Abundant, Dominant Corals Still Face Threat Of Extinction
2013-11-16 06:48:46

April Flowers for redOrbit.com - Your Universe Online Scientists generally assume that corals do not face a risk of extinction unless they become very rare, or their range is restricted. A new study, published in the journal Bioscience, reveals that global changes in climate and ocean chemistry affect corals whether scarce or abundant, and often it is the dominant, abundant corals with wide distributions that are affected the most. A research team, led by Charles Birkeland from the...

Manmade Activities Behind Caribbean Coral Die-Off
2013-02-15 10:42:20

April Flowers for redOrbit.com - Your Universe Online A new study, led by the University of Georgia, solves the mystery of the dying Caribbean coral. Plunk down a wastewater treatment plant anywhere along a Caribbean coast and watch the coral reefs nearby start dying, by a means unknown to science. "You'd have all the makings of a great mystery novel," says ecologist James Porter of the University of Georgia. Unlike a novel, however, this story is true. "Between 1996 and 2012,...

Spawning Of Threatened Pillar Coral Observed For First Time In Florida Reef System
2012-08-09 11:25:00

Lawrence LeBlond for redOrbit.com - Your Universe Online Male and female threatened pillar coral have been documented for the first time spawning together in the Florida Keys National Marine Sanctuary, said researchers with the Florida Fish and Wildlife Conservation Commission. The researchers were exhilarated by the displays of male and female pillar coral releasing their reproductive cells during a spawning session in the Upper Keys on Saturday, just after the full moon. At precisely...

Recent experiments conducted at the Australian Institute of Marine Science (AIMS) produced striking results, showing for the first time that corals hosting a single type of “zooxanthellae” can have different levels of thermal tolerance — a feature that was only known previously for corals with a mix of zooxanthellae. Zooxanthellae are algal cells that live within the tissue of living coral and provide the coral host with energy; the relationship is crucial for the...

Corals Can Sense What's Coming

Australian scientists have thrown new light on the mechanism behind the mass death of corals worldwide as the Earth´s climate warms. Coral bleaching, one of the most devastating events affecting coral reefs around the planet, is triggered by rising water temperatures. It occurs when the corals and their symbiotic algae become heat-stressed, and the algae which feed the corals either die or are expelled by the coral. There have been seven major bleaching events globally in the past...

  Vital clues to coral reef recovery have been identified in a remarkable research project in which three scientists labored to hand-build 30 coral reefs from hundreds of tons of rock and gravel. Working in a shallow, sandy area of Kimbe Bay, Papua New Guinea, the team constructed their artificial reefs over several weeks, with just a boat and their bare hands, to find out whether it is possible to rescue a damaged coral reef from obliteration and restore its richness....

US researchers said on Wednesday that human sewage is causing a disease that is killing elkhorn coral. This coral was listed as endangered several years ago due to a massive die off.  The coral lives in waters off south Florida and the Bahamas and was once the most prevalent in the Caribbean but has been vanishing due to white pox disease, caused by the bacterium Serratia marcescens that is found in human and animal waste. Researchers analyzed bacteria from a wastewater treatment...

Univ. of Miami scientists illustrate threat of increased carbon dioxide to coral reproduction A new study led by scientists at the University of Miami Rosenstiel School of Marine and Atmospheric Science suggests that over the next century recruitment of new corals could drop by 73 percent, as rising CO2 levels turn the oceans more acidic. The research findings reveal a new danger to the already threatened Caribbean and Florida reef Elkhorn corals. "Ocean acidification is widely viewed as an...

An Australian scientist has discovered what could be the world's rarest coral in the remote North Pacific Ocean. The unique Pacific elkhorn coral was found while conducting underwater surveys of Arno atoll in the Marshall Islands, by coral researcher Dr Zoe Richards of the ARC Centre of Excellence for Coral Reef Studies (CoECRS). The coral bears a close physical resemblance to the critically endangered and fast-vanishing elkhorn coral (Acropora palmata) of the Atlantic Ocean, but genetic...

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...
