Published Even inactive smokers are densely colonized by microbial communities
(via sciencedaily.com) Original source Everything is everywhere -- under certain conditions microbial communities can grow and thrive, even in places that are seemingly uninhabitable. This is the case at inactive hydrothermal vents on the sea floor. An international team is presently working to accurately quantify how much inorganic carbon can be bound in these environments.
Published Protein fragments ID two new 'extremophile' microbes--and may help find alien life
(via sciencedaily.com) Original source Perfectly adapted microorganisms live in extreme environments from deep-sea trenches to mountaintops. Learning more about how these extremophiles survive in hostile conditions could inform scientists about life on Earth and potential life on other planets.
Published Shark-bitten orcas in the Northeastern Pacific could be a new population of killer whale
(via sciencedaily.com) Original source Researchers believe a group of killer whales observed hunting marine mammals including sperm whales, as well as a sea turtle, in the open ocean off California and Oregon could be a new population. Based on available evidence, the researchers posit that the 49 orcas could belong to a subpopulation of transient killer whales or a unique oceanic population found in waters off the coast of California and Oregon.
Published Groundbreaking study reveals extensive leatherback turtle activity along U.S. coastline
(via sciencedaily.com) Original source A new study provides groundbreaking findings that offer insights on the migration and foraging patterns of leatherback sea turtles along the Northwest Atlantic shelf.
Published Diverse habitats help salmon weather unpredictable climate changes
(via sciencedaily.com) Original source Restored salmon habitat should resemble financial portfolios, offering fish diverse options for feeding and survival so that they can weather various conditions as the climate changes, a new study shows.
Published Researchers can reveal illegal timber exports
(via sciencedaily.com) Original source A new method of timber analysis can confidently identify the location in which the tree was harvested. The method has been developed with the aim of combating illegal timber imports from Russia and Belarus.
Published With discovery of roundworms, Great Salt Lake's imperiled ecosystem gets more interesting
(via sciencedaily.com) Original source Biologists announce the discovery of numerous species of roundworm in the highly saline waters of Great Salt Lake, the vast terminal lake in northwestern Utah that supports millions of migratory birds. Previously, brine shrimp and brine flies were the only known multicellular animals living in the water column. The scientists found nematodes, belonging to a family known for inhabiting extreme environments, in the lake's microbialites, reef-like structures covering about a fifth of the lakebed.
Published Marine heat waves disrupt the ocean food web in the northeast Pacific Ocean
(via sciencedaily.com) Original source Marine heat waves in the northeast Pacific Ocean create ongoing and complex disruptions of the ocean food web that may benefit some species but threaten the future of many others, a new study has shown.
Published High resolution imagery advances the ability to monitor decadal changes in emperor penguin populations
(via sciencedaily.com) Original source Emperor penguin populations have been exceedingly difficult to monitor because of their remote locations, and because individuals form breeding colonies on seasonal sea ice fastened to land (known as fast ice) during the dark and cold Antarctic winter. New research that incorporates very high-resolution satellite imagery with field-based validation surveys and long-term data has provided the first multi-year time series that documents emperor penguin global population trends.
Published Sonic youth: Healthy reef sounds increase coral settlement
(via sciencedaily.com) Original source Healthy coral reefs have rich soundscapes, full of the croaks, purrs, and grunts of various fishes and the crackling of snapping shrimp. Larval coral uses these sounds as cues to identify the best places to settle and grow. The authors found that sound could potentially be a vital tool in the effort to restore coral reefs. Broadcasting the sounds of a healthy reef to a reef that is degraded encourages coral larvae to settle there. This indicates that it's possible that 'acoustic enrichment' can be a key intervention to support imperiled reefs.
Published Summer solstice triggers synchronized beech tree reproduction across Europe
(via sciencedaily.com) Original source A new study has found that the summer solstice acts as a 'starting gun' to synchronize beech tree reproduction across vast distances in Europe, affecting ecosystem functions.
Published Alaska dinosaur tracks reveal a lush, wet environment
(via sciencedaily.com) Original source A large find of dinosaur tracks and fossilized plants and tree stumps in far northwestern Alaska provides new information about the climate and movement of animals near the time when they began traveling between the Asian and North American continents roughly 100 million years ago.
Published Giant sequoias are a rapidly growing feature of the UK landscape
(via sciencedaily.com) Original source Imported giant sequoia trees are well adapted to the UK, growing at rates close to their native ranges and capturing large amounts of carbon during their long lives, finds a new study.
Published History repeats as Coral Bay faces mass loss of coral and fish life
(via sciencedaily.com) Original source A perfect storm of environmental factors has seen a monumental loss of fish and coral life at a popular area of Ningaloo Reef in Western Australia's Gascoyne region -- however research into the event shows there is hope it will recover. In March 2022, during the annual coral spawning event, calm weather and limited tidal movement combined to trap the coral's eggs within Bills Bay, at the town of Coral Bay. This led to an excess of nutrients in the water which consumed more oxygen than usual -- causing massive numbers of fish and corals to die from asphyxiation.
Published A coral superhighway in the Indian Ocean
(via sciencedaily.com) Original source Despite being scattered across more than a million square kilometers, new research has revealed that remote coral reefs across the Seychelles are closely related. Using genetic analyses and oceanographic modelling, researchers demonstrated for the first time that a network of ocean currents scatter significant numbers of larvae between these distant islands, acting as a 'coral superhighway.'
Published Rainforest's next generation of trees threatened 30 years after logging
(via sciencedaily.com) Original source Rainforest seedlings are more likely to survive in natural forests than in places where logging has happened -- even if tree restoration projects have taken place, new research shows.
Published Study illuminates the protective role of fluorescence in neon-colored sea anemones
(via sciencedaily.com) Original source A team of researchers has uncovered a direct genetic link between fluorescence and color in sea anemones -- those soft and tentacled tide pool creatures often encountered by beachgoers.
Published Anemonefish are better taxonomists than humans
(via sciencedaily.com) Original source Scientists reveal new lineages of giant sea anemones in Japan and their surprising associations with anemonefish.
Published Halloween toy among plastics swallowed by sea turtles
(via sciencedaily.com) Original source A Halloween toy was among hundreds of plastic items found in the guts of dead sea turtles in the Mediterranean, a new study reveals.
Published Mapping the future's sweet spot for clean energy and biodiversity
(via sciencedaily.com) Original source A new study of Joshua trees, kit foxes and solar energy developments highlights the need to consider climate-induced range shifts for species as we expand clean energy.
