate change. But now Stanford University scientists have found evidence that some coral reefs are adapting and may actually survive global warming. "Corals are certainly threatened by environmental change, but this research has really sparked the notion that corals may be tougher than we thought," said Stephen Palumbi, a professor of...

A nearly complete collection of genes for a species of reef-building coral has been assembled by a team led by biologists from The University of Texas at Austin. The scientists will use the genetic data to understand natural variations in corals from around the world and how they respond, at the genetic level, to rising water temperatures. "One of the most important questions for coral biologists is whether it will be possible for corals to adapt to the warming oceans," says Eli Meyer,...

A new study appearing in Restoration Ecology describes a novel technique for reattaching large sponges that have been dislodged from coral reefs. The findings could be generally applied to the restoration of other large sponge species removed by human activities or storm events. 20 specimens of the Caribbean giant barrel sponge were removed and reattached at Conch Reef off of Key Largo, Florida in 2004 and 2005 at depths of 15m and 30m. The sponges were affixed to the reef using sponge...

Children of baby boomers aren't the only ones who have taken to setting up home far from where their parents live. A new study published this week in the Proceedings of the National Academy of Sciences documents how larval dispersal connects marine fish populations in a network of marine protected areas "“ information that is critical for fisheries managers. "What this study does for the first time is to demonstrate that a percentage of larvae spawned on one marine reserve actually make...

Knotted Fan Coral, (Melithaea ochracea), is a species of colonial soft coral that is found in tree-like fans on shallow reefs in the South China Sea between Taiwan and Indonesia, including Singapore and Malaysia. In Taiwan, it is the most widespread coral in its family Gorgonacea. It is found on the higher parts of reef fronts where its numerous small polyps can feed at water flow rates varying from 1.6 to 16 inches per second. This species usually grow to about 8 inches in length, with...

Octopus Coral, (Galaxea fascicularis), also known as Fluorescence Grass Coral, Galaxy Coral. Star Coral, Crystal Coral, Brittle Coral and Starburst Coral, is a species of colonial stony coral commonly found on reef slopes in the Indian and Pacific ocean regions, as well as the Red Sea and the Gulf of Aden. It is most commonly found where wave action is weak, usually at a depth of 79 inches to 49 feet below sea level. It is a common coral species among reef aquarium enthusiasts. This coral...

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...

Leaf Plate Montipora, (Montipora capricornis), also known as Vase Coral, Cap Coral, or simply Montipora, is a species of stony coral found in the Indian and Pacific oceans. It is also found in reefs in the Red Sea. It usually inhabits the top half of the reef where photosynthesis can occur. It branches out from the foundation into an area with adequate sunlight. This species forms flat, plating colonies. The colonies expand by adding to their foundations and further spreading out....

  • In music, a work for a keyboard-instrument, like the pianoforte or organ, originally intended to utilize and display varieties of touch: but the term has been extended so as to include many irregular works, similar to the prelude, the fantasia, and the improvisation.
This word is Italian in origin, coming from the feminine past participle of 'toccare,' to touch.
