Pine Is Ten Times As Sensitive As Maple
Coniferous trees are widespread in Russia, especially in Siberia, where taiga extends over tens of millions of hectares. Cedars and pines grow also in the environs of cities and in city parks and suffer from human-induced changes in environment. Of course, coniferous trees can withstand a low-level... view more...

Tamed 11,400 years ago, figs were likely first domesticated crop
Archaeobotanists have found evidence that the dawn of agriculture may have come with the domestication of fig trees in the Near East some 11,400 years ago, roughly a thousand years before such staples as wheat, barley, and legumes were domesticated in the region. view more (2006-06-02)
The sap flow through trees.
The transport of water through trees Trees take up water from the soil by their root hairs and transport it through the vessels of the stem towards the leaves. At leaf level this water evaporates and comes into the atmosphere through little pores in the leaf epidermis, called stomates. This process is also known as transpiration. The water... view more...

Mechanical thinning increases fruit size, reduces labor
Hand thinning is a necessary but costly management practice in peach and organic apple production. Mechanical devices designed to help with thinning have been developed, but none has proven highly effective and capable of completely replacing hand thinning. view more (2009-02-18)
Subsidence: DNA profiling roots out offending trees
A new spinout company from the University of Leeds is laying claim to the most accurate identification of trees causing subsidence - using methods that could save the insurance industry millions in time and costs in disputed cases. Identi-Tree Ltd has been launched by the University's commercialisation partner, Techtran Group Ltd. Identi-Tree is... view more... (2004-04-26)
Early hominid first walked on two legs in the woods
Among the many surprises associated with the discovery of the oldest known, nearly complete skeleton of a hominid is the finding that this species took its first steps toward bipedalism not on the open, grassy savanna, as generations of scientists - going back to Charles Darwin - hypothesized, but in a wooded landscape. view more (2009-10-09)
A win-win: U-pick pumpkin farms recycle urban leaves
Americans love pumpkins. The growing popularity of rural fall festivals, grade school farm tours, and "u-pick" pumpkin farms has resulted in an increase in consumer demand for pumpkins throughout the country. view more (2008-12-29)
Iowa State professor's research shows Midwest forests losing diversity, complexity
Forests in the nation's Upper Midwest have changed greatly since the time of the early settlers. And more changes may be coming. view more (2007-10-17)
Soil nutrients shape tropical forests, large-scale study indicates
Tropical forests are among the most diverse plant communities on earth, and scientists have labored for decades to identify the ecological and evolutionary processes that created and maintain them. view more (2007-01-12)
Reviving American chestnuts may mitigate climate change
A Purdue University study shows that introducing a new hybrid of the American chestnut tree would not only bring back the all-but-extinct species, but also put a dent in the amount of carbon in the Earth's atmosphere. view more (2009-06-11)
Rhododendron expansion may increase the chance of landslides on Southern Appalachian slopes
Research by U.S. Forest Service Southern Research Station (SRS) scientists and partners suggests that the expansion of rosebay rhododendron (Rhododendron maximum) in Southern Appalachian mountain hollows may increase the likelihood of landslides during and after intense rain events. view more (2009-08-31)
Logging may hinder forest regeneration, increase fire risk
A new study done in the area burned in the catastrophic Biscuit Fire in Southwestern Oregon in 2002 found that allowing trees to naturally regenerate works about as well or better than logging and replanting, and that undisturbed areas may be at lower fire risk in the future. view more (2006-01-06)
Electrical circuit runs entirely off power in trees
You've heard about flower power. What about tree power? It turns out that it's there, in small but measurable quantities. There's enough power in trees for University of Washington researchers to run an electronic circuit. view more (2009-09-09)
Fires in far northern forests to have cooling, not warming, effect
Droughts and longer summers tied to global warming are causing more fires in the Earth's vast northernmost forests, a phenomenon that will spew a steadily increasing amount of carbon dioxide into the atmosphere. view more (2006-11-17)
Direct link established between tropical tree and insect diversity
Higher tree species diversity leads directly to higher diversity of leaf-eating insects. view more (2006-07-19)
Experiment suggests limitations to carbon dioxide 'tree banking'
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... view more...

Magnetic Leaves Reveal Bellingham's Most Polluted Byways
Tree leaves may be powerful tools for monitoring air quality and planning biking routes and walking paths, suggests a new study by scientists at Western Washington University in Bellingham. The research will be presented at this month's Annual Meeting of the Geological Society of America in Portland, Oregon. view more (2009-10-16)
Seed dispersal in mauritius -- dead as a dodo?

UC Scientists Determine That Ancient Maya Practiced Forest Conservation - 3,000 Years Ago
As published in the July issue of the "Journal of Archaeological Science," paleoethnobotanist David Lentz of the University of Cincinnati has concluded that not only did the Maya people practice forest management, but when they abandoned their forest conservation practices it was to the detriment of the entire Maya culture. view more (2009-07-23)
