Loss of Hemlocks Will Affect Water Dynamics in Southern Appalachian Forests
Forest Service (FS) research has provided the first estimates on the impact the loss of eastern hemlock will have on the water dynamics of the southern Appalachian mountains.   view more (2007-07-10)

Fires fuel mercury emissions, U-M study finds
Forest fires release more mercury into the atmosphere than previously recognized, a multidisciplinary research project at the University of Michigan suggests.   view more (2007-01-10)

First datasets for national biomass and carbon dataset now available
Scientists at the Woods Hole Research Center working to produce the "National Biomass and Carbon Dataset" for the year 2000 (NBCD2000) are releasing data from nine project mapping zones.   view more (2008-02-15)

Ume'å researchers have mapped the dams of the world
More than half of the world's large rivers are fragmented and regulated by dams. The largest and the most biologically and geographically diverse rivers are all affected. This is shown by a global study that is published in this week's issue of the journal Science.   view more (2005-04-14)

Challenges remain in reintroducing American chestnut
Researchers have developed a breed of American chestnut that is resistant to the fungal blight that decimated its population in the early 1900s.   view more (2007-08-23)

The critical importance of mangroves to ocean life
Mangroves, the backbone of the tropical ocean coastlines, are far more important to the global ocean's biosphere than previously thought.   view more (2006-02-28)

Scorched Earth millenium map shows 'fire scars'
A geographer from the University of Leicester has produced for the first time a map of the scorched Earth for every year since the turn of the Millennium.   view more (2008-05-23)

Frozen hair holds secrets of Yellowstone grizzlies
Locks of hair from more than 400 grizzly bears are stored at Montana State University, waiting to tell the tale of genetic diversity in the Yellowstone Ecosystem.   view more (2007-12-19)

Flowers shape themselves to guide their pollinators to the pollen
Why do flowers specialize on different pollinators? For example, both bats and hummingbirds pollinate plants in tropical forests; why adapt to just one instead of using both? Biologists often assume that tradeoffs contribute to such specialization (the jack of all pollinators is master of none),... view more (2007-04-04)

Human settlements already existed in the Amazon Basin (Equador) 4000 years ago
An important discovery by IRD archaeologists in Equador reveals that, more than 4000 years ago, early Andean civilizations had become established in a tropical environment where they were not hitherto known to have existed. This finding pushes further back the presumed beginning of developed... view more (2003-07-04)

South Pacific plant may be missing link in evolution of flowering plants
A new University of Colorado at Boulder study involving a "living fossil plant" that has survived on Earth for 130 million years suggests its novel reproductive structure may be a "missing link" between flowering plants and their ancestors.   view more (2006-05-18)

The cost of long tongues
Orchid bees use their extraordinarily long tongues to drink nectar from the deep, tropical flowers only they can access.   view more (2007-04-17)

Environmental lessons from tsunami as world's coastal population doubles
Coastal populations and ecosystems are more likely to bounce back from extreme coastal disasters by protecting local environments and building on local knowledge, according to a report published in Science.   view more (2005-08-12)

Mangroves key to saving lives
The replanting of mangroves on the coasts of the Philippines could help save many of the lives lost in the 20-30 typhoons that hit the islands annually.    view more (2008-07-22)

"Acid rain" and forest mass: another perspective
A few years ago the study of the effects of atmospheric deposition on forest ecosystems reached beyond the scientific sphere and the term "acid rain" was coined.   view more (2005-10-14)

Drop in acid rain altering Appalachian stream water
Appalachian hardwood forests may be getting a respite from acid rain but data from a long-term ecological study of stream chemistry suggests that the drop in acid rain may be changing biological activity in the ecosystem and hiking dissolved carbon dioxide in forest streams.   view more (2006-12-12)

Declining snowpack cools off CO2 emissions from winter soils, says U. of Colorado study
A recent decrease in Rocky Mountain snowpack has slowed the release of heat-trapping carbon dioxide gases from forest soils into the atmosphere during the dead of winter.   view more (2006-02-09)

Size of herd determines status and access to resources in Kenya
Less livestock wealth, means less chance of access to arable land, grain production and friends. Kenyan and Dutch researchers Adano Roba and Karen Witsenburg have discovered that this is the hard truth faced by poor households in North Kenya. They therefore argue that poverty alleviation measures... view more (2004-11-17)

Woods Hole Research Center plans controlled burn in Amazon rainforest
Fire is an important agent of transformation in the Amazon landscape. Every year, low intensity fires burn thousands of square miles of Amazon forest.   view more (2005-07-20)

MIT's ocean model precisely mimics microbes' life cycles
Scientists at MIT have created an ocean model so realistic that the virtual forests of diverse microscopic plants they "sowed" have grown in population patterns that precisely mimic their real-world counterparts.   view more (2007-03-30)

Oil and gas projects in western Amazon threaten biodiversity and indigenous peoples
The western Amazon, home to the most biodiverse and intact rainforest left on Earth, may soon be covered with oil rigs and pipelines.   view more (2008-08-13)

Amur leopard still on the brink of extinction, scientists say
A new census of the world's most endangered cat, the Amur or Far Eastern leopard (Panthera pardus orientalis), shows that as few as 25 to 34 are left in the wild, renewing fears for the future of the species.   view more (2007-04-18)

Study says eyes evolved for X-Ray vision
The advantage of using two eyes to see the world around us has long been associated solely with our capacity to see in 3-D. Now, a new study from a scientist at Rensselaer Polytechnic Institute has uncovered a truly eye-opening advantage to binocular vision: our ability to see through things.   view more (2008-08-29)

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)

Yellow fever threatens to make a come back
Yellow fever has been written off in the past as a global threat. Yet the failure to eradicate this disease has left the door open for new, large, outbreaks as vaccination of travellers and tropical populations declines, according to an article in the February issue of Microbiology Today magazine... view more (2002-02-11)
