  • Beluga whales have sensitive hearing, little age-related loss
    on June 20, 2018 at 2:06 pm

    Scientists published the first hearing tests on a wild population of healthy marine mammals. The tests on beluga whales in Bristol Bay, Alaska, revealed that the whales have sensitive hearing abilities and the number of animals that experienced extensive hearing losses was far less than what scientists had anticipated. […]

  • World's first known manta ray nursery
    on June 19, 2018 at 4:31 pm

    Located in the Gulf of Mexico off the coast of Texas at NOAA's Flower Garden Banks National Marine Sanctuary, the juvenile manta ray habitat is the first of its kind to be described in a scientific study. […]

  • Deep-sea marine sponges may hold key to antibiotic drug resistance
    on June 19, 2018 at 4:30 pm

    FAU's Harbor Branch houses more than 1,000 strains of actinobacteria, one of the most prolific microbial groups for the production of natural products. Derived from sea sponges and other macro-organisms, several strains were identified for their potent antifungal activity, for anti-MRSA activity, and for both antifungal and antibacterial activities. A key finding was the identification of a strain that produced metabolites that are more potent than the bacterial antibiotic, vancomycin, against C. difficile. […]

  • Coral reef 'oases' offer glimmer of hope
    on June 19, 2018 at 2:24 am

    Scientists have discovered small communities of corals that are flourishing against the odds while so many around the world are dying. […]

  • Local interventions boost coral's resilience to bleaching
    on June 19, 2018 at 2:24 am

    Local conservation actions can significantly boost coral's resilience to, and recovery from, climate-induced thermal bleaching by reducing other energy-sapping stresses the coral faces, a new study finds. Scientists found they could reduce the extent of bleaching by half if they removed or reduced populations of coral-eating snails from affected reefs. The coral's recovery from bleaching was also enhanced. […]

  • Rising sea temperatures threaten survival of juvenile albatross
    on June 18, 2018 at 2:26 pm

    Changes in sea surface temperature affect the survival of albatross during their first year at sea, resulting in a reduced population growth rate when temperatures are warmer than the current average, a new study has revealed. […]

  • Great white sharks dive deep into warm-water whirlpools in the Atlantic
    on June 18, 2018 at 2:25 pm

    Tracking data from two great white sharks reveals that they spend more time deep inside warm-water eddies, suggesting that's where they like to feed. […]

  • Key ocean fish can prevail with changes to farmed fish, livestock diets
    on June 15, 2018 at 1:38 am

    A new study shows that if current aquaculture and agriculture practices remain unchanged into the future, wild forage fish populations likely will be overextended by the year 2050, and possibly sooner. However, making sensible changes in aquaculture and agriculture production would avoid reaching that threshold. […]

  • Climate change has fish moving faster than regulations can keep up
    on June 15, 2018 at 1:37 am

    The world's system for allocating fish stocks is being outpaced by the movement of fish species in response to climate change, according to a study undertaken by an international team of marine ecologists, fisheries and social scientists, and lawyers. […]

  • Stress test to predict how diatoms will react to ocean acidification
    on June 13, 2018 at 8:26 pm

    Researchers have shown that diatoms can withstand population collapse in an acidified environment by conserving valuable energy normally used for carbon dioxide consumption. […]

  • Attacking bacteria with shark skin-inspired surfaces
    on June 13, 2018 at 3:37 pm

    Sharks are often the subject of TV specials or news stories focusing on their attacks on humans. But scientists are finding that sharks could inspire a new type of surface that would attack bacteria, helping humans instead of hurting them. Researchers have designed a coating that is infused with antimicrobial agents and has the patterned diamond-like texture of shark skin. […]

  • Large-scale whaling in north Scandinavia may date back to 6th century
    on June 13, 2018 at 3:37 pm

    The intensive whaling that has pushed many species to the brink of extinction today may be several centuries older than previously assumed. […]

  • Sea urchins see with their feet
    on June 12, 2018 at 2:57 pm

    Sea urchins lack eyes, but can see with their tentacle-like tube feet instead, previous research has indicated. Now, researchers have tested their vision in a new study, and shown that while sea urchins have fairly low resolution vision -- it is good enough to fulfill their basic needs. […]

  • Putting animals in their best light: Some shades of LED lamps threaten wildlife
    on June 12, 2018 at 1:06 pm

    A research team identifies harmful effects to wildlife as LED lights proliferate. Some hues, including blues and whites, imperil creatures while other wavelengths are more benign. They devised an interactive web-based tool to help people make wildlife-friendly choices in outdoor lighting. […]

  • Volcanic activity, declining ocean oxygen triggered mass extinction of ancient organisms
    on June 11, 2018 at 8:05 pm

    Global climate change, fueled by skyrocketing levels of atmospheric carbon dioxide, is siphoning oxygen from today's oceans at an alarming pace -- so fast that scientists aren't entirely sure how the planet will respond. […]

  • Fueling a deep-sea ecosystem
    on June 11, 2018 at 7:27 pm

    Miles beneath the ocean's surface in the dark abyss, vast communities of subseafloor microbes at deep-sea hot springs are converting chemicals into energy that allows deep-sea life to survive -- and even thrive -- in a world without sunlight. Until now, however, measuring the productivity of subseafloor microbe communities -- or how fast they oxidize chemicals and the amount of carbon they produce -- has been nearly impossible. […]

  • Proactive conservation management strategy urged for North Atlantic right whale
    on June 11, 2018 at 6:41 pm

    Marine ecologists urge a more proactive conservation management strategy for the North Atlantic right whale. […]

  • Large-scale study indicates novel, abundant nitrogen-fixing microbes in surface ocean
    on June 11, 2018 at 5:34 pm

    A large-scale study of the Earth's surface ocean indicates the microbes responsible for fixing nitrogen there -- previously thought to be almost exclusively photosynthetic cyanobacteria -- include an abundant and widely distributed suite of non-photosynthetic bacterial populations. […]

  • Secret to whale shark hotspots
    on June 8, 2018 at 2:33 pm

    A study has uncovered the secret to why endangered whale sharks gather on mass at just a handful of locations around the world. […]

  • Secrets of fish population changes revealed
    on June 8, 2018 at 2:19 pm

    Populations of fish in the ocean are notoriously variable, waxing and waning in often unpredictable ways. Knowing what drives changes in fish population sizes is important for managing fisheries and conserving species. For the first time, scientists have linked the ecology of adult fish populations inhabiting coral reefs with the dispersal of baby fish between reefs, reporting the dynamics of a living network called a 'marine metapopulation.' […]
