A chilling solution -- Measuring below-ground carbon without destroying trees
12-05-2006 · EurekAlert!USDA Forest Service (FS) researchers have provided the first proof of concept for a method that allows scientists to study below-ground carbon allocation in trees without destroying them. In the latest issue of the journal Plant, Cell & Environment, Kurt Johnsen and fellow researchers at the FS Southern Research Station unit in Research Triangle Park, NC, describe a reversible, non-destructive chilling method that stops the movement of carbon into root systems.

- Storing carbon dioxide below ground analyzed
02-07-2007 · Massachusetts Institute of Technology (MIT)
A new analysis led by an MIT scientist describes a mechanism for capturing carbon dioxide emissions from a power plant and injecting the gas into the ground, where it would be trapped naturally as tiny bubbles and safely stored in briny porous rock.

- Experiment suggests limitations to carbon dioxide 'tree banking'
08-07-2007 · EurekAlert!
While 10 years of bathing North Carolina pine tree stands with extra carbon dioxide did allow the trees to grow more tissue, only those pines receiving the most water and nutrients were able to store significant amounts of carbon that could offset the effects of global warming, scientists told a national meeting of the Ecological Society of America.

- End of deforestation in view? Experts advance new way to size up global forest resources
11-13-2006 · EurekAlert!
An increasing number of countries and regions are transitioning from deforestation to afforestation, raising hopes for a turning point for the world as a whole, according to researchers advancing a more sophisticated approach to measuring forest cover. The novel approach looks beyond simply how much of a nation's area is covered by trees and considers the volume of timber, biomass and captured carbon within the area.

- Planting carbon deep in the earth -- rather than the greenhouse
11-26-2007 · EurekAlert!
University of Leeds research shows how storing carbon dioxide deep below the earth's surface could be a safe, long-term solution to one of the planet's major contributors to climate change.

- Fatal attraction: Elephants and marula fruit
02-14-2007 · EurekAlert!
Being female can be a risky business, especially if you are a Marula tree in Africa receiving the attention of elephants. Research published in African Journal of Ecology shows that the female Marula suffers a higher risk than the male tree of being destroyed and perhaps killed by elephants. "There is a conflict of interest experienced by female trees when the disperser also has the potential to seriously damage or kill the tree."

- Human ancestors learnt to walk upright in the trees, say experts
06-01-2007 · EurekAlert!
Scientists at the University of Liverpool have found that humans' ability to walk upright developed from ancestors foraging for food in forest tree tops and not from walking on all fours on open land.

- Colorado River streamflow history reveals megadrought before 1490
05-17-2007 · EurekAlert!
An epic drought during the mid-1100s dwarfs any drought previously documented for a region that includes areas of Arizona, Colorado, New Mexico, Utah and Wyoming. The six-decade-long drought was marked by the absence of very wet years and a 25-year period when Colorado River flow averaged 15 percent below normal. The new tree-ring-based reconstruction documents the year-by-year natural variability of streamflows in the upper Colorado River basin back to A. D. 762.
