  • How red-eared invaders are hurting California's native turtles
    on August 22, 2019 at 8:50 pm

    Western pond turtles got fatter and healthier after scientists removed nearly 200 invasive red-eared slider turtles from the UC Davis Arboretum, reports a new study. The study is the first to quantify competition between these two species in the wild.

  • What's killing sea otters? Parasite strain from cats
    on August 22, 2019 at 8:50 pm

    Many wild southern sea otters in California are infected with the parasite Toxoplasma gondii, yet the infection is fatal for only a fraction of sea otters, which has long puzzled the scientific community. A new study identifies the parasite's specific strains that are killing southern sea otters, tracing them back to a bobcat and feral domestic cats from nearby watersheds.

  • Profound patterns in globally important algae
    on August 20, 2019 at 7:29 pm

    A globally important ocean algae is mysteriously scarce in one of the most productive regions of the Atlantic Ocean, according to a new article. A massive dataset has revealed patterns in the regions where Atlantic coccolithophores live, illuminating the inner workings of the ocean carbon cycle and raising new questions.

  • Longline fishing hampering shark migration
    on August 20, 2019 at 2:15 pm

    Longline fisheries around the world are significantly affecting migrating shark populations, according to an international study. The study found that approximately a quarter of the studied sharks' migratory paths fell under the footprint of longline fisheries, directly killing sharks and affecting their food supply.

  • All-in-one: New microbe degrades oil to gas
    on August 20, 2019 at 12:18 pm

    The tiny organisms cling to oil droplets and perform a great feat: As a single organism, they may produce methane from oil by a process called alkane disproportionation. Previously this was only known from symbioses between bacteria and archaea. Scientists have now found cells of this microbe called Methanoliparia in oil reservoirs worldwide.

  • Tools to help manage seagrass survival
    on August 19, 2019 at 1:30 pm

    A new study has developed a statistical toolbox to help avoid seagrass loss which provides shelter, food and oxygen to fish and at-risk species like dugongs and green turtles.

  • Enriched environment in aquaculture enhances the survival of fish from bacterial disease
    on August 15, 2019 at 3:37 pm

    A new study has revealed that enriched rearing of juvenile fish significantly enhances the survival of fish from bacterial infection commonly seen in rearing conditions. That may also improve the post release survival of the fish after stocking into the wild.

  • Monster penguin find in Waipara, New Zealand
    on August 14, 2019 at 2:16 pm

    A new species of giant penguin -- about 1.6 metres tall -- has been identified from fossils found in Waipara, North Canterbury in New Zealand.

  • Unique dietary strategy of a tropical marine sponge
    on August 14, 2019 at 1:07 pm

    Research revealed a unique feeding strategy of a marine sponge, wherein the sponge animal acquires important components of its diet from symbiotic bacteria living within the sponge.

  • Microbes have adapted to live on food that is hundreds of years old
    on August 13, 2019 at 8:05 pm

    Microbial communities living in deep aquatic sediments have adapted to survive on degraded organic matter, according to a new study.

  • Key factors in how some algae harness solar energy
    on August 13, 2019 at 5:42 pm

    Scientists have discovered how diatoms -- a type of alga that produce 20 percent of the Earth's oxygen -- harness solar energy for photosynthesis. The discovery could help lead to more efficient and affordable algae-based biofuels and combat climate change from fossil fuel burning.

  • DNA tests of UK waters could help catch invasive species early
    on August 13, 2019 at 2:23 pm

    Scientists have discovered several artificially introduced species in the coastal waters of southern England, using a technique that could help the early detection of non-native species if adopted more widely.

  • Study examines a million corals one by one in urgent call to save reefs
    on August 12, 2019 at 6:49 pm

    Scientists have completed a landmark study on how to save coral reefs in the Indian and Pacific Oceans.

  • Asian carp capable of surviving in much larger areas of Lake Michigan than previously thought
    on August 12, 2019 at 1:45 pm

    Asian carp are capable of surviving and growing in much larger portions of Lake Michigan than scientists previously believed and present a high risk of becoming established, according to a new modeling study.

  • Green turtles eat plastic that looks like their food
    on August 9, 2019 at 12:57 pm

    Green turtles are more likely to swallow plastic that resembles their natural diet of sea grass, new research suggests.

  • Research on cholera adds to understanding of the social life of bacteria
    on August 9, 2019 at 12:57 pm

    Strains of the bacterium Vibrio cholerae transform themselves from small, comma-shaped cells to long filaments in nutrient-poor environments to aid short-term survival.

  • 88 percent decline of big freshwater animals
    on August 8, 2019 at 3:51 pm

    Scientists have now quantified the global decline of big freshwater animals: From 1970 to 2012, global populations of freshwater megafauna declined by 88 percent - twice the loss of vertebrate populations on land or in the ocean. Large fish species are particularly affected.

  • These sharks use unique molecules to glow green
    on August 8, 2019 at 3:14 pm

    In the depths of the sea, certain shark species transform the ocean's blue light into a bright green color that only other sharks can see -- but how they biofluoresce has previously been unclear. Researchers have now identified what's responsible for the sharks' bright green hue: a previously unknown family of small-molecule metabolites.

  • Marine heatwaves a bigger threat to coral reefs than previously thought, scientists find
    on August 8, 2019 at 3:14 pm

    Marine heatwaves are a much bigger threat to coral reefs than previously thought, research revealing a previously unrecognized impact of climate change on coral reefs has shown.

  • Stony corals: Limits of adaption
    on August 8, 2019 at 2:38 pm

    Corals have been dominant framework builders of reef structures for millions of years. Ocean acidification, which is intensifying as climate change progresses, is increasingly affecting coral growth. Scientists have now answered some questions regarding whether and how corals can adapt to these changes by having gained important insights into the regulatory processes of coral calcification.
