Mushrooms Could Provide a Record of Grassland History

Alexandra Branscombe, Freelance Writer

From Eos.org: Research Spotlights— Scientists measured carbon isotopes in certain types of fungi to assess whether the organisms can track how climate change is affecting grasses.  Since the Industrial Revolution, concentrations of carbon dioxide in the atmosphere have rapidly increased. How does this.... more

As Winters Get Warmer, Sugar Maples May Absorb Less Silicon

Sarah Stanley, Freelance Writer

From Eos.org: Research Spotlights— Rising temperatures that reduce snow cover leave soils vulnerable to frost, reducing silicon uptake by trees, with potential effects on downstream ecosystems.  Scientists predict that rising winter temperatures will reduce snow cover in mountainous and temperate forests..... more

Mysterious “Fairy Circles” Continue to Enchant Scientists

Sarah Witman, Freelance Writer

From Eos.org: Research Spotlights— Researchers revisit an old theory about the ethereal patterns of vegetation that form in some arid landscapes.  In just a couple places on Earth, namely, the scrubby deserts of Australia and Namibia, mysterious natural formations known as “fairy circles” dot the dry.... more

Arctic Permafrost Thaw Would Amplify Climate Change

Sarah Witman, Freelance Writer

From Eos.org: Research Spotlights—An international team probed Arctic permafrost samples to better understand the carbon feedback loop that could be set off by future thawing. A massive store of carbon—relics of long-dead plants and other living things—is preserved within the ancient permafrost of the.... more

Modeling Permafrost’s Role in the Global Carbon Cycle

Sarah Witman, Freelance Writer

From Eos.org: Research Spotlights—A team of international scientists surveyed an array of Earth ecosystem models, recommending several ways to reduce uncertainties. About half of the carbon that exists beneath Earth’s surface is stored within regions of permanently frozen ground, called permafrost..... more

How Climate Change Affects the Flow of Carbon from Land to Sea

From Eos.org: Research Spotlights—Changes in precipitation and runoff in New England may be driving more dissolved organic carbon into the Gulf of Maine.  The flow of dissolved organic carbon (DOC) from land to sea typically accounts for a small fraction of an ecosystem’s carbon budget compared with.... more

Fighting Fire With Satellite Data

Sarah Witman, Freelance Writer

From Eos.org: Research Spotlights As climate change worsens wildfire impact, scientists use satellites to study climate-fire interactions. Smokey Bear, the cuddly mascot of the U.S. Forest Service, has spent the past 70 years warning the American public against playing with matches. But while human.... more

Earth’s Ground Heat Flux Should Not Be Overlooked

Emily Underwood, Freelance Writer

From Eos.org: Research Spotlights—Scientists compare models of how much heat Earth’s surface gives off and absorbs from the atmosphere. One of the trickiest processes to represent accurately in global climate models is how Earth gives off and absorbs heat. This phenomenon is called ground heat flux.... more
