Diversity of trees in Ecuador's Amazon rainforest defies simple explanation
Trees in a hyper-diverse tropical rainforest interact with each other and their environment to create and maintain diversity, researchers report in the Oct. 24 issue of the journal Science. view more (2008-10-24)
Evolution of new species slows down as number of competitors increases
The rate at which new species are formed in a group of closely related animals decreases as the total number of different species in that group goes up, according to new research published in PLoS Biology. view more (2008-03-25)
Incentives for carbon sequestration may not protect species
Paying rural landowners in Oregon's Willamette Basin to protect at-risk animals won't necessarily mean that their newly conserved trees and plants will absorb more carbon from the atmosphere and vice versa, a new study has found. view more (2008-07-08)
To climate-change worries, add one more: extended mercury threat
Mercury pollution has already spurred public health officials to advise eating less fish, but it could become a more pressing concern in a warmer world. view more (2009-01-08)
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)
Study explores effects of herbicide drift on white oak
Herbicide drift, which occurs when pesticides "drift" from the targeted application area to a nearby non-targeted area, is a particular concern in Midwestern regions of the United States. view more (2009-03-26)
Study of Tropical Forests Worldwide Reveals that Nature Encourages Diversity
An analysis of seven tropical forests around the world has found that nature encourages diversity by selecting for less common trees as the trees mature. view more (2006-01-27)
Long-term study of orchard ground cover management systems
Orchard floor and groundcover management is important to fruit growers, affecting the efficiency of orchard operations, fruit tree performance, and soil quality. view more (2009-02-27)
Fungal factories may save hemlock forests
Reaching into a box glowing with fluorescent light, Stacie Grassano pulls out a tube. "This is a great one," she says, holding the clear plastic up to her face. Inside, a tree branch is speckled with white fluff. "It's growing really well," she says, handing it to Scott Costa. view more (2007-01-29)
Without disturbances in nature the world's forests will be impoverished
The forests of the world are not the stable and unchanging ecosystems they have been assumed to be. Without the occurrence of wide-spread disturbances in nature, such as forest fires, icing, or volcanic activity, forests will eventually be impoverished, owing to a lack of phosphorous. This is shown in a study reported in this week's issue of the... view more... (2004-06-21)
Fighting pollution the poplar way: Trees to clean up Indiana site
Purdue University researchers are collaborating with Chrysler LLC in a project to use poplar trees to eliminate pollutants from a contaminated site in north-central Indiana. view more (2008-01-11)
Northern forests less effective than tropical forests in reducing global warming
Forests in the United States and other northern mid- and upper-latitude regions are playing a smaller role in offsetting global warming than previously thought, according to a study appearing in this week's issue of Science. view more (2007-06-25)
Forest fires may lead to cooling of northern climate
Countering hypotheses that forest fires in Alaska, Canada and Siberia warm the climate, scientists at UC Irvine have discovered that cooling may occur in areas where charred trees expose more snow, which reflects sunlight into space. view more (2006-11-17)
Insurgental Biological Warfare Against Gipsy Moth
Specialists of the Institute of Taxonomy and Ecology of Animals (Siberian Branch, Russian Academy of Sciences) investigate peculiarities of struggle against Asian populations of Gipsy moth - one of the most widespread and economically significant forest pests. The methods applied in the North America and Europe do not work with Asian populations... view more... (2005-04-29)
Why are autumn leaves red in America and yellow in Europe?
Walking outdoors in the fall, the splendidly colorful leaves adorning the trees are a delight to the eye. In Europe these autumn leaves are mostly yellow, while the United States and East Asia boast lustrous red foliage. view more (2009-08-13)
Slow but sure — Burned forest lands regenerate naturally
A new study of forest lands that burned in the 1990s in northern California and southwestern Oregon has concluded there is a "fair to excellent" chance that an adequate level of conifers will regenerate naturally, in sites that had no manual planting or other forest management. view more (2007-04-04)
Saving Trees by Stemming Beetles
International efforts to protect forests have been given a boost by a unique information initiative headed by a University of Ulster scientist. Leading a four-year project compiling research by 100 European scientists, Coleraine-based researcher Dr Keith Day has co-edited a landmark publication providing essential information aimed at saving trees... view more...

Gardens Will Be Planted By Computer Order
The program developed by Russian specialists of the North-Caucasian Scientific Research Institute of Gardening and Viticulture (Russian Agricultural Academy, Krasnodar) allows to select cultures, horticultural crops and other agricultural specimen the most profitable for a given locality. The development was supported by the Russian Foundation for... view more... (2004-10-22)
New Sequencing Technique Could Boost Pine Beetle Fight, Improve Cancer Research
UBC researchers have helped developed a cheaper, faster way to compile draft genome sequences that could advance the fight against mountain pine beetle (MPB) infestation and improve cancer research. view more (2009-09-16)
Managing Douglas-fir forests for diversity
Creating diverse forests for multiple uses is important to natural resource managers and landowners. view more (2009-05-11)
