Diverse tropical forests defy metabolic ecology models
As global change accelerates, quantifying the role of forests in the carbon cycle becomes ever more urgent. Modelers seek simple predictors of forest biomass and carbon flux. view more (2006-04-24)
Temperate Forests Could Worsen Global Warming
Growing a forest might sound like a good idea to combat global warming, since trees draw carbon dioxide from the air and release cool water from their leaves. view more (2005-12-07)
"Live fast, die young" applies to forests, too.
Forests provide humans with economically important and often irreplaceable products and services, and affect global climate by acting as sources and sinks of heat-trapping carbon dioxide. Yet the possible responses of forests to ongoing environmental changes are poorly understood. In the most recent issue of Ecology Letters, Stephenson and van... view more... (2005-04-19)
Errors in the measurement of global warming corrected
The effect of the sun's heat on weather balloons largely accounts for a data discrepancy that has long contributed to a dispute over the existence of global warming, according to a report by scientists at Yale University and the National Oceanic and Atmospheric Administration (NOAA). view more (2005-08-12)
Tropical forests — Earth's air conditioner
Planting and protecting trees—which trap and absorb carbon dioxide as they grow—can help to remove carbon dioxide from the atmosphere. view more (2007-04-10)
Amber reveals ecology of 30 million year old spiders
Scientists at The University of Manchester and the Manchester Metropolitan University have carried out the first comparative scientific study of ancient spiders trapped in amber more than 30 millions years ago. view more (2006-03-01)
Fires in far northern forests to have cooling, not warming, effect
Droughts and longer summers tied to global warming are causing more fires in the Earth's vast northernmost forests, a phenomenon that will spew a steadily increasing amount of carbon dioxide into the atmosphere. view more (2006-11-17)
Deep-rooted plants have much greater impact on climate than experts thought
Trees, particularly those with deep roots, contribute to the Earth's climate much more than scientists thought, according to a new study by biologists and climatologists from the University of California, Berkeley. view more (2006-01-12)
Forests damaged by Katrina may contribute to global warming
Researchers led by biologist Jeffrey Chambers of Tulane University have determined that the losses inflicted by Hurricane Katrina on Gulf Coast forest trees are enough to cancel out a year's worth of new tree biomass (trunks, branches and foliage) growth in other parts of the country. view more (2007-11-16)
Winning by a neck — Giraffes avoid competing with shorter browsers
The giraffe's elongated neck has long been used in textbooks as an illustration of evolution by natural selection, but this common example has received very little experimental attention. view more (2006-12-26)
Underdogs in the understory: Study suggests nature favors rarer trees
A study of seven tropical forests around the world has revealed that nature encourages biodiversity by favoring the growth of less common trees. view more (2006-01-30)
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)
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)
Found — the apple gene for red
CSIRO researchers have located the gene that controls the colour of apples - a discovery that may lead to bright new apple varieties. view more (2006-12-04)
Shift of Weather Patterns Necessitates Rethinking of Reforestation Methods
Forest landowners can greatly increase the survival rate of pine tree seedlings by changing when and how they plant, according to research conducted here. view more (2005-05-27)
How trees manage water in arid environments
The summer of 2006 was the second warmest in the continental United States since records began in 1895, according to the National Climatic Data Center. Moderate to extreme drought conditions were evident in about 40 percent of the country. view more (2007-01-05)
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)
World's oldest living tree discovered in Sweden
The world's oldest recorded tree is a 9,550 year old spruce in the Dalarna province of Sweden. The spruce tree has shown to be a tenacious survivor that has endured by growing between erect trees and smaller bushes in pace with the dramatic climate changes over time. view more (2008-04-17)
The desert is dying
Researchers from University of Bergen have found that trees, which are a main resource for desert people and their flocks, are in significant decline in the hyper-arid Eastern Desert of Egypt. view more (2007-02-14)
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)
