A Better Way to Probe Peat

Sarah Witman, Freelance Writer

Research Spotlight— Florida scientists use ground-penetrating radar to image underground carbon stores in the Disney Wilderness Preserve. Millions of years before it can turn into coal, dead and decaying organic matter exists as a dark, spongy, carbon-rich material called peat. When layers of peat become.... more

Scientists Probe Water Inside Leaves via Satellite

Sarah Witman, Freelance Writer

Research Spotlight— Improving satellite-based studies of vegetation optical depth, a critical ecosystem indicator. Sensors on board satellites are able to detect a host of environmental metrics, from Arctic sea ice melt to the reproductive patterns of mule deer to logging and land clearing. One satellite-based.... more

Mossy Oaks Are Dripping with Organic Matter

Emily Underwood, Freelance Writer

Research Spotlight— Epiphyte-bearing trees leach carbon when it rains. The live oak forests of Savannah, Ga., are famous for their ghostly, gray-green curtains of Spanish moss. The moss belongs to a group of plants called epiphytes, which live in the branches and trunks of trees and get everything they.... more

Why Mountainous Upland Forests Emit So Much Methane

Emily Underwood, Freelance Writer

Research Spotlight— New research suggests that moist tree heartwood produces methane and emits the greenhouse gas to the atmosphere. Methane, one of the most potent greenhouse gases, has increased in the atmosphere by roughly 150% since the preindustrial era. Although much methane comes from wetlands.... more

Exploring the hydrological impacts of tree dieoffs in a semi-arid woodland

Editors' Highlight—   The death of piñon-juniper trees following the recent drought in the southwestern United States has received much attention. However, there are remarkably few detailed field-based measurements of the hydrologic impacts on mortality and this paper presents a well-designed experiment.... more

Searching for Organic Carbon in the Dry Valleys of Antarctica

Emily Underwood, Freelance Writer

Editors' Highlight— Researchers identify the first evidence of microbial respiration in desiccated Antarctic permafrost soils. Few organisms can survive in the upper reaches of the windswept McMurdo Dry Valleys of Antarctica. In the high, desiccated, “ultraxerous zone,” ice rarely if ever melts, and.... more

Sandy Beaches Are Hotbeds of Biochemical Activity

Emily Underwood, Freelance Writer

Research Spotlight— A new study explores the role of wet sand in coastal ecology. Most beachgoers enjoying the Sun and surf don’t think very much about the wet sand beneath their feet. But this soggy, sandy zone is of prime ecological importance. Nutrients and contaminants leach into the marine environment.... more

An advance in global photosynthesis modeling

Editor’s Highlight—  Recently, there has been some discussion over whether reflectance-based approaches versus solar induced chlorophyll fluorescence (SIF) can really yield good estimates of Gross Primary Productivity (GPP), with some authors suggesting SIF to be superior. This study indicates that.... more

Plumbing the Depths of the Marine Carbon Cycle

Sarah Witman, Freelance Writer

From Research Spotlights— Scientists measure dissolved black carbon in South China Sea water samples to better understand the carbon cycle in the oceans, which absorb roughly half of all carbon emitted into the atmosphere.  To fully understand how the oceans regulate carbon concentrations.... more

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
