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)

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)

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)

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)

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)

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)

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)

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)

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)

No convincing evidence for decline in tropical forests
Claims that tropical forests are declining cannot be backed up by hard evidence, according to new research from the University of Leeds.   view more (2008-01-08)

New study warns limited carbon market puts 20 percent of tropical forest at risk
In an ironic twist, 11 countries that have avoided widespread destruction of their tropical forest are at risk of being left out of an emerging carbon market intended to promote rainforest conservation to combat climate change.   view more (2007-08-14)

Extinction most likely for rare trees in the Amazon rainforest
Common tree species in the Amazon will survive even grim scenarios of deforestation and road-building, but rare trees could suffer extinction rates of up to 50 percent, predict Smithsonian scientists and colleagues in the Aug. 12 issue of the journal Proceedings of the National Academy of Science.    view more (2008-08-14)

Earth's first rainforest unearthed
A spectacular fossilised forest has transformed our understanding of the ecology of the Earth's first rainforests. It is 300 million years old.   view more (2007-04-23)

Study of Tropical Forests Worldwide Reveals that Nature Encourages Diversity
An analysis of seven tropical forests around the world has found that nature encourages diversity by selecting for less common trees as the trees mature.   view more (2006-01-27)

Diversity of trees in Ecuador's Amazon rainforest defies simple explanation
Trees in a hyper-diverse tropical rainforest interact with each other and their environment to create and maintain diversity, researchers report in the Oct. 24 issue of the journal Science.    view more (2008-10-24)

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)

Singing in the rainforest: Public vs. private signaling by a tropical rainforest bird
According to the Chinese proverb, a bird sings because it has a song, not because it has an answer. A team of French and Brazilian researchers, however, may have the answer as to how the song of Brazilian white-browed warbler has become so well-adapted to the acoustic properties of the rainforest... view more (2008-02-13)

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)

The Influence Of Disturbance On Tropical Rain Forest Biodiversity : End Of A Controversy In Sight

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)

Mode of seed dispersal greatly shapes placement of rainforest trees
The apple might not fall far from the tree, but new research shows that how it falls might be what is most important in determining tree distribution across a forest. This study of the seed dispersal methods of rainforest trees demonstrates that these methods play a primary role in the organization... view more (2006-11-29)

Vine invasion? UWM ecologist looks at coexistence of trees and lianas
Among the hundreds of species of woody vines that University of Wisconsin-Milwaukee ecologist Stefan Schnitzer has encountered in the tropical forests of Panama, the largest has a stalk nearly 20 inches in circumference.   view more (2008-08-06)

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)

Developing nations may save the tropical forest
In an article this Friday (April 14) in the international magazine New Scientist, a leading rainforest biologist from the Smithsonian Tropical Research Institute in Panama argues that a new initiative by developing nations offers great promise to help reduce the rampant rate of tropical forest... view more (2006-04-12)
