  • Deep-sea worms and bacteria team up to harvest methane
    on April 3, 2020 at 8:27 pm

    Scientists uncover an unusual partnership at the bottom of the ocean.

  • Tooth be told: Earless seals existed in ancient Australia
    on April 3, 2020 at 2:40 pm

    A fossilised seal tooth, dating back approximately three million years, found on a Victorian beach proves earless seals existed in Australia in prehistoric times. Known as monachines, the seals became extinct due to rapid changes in sea level.

  • Coastal pollution reduces genetic diversity of corals, reef resilience
    on April 3, 2020 at 12:28 pm

    A new study found that human-induced environmental stressors have a large effect on the genetic composition of coral reef populations in Hawai'i. They confirmed that there is an ongoing loss of sensitive genotypes in nearshore coral populations due to stressors resulting from poor land-use practices and coastal pollution. This reduced genetic diversity compromises reef resilience. 

  • Our oceans are suffering, but we can rebuild marine life
    on April 2, 2020 at 2:08 pm

    It's not too late to rescue global marine life, according to a study outlining the steps needed for marine ecosystems to recover from damage by 2050. The study found many components of marine ecosystems could be rebuilt if we try harder to address the causes of their decline.

  • Six decades of change in plankton communities
    on April 2, 2020 at 2:08 pm

    New research shows that some species have experienced a 75% population decrease in the past 60 years, while others are more than twice as abundant due to rises in sea surface temperatures.

  • Fish have diverse, distinct gut microbiomes
    on April 1, 2020 at 5:08 pm

    The rich biodiversity of coral reefs even extends to microbial communities within fish, according to new research. The study reports that several important grazing fish on Caribbean coral reefs each harbor a distinct microbial community within their guts, revealing a new perspective on reef ecology.

  • About the distribution of biodiversity on our planet
    on April 1, 2020 at 5:08 pm

    Large open-water fish predators such as tunas or sharks hunt for prey more intensively in the temperate zone than near the equator. With this result, a study is challenging a long-standing explanation for the distribution of biodiversity on our planet.

  • Surprising hearing talents in cormorants
    on April 1, 2020 at 5:07 pm

    The great cormorant has more sensitive hearing under water than in air. This new knowledge may help protect vulnerable bird species.

  • Animal camouflage: Natural light flicker can help prevent detection
    on April 1, 2020 at 2:58 pm

    Movement breaks camouflage, making it risky for anything trying to hide. New research has shown that dynamic features common in many natural habitats, such as moving light patterns, can reduce being located when moving.

  • Smaller than expected phytoplankton may mean less carbon sequestered at sea bottom
    on April 1, 2020 at 1:26 pm

    A study that included the first-ever winter sampling of phytoplankton in the North Atlantic revealed cells smaller than what scientists expected, meaning carbon sequestration models may be too optimistic.

  • Cooperative male dolphins match the tempo of each other's calls
    on March 31, 2020 at 11:44 pm

    When it comes to working together, male dolphins coordinate their behavior just like us. New findings provide insight into the importance of physical and vocal coordination in alliance forming animals.

  • Well-engineered 'watercourts' stored live fish, fueling Florida's Calusa kingdom
    on March 30, 2020 at 10:16 pm

    Fishing powered the mighty Calusa, who ruled South Florida for centuries. Now, a new study shows how sophisticatedly engineered 'watercourts' served as holding pens for live fish, sustaining Calusa population growth and large-scale construction projects.

  • Water pressure: Ancient aquatic crocs evolved, enlarged to avoid freezing
    on March 30, 2020 at 10:16 pm

    Ancient crocodilian ancestors that abandoned land for water nearly 200 million years ago supposedly got larger because they were released from the constraints of gravity, territory and diet. But a new study suggests that the upper bounds of size in aquatic vs. landlocked crocs were similar -- and that smaller aquatic species got larger mostly to avoid freezing in the frigid, heat-stealing depths.

  • Sturgeon genome sequenced
    on March 30, 2020 at 7:21 pm

    Sturgeons lived on earth already 300 million years ago and yet their external appearance seems to have undergone very little change. A team of researchers has now succeeded in sequencing their genome, delivering a missing piece of the puzzle essential to understanding the ancestry of vertebrates.

  • In Earth's largest extinction, land animal die-offs began long before marine extinction
    on March 27, 2020 at 8:17 pm

    Because of poor dates for land fossils laid down before and after the mass extinction at the end of the Permian, paleontologists assumed that the terrestrial extinctions from Gondwana occurred at the same time as the better-documented marine extinctions. But a new study provides more precise dates for South African fossils and points to a long, perhaps 400,000-year period of extinction on land before the rapid marine extinction 252 million years ago.

  • Scientists predict the size of plastics animals can eat
    on March 27, 2020 at 3:37 pm

    A team of scientists has, for the first time, developed a way of predicting the size of plastics different animals are likely to ingest.

  • Animals keep viruses in the sea in balance
    on March 27, 2020 at 3:36 pm

    A variety of sea animals can take up virus particles while filtering seawater for oxygen and food. Sponges are particularly efficient.

  • Coral tells own tale about El Niño's past
    on March 26, 2020 at 6:44 pm

    Scientists use data from ancient coral to build a record of temperatures in the tropical Pacific Ocean over the last millennium. The data question previous links between volcanic eruptions and El Niño events.

  • Neanderthals ate mussels, fish, and seals too
    on March 26, 2020 at 6:44 pm

    Over 80,000 years ago, Neanderthals fed themselves on mussels, fish and other marine life. The first evidence has been found by an international team in the cave of Figueira Brava in Portugal. The excavated layers date from 86,000 to 106,000 years ago, the period when Neanderthals settled in Europe. Sourcing food from the sea at that time had only been attributed to anatomically modern humans in Africa.

  • What can be learned from the microbes on a turtle's shell?
    on March 26, 2020 at 6:44 pm

    Researchers have found that a unique type of algae, usually only seen on the shells of turtles, affects the surrounding microbial communities. It is hoped that these findings can be applied to support the conservation of turtles. Previous research has shown that a diverse microbiome can protect animals against infections.
