  • The complex fate of Antarctic species in the face of a changing climate
    on June 17, 2019 at 11:17 am

    Researchers have presented support for the theory that marine invertebrates with larger body size are generally more sensitive to reductions in oxygen than smaller animals, and so will be more sensitive to future global climate change. However, evolutionary innovation can to some extent offset any respiratory disadvantages of large body size. […]

  • Squid could thrive under climate change
    on June 13, 2019 at 4:37 pm

    When scientists subjected two-toned pygmy squid and bigfin reef squid to carbon dioxide levels projected for the end of the century, they received some surprising results. […]

  • Rising sea levels destroyed evidence of shell middens at many prehistoric coastal sites
    on June 12, 2019 at 6:14 pm

    In a new study, researchers confirm a theory from the 1970s that coastal hunter-gatherers processed much of their shellfish at the beach before returning with their meat to camps on higher ground, leaving the heavy shells by the water. This finding has dramatic implications for past analyses of hunter-gatherer diets -- because many beachside shell middens would now be destroyed or underwater due to past sea level rises since the last Ice Age. […]

  • Protecting coral reefs in a deteriorating environment
    on June 12, 2019 at 6:13 pm

    A new report examines novel approaches for saving coral reefs imperiled by climate change, and how local decision-makers can assess the risks and benefits of intervention. […]

  • Dolphins form friendships through shared interests just like us, study finds
    on June 12, 2019 at 1:39 pm

    When it comes to making friends, it appears dolphins are just like us and form close friendships with other dolphins that have a common interest. The research provides further insight into the social habits of these remarkable animals. […]

  • Fifty years later, DDT lingers in lake ecosystems
    on June 12, 2019 at 12:44 pm

    To control pest outbreaks, airplanes sprayed more than 6,280 tons of dichlorodiphenyltrichloroethane (DDT) onto forests in New Brunswick, Canada, between 1952 and 1968, according to Environment Canada. By 1970, growing awareness of the harmful effects of DDT on wildlife led to curtailed use of the insecticide in the area. However, researchers have now shown that DDT lingers in sediments from New Brunswick lakes, where it could alter zooplankton communities. […]

  • Why Noah's Ark won't work
    on June 12, 2019 at 12:43 pm

    Many species will need large population sizes to survive climate change and ocean acidification, a new study finds. […]

  • Climate change benefits for giant petrels
    on June 12, 2019 at 12:43 pm

    Giant petrels will be 'temporary' winners from the effects of climate change in the Antarctic region -- but males and females will benefit in very different ways, a new study shows. […]

  • Skinny cod and grey seal reveals troubling changes to food web in the Baltic Sea
    on June 11, 2019 at 12:18 pm

    The prime predators of the Baltic Sea at the top of the food web are losing weight, according to a new study that links the deteriorating health of gray seals and cod with changes in bottom-living crustaceans, isopods and amphipods. […]

  • Deceptively simple: Minute marine animals live in a sophisticated symbiosis with bacteria
    on June 10, 2019 at 3:34 pm

    Trichoplax, one of the simplest animals on Earth, lives in a highly specific and intimate symbiosis with two types of bacteria. One, Grellia, is related to parasitic bacteria that cause typhus and Rocky Mountain spotted fever. However, it does not appear to harm Trichoplax. The other, Ruthmannia, sits inside the cells Trichoplax uses to digest its food. This symbiosis provides a window into microbial dark matter. […]

  • Rapid change in coral reefs prompts global calls for a rethink
    on June 7, 2019 at 3:04 pm

    Coral reef experts from around the world are calling for an urgent re-evaluation of our climate goals in the light of increasing evidence of unprecedented speed of change to these fragile ecosystems. […]

  • Fishers keen to help address the problem of marine litter
    on June 7, 2019 at 1:10 pm

    Commercial fishers are acutely aware of the potential for marine litter to cause lasting damage to their catches and the wider industry, a new study suggests. […]

  • New model predicts impact of invasive lionfish predators on coral reefs
    on June 6, 2019 at 10:32 pm

    A new model is providing insight into the impact of invasive lionfish on coral reefs in the Atlantic Ocean and Caribbean Sea. The venomous predatory fish has invaded more than 7.3 million square kilometers in the Atlantic and Caribbean, wreaking havoc among native fish populations. […]

  • Toxic metals found in reproductive organs of critically endangered eels
    on June 6, 2019 at 2:18 pm

    European eels consume their own skeletons as they swim 6,000 kilometers to their spawning grounds. The process is depositing toxic metals in the eels' reproductive organs, threatening their survival. […]

  • Surprising enzymes found in giant ocean viruses
    on June 5, 2019 at 7:42 pm

    A new study furthers our knowledge of viruses -- in the sea and on land -- and their potential to cause life-threatening illnesses. The findings, which examine newly-identified genes carried by mysterious 'giant' viruses, could represent potential new drug targets for giant viruses linked to human diseases. […]

  • Researchers discover what makes deep-sea dragonfish teeth transparent
    on June 5, 2019 at 5:35 pm

    The transparent teeth of the deep-sea dragonfish help camouflage the dragonfish from their prey. The unique adaptation results from their teeth having an unusually crystalline nanostructure mixed with amorphous regions. […]

  • Microorganisms on microplastics
    on June 5, 2019 at 4:16 pm

    A recent study shows that that the potentially toxin-producing plankton species Pfiesteria piscicida prefers to colonize plastic particles, where they are found in 50 times higher densities than in the surrounding water of the Baltic Sea and densities about two to three times higher than on comparable wood particles floating in the water. […]

  • How deep-ocean vents fuel massive phytoplankton blooms
    on June 5, 2019 at 2:03 pm

    A new study suggests vents in the seafloor may affect life near the ocean's surface and the global carbon cycle more than previously thought. It's the first to show how iron rising from beneath Earth's crust stimulates massive phytoplankton blooms. […]

  • Cardinalfish caught sneaking a bit on the side
    on June 5, 2019 at 2:03 pm

    Scientists reveal the torrid, adulterous love lives of the mouth-brooding cardinalfish. The male fish of this species carries the eggs in his mouth until they are ready to hatch. Until now the species were assumed to be monogamous. However, cuckoldry goes hand-in-hand with cannibalism of the young. […]

  • Snout dated: Slow-evolving elephant shark offers new insights into human physiology
    on June 4, 2019 at 9:26 pm

    Using different steroid hormones to activate a hormone receptor in a cartilaginous fish provides insights into origins and later evolution of crucial mechanism for survival of vertebrates living on land. […]
