Soil nutrition affects carbon sequestration in forests
On December 11, USDA Forest Service (FS) scientists from the FS Southern Research Station (SRS) unit in Research Triangle Park, NC, along with colleagues from Duke University, published two papers in The Proceedings of the National Academy of Science (PNAS) that provide a more precise understanding of how forests respond to increasing atmospheric... view more...

Spring into autumn to measure climate change
Volunteers have been so enthusiastic this year in recording the timing of natural events in springtime that an additional scheme is being run this autumn. Preliminary results from the huge volume of data gathered early in 1999 show that once again spring is arriving earlier in the UK. The dates when leaves first appear on the trees are ten days... view more... (1999-08-31)
University invention enlisted in battle against the brown-tailed moth
An environmentally friendly insect trap devised by researchers at the University of Southampton is the latest weapon in Portsmouth City Council's long-running battle to control infestations of the caterpillars of the brown-tailed moth. view more (1998-09-04)
Anti-biotech groups obstruct forest biotechnology
The potential of forest biotechnology to help address significant social and environmental issues is being "strangled at birth" by the rigid opposition of some groups and regulations that effectively preclude even the testing of genetically modified trees, scientists argue in a new report. view more (2009-07-01)
Laurel Wilt of Redbay and Sassafras: Will Avocados be Next?
Scientists with the USDA Forest Service Southern Research Station (SRS), Iowa State University, and the Florida Division of Forestry have provided the first description of a fungus responsible for the wilt of redbay trees along the coasts of South Carolina, Georgia, and Florida. view more (2008-04-03)
Revolutionary new findings about the history of trees and climate in Scandinavia
Scientists at Ume'å University in Sweden are putting forward an entirely new picture of climate change and the first immigration of trees following the last Ice Age. Research shows that 8,000-14,000 years ago the climate was considerably warmer than was previously thought. When it was at its warmest 9,000-10,000 years ago, the timberline was... view more...

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)
HOW TREES CHANGED THE WORLD
Before 380 million years (Ma) ago, the continents had only patches of mosses and algae with no tree cover. The effect of the evolution of trees (large vascular plants with deep, extensive roots) changed the world for ever, according to Dr Robert Berner (Yale University). He presents his findings at Earth Systems Processes, a multidisciplinary... view more... (2001-06-21)
Chickadee, nutchatch presence in conifers increases tree growth, says CU-Boulder study
Chickadees, nuthatches and warblers foraging their way through forests have been shown to spur the growth of pine trees in the West by as much as one-third, according to a new University of Colorado at Boulder study. view more (2007-08-02)
DOE JGI sequences, releases genome of symbiotic tree fungus
The DNA sequence of Laccaria bicolor, a fungus that forms a beneficial symbiosis with trees and inhabits one of the most ecologically and commercially important microbial niches in North American and Eurasian forests, has been determined by the U.S. Department of Energy DOE Joint Genome Institute (DOE JGI). view more (2006-07-25)
Poplar DNA code cracked — new possibilities for sustainable energy
Sustainable or renewable energy - in the form of bio-ethanol, for example - can be produced for us by trees. The influence trees have on our daily life is enormous. Forests cover 30% of the world's land area, accommodate two thirds of life on earth, and are responsible for 90% of the biomass on solid ground. view more (2006-09-15)
Entomologists play matchmakers for cerambycid beetles
Cerambycid beetles, also known as long-horned beetles, can cause severe damage to standing trees, logs and lumber. How then might they be promptly detected and their numbers swiftly controlled? view more (2008-08-06)
The kapok connection -- Study explains rainforest similarities
Celebrated in Buddhist temples and cultivated for its wood and cottony fibers, the kapok tree now is upsetting an idea that biologists have clung to for decades: the notion that African and South American rainforests are similar because the continents were connected 96 million years ago. view more (2007-06-18)
New study sheds light on long-term effects of logging after wildfire
A new study on the effects of timber harvest following wildfire shows that the potential for a recently burned forest to reburn can be high with or without logging. view more (2007-04-10)
Professor hopes to help high elevation pines grow
Thread-like fungi that grow in soils at high elevations may play an important role in restoring whitebark and limber pine forests in Canada. view more (2009-07-20)
Vine invasion? UWM ecologist looks at coexistence of trees and lianas
Among the hundreds of species of woody vines that University of Wisconsin-Milwaukee ecologist Stefan Schnitzer has encountered in the tropical forests of Panama, the largest has a stalk nearly 20 inches in circumference. view more (2008-08-06)
Exotic timber plantations found to use more than twice the water of native forests
Ecologists have discovered that timber plantations in Hawaii use more than twice the amount of water to grow as native forests use. view more (2009-09-16)
Seeing the forest and the trees
With human emissions of carbon dioxide on the rise, there is growing interest in maintaining the Earth's natural mechanisms that absorb and store carbon. view more (2005-10-24)
The bonsai effect: Wounded plants make jasmonates, inhibiting cell division, stunting growth
It is well known that plants growing under unfavourable conditions are generally smaller than those growing in stress-free conditions: indeed it is estimated that in the US, abiotic stress reduces the yield of agricultural crops by an average of 22%. view more (2008-11-12)
Emphasis on conifer forests places multiple species at risk
The traditional emphasis on dense, fast-growing, conifer-dominated forests in the Pacific Northwest raises questions about the health of dozens of animal species that depend on shrubs, herbs and broad-leaf trees, a new analysis by Oregon State University and the U.S. Geological Survey suggests. view more (2007-08-24)
