Forests have a limited capacity to soak up atmospheric carbon dioxide, according to a new study from Northern Arizona University. The study, available online in the journal New Phytologist, aimed to explore how rising atmospheric carbon dioxide could alter the carbon and nitrogen content of ecosystems. By performing tests on subtropical woodland plots over an 11-year period, the researchers found that ecosystem carbon uptake was not significantly increased by the high CO2...

Organic matter is important for soil health and crop productivity. While an indicator of soil quality, a lot of organic matter is in extremely stable forms, and the nutrients in such forms are difficult for plants to use. The active, labile fraction, however, is a modest but important part of the organic matter. "The labile fraction is small — usually less than 20 or even 10 percent, depending on how you define it," explains Steve Culman, lead author of a study published online Feb....

Berkeley Lab research could lead to a better understanding of the Arctic ecosystem´s impact on the planet's climate What does pulling a radar-equipped sled across the Arctic tundra have to do with improving our understanding of climate change? It´s part of a new way to explore the little-known world of permafrost soils, which store almost as much carbon as the rest of the world´s soils and about twice as much as is in the atmosphere. The new approach combines several...

Forest Ecosystems Impacted By Climate Change
2012-11-29 12:04:30

April Flowers for redOrbit.com - Your Universe Online Off the southern coast of California, the fog rolls in over Santa Cruz Island coating the needles of the Bishop pines with moisture. Water drops form on the needles and roll down to fall to the forest floor, happening over and over on every needle of every tree. The forest ecosystem depends on this fog drip to stay alive. Bishop pines are thought to have proliferated all along the West Coast of the US and Mexico thousands of years...

In a surprising finding, North Carolina State University researchers have shown that certain underground organisms thought to promote chemical interactions that make the soil a carbon sink actually play a more complex, dual role when atmospheric carbon levels rise. In a paper published in the Aug. 31 edition of Science, North Carolina State University researchers show that important and common soil microscopic organisms, arbuscular mycorrhizal fungi (AMF), play a role in sequestering...

Rising Carbon Dioxide In Atmosphere Speeds Carbon Loss From Forest Soils
2012-07-10 15:29:04

Underappreciated player in carbon storage should be included in global change models, researcher says Elevated levels of atmospheric carbon dioxide accelerate carbon cycling and soil carbon loss in forests, new research led by an Indiana University biologist has found. The new evidence supports an emerging view that although forests remove a substantial amount of carbon dioxide from the atmosphere, much of the carbon is being stored in living woody biomass rather than as dead organic...

It's All About The Dirt

[ Watch the Video ] A new study by researchers at BYU, Duke and the USDA finds that soil plays an important role in controlling the planet´s atmospheric future. The researchers set out to find how intact ecosystems are responding to increased levels of carbon dioxide in the atmosphere. The earth´s current atmospheric carbon dioxide is 390 parts per million, up from 260 parts per million at the start of the industrial revolution, and will likely rise to more than 500 parts per...

Predator-Created Domino Effect Leads To Ecosystem Changes
2012-06-17 05:42:51

Creatures that are feeling the pressure from the presence of predators are known to alter their diets, thus having a noteworthy impact on their habitats, claims new research published in the journal Science. According to the National Science Foundation (NSF), researchers from Yale University and the Hebrew University of Jerusalem teamed up to study changes in the types of plant life consumed by grasshoppers under different circumstances. Ordinarily, grasshoppers eat nitrogen-rich grass,...

Measuring CO2 To Help Fight Global Warming
2012-05-15 06:46:02

University of Utah and Harvard scientists develop way to enforce future greenhouse gas treaty If the world's nations ever sign a treaty to limit emissions of climate-warming carbon dioxide gas, there may be a way to help verify compliance: a new method developed by scientists from the University of Utah and Harvard. Using measurements from only three carbon-dioxide (CO2) monitoring stations in the Salt Lake Valley, the method could reliably detect changes in CO2 emissions of 15 percent...

Why did the atmosphere contain so little carbon dioxide (CO2) during the last Ice Age 20,000 years ago? Why did it rise when the Earth's climate became warmer? Processes in the ocean are responsible for this, says a new study based on newly developed isotope measurements. This study has now been published in the scientific journal "Science" by scientists from the Universities of Bern and Grenoble and the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association....
