  • Study highlights formation of beachrock in resisting climate-induced sea level rises
    on May 31, 2017 at 2:26 pm

  • Rethinking role of viruses in coral reef ecosystems
    on May 23, 2017 at 12:20 pm

    Viruses are thought to frequently kill their host bacteria, especially at high microbial density. A state called lysogeny, in which viruses lie dormant but don't kill their hosts, has been thought to be relatively rare , mostly occurring at low bacterial concentrations. A new study suggests lysogeny might be much more common than previously believed. These findings could lead to a better understanding of degraded coral reef ecosystems and how to preserve them. […]

  • New coral bleaching database to help predict fate of global reefs
    on May 1, 2017 at 6:16 pm

  • Coral reefs struggle to keep up with rising seas, leave coastal communities at risk
    on April 20, 2017 at 1:37 pm

    In the first ecosystem-wide study of changing sea depths at five large coral reef tracts in Florida, the Caribbean and Hawai'i, researchers found the sea floor is eroding in all five places, and the reefs cannot keep pace with sea level rise. As a result, coastal communities protected by the reefs are facing increased risks from storms, waves and erosion. […]

  • Fish social lives may be key to saving coral reefs
    on April 10, 2017 at 7:48 pm

    Fish provide a critical service for coral reefs by eating algae that can kill coral and dominate reefs if left unchecked. A new study, which analyzed the social feeding behavior of reef fish, suggests that overfishing not only removes vital algae-eaters, but it may cause remaining fish to eat less. […]

  • Powers of attraction could decimate deadly starfish
    on April 5, 2017 at 5:10 pm

    Scientists studying the Great Barrier Reef have made a breakthrough discovery that could protect one of the Seven Natural Wonders. Biologists believe they can use the powers of attraction to decimate one of the reef's fiercest enemies. […]

  • 'Spiderman' worm-snails discovered on Florida shipwreck
    on April 5, 2017 at 12:40 pm

    Scientists have discovered a new species of worm-snail on a shipwreck in the Florida Keys. The new species, which is colorful and shoots mucus webs to trap food, is likely an invasive species from the Indo-Pacific and could have important coral reef conservation implications. […]

  • Corals die as global warming collides with local weather in the South China Sea
    on March 23, 2017 at 2:58 pm

    In the South China Sea, a 2°C rise in the sea surface temperature in June 2015 was amplified to produce a 6°C rise on Dongsha Atoll, a shallow coral reef ecosystem, killing approximately 40 percent of the resident coral community within weeks, according to a study. […]

  • Dead zones may threaten coral reefs worldwide
    on March 21, 2017 at 4:25 pm

    Dead zones affect dozens of coral reefs around the world and threaten hundreds more according to a new study. Watching a massive coral reef die-off on the Caribbean coast of Panama, they suspected it was caused by a dead zone -- a low-oxygen area that snuffs out marine life -- rather than by ocean warming or acidification. […]

  • Scientists mobilize as bleaching resumes on Great Barrier Reef
    on March 15, 2017 at 6:38 pm

    Coral researchers are remobilizing to conduct aerial and underwater surveys along the Great Barrier Reef and elsewhere in Australia as coral bleaching reappears for the second year in a row. The decision coincides with the release today of a study in the journal Nature warning the Reef's resilience is rapidly waning. […]

  • Biologists identify ancient stress response in corals
    on March 8, 2017 at 7:53 pm

  • Underwater seagrass beds dial back polluted seawater
    on February 16, 2017 at 7:39 pm

  • Deep reefs unlikely to save shallow coral reefs
    on February 15, 2017 at 7:59 pm

    Often highlighted as important ecological refuges, deep sections of coral reefs (30-60 m depth) can offer protection from the full force of climate change-related impacts, such as intensifying storms and warm-water bleaching. However new research questions their role in acting as a source of new corals for damaged shallow reefs. […]
