Forecasting Arctic soil temperatures under climate change

Editor’s Highlight—   This study expands our understanding of air temperature-soil temperature-nutrient mobilization in an Arctic environment under climate change. The authors ran forecast experiments for the Spruce and Peatland Responses Under Climatic and Environmental Change (SPRUCE) experimental.... more

Coastal Wetlands Effectively Sequester “Blue Carbon”

Sarah Witman, Freelance Writer

From Eos.org: Research Spotlights— Mangrove forests, salt marshes, seagrass beds, and the like are carbon storage treasure troves. Over the past 150 years, as greenhouse gas emissions from fossil fuel combustion and other human activities have steadily increased, Earth’s forests, oceans, and soil have.... more

Bacteria found near abandoned mines could shed light on early Earth

Blog— Acidified water draining from abandoned mines, studied primarily as a modern environmental hazard, may offer insight into the oxygenation of Earth’s early atmosphere and development of life on other planets, according to a new study. Scientists studying abandoned coal mines in Kentucky found.... more

The Future Hangs in the (Carbon) Balance

Jenny Lunn, Contributing Writer

From Eos.org: Research Spotlights— A new study suggests that Canada’s boreal forests could absorb more carbon than they release as climate change progresses.  What comes to mind if you’re asked to think of the natural landscapes of Canada? Chances are you will picture forest, endless forest. A wilderness.... more

Antarctic Microbes Shape Nutrient Content of Snowmelt

Sarah Stanley, Freelance Writer

From Eos.org: Research Spotlights— As temperatures continue to rise, snow-dwelling microbes could accelerate melting and influence downstream ecosystems.  Snowmelt on the Antarctic Peninsula has been increasing for decades, due to rising temperatures, and it shows no signs of stopping. As the snow.... more

Variations in atmospheric methane emissions from subtropical lakes

Editor’s Highlight—   This paper demonstrates how multiple methods of inferring methane fluxes from a lake could be used to reliably constrain and map the high spatial and temporal variation in methane fluxes in eutrophic lakes. The authors used a three-year dataset based on high resolution measurements.... more

Investigating the drivers of changes in plant leaf carbon isotope ratio

Editor’s Highlight—   Leaf carbon isotope ratio (δ13C) is an important plant trait for understanding plant physiology and ecology. It is also a useful tool for plant classification and paleo-environmental reconstruction. This study examines how genetic and morphological features, as well as environmental.... more

Tracking Nitrogen in Arctic Plants

Elizabeth Jacobsen, Staff Writer

From Eos.org: Research Spotlights— Prevailing nutrient uptake models do not fit Arctic plants. Scientists test a new option that overcomes older models’ shortcomings.  The Arctic is warming more than any other region on Earth, and this creates feedback loops that are notoriously difficult to predict..... more
