  • Chemical pollutants disrupt reproduction in anemonefish
    on December 5, 2021 at 4:17 pm

    Ocean pollution is unfortunately becoming more commonplace, raising concerns over the effect of chemicals that are leaching into the water. In a new study, researchers have discovered how these chemicals can affect the reproduction in common anemonefish Amphiprion ocellaris.

  • Forty percent of North Atlantic right whale population using Gulf of Saint Lawrence as seasonal habitat
    on December 2, 2021 at 8:39 pm

    A new study confirms that the Gulf of St. Lawrence is an important habitat for a large proportion of the endangered North Atlantic right whale population.

  • How does the climate crisis affect the Antarctic fur seal?
    on December 2, 2021 at 4:34 pm

    The climate crisis is limiting the availability of krill -- small crustaceans that are vital in the marine food chain -- during summer in some areas of the Antarctica. This involves a decrease in the food abundance for female Antarctic fur seals in summer and a decrease in their reproductive success. Moreover, the predation of pups by the leopard seal has also increased due to a lower abundance of penguins, the main prey of this voracious Antarctic predator. However, the impact of the climate crisis on the Antarctic fur seal in winter has been ignored to date, when the cold, wind and ice make it harder to study the Antarctic ecosystems.

  • Volcanic fertilization of the oceans drove severe mass extinction
    on December 2, 2021 at 4:32 pm

    Scientists have discovered that two intense spells of volcanic activity triggered a period of global cooling and falling oxygen levels in the oceans, which caused one of the most severe mass extinctions in Earth history - the 'Late Ordovician Mass Extinction', 450 million years ago.

  • Ocean plastic is creating new communities of life on the high seas
    on December 2, 2021 at 2:29 pm

    Coastal plants and animals have found a new way to survive in the open ocean -- by colonizing plastic pollution. A new commentary reports coastal species growing on trash hundreds of miles out to sea in the North Pacific Subtropical Gyre, more commonly known as the 'Great Pacific Garbage Patch.'

  • From corals to humans, a shared trigger for sperm to get in motion
    on December 1, 2021 at 9:20 pm

    Coral sperm require a specific pH to move, which identified a signaling pathway that is shared by organisms including humans. The results have implications for how corals may fare in shifting marine conditions due to climate change.

  • Headwater refuges: Combined effect of drought and fire on stream communities
    on December 1, 2021 at 6:36 pm

    Life is water, and water is life. This truism certainly applies to the Pacific coast, where streams and rivers function as the region's arteries. The water they carry fosters plant life and wildlife in Southern California's Mediterranean climate. They provide sanctuary during droughts and often serve as the nexus for recovery after fires.

  • When variations in Earth's orbit drive biological evolution
    on December 1, 2021 at 4:19 pm

    Coccolithophores are microscopic algae that form tiny limestone plates, called coccoliths, around their single cells. They are responsible for half of the limestone produced in the oceans and therefore play a major role in the carbon cycle and in determining ocean chemistry. A team of scientists show that certain variations in Earth's orbit have influenced the evolution of coccolithophores.

  • Researchers unlock biogeographical secrets of deep-sea limpets
    on December 1, 2021 at 4:19 pm

    Researchers have decoded for the first time the demographic history, genetic structure, and population connectivity of a deep-sea limpet widely distributed in vent and seep ecosystems in the Northwest Pacific. This study not only enhances our knowledge of the historical population divergence and contemporary gene flow of deep-sea organisms under the intricate interactions amongst local habitats, seafloor topography, and ocean currents, but also serves as a scientific basis for better conservation of marine biodiversity and more effective environmental management.

  • Holistic framework can assess fisheries’ strengths and potential weaknesses
    on November 30, 2021 at 6:02 pm

    A new decision-making framework designed by an international team of fisheries researchers can help fisheries bolster their ability to adapt to a warming world. The tool is meant to take a lot of the guesswork out of finding resilience in a time of climate change.

  • Three-body interactions bring egoists into the collective comfort zone – even penguins
    on November 30, 2021 at 3:15 pm

    A research team has examined the group dynamics of communicating active particles. These particles are consistently focused on self-optimization. By always endeavoring to maintain their own personal comfort, they also help the other group members. Such self-optimization is a common multi-body phenomenon which can occur for penguins and bacteria.

  • Extinct swordfish-shaped marine reptile discovered
    on November 29, 2021 at 8:50 pm

    Researchers have discovered a new marine reptile. The specimen, a stunningly preserved meter-long skull, is one of the last surviving ichthyosaurs -- ancient animals that look eerily like living swordfish.

  • Snow monkeys go fishing to survive harsh Japanese winters
    on November 29, 2021 at 5:27 pm

    Snow monkeys living in one of the world's coldest regions survive by 'going fishing' -- scooping live animals, including brown trout, out of Japanese rivers and eating them to stay alive, a new study reveals.

  • Arctic krill respond to visual changes during Arctic night
    on November 29, 2021 at 5:23 pm

    New research finds that Arctic krill have a biological response to changes in light. When it is lightest in the Arctic polar night, usually around the middle of the day known as midday twilight, the krill know to swim down to the bottom in order to hide from predators. When it is darkest in the Arctic polar night, that's when they swim to the surface in search of bioluminescent food.

  • Researchers identify behavioral adaptations that may help Antarctic fishes adapt to warming Southern Ocean
    on November 29, 2021 at 3:56 pm

    Scientists describe how Antarctic fishes with and without hemoglobin react to acute thermal stress. The responses may help the fish withstand the impacts of climate change.

  • Jaws of defeat: Anglers’ emotions toward shark depredation is key to conservation
    on November 26, 2021 at 6:08 pm

    In a broad-scale study researchers quantified the emotional and behavioral responses to shark depredation in recreational fisheries. The study found that anglers, and especially recreational fishing guides, who experienced depredation were more likely to have a negative response towards sharks and were thus more likely to target sharks for additional harvesting.

  • Remote ocean wilderness areas are 'living time machines,' teeming with large fish
    on November 22, 2021 at 10:27 pm

    A new, widespread study of the global state of marine coral reef wilderness by WCS, NGS, and university collaborators found that remote ocean wilderness areas are sustaining fish populations much better than some of the world's best marine reserves.

  • Different kinds of marine phytoplankton respond differently to warming ocean temperatures
    on November 18, 2021 at 2:16 am

    A team of researchers has concluded that different types of phytoplankton will react differently to increasing ocean temperatures resulting from the changing climate. An examination of how four key groups of phytoplankton will respond to ocean temperatures forecast to occur between 2080 and 2100 suggests that their growth rates and distribution patterns will likely be dissimilar, resulting in significant implications for the future composition of marine communities around the globe.

  • A new approach to identify mammals good at learning sounds
    on November 16, 2021 at 3:31 pm

    Why are some animals good at learning sounds? Did this skill appear when animals started 'faking' their body size by lowering calls? In a new study on a wide range of mammals,researchers revisit this question. Surprisingly, many animals who are skilled vocalists (such as dolphins and seals) actually sound higher than would be expected for their body size.

  • Climate change will destroy familiar environments, create new ones and undermine efforts to protect sea life
    on November 12, 2021 at 3:05 pm

    Climate change is altering familiar conditions of the world's oceans and creating new environments that could undermine efforts to protect sea life in the world's largest marine protected areas.
