  • Traffic noise reduces birds' response to alarm calls

    Pollution can take many forms–including noise. Excess noise in the environment from sources such as traffic can have negative effects on animals that rely on sound to communicate and get information about their surroundings. A new study from The Condor: Ornithological Applications shows that traffic noise makes birds less responsive to alarm calls that would otherwise alert…

  • What Satellites Can Tell Us About How Animals Will Fare in a Changing Climate

    From the Arctic to the Mojave Desert, terrestrial and marine habitats are rapidly changing. These changes impact animals that are adapted to specific ecological niches, sometimes displacing them or reducing their numbers. From their privileged vantage point, satellites are particularly well-suited to observe habitat transformation and help scientists forecast impacts on the distribution, abundance and…

  • Could Rudolph and friends help to slow down our warming climate?

    Reindeer may be best known for pulling Santa’s sleigh, but a new study suggests they may have a part to play in slowing down climate change too.A team of researchers, writing in the journal Environmental Research Letters, found that when reindeer reduce the height and abundance of shrubs on the Arctic tundra through grazing, the level…

  • High-Severity Wildfires Complicate Natural Regeneration for California Conifers

    A study spanning 10 national forests and 14 burned areas in California found that conifer seedlings were found in less than 60 percent of the study areas five to seven years after fire. Of the nearly 1,500 plots surveyed, 43 percent showed no natural conifer regeneration at all.

  • Rudolph's antlers inspire next generation of unbreakable materials

    The team looked at the antler structure at the 'nano-level', which is incredibly small, almost one thousandth of the thickness of a hair strand, and were able to identify the mechanisms at work, using state-of-the-art computer modelling and x-ray techniques.First author Paolino De Falco from QMUL's School of Engineering and Materials Science said: "The fibrils that make…

  • Studying the distant past in the Galapagos Islands

    The Galápagos Islands are home to a tremendous diversity of plants and animals found nowhere else in the world. But why this is, and when it all began, remains something of an open question. Now scientists may have at least one more piece of the puzzle. According to a new study out today in the journal Earth…

  • Chemicals of 'emerging concern' mapped in 3 Great Lakes

    For the first time, researchers at the University of Illinois at Chicago have mapped the location of thousands of tons of polyhalogenated carbazoles in the sediment of the Great Lakes and estimated their amount.

  • Scientists bear witness to birth of an ice cloud

    RICHLAND, Wash. – Scientists have witnessed the birth of atmospheric ice clouds, creating ice cloud crystals in the laboratory and then taking images of the process through a microscope, essentially documenting the very first steps of cloud formation.

  • Scientists: Strong evidence that human-caused climate change intensified 2015 heat waves

    Human-caused climate change very likely increased the severity of heat waves that plagued India, Pakistan, Europe, East Africa, East Asia, and Australia in 2015 and helped make it the warmest year on record, according to new research published today in a special edition of the Bulletin of the American Meteorological Society.  The fifth edition of…

  • Americans believe climate change connected to location and local weather

    A new study finds local weather may play an important role in Americans’ belief in climate change. The study, published on Monday, found that Americans’ belief that the earth is warming is related to the frequency of weather-related events they experience, suggesting that local changes in their climate influence their acceptance of this worldwide phenomenon. “One…
