Tropical forests leak nitrogen back into atmosphere, say scientists
In findings that could influence our understanding of climate change, a Princeton research team has learned that tropical forests return to the atmosphere up to half the nitrogen they receive each year, thanks to a particular type of bacteria that lives in those forests.   view more (2006-05-23)

Study: Rain forest insects eat no more tree species than temperate counterparts
A study initiated by University of Minnesota plant biologist George Weiblen has confirmed what biologists since Darwin have suspected-that the vast number of tree species in rain forests accounts for the equally vast number of plant-eating species of insects.   view more (2006-08-24)

Madagascan tropical forests return thanks to better management and well-defined ownership
A study published in the May 2nd issue of the online, open-access journal PLoS ONE, shows that although loss of tropical dry forests occurs in southern Madagascar, there are also large areas of forests regenerating.   view more (2007-05-02)

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)

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)

The future of tropical forests
Deforestation and habitat loss are expected to lead to an extinction crisis among tropical forest species. Humans in rural settings contribute most to deforestation of extant tropical forests.   view more (2006-04-07)

ESA providing Kyoto estimates of French Guiana's tropical forests
ESA is providing data from its Earth observation satellites to monitor the tropical forests in French Guiana and help the French government meet its obligations under the international Kyoto Protocol agreement on global warming. Like all the so-called "Annex I" signatories to the Kyoto... view more (2003-06-05)

"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... view more (2005-04-19)

Confirmed - deforestation plays critical climate change role
Dr Pep Canadell, from the Global Carbon Project and CSIRO Marine and Atmospheric Research, says today in the journal Science that tropical deforestation releases 1.5 billion tonnes of carbon each year into the atmosphere.   view more (2007-05-14)

Drought sensitivity shapes species distribution patterns in tropical forests
Looking at a rainforest it's easy to see that there are hundreds of different tropical plant species that inhabit the forest. Although the patterns of plant distributions in tropical forests have been widely studied, the reasonings behind these patterns are not as well known.   view more (2007-05-15)

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)

Nitrogen pollution boosts plant growth in tropics by 20 percent
A study by UC Irvine ecologists finds that excess nitrogen in tropical forests boosts plant growth by an average of 20 percent, countering the belief that such forests would not respond to nitrogen pollution.   view more (2008-02-07)

Scientists must offer solutions for conserving tropical forests in a rapidly changing world
As human populations and their impacts on the world increase, tropical forests are changing in many different ways. Forests are being cleared, burned, logged, fragmented, and overhunted and an unprecedented pace.   view more (2005-09-06)

Scientists may have solved an ecological riddle
A team of scientists may have solved the riddle of why plants that work with bacteria to convert atmospheric nitrogen gas into an essential biological nutrient (ammonia) tend to prevail in the world's tropical regions rather than higher latitudes.   view more (2008-06-19)

Direct link established between tropical tree and insect diversity
Higher tree species diversity leads directly to higher diversity of leaf-eating insects.   view more (2006-07-19)

Tropical rainforest nutrients linked to global carbon dioxide levels
Extra amounts of key nutrients in tropical rain forest soils cause them to release more carbon dioxide into the atmosphere, according to research conducted by scientists at the University of Colorado (CU)—Boulder.   view more (2006-06-21)

Seeing the forest and the trees
With human emissions of carbon dioxide on the rise, there is growing interest in maintaining the Earth's natural mechanisms that absorb and store carbon.   view more (2005-10-24)

The drivers of tropical deforestation are changing, say scientists
A shift from poverty-driven to industry-driven deforestation threatens the world's tropical forests but offers new opportunities for conservation, according to an article coauthored by William Laurance of the Smithsonian Tropical Research Institute in Panama.   view more (2008-08-06)

New method for measuring biodiversity
German and Sri Lankan researchers have developed a new method for measuring the impacts of species on local biodiversity. It makes it possible to determine whether a certain species promotes or suppresses species diversity.   view more (2008-02-19)

Brazil demonstrating that reducing tropical deforestation is key win-win global warming solution
Tropical deforestation is the source of nearly a fifth of annual, human-induced emissions of heat-trapping gases to the atmosphere.   view more (2007-05-16)

Soil nutrients shape tropical forests, large-scale study indicates
Tropical forests are among the most diverse plant communities on earth, and scientists have labored for decades to identify the ecological and evolutionary processes that created and maintain them.   view more (2007-01-12)

Drought limits tropical plant distributions, scientists at the Smithsonian report
Drought tolerance is a critical determinant of tropical plant distributions, researchers working at the Smithsonian Tropical Research Institute in Panama report in the journal Nature, May 3.   view more (2007-05-03)

Tropical insects 'go the distance' to inform rainforest conservation
The long-held belief that plant-eating insects in tropical forests are picky eaters that stay "close to home" - dining only on locale-specific vegetation - is being challenged by new research findings that suggest these insects feast on a broader menu of foliage and can be consistently... view more (2007-08-10)

New Evidence Of Impact Of Global Changes On Remote Tropical Rainforests
Scientists have shed new light on the impact of global environmental changes on remote tropical forests with studies that show that the rates of growth and death of trees in pristine forests across the Amazon have accelerated substantially in recent decades. The scientists also demonstrate that the... view more (2004-02-06)

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)
