  • Coral skeletons may resist the effects of acidifying oceans
    on August 28, 2017 at 8:41 pm

    Coral skeletons are the building blocks of diverse coral reef ecosystems, which has led to increasing concern over how these key species will cope with warming and acidifying oceans that threaten their stability. New research provides evidence that at least one species of coral build their hard, calcium carbonate skeletons faster, and in bigger pieces, than previously thought. […]

  • Algae fortifies coral reefs in past and present
    on August 28, 2017 at 6:07 pm

    The Great Barrier Reef, and most other large reefs around the world, owe their bulk in large part to a type of red algae that grows on corals and strengthens them. New research has found that ancient coral reefs were also bolstered by their bond with red algae, a finding that could help scientists better understand how reefs will respond to climate change. […]

    on July 20, 2017 at 2:06 pm

    Coral reefs in the Red Sea’s Gulf of Aqaba can resist rising water temperatures, suggests new research. If they survive local pollution, these corals may one day be used to re-seed parts of the world where reefs are dying. The scientists urge governments to protect the Gulf of Aqaba Reefs. […]

  • A super-algae to save our seas? Genetic engineering species to save corals
    on July 20, 2017 at 1:51 pm

    Solutions to climate change, and particularly its effects on the ocean, are needed now more than ever. Coral bleaching caused by climate change is a huge threat to coral reefs. Recent extreme bleaching events have already killed corals worldwide and permanent destruction of reefs is projected within the century if immediate action is not taken. However, genetically engineering a group of microalgae found in corals may enhance their stress tolerance to ocean warming and save coral reefs. […]

  • Oil impairs ability of coral reef fish to find homes and evade predators
    on July 17, 2017 at 3:05 pm

    Just as one too many cocktails can lead a person to make bad choices, a few drops of oil can cause coral reef fish to make poor decisions.
