  • Global analysis reveals how sharks travel the oceans to find food
    on January 18, 2018 at 7:29 pm

    You’ve heard of “you are what you eat” - this research shows that for sharks, the more relevant phrase is “you are where you ate.&rdquo […]

  • Recent advances in understanding coral resilience are essential to safeguard coral reefs
    on January 18, 2018 at 7:19 pm

    The most urgent course of action to safeguard coral reefs is to reduce global greenhouse gas emissions, but concurrently there is also a need to consider novel management techniques and previously over-looked reef areas for protective actions under predicted climate change impacts. The conclusions were reached following a comprehensive review of the literature on the mechanisms of potential coral resistance and recovery across scales from global reef areas to the microbial level within individual corals. […]

  • Warming Arctic climate constrains life in cold-adapted mammals
    on January 18, 2018 at 3:08 pm

    A new study has uncovered previously unknown effects of rain-on-snow events, winter precipitation and ice tidal surges on the muskoxen. […]

  • Aid for oceans and fisheries in developing world drops by 30 percent
    on January 17, 2018 at 9:40 pm

    Financial aid to fisheries in developing countries has declined by 30 percent, finds a new study. Projects focusing on climate issues in fisheries had a 77 percent decline over the five years studied. […]

  • Exposure to water that is both salty and fresh is key to future success
    on January 17, 2018 at 6:54 pm

    According to Charles Darwin the ability to adapt to new conditions is essential for survival of species. The capacity to cope with altered conditions is becoming increasingly important in the face of climate change. New evidence on salt water tolerance in spawning migrating pike from the Baltic Sea suggests that not being adapted to specific local environments may promote persistence in an uncertain, rapidly changing world. […]

  • Scale-eating fish adopt clever parasitic methods to survive
    on January 17, 2018 at 6:51 pm

    A small group of fishes -- possibly the world's cleverest carnivorous grazers -- feeds on the scales of other fish in the tropics. Biologists are trying to understand these scale-feeding fish and how this odd diet influences their body evolution and behavior. […]

  • Coping with climate stress in Antarctica
    on January 17, 2018 at 5:16 pm

    Some Antarctic fish living in the planet's coldest waters are able to cope with the stress of rising carbon dioxide levels the ocean. They can even tolerate slightly warmer waters. But they can't deal with both climate change stressors at the same time, according to a new study. […]

  • California sea lion population rebounded to new highs
    on January 17, 2018 at 4:50 pm

    California sea lions have fully rebounded under the protection of the Marine Mammal Protection Act, with their population on the West Coast reaching carrying capacity in 2008 before unusually warm ocean conditions reduced their numbers, according to the first comprehensive population assessment of the species. […]

  • Nanowrinkles could save billions in shipping and aquaculture
    on January 17, 2018 at 2:23 pm

    Biofouling costs shipping billions in increased fuel costs and affects aquaculture. A nanostructured surface inspired by the carnivorous pitcher plant could slash those costs. […]

  • No-fishing zones help endangered penguins
    on January 17, 2018 at 3:25 am

    Small no-fishing zones around colonies of African penguins can help this struggling species, new research shows. […]

  • Drones confirm importance of Costa Rican waters for sea turtles
    on January 16, 2018 at 8:12 pm

    A new drone-enabled population survey -- the first ever on sea turtles -- shows that larger-than-anticipated numbers of turtles aggregate in waters off Costa Rica's Ostional National Wildlife Refuge. Scientists estimate turtle densities may reach up to 2,086 animals per square kilometer. The study underscores the importance of the Ostional habitat; it also confirms that drones are a reliable tool for surveying sea turtle abundance. […]

  • Surfers three times more likely to have antibiotic-resistant bacteria in guts
    on January 15, 2018 at 2:42 pm

    Scientists compared fecal samples from surfers and non-surfers to assess whether the surfers' guts contained E. coli bacteria that were able to grow in the presence of the antibiotic cefotaxime. Cefotaxime has previously been prescribed to kill off these bacteria, but some have acquired genes that enable them to survive this treatment. The study found that 13 of 143 (9 percent) of surfers were colonized by these resistant bacteria, compared to just four of 130 (3 percent) of non-surfers swabbed. […]

  • Robots aid better understanding of phytoplankton blooms
    on January 15, 2018 at 2:42 pm

    Phytoplankton blooms are one of the most important factors contributing to the efficiency of the carbon pump in the North Atlantic Ocean. To better understand this phenomenon, researchers have developed a new class of robots able to collect data in the ocean throughout the year. Using these unparalleled data, the researchers have identified the starting point for the explosive spring phytoplankton bloom. […]

  • New application for acoustics helps estimate marine life populations
    on January 15, 2018 at 2:42 pm

    Researchers have for the first time have used hydroacoustics as a method for comparing the abundance of fishes within and outside marine protected areas (MPAs). […]

  • Genes that aid spinal cord healing in lamprey also present in humans, researchers discover
    on January 15, 2018 at 2:42 pm

    Many of the genes involved in natural repair of the injured spinal cord of the lamprey are also active in the repair of the peripheral nervous system in mammals, according to a new study. […]

  • Species identification in the water bottle
    on January 12, 2018 at 3:51 pm

    Environmental DNA analysis makes it possible to detect water organisms without having to capture them first. For the first time, researchers systematically investigated the effect of various environmental factors on environmental DNA analyses. By doing so, the researchers have made an important step towards the standardized application of this method for the monitoring of water bodies. […]

  • Tagged tiger shark proving unstoppable
    on January 11, 2018 at 9:30 pm

    For more than a decade, researchers have been tagging and tracking sharks in order to study their migratory patterns and more. One tiger shark - Andy - is now the longest-ever tracked tiger shark, providing years worth of data for researchers. […]

  • Rising CO2 is causing trouble in freshwaters too, study suggests
    on January 11, 2018 at 7:17 pm

    As carbon dioxide (CO2) levels in the atmosphere rise, more CO2 gets absorbed into seawater. As a result, the world's oceans have grown more acidic over time, causing a wide range of well-documented problems for marine animals and ecosystems. Now, researchers present some of the first evidence that similar things are happening in freshwaters too. […]

  • Rising temperatures turning major sea turtle population female
    on January 11, 2018 at 3:14 pm

    Scientists have used a new research approach to show that warming temperatures are turning one of the world's largest sea turtle colonies almost entirely female, running the risk that the colony cannot sustain itself in coming decades, newly published research concludes. […]

  • Body size of marine plankton, currents keys to dispersal in ocean
    on January 10, 2018 at 6:23 pm

    A new international study found that the size of plankton, and the strength and direction of currents, are key to how they are dispersed in the ocean -- much more so than physical conditions including differences in temperature, salinity and nutrient availability. […]
