Coral reef fishes prove invaluable in the study of evolutionary ecology
ScienceDaily: Coral Reef News - Thu, 05/16/2013 - 11:36
Coral reef fish species have proven invaluable for experimental testing of key concepts in social evolution and already have yielded insights about the ultimate reasons for female reproductive suppression, group living, and bidirectional sex change.

Cooling ocean temperature could buy more time for coral reefs
ScienceDaily: Coral Reef News - Tue, 05/14/2013 - 10:28
Limiting the amount of warming experienced by the world's oceans in the future could buy some time for tropical coral reefs, say researchers.

Microbes capture, store, and release nitrogen to feed reef-building coral
ScienceDaily: Coral Reef News - Tue, 05/14/2013 - 07:54
Microscopic algae that live within reef-forming corals scoop up available nitrogen, store the excess in crystal form, and slowly feed it to the coral as needed, according to a study published in mBio.

Corals turn to algae for stored food when times get tough
ScienceDaily: Coral Reef News - Tue, 05/14/2013 - 07:54
Researchers present new evidence for the crucial role of algae in the survival of their coral hosts. Ultra-high resolution images reveal that the algae temporarily store nutrients as crystals, building up reserves for when supplies run low.

Coral reefs suffering, but collapse not inevitable
ScienceDaily: Coral Reef News - Thu, 05/09/2013 - 11:34
Coral reefs are in decline, but their collapse can still be avoided with local and global action. That's according to findings based on an analysis that combines the latest science on reef dynamics with the latest climate models.

Insights into deadly coral bleaching could help preserve reefs: Surprising result from study of 1893 World's Fair corals
ScienceDaily: Coral Reef News - Tue, 04/23/2013 - 12:51
Coral reefs are stressed because of climate change. Researchers have discovered corals themselves play a role in their susceptibility to deadly coral bleaching due to the light-scattering properties of their skeletons. No one else has shown this before. Using optical technology designed for early cancer detection, the researchers discovered that reef-building corals scatter light in different ways to the symbiotic algae that feed the corals.

Human shadow cast over the Caribbean slows coral growth
ScienceDaily: Coral Reef News - Tue, 04/09/2013 - 10:16
Striking Caribbean sunsets occur when particles in the air scatter incoming sunlight. But a particulate shadow over the sea may have effects underwater. A research team has linked airborne particles caused by volcanic activity and air pollution to episodes of slow coral-reef growth.

Air pollution stunts coral growth
ScienceDaily: Coral Reef News - Sun, 04/07/2013 - 12:32
A new study has found that pollution from fine particles in the air -- mainly the result of burning coal or volcanic eruptions -- can shade corals from sunlight and cool the surrounding water resulting in reduced growth rates.

Remote coral reefs can be tougher than they look: Western Australia’s Scott Reef has recovered from mass bleaching
ScienceDaily: Coral Reef News - Fri, 04/05/2013 - 08:45
Isolated coral reefs can recover from catastrophic damage as effectively as those with nearby undisturbed neighbors, a long-term study by marine biologists has shown. Scott Reef, a remote coral system in the Indian Ocean, has largely recovered from a catastrophic mass bleaching event in 1998, according to the study.

Hope for Galapagos wildlife threatened by marine invaders
ScienceDaily: Coral Reef News - Tue, 03/26/2013 - 10:20
Increasing tourism and the spread of marine invasive non-native species is threatening the unique plant and marine life around the Galapagos Islands.

Innovative Study Examines Whether Marine-Protected Areas Can Save Fishermen as Well as Fish (preview)
Scientific American Topic - Coral Reefs - Tue, 03/26/2013 - 08:00
On a brisk August night Dortheus Mentansan slipped into the calm ocean in a wood outrigger canoe with a lantern tied to the bow. A slight, solemn man with the precise paddle stroke that comes from 30 years of practice, Dortheus counts himself as a descendant of the original clan that settled here in the Mayalibit Bay region of Indonesia's remote Raja Ampat islands. Clouds blocked the moon, but Dortheus had no trouble navigating.

Fluorescent light revealed as gauge of coral health: Mysterious glow of light found to correlate with coral stress prior to bleaching
ScienceDaily: Coral Reef News - Tue, 03/12/2013 - 08:29
Coral reef decline in recent years due to a variety of threats -- from pollution to climate warming -- has lent urgency to the search for new ways to evaluate their health. A new study has revealed that fluorescence, the dazzling but poorly understood light produced by corals, can be an effective tool for gauging their health.

5 Shark Species May Gain Protection Boost from New Findings
Scientific American Topic - Coral Reefs - Wed, 03/06/2013 - 10:00
As 177 nations gather in Bangkok this week to deliberate trade restrictions on potentially endangered animals, new research reveals how important these deliberations are to the long-term survival of five species of sharks.

New maps depict potential worldwide coral bleaching by 2056
ScienceDaily: Coral Reef News - Mon, 02/25/2013 - 12:20
New maps by scientists show how rising sea temperatures are likely to affect all coral reefs in the form of annual coral bleaching events under different emission scenarios. If carbon emissions stay on the current path most of the world's coral reefs (74 percent) are projected to experience coral bleaching conditions annually by 2045, results of the study show.

Conserving corals by understanding their genes
ScienceDaily: Coral Reef News - Thu, 02/21/2013 - 19:40
In reef-building corals variations within genes involved in immunity and response to stress correlate to water temperature and clarity, finds a new study. This information could be used to conserve or rebuild reefs in areas affected by climate change, by changes in extreme weather patterns, increasing sedimentation or altered land use.

Picky eater fish clean up seaweeds from coral reefs
ScienceDaily: Coral Reef News - Tue, 02/12/2013 - 15:44
Using underwater video cameras to record fish feeding on South Pacific coral reefs, scientists have found that herbivorous fish can be picky eaters – a trait that could spell trouble for endangered reef systems.

How new corals species form in the ocean
ScienceDaily: Coral Reef News - Wed, 02/06/2013 - 16:23
Biological sciences professors have investigated how corals specialize to particular environments in the ocean. They propose that the large dispersal potential of coral larvae in open water and the proximity of different species on the ocean floor creates a mystery for researchers who study speciation, asking, "How can new marine species emerge without obvious geographic isolation?"
