  • How urban seasnakes lost their stripes
    on August 10, 2017 at 4:04 pm

    Researchers studying turtle-headed seasnakes living on coral reefs in the Indo-Pacific noticed something unusual about the snakes' color patterns: seasnakes living in more pristine parts of the reef were decorated with black-and-white bands or blotches. Those in places with more human activity -- near the city or military activity -- were black. Those color differences are explained by differences in the snakes' exposure to pollution. […]

  • 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. Oil impacts the higher-order thinking of coral reef fish in a way that could prove dangerous for them -- and for the coral reefs where they make their home. […]

  • 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. […]
