Coral Algae Overgrowth Endangers Whole Ecosystems
2012-09-20 11:55:50

April Flowers for redOrbit.com - Your Universe Online Overfishing and nitrate pollution can destroy coral reefs by allowing an overgrowth of algae that brings with it unwanted pathogens, chokes off oxygen and disrupts helpful bacteria. These are the findings of a new study out of the Oregon State University, published recently in PLoS One. Large algal species, or "macroalgae," are big enough to essentially smother corals. These macralgae grow at accelerated rates when sewage waste...

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...

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...

Marine Protected Areas Benefit Fisheries

redOrbit Staff & Wire Reports - Your Universe Online The first clear evidence that no-take protected areas can help restock exploited fish populations on neighboring reefs was presented at the International Coral Reef Symposium today. These answers will help resolve a long-running discussion worldwide about whether areas blocked off to all forms of fishing help replenish fish numbers outside the marine protected areas (MPAs). “Using DNA fingerprinting technology, we now can...

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...

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...

Climate Change Affected Coral Reefs In Ancient Times
2012-07-06 12:20:36

Brett Smith for redOrbit.com - Your Universe Online Climate change has historically affected the growth of coral reefs, with some reefs experiencing a long-term growth stoppage around 4,000 years ago, according to newly published research in the journal Science. An international team of scientists, who used radiocarbon dating and other research techniques, said that the growth stoppage they identified in eastern Pacific reefs took 2,500 years to recover from. "We were shocked to find...

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...
