Climate change predicted to drive trees northward
The most extensive and detailed study to date of 130 North American tree species concludes that expected climate change this century could shift their ranges northward by hundreds of kilometers and shrink the ranges by more than half.   view more (2007-12-03)

Rogue trees get criminal treatment from scientists
Rogue trees are being ‘fingered’ by gene detectives using a well-known technique to catch criminals. Newcastle University scientists are using DNA fingerprinting to help insurers identify trees that are causing houses to subside. Often disputes can last for several years, as when two... view more (2002-08-27)

Mystery of fossilized trees is solved
An international research team has found evidence of the Earth's earliest forest trees, dating back 385 million years.   view more (2007-04-19)

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... view more (2003-04-29)

Spatial patterns in tropical forests can help to understand their high biodiversity
The high biodiversity in tropical forests has both fascinated and puzzled ecologists for more than half a century.   view more (2007-09-26)

Invasive species harms native hardwoods by killing soil fungus
An invasive weed that has spread across much of the U.S. harms native maples, ashes, and other hardwood trees by releasing chemicals harmful to a soil fungus the trees depend on for growth and survival.   view more (2006-04-26)

Tree-Killing Fungus Officially Named by Scientists
The USDA Forest Service Southern Research Station (SRS) today announced that an SRS scientist and other researchers have officially named the fungus responsible for killing redbay and other trees in the coastal plains of northeastern Florida, Georgia, and South Carolina.   view more (2008-07-01)

The autumn timetable is set - for a tree
How does a tree know it's autumn? Thanks to its genes, which are turned on and off in a pre-determined order. But in what order? Scientists at Ume'å Plant Science Center and the Royal Institute of Technology (KTH) in Stockholm have now brought to light the autumn "genetic timetable"... view more (2004-03-31)

Logging doubles threat to the Amazon, rivaling clear-cutting, study suggests
Human activities are degrading the Amazonian forest at twice the rate previously estimated, suggests a new study that adds the effects of logging to those of clear-cutting.   view more (2005-10-21)

Past droughts geographically widespread in the West, according to tree-ring data
When it's dry, it's dry all over, according to a new analysis of more than 400 years of annual streamflow in the Upper Colorado and Salt and Verde river basins.   view more (2005-08-19)

Researchers discover trees in Amazon much older than assumed, raising questions on global climate impact of region
Trees in the Amazon tropical forests are old. Really old, in fact, which comes as a surprise to a team of American and Brazilian researchers studying tree growth in the world's largest tropical region.   view more (2005-12-14)

Ancient Oak Trees Help Reduce Global Warming, MU Study Finds
The battle to reduce carbon emissions is at the heart of many eco-friendly efforts, and researchers from the University of Missouri have discovered that nature has been lending a hand. Researchers at the Missouri Tree Ring Laboratory in the Department of Forestry discovered that trees submerged in... view more (2008-06-30)

New study links Western wildfires to Atlantic Ocean surface temperatures
Western U.S. wildfires are likely to increase in the coming decades, according to a new tree-ring study led by the University of Comahue in Argentina and involving the University of Colorado at Boulder that links episodic fire outbreaks in the past five centuries with periods of warming sea surface... view more (2006-12-27)

Brown-led study rearranges some branches on animal tree of life
A study led by Brown University biologist Casey Dunn uses new genomics tools to answer old questions about animal evolution. The study is the most comprehensive animal phylogenomic research project to date, involving 40 million base pairs of new DNA data taken from 29 animal species.   view more (2008-03-06)

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)

The Influence Of Disturbance On Tropical Rainforest Biodiversity: End Of A Controversy In Sight
The many species which make up tropical rain forest tree communities show widely differing reactions to environmental factors. This is particularly so with regard to light. Pioneer species, highly heliophile (light-loving or shade-intolerant), establish themselves by taking advantage of canopy... view more (2001-11-23)

First 'rule' of evolution suggests that life is destined to become more complex
In a study published in the Proceedings of the National Academy of Sciences researchers have found evidence which suggests that evolution drives animals to become increasingly more complex.   view more (2008-03-18)

Traditional Christmas snack under threat
An international group of scientists is warning that the traditional Christmas snack of Brazil nuts could be under threat if intensive harvesting practices continue in persistently exploited areas. Writing in this week's edition of the international journal Science (19 December 2003) the main... view more (2003-12-16)

Intensive youth soccer participation leads to growth deformations
In this study, 550 Belgian young soccer players were medically examined in different soccer teams at different competitive levels. The observed growth deformations in this study are situated at the knee joint, were an non-symmetrical growth was found. This non-symmetrical growth leads to the... view more (2002-06-11)

Building a better virtual world, one tree (or millions) at a time
When Stanford computer scientist Vladlen Koltun decided to build a better virtual world, he began with 3-D trees-millions of them. Now he wants to give them away.   view more (2008-01-09)

Big and fast growing infants at greater risk of later obesity
Large infants, and those who grow rapidly during the first two years of life, are at increased risk of obesity in childhood and adulthood, a study published online by the BMJ today (14 October 2005) has found.   view more (2005-10-14)

Unexpected finding: Some dinosaurs grew slower in hard times
Palaeontologists from the University of Bonn report on an intriguing diagnosis in the 16 December issue of the journal Science. A dinosaur which they have examined was apparently able to vary the speed of its growth according the conditions obtaining in its environment.   view more (2005-12-16)

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)

Presence of wolves allows aspen recovery in Yellowstone
