Central Africa's tropical Congo Basin was arid, treeless in Late Jurassic
The Congo Basin - with its massive, lush tropical rain forest - was far different 150 million to 200 million years ago. At that time Africa and South America were part of the single continent Gondwana. view more (2009-11-11)
Well-traveled wasps provide hope for vanishing species
They may only be 1.5mm in size, but the tiny wasps that pollinate fig trees can travel over 160km in less than 48 hours, according to research from scientists at the University of Leeds. The fig wasps are transporting pollen ten times further than previously recorded for any insect. view more (2009-11-10)
Ants are friendly to some trees, but not others
Tree-dwelling ants generally live in harmony with their arboreal hosts. But new research suggests that when they run out of space in their trees of choice, the ants can get destructive to neighboring trees. view more (2009-11-09)

Sun or shade: Pecan leaves' photosynthetic light response evaluated
Pecan, the most valuable nut tree native to North America, is native from northern Illinois and southeastern Iowa to the Gulf Coast of the United States, where it grows abundantly along the Mississippi River, the rivers of central and eastern Oklahoma, and Texas. view more (2009-11-04)
Pecan trees benefit from thinning technique
Pecan trees, like many fruit trees, have a tendency to bear fruit in cycles, producing a large crop in one or two years, followed by one or two years with little or no crop. view more (2009-11-04)
Study of alternate bearing presents recommendations for citrus growers
Alternate bearing (also called biennial or uneven bearing) is the tendency of fruit trees to produce a heavy crop one year (called "on-crop") followed by a light crop or no crop the following "off-crop" year. view more (2009-11-03)
Trees facilitate wildfires as a way to protect their habitat
Fire is often thought of something that trees should be protected from, but a new study suggests that some trees may themselves contribute to the likelihood of wildfires in order to promote their own abundance at the expense of their competitors. view more (2009-10-29)
Spider web glue spins society toward new biobased adhesives
With would-be goblins and ghosts set to drape those huge fake spider webs over doorways and trees for Halloween, scientists in Wyoming are reporting on a long-standing mystery about real spider webs: It is the secret of spider web glue. view more (2009-10-22)
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)
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)
Canker disease in eucalyptus in the Basque Country
The first experiences with exotic species in the Basque Country, and alternative to Pinus radiata, were undertaken in 1957, concretely in Laukiz, Lezama and Alonsotegui (Muro, 1975) where the eucalyptus, amongst other forest species, was introduced. view more (2009-09-29)
Tennessee foresters helping to return chestnuts to American forests
The American chestnut was a dominant species in eastern U.S.'s forests before a blight wiped it out in the early 1900s. Today it's being returned to the landscape thanks in part to work by a University of Tennessee Forestry alumna and the UT Tree Improvement Program (UT TIP). view more (2009-09-24)
'Green Clean:' Researchers Determining Natural Ways To Clean Contaminated Soil
Researchers at North Carolina State University are working to demonstrate that trees can be used to degrade or capture fuels that leak into soil and ground water. Through a process called phytoremediation - literally a "green" technology - plants and trees remove pollutants from the environment or render them harmless. view more (2009-09-18)
Exotic timber plantations found to use more than twice the water of native forests

Northwestern United States could face more tamarisk invasion by century's end
If the future warming trends that scientists have projected are realized, one of the country's most aggressive exotic plants will have the potential to invade more U.S. land area, according to a new study published in the current issue of the journal Invasive Plant Science and Management. view more (2009-09-16)
Dandelion rubber
Most natural rubber comes from rubber trees in Southeast Asia, but this source is now under threat from a fungus. Researchers have optimized the Russian dandelion to make it suitable for large-scale rubber production. view more (2009-09-11)
