Our approach is predicated on the knowledge that precipitation δ 2 H and δ 18 O values (see Methods for definitions) co-vary along a regression line with a δ 2 H/δ 18 O slope of eight (this is the ...

Steve Nix is a member of the Society of American Foresters and a former forest resources analyst for the state of Alabama. Water mostly enters a tree through the roots by osmosis and any dissolved ...

Purdue Landscape Report: Water covers approximately 71% of Earth’s surface, yet only 3% of the 326 million cubic miles of water on the planet is suitable for growing crops, such as trees. It can be ...

A research team successfully developed a solar-powered artificial plant device and rapidly purified soil contaminated with radioactive cesium. This device, which mimics plant transpiration, can ...

The ability of trees to cool by transporting water from their roots to the leaves has been known for centuries. But as Stephen Ornes discovers, the principles of transpiration are also inspiring ...

As water travels through the xylem in the stem and leaf, it is being replaced by water taken up by the roots. Photosynthesis produces glucose in the green parts of plants, which are often leaves. This ...
