  • Rising temperatures turning major sea turtle population female
    on January 11, 2018 at 3:14 pm

    Scientists have used a new research approach to show that warming temperatures are turning one of the world's largest sea turtle colonies almost entirely female, running the risk that the colony cannot sustain itself in coming decades, newly published research concludes. […]

  • The window for saving the world's coral reefs is rapidly closing
    on January 4, 2018 at 8:35 pm

    For the first time, an international team of researchers has measured the escalating rate of coral bleaching at locations throughout the tropics over the past four decades. The study documents a dramatic shortening of the gap between pairs of bleaching events, threatening the future existence of these iconic ecosystems and the livelihoods of many millions of people. […]

  • The Caribbean is stressed out
    on December 28, 2017 at 10:06 pm

    Forty percent of the world's 7.6 billion people live in coastal cities and towns. A team of marine biologists just released 25 years of data about the health of Caribbean coasts. The study provides new insights into the influence of both local and global stressors in the basin, and some hope that the observed changes can be reversed by local environmental management. […]

  • Conserving coral communities
    on December 27, 2017 at 7:59 pm

    For years, people have sought to stop the loss of coral reefs by transplanting corals grown in underwater 'nurseries' to damaged reefs, but little work had been done to evaluate how effective such efforts were. A new study, however, suggests those projects have a positive impact on local fish populations, both in the short term and over time. […]

  • Resilience of Great Barrier Reef offers opportunities for regeneration
    on November 29, 2017 at 4:04 am

    New research has found that, despite the extensive damage to coral in recent events, there are still 100 reefs on the Great Barrier Reef that are well suited to promoting the regional recovery of the ecosystem after major disturbances. […]

  • Fear of sharks influences seaweed growth on Fijian coral reefs
    on November 27, 2017 at 6:58 pm

    Fishes' fear of sharks helps shape shallow reef habitats in the Pacific, according to new research. The study is the first clear case of sharks altering a coral reef ecosystem through an indirect effect - creating an atmosphere of fear that shifts where herbivores feed and seaweeds grow. […]

  • Study urges global-change researchers to embrace variability
    on November 15, 2017 at 8:36 pm

    A new review article presents evidence that argues for a more nuanced approach to the design of global-change experiments -- one that acknowledges and purposefully incorporates the variability inherent in nature. […]

  • Photomosaic technology finds order in chaos of coral reefs
    on November 15, 2017 at 3:49 pm

    Scientists have created and analyzed detailed photomosaics of the coral reef at Palmyra Atoll using advanced imaging and digitization technology. […]

  • Tipping point for oyster restoration
    on November 13, 2017 at 7:42 pm

    Study shows that reefs built to reach a foot or more above the bottom develop into healthy, self-sustaining ecosystems, while those rebuilt at lower heights are quickly buried by sediment. […]

  • Great Barrier Reef protected zones help fish in even lightly exploited areas
    on November 8, 2017 at 7:37 pm

    Protected zones of the Great Barrier Reef benefit fish even at the relatively lightly-fished northern reefs, according to a new study. […]

  • Seagrass biodiversity is both a goal and a means for restoration
    on November 8, 2017 at 6:18 pm

    Planting multiple seagrass species, rather than a single species, could be better for restoring damaged coastal ecosystems in Indonesia's Coral Triangle. […]

  • Impact of coral bleaching on Western Australia's coastline
    on November 8, 2017 at 3:22 pm

    The 2016 mass bleaching event on Western Australia's coastline is the most severe global bleaching event to ever be recorded. New research records the impact of this event to the rugged reefs of Western Australia. […]

  • Can corals adapt to climate change?
    on November 1, 2017 at 6:17 pm

    Cool-water corals can adapt to a slightly warmer ocean, but only if global greenhouse gas emissions are reduced, a study has found. Some corals in the normally cool waters of the Cook Islands carry genetic variants that predispose them to heat tolerance. This could help the population adapt more quickly to rising temperatures. But they may not adapt quickly enough to outpace climate change. […]

  • Life goes on for marine ecosystems after cataclysmic mass extinction
    on October 20, 2017 at 1:22 pm

    One of the largest global mass extinctions did not fundamentally change marine ecosystems, scientists have found. […]

  • Maintaining fish biomass the key to conserving reef fish biodiversity
    on October 19, 2017 at 2:10 pm

    A new study has found that conserving fish diversity in Madagascar's coral reef systems may depend on maintaining fish biomass above critical levels. […]

  • Fossil coral reefs show sea level rose in bursts during last warming
    on October 19, 2017 at 2:09 pm

    Scientists have discovered that Earth's sea level did not rise steadily when the planet's glaciers last melted during a period of global warming; rather, sea level rose sharply in punctuated bursts. […]

  • Worldwide change in shallow reef ecosystems predicted as waters warm
    on October 18, 2017 at 7:18 pm

    A new study based on the first global survey of marine life by scuba divers has provided fresh insights into how climate change is affecting the distribution of marine life. The research predicts that as the oceans warm fish -- which appear to be superior predators in warm water -- will extend their ranges away from the equator and cause a decline in the diversity of invertebrates such as crabs, lobsters, sea urchins and whelks. […]

  • Hardy corals make their moves to build new reefs from scratch
    on October 18, 2017 at 3:35 pm
