  • Deep impact: Deep-sea wildlife more vulnerable to extinction than first thought
    on March 22, 2018 at 7:03 pm

    The existence of the unusual yeti crabs (Kiwaidae) -- a family of crab-like animals whose hairy claws and bodies are reminiscent of the abominable snowman -- since 2005, but already their future survival could be at risk. New Oxford University research suggests that past environmental changes may have profoundly impacted the geographic range and species diversity of this family. The findings indicate that such animals may be more vulnerable to the effects of human resource exploitation and climate change than initially thought. […]

  • Vital role of marine predators in supplying nutrients to coral reef ecology
    on March 21, 2018 at 4:16 pm

    It's long been known that sharks help nourish coral reefs, but exactly to what extent has never been scientifically mapped out -- until now. […]

  • 'We're sleepwalking into a mass extinction' say scientists
    on March 21, 2018 at 4:15 pm

    Species that live in symbiosis with others, which often occur in the most delicately balanced and threatened marine ecosystems such as coral reefs, are the slowest to recover their diversity if damaged, according to a team of scientists. […]

  • Hunting squid slowed by rising carbon levels
    on March 21, 2018 at 1:47 pm

    Scientists have found that high carbon dioxide levels cause squid to bungle attacks on their prey. Investigators said that the oceans absorb more than one-quarter of all the excess carbon dioxide (CO2) released into the atmosphere by humans and this uptake of additional CO2 causes seawater to become more acidic. […]

  • Seaweeds shelter calcifying marine life from acidifying oceans
    on March 21, 2018 at 1:26 pm

    Seaweeds create a chemical microenvironment at their surface, providing refuge for calcifying organisms that are at risk from decreasing oceanic pH, shows new research. […]

  • Marine researchers say recent sea star wasting disease epidemic defies prediction
    on March 20, 2018 at 6:13 pm

    Beginning in 2013, a mysterious disease crippled sea star populations up and down the U.S. west coast. Over a matter of months, many sea star species died in record-breaking numbers, though the ochre sea star was among the hardest hit. Now, researchers have analyzed just how much the populations of this species have declined, but they have not yet determined what factors might be contributing to the epidemic. […]

  • One step closer to understanding how tidal clocks tick
    on March 20, 2018 at 12:43 pm

    A comprehensive study on the rhythmicity of limpets -- mobile intertidal molluscs -- employing field and laboratory observations, as well assembling a clock oriented transcriptome -- shows that in the same way that these animals behave with a tidal rhythm, so too are a majority of their genes expressed in a tidal (and not circadian) rhythm, including some genes which were thought to play an important role in circadian clocks/timing. […]

  • New deep reef ocean zone, the rariphotic, teeming with new fish species
    on March 20, 2018 at 12:43 pm

  • Fish accounted for surprisingly large part of the Stone Age diet
    on March 19, 2018 at 4:05 pm

    New research can now show what Stone Age people actually ate in southern Scandinavia 10 000 years ago. The importance of fish in the diet has proven to be greater than expected. So, if you want to follow a Paleo diet -- you should quite simply eat a lot of fish. […]

  • Wandering greenhouse gas
    on March 16, 2018 at 4:11 pm

    On the seafloor of the shallow coastal regions north of Siberia, microorganisms produce methane when they break down plant remains. If this greenhouse gas finds its way into the water, it can also become trapped in the sea ice that forms in these coastal waters. […]

  • Coral reef experiment shows: Acidification from carbon dioxide slows growth
    on March 14, 2018 at 6:50 pm

    Ocean acidification will severely impair coral reef growth before the end of the century if carbon dioxide emissions continue unchecked. The paper represents the first ocean acidification experiment in which seawater was made artificially acidic by the addition of carbon dioxide and then allowed to flow across a natural coral reef community. The acidity of the seawater was increased to reflect end-of-century projections if carbon dioxide from greenhouse gas emissions are not abated. […]

  • Marine ecologists study the effects of giant kelp on groups of organisms in the underwater forest...
    on March 14, 2018 at 6:49 pm

    When British naturalist Charles Darwin traveled to the Galapagos Islands in 1835, he took notice of the giant kelp forests ringing the islands. He believed that if those forests were destroyed, a significant number of species would be lost. These underwater ecosystems, Darwin believed, could be even more important than forests on land. […]

  • Climatologists render skillful predictions of drought and food insecurity that help avert famine
    on March 14, 2018 at 6:49 pm

    Last year, 81 million people worldwide experienced severe food insecurity. About 80 percent of them live in Africa. While much of that food insecurity relates to civil war and violence in places like South Sudan and Nigeria, a good portion also stems from a sequence of five severe droughts that began in Ethiopia in 2015 and spread across parts of the continent in the ensuing three years. […]

  • Decreased oxygen levels could present hidden threat to marine species
    on March 14, 2018 at 1:23 pm

    Scientists have shown that creatures which develop in hypoxic (low oxygen) conditions in the marine environment could experience previously unseen hindered development, and become compromised as adults. […]

  • Climate change risk for half of plant and animal species in biodiversity hotspots
    on March 14, 2018 at 2:55 am

    Up to half of plant and animal species in the world's most naturally rich areas, such as the Amazon and the Galapagos, could face local extinction by the turn of the century due to climate change if carbon emissions continue to rise unchecked. Even if the Paris Climate Agreement 2°C target is met, these places could lose 25 percent of their species. Researchers examined the impact of climate change on nearly 80,000 plant and animal species in 35 areas. […]

  • A starfish cold case reopens, climate change remains suspect
    on March 13, 2018 at 7:21 pm

    As ocean temperatures rise and oceanic diseases proliferate, species like sea stars struggle to survive, and scientists are looking for underlying causes. To bring clarity to the sea star disease problem, the scientists propose a new, broad nomenclature. […]

  • Breeding trouble: Meta-analysis identifies fishy issues with captive stocks
    on March 13, 2018 at 12:42 pm

    A meta-analysis has found patterns that may be jeopardizing the long-term success of worldwide animal breeding programs, which increasingly act as an insurance against extinction in conservation, and for food security. Captive-born animals had, on average, almost half the odds of reproductive success compared to their wild-born counterparts in captivity; in aquaculture, the effects were particularly pronounced. The scientists were surprised by how universal the patterns were across the animal kingdom. […]

  • Color-changing hogfish 'sees' with its skin
    on March 13, 2018 at 12:16 am

    The hogfish can go from white to reddish in milliseconds as it adjusts to shifting conditions in the ocean. Scientists have long suspected that animals with quick-changing colors don't just rely on their eyes to tune their appearance to their surroundings -- they also sense light with their skin. But exactly how remains a mystery. A study reveals that hogfish skin senses light differently from eyes. […]

  • Marine charities net more than iconic fishery: Massachusetts
    on March 8, 2018 at 1:55 pm

    Massachusetts boasts one of the most iconic fisheries in the US, but new research suggests that protecting marine coastlines has surpassed commercial fishing as an economic driver. The study is the first to calculate the economic value of coastal preservation in Massachusetts. The research finds these efforts contributed $179 million to the state's economy in 2014, more than finfish landings ($105 million) and whale-watching ($111 million). […]
