North American Wild Rice Faces Sulfide Toxicity

Jenny Lunn, Contributing Writer

From Research Spotlights— Researchers have developed a model to inform the regulation of sulfate levels, in freshwater environments, that are threatening the iconic plant.  Wild rice (Zizania palustris) is a native North American marsh grass, which grows in shallow aquatic environments such.... more

Potential climate warming impacts of carbon rich soils in Siberia

Editor’s Highlight—   The carbon rich soils of Siberia could potentially cause significant climate warming impacts. This study provides new knowledge on carbon fluxes (uptake/release) in two ecosystems located on thawing permafrost soils in a far northern region undergoing an extremely rapid rate of.... more

Observations on the role of microbes in nontronite mineralization

Editor’s Highlight—   This manuscript presents textural, microbiological and geochemical characteristics of hydrothermal nontronite deposits from a recently discovered vent field at the South Mid-Atlantic Ridge. The authors aim to resolve whether microorganisms play a role in nontronite mineralization.... more

Integrating the activities of soil microorganisms into mathematical models

Editor’s Highlight—   This paper examines the ramifications of incorporating specific microbial controls on decomposition processes. At the core of this work is the integration of two previous models, DAMM and MCNiP, combining the more realistic effects of temperature and moisture on the kinetics of.... more

Following Carbon in an Age of Fire

Elizabeth Thompson, Freelance Writer

From Research Spotlights— As fires become more prevalent in California, researchers work to create a profile of the charred carbon left behind. The 2012 wildfire season in the United States was record-breaking, burning an area equivalent to the entire state of Maryland, Washington, D. C.,.... more

The River Basin’s Tale: Carbon Transport Along the Thames

Sarah Witman, Freelance Writer

From Research Spotlights— Study finds that population growth during urbanization, and World War II–era plowing, fed additional carbon into the Thames River Basin. More than a decade after writing The Jungle Book, British novelist Rudyard Kipling penned a poem in honor of the major waterway.... more

Microbes May Thrive in Subsea Permafrost Long After Flooding

Sarah Stanley, Freelance Writer

From Research Spotlights— Two cores from the East Siberian Arctic Shelf reveal how microbial communities develop over thousands of years as submarine permafrost slowly thaws.  Permanently frozen soil and rock known as permafrost is a familiar feature in cold climates on land. However, it also.... more

Simulation of future forest growth in New England over next 90 years

Editor’s Highlight— This manuscript analyzes the tradeoffs among New England’s forest types and climate regions in terms of the changing net primary productivity due to climate change. While the simulation results demonstrate a result that we already know, in the existence of a tradeoff of longer growing.... more

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 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
