New study explores patterns in species diversity and genetic diversity
As scientists, conservationists, and policy-makers wrestle with how to balance development with maintaining biodiversity, it's important to understand what controls patterns of biodiversity and how the biodiversity of a system will respond to different environmental scenarios. view more (2005-07-27)
World's last great forest under threat: new study
The world's last remaining "pristine" forest - the boreal forest across large stretches of Russia, Canada and other northern countries - is under increasing threat, a team of international researchers has found. view more (2009-08-26)
UW-Madison tools help track Hurricane Ophelia
As Hurricane Ophelia is set to make landfall on the North Carolina coast on Wednesday or Thursday (Sept. 14 or 15), analysis techniques developed by researchers at the University of Wisconsin-Madison Tropical Cyclones group in the Cooperative Institute for Meteorological Satellite Studies are helping to predict the anticipated path of the storm. view more (2005-09-14)
Rove beetles act as warning signs for clear-cutting consequences
New research from the University of Alberta and the Canadian Forest Service has revealed the humble rove beetle may actually have a lot to tell us about the effects of harvesting on forests species. view more (2007-06-13)
Insect warning colors aid cancer and tropical disease drug discovery
Brightly colored beetles or butterfly larvae nibbling on a plant may signal the presence of chemical compounds active against cancer cell lines and tropical parasitic diseases, according to researchers at Smithsonian's Tropical Research Institute in Panama. view more (2008-07-09)
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 light gaps, opened up by treefalls. Rapid growth, a... view more...

First-ever 'State of the Carbon Cycle Report' finds troubling imbalance
The first "State of the Carbon Cycle Report" for North America, released online this week by the U.S. Climate Change Science Program, finds the continent's carbon budget increasingly overwhelmed by human-caused emissions. view more (2007-11-15)
"We are the champions" - the new birdie song
It's not just football supporters who join together in a rousing chorus to celebrate a victory. Winning a fight also appears to put the tropical boubou, an African bird, in the mood for a song. Research published in BMC Ecology describes a rare example of a context-specific birdsong and identifies the tropical boubou as the first bird species... view more... (2004-02-11)
America's national forests landlocked by sea of development
America's national forests are beginning to resemble "islands" of green wilderness, increasingly trapped by an expanding sea of new houses, a forestry researcher will report today at the 90th annual Ecological Society of America (ESA) meeting in Montreal, Canada. view more (2005-08-08)
Killer bees may increase food supplies for native bees
Aggressive African bees were accidentally released in Brazil in 1957. As "killer bees" spread northward, David Roubik, staff scientist at the Smithsonian Tropical Research Institute, began a 17-year study that revealed that Africanized bees caused less damage to native bees than changes in the weather and may have increased the... view more...

`Nature` highlights use of satellite imagery to study massive CO2 release in Indonesian fires
Writing in tomorrow’s issue of Nature magazine, a team of European and Indonesian scientists used satellite imagery from ESA’s ERS and NASA’s Landsat satellites to help measure the huge amounts of carbon dioxide gas released into the atmosphere by 1997-98 fires in the tropical bush of Indonesia. A series of peatland and forest... view more... (2002-11-06)
On the volcano island Krakatau: regeneration of rain forest goes hand in hand with genetic diversity
Rain-forest trees colonizing a new piece of land contain a large genetic diversity. The Indonesian island Krakatau is a good natural test case for disrupted tropical rain forest. Here, fig species hybridise unexpectedly. A lesson for the future of nature reserves. Just today, May 13, Tracey Parrish of the Netherlands Institute of Ecology... view more... (2002-05-13)
Tropical Storm Nepartak becoming extra-tropical at sea
Tropical Storm Nepartak is now speeding in a northeasterly direction in the northwestern Pacific Ocean, where it is becoming extra-tropical and developing frontal qualities. view more (2009-10-14)
Soil nutrition affects carbon sequestration in forests
On December 11, USDA Forest Service (FS) scientists from the FS Southern Research Station (SRS) unit in Research Triangle Park, NC, along with colleagues from Duke University, published two papers in The Proceedings of the National Academy of Science (PNAS) that provide a more precise understanding of how forests respond to increasing atmospheric... view more...

GOES-11 Sees Tropical Cyclones Fizzling and Forming in the Eastern Pacific
There are a lot of ups and downs in tropical cyclone formation in the Pacific Ocean this week, and that's keeping NOAA's GOES-11 satellite busy. There are remnants of Maka and Tropical Depression 9E, a fizzled Felicia, and a new Tropical Storm named Guillermo. view more (2009-08-14)
Tropical Storm Koppu Poised for China Landfall
The latest tropical storm in the western Pacific formed on Sunday, and is poised to make landfall in mainland China on Tuesday, near typhoon strength (74 mph). view more (2009-09-15)
Parasites a key to the decline of red colobus monkeys in forest fragments
Forest fragmentation threatens biodiversity, often causing declines or local extinctions in a majority of species while enhancing the prospects of a few. view more (2007-10-25)
Parasitic tropical diseases in the Americas, a legacy of slavery, can be eliminated
Although it has been speculated for more than a century that the slave trade was responsible for bringing many tropical diseases to the Americas, only recently has convincing evidence shown that lymphatic filariasis (elephantiasis), schistosomiasis, and onchocerciasis (river blindness) originated in this way. view more (2007-11-07)
UN body asks Lund Researchers to investigate new type of carbon sink
Trade in emission rights is intended to reduce global emissions of greenhouse gases. Countries with natural carbon sinks—areas that absorb more carbon dioxide than they give off—can ‘trade off’ that resource in return for their commitments to reduce emissions. Thus far this has largely involved forests. But now a new and... view more... (2001-11-09)
