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)
Discovery May Speed Tree Breeding, Biotechnology
Researchers have discovered the genetic controls that cause trees to stop growing and go dormant in the fall, as well as the mechanism that causes them to begin flowering and produce seeds — a major step forward in understanding the basic genetics of tree growth. view more (2006-06-01)
A computer simulation tool that predicts the influence of forest clearings on soil fertility
The process of clearing consists of cutting down trees in such a way that those remaining have more resources and can grow more. The question was if too many had been cut down, with the concomitant removal of nutrients, and the manner, therefore, in which this process might affect long-term soil fertility. view more (2004-09-08)
Conserving historic apple trees
The apple trees of yesteryear are slowly disappearing. Many apple varieties common in the United States a century ago can no longer be found in today's orchards and nurseries. view more (2009-11-05)
Old growth forests are valuable carbon sinks
Contrary to 40 years of conventional wisdom, a new analysis to be published Friday in the journal Nature suggests that old growth forests are usually "carbon sinks" - they continue to absorb carbon dioxide from the atmosphere and mitigate climate change for centuries. view more (2008-09-11)
Ice storms devastating to pecan orchards
Ice storms and other severe weather can have devastating impacts on agricultural crops, including perennial tree crops. view more (2009-03-25)
Scattered nature of Wisconsin's woodlands could complicate forests' response to climate change
If a warmer Wisconsin climate causes some northern tree species to disappear in the future, it's easy to imagine that southern species will just expand their range northward as soon as the conditions suit them. view more (2008-07-16)
Monkeys don't go for easy pickings
Animals' natural foraging decisions give an insight into their cognitive abilities, and primates do not automatically choose the easy option. Instead, they appear to decide where to feed based on the quality of the resources available and the effect on their social group, rather than simply selecting the nearest food available. view more (2007-07-18)
The National Radiological Protection Board advises holiday makers against overexposure to high sunlight
The incidence of skin cancer in the UK has significantly increased in recent years. There are now over 40,000 new cases and nearly 2,000 deaths from skin cancer in the UK each year. Much of this increase has been attributed to overexposure to sunlight not only when abroad but also sunbathing at home. In one recent study in Scotland, a third of... view more... (2003-05-27)
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)
New findings indicate HIV/AIDS pandemic began around 1900, earlier than previously thought
New research indicates that the most pervasive global strain of HIV began spreading among humans between 1884 and 1924, not during the 1930s, as previously reported. view more (2008-10-02)
Fire On French Riviera
A month after an earlier blaze was quelled, fire returned to the forested hills above the French Riviera this week. Since last Sunday many hundreds of hectares of woodland have been incinerated. The damage done is seen from space in this image acquired by ESA's Proba satellite this week. Taken on Wednesday 3 September, this true-colour picture... view more... (2003-09-04)
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 freshwater aquatic systems store carbon for... view more... (2008-06-30)
Beetle dung helps forests recover from fire
Armed with a pair of tweezers and a handful of beetle droppings, University of Alberta forestry graduate Tyler Cobb has discovered why the bug-sized dung is so important to areas ravaged by fire. view more (2007-12-04)
Decreasing deer damage
The nontimber forest products industry has been growing rapidly since the mid-1980s, contributing billions of dollars to the U.S. economy annually. view more (2009-05-04)
Ancient birds flew on all-fours
The earliest known ancestor of modern-day birds took to the skies by gliding from trees using primitive feathered wings on their arms and legs, according to new research by a University of Calgary paleontologist. view more (2006-09-22)
New theory -- universal intelligence on animals and plants
Here it is proposed that life in all its variety is full of sensation and creates a complicated web of interaction with its surroundings. Mammals, birds and even fish mourn for a lost love. Single-celled organisms carry out tasks that are surprisingly complicated. We can demonstrate sensitivity in microscopic organisms, while plants emerge as... view more... (1999-03-25)
Landscapes and human behavior
On Arizona State University's (ASU) Polytechnic campus, graduate student families in the cluster of six houses abutting lush lawns and ornamental bushes spend time together talking while their kids play outside. view more (2006-08-10)
More carbon dioxide may help some trees weather ice storms
The increased levels of carbon dioxide in the atmosphere predicted for later this century may reduce the damage that future ice storms will cause to commercially important loblolly pine trees, according to a new study. view more (2006-08-16)
Urban Trees Enhance Water Infiltration
Global land use patterns and increasing pressures on water resources demand creative urban stormwater management. view more (2008-11-20)
