  • Killer whale grandmothers boost survival of calves
    on December 9, 2019 at 9:13 pm

    New research finds that killer whale grandmothers who were no longer able to reproduce had the biggest beneficial impact on the survival chances of their grand-offspring. This may be because grandmothers without calves of their own are free to focus time and resources on the latest generation, the researchers suggest.

  • New England fishermen losing jobs due to climate fluctuations
    on December 9, 2019 at 9:13 pm

    For decades the biggest threat to the industry has been overfishing, but it is no longer the only threat. According to new research, fluctuations in the climate have already cost some New England fishermen their jobs. This specific effect of climate is distinct from the overall job losses and gains caused by other factors, such as changes in market demand, regulatory changes to curb overfishing, and broader economic trends.

  • Island 'soundscapes' show potential for evaluating recovery of nesting seabirds
    on December 6, 2019 at 4:28 pm

    An important tool for monitoring seabird populations involves acoustic sensors deployed at nesting sites to record sounds over long periods of time. But analysis of the recordings to identify and count the calls of different species can be time-consuming, even with computers and artificial intelligence. An alternative approach is to evaluate all of the sounds in an environment as a 'soundscape', using features such as acoustic diversity, complexity, and intensity as indicators of ecosystem health.

  • Scientists at the California Academy of Sciences describe 71 new species in 2019
    on December 5, 2019 at 8:58 pm

    From geckos to goblin spiders, flowering plants, and Mediterranean ants -- spanning five continents and three oceans -- these 71 new species described by Academy scientists grow Earth's tree of life.

  • Whales may owe their efficient digestion to millions of tiny microbes
    on December 5, 2019 at 6:05 pm

    A study shows that the microbial communities inside whales may play an important role in the digestion of one of the ocean's most abundant carbon-rich lipids, known as a wax ester.

  • Lights on fishing nets save turtles and dolphins
    on December 5, 2019 at 4:31 pm

    Placing lights on fishing nets reduces the chances of sea turtles and dolphins being caught by accident, new research shows.

  • Gulf of Mexico coral reefs to protect from storm surge in the future -- But will they?
    on December 4, 2019 at 10:03 pm

    Researchers used 120,000-year-old fossils to predict how Gulf of Mexico coral reefs will respond to climate change toward the end of this century.

  • How do world's smallest sea turtles become stranded in Cape Cod?
    on December 4, 2019 at 8:28 pm

    A computational analysis has surfaced new insights into the wind and water conditions that cause Kemp's ridley sea turtles to become stranded on beaches in Cape Cod, Massachusetts.

  • For some corals, meals can come with a side of microplastics
    on December 3, 2019 at 7:52 pm

    A new experiment has found that some corals are more likely to eat microplastics when they are consuming other food, yet microplastics alone are undesirable.

  • Great Barrier Reef study shows how reef copes with rapid sea-level rise
    on December 3, 2019 at 4:45 pm

    A survey of coral reef cores on the Great Barrier Reef has revealed how it has responded to recent periods of rapid sea-level rise. The study, covering the past 9000 years, has revealed a system in delicate balance.

  • Compound eyes: The visual apparatus of today's horseshoe crabs goes back 400 million years
    on December 3, 2019 at 3:20 pm

    The extinct sea scorpion species Jaekelopterus rhenaniae had eyes comparable to those of today's horseshoe crabs. The two-and-a-half-meter predator was particularly apt at perceiving contrasts and contours under water.

  • Whaling and climate change led to 100 years of feast or famine for Antarctic penguins
    on December 3, 2019 at 2:10 pm

    New research reveals how penguins have dealt with more than a century of human impacts in Antarctica and why some species are winners or losers in this rapidly changing ecosystem.

  • Through the eyes of animals
    on December 3, 2019 at 1:29 pm

    Humans are now closer to seeing through the eyes of animals, thanks to an innovative software framework.

  • Female fish can breed a new species if they aren't choosy about who is Mr. Right
    on December 3, 2019 at 1:29 pm

    Female fish can breed a new species if they aren't choosy about who is Mr. Right. Fish will mate with a species outside their own if the male's coloring is attractive enough or if the female can't see him properly, according to new research. Such 'mistakes' in mate choice can lead to the evolution of new species, an international team of scientists found after they analyzed the DNA of more than 400 cichlid fish.

  • Harbor porpoise calves exposed to neurotoxic PCBs in mothers' milk
    on December 3, 2019 at 12:04 am

    Harbour porpoise calves around the UK are carrying a more neurotoxic cocktail of PCBs than their mothers, as females unknowingly detoxify themselves by transferring the chemicals while feeding their young, new research reveals today.

  • Integrated approach for managing aquatic invasive species in california
    on December 3, 2019 at 12:04 am

    Though small and somewhat nondescript, quagga and zebra mussels pose a huge threat to local rivers, lakes and estuaries. Thanks to aggressive measures to prevent contamination, Santa Barbara County's waters have so far been clear of the invasive mollusks, but stewards of local waterways, reservoirs and water recreation areas remain vigilant to the possibility of infestation by these and other non-native organisms.

  • Bacterial communities 'hitchhiking' on marine plastic trash
    on December 2, 2019 at 3:58 pm

    Using an innovative microscopy method, scientists have revealed the structure of the microbial communities coating microplastic trash collected from a variety of ocean sites.

  • When reefs die, parrotfish thrive
    on December 2, 2019 at 1:16 pm

    In contrast to most other species, reef-dwelling parrotfish populations boom in the wake of severe coral bleaching. The surprise finding came when researchers looked at fish populations in severely bleached areas of two reefs -- the Great Barrier Reef in the western Pacific and the Chagos Archipelago in the Indian Ocean.

  • Sounds of the past give new hope for coral reef restoration
    on November 30, 2019 at 2:20 pm

    Young fish can be drawn to degraded coral reefs by loudspeakers playing the sounds of healthy reefs, according to new research.

  • Animals could help humans monitor oceans
    on November 28, 2019 at 2:51 am

    Sharks, penguins, turtles and other seagoing species could help humans monitor the oceans by transmitting oceanographic information from electronic tags.
