Australia's climate: Drought and flooding in annual rings of tropical trees
Annual rings are acclaimed in representing natural climate archives. For the temperate latitudes it is known that the growth of these annual rings depend mainly on temperature and precipitation. view more (2009-06-12)
Exotic timber plantations found to use more than twice the water of native forests
Ecologists have discovered that timber plantations in Hawaii use more than twice the amount of water to grow as native forests use. view more (2009-09-16)
Global warming threatens tropical species, the ecosystem and its by-products
Tropical lizards detect the effects of global warming in a climate where the smallest change makes a big difference, according to herpetologist Laurie Vitt, curator of reptiles and George Lynn Cross Research Professor at the University of Oklahoma's Sam Noble Museum of Natural History view more (2009-08-26)
Looming tropical disaster needs urgent action
A major review by University of Adelaide researchers shows that the world is losing the battle over tropical habitat loss with potentially disastrous implications for biodiversity and human well-being. view more (2008-06-25)
Without disturbances in nature the world's forests will be impoverished
The forests of the world are not the stable and unchanging ecosystems they have been assumed to be. Without the occurrence of wide-spread disturbances in nature, such as forest fires, icing, or volcanic activity, forests will eventually be impoverished, owing to a lack of phosphorous. This is shown in a study reported in this week's issue of the... view more... (2004-06-21)
Study shows housing development on the rise near national forests
America's national forests and grasslands provide the largest single source of freshwater in the United States, habitat for a third of all federally listed threatened or endangered species, and recreation opportunities for people (about 205 million visits are made annually to national forests). view more (2007-10-26)
Trees to offset the carbon footprint?
How effective are new trees in offsetting the carbon footprint? A new study suggests that the location of the new trees is an important factor when considering such carbon offset projects. Planting and preserving forests in the tropics is more likely to slow down global warming. view more (2007-04-10)
Northern forests less effective than tropical forests in reducing global warming
Forests in the United States and other northern mid- and upper-latitude regions are playing a smaller role in offsetting global warming than previously thought, according to a study appearing in this week's issue of Science. view more (2007-06-25)
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)
Satellites show Amazon parks, indigenous reserves stop forest clearing
In a paper recently published in Conservation Biology (2006, Vol 20, pages 65-73), an international team of scientists, led by Daniel Nepstad of the Woods Hole Research Center and the Instituto de Pesquisa Ambiental da Amazonia, use satellite data to demonstrate, for the first time, that rainforest parks and indigenous territories halt... view more...

Soil fertility in the tropics can be influenced by landscape and precipitation, study finds
A new study conducted in the Hawaiian Islands has revealed that landscape and erosion play crucial roles in determining soil fertility in tropical ecosystems. view more (2005-07-20)
Can you rescue a rainforest? The answer may be yes
Half a century after most of Costa Rica's rainforests were cut down, researchers from the Boyce Thompson Institute took on a project that many thought was impossible - restoring a tropical rainforest ecosystem. view more (2008-03-28)
New study finds biodiversity conservation secures ecosystem services for people
Healthy ecosystems that provide people with essential natural goods and services often overlap with regions rich in biological diversity, underscoring that conserving one also protects the other, according to a new study. view more (2007-12-06)
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)
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 of plant species in tropical forests. view more (2006-11-29)
Wildfires result in loss of forests reserved by Northwest Forest Plan
Although the Northwest Forest Plan (NWFP) significantly reduced cutting of old-growth forests on federal land, forests in the driest regions are now at greater risk of being lost to wildfire than to logging. view more (2008-11-07)
Rain forest protection works in Peru
A new regional study shows that land-use policies in Peru have been key to tempering rain forest degradation and destruction in that country. view more (2007-08-10)
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 agricultural societies in the western Amazon Basin. It... view more... (2003-07-04)
Turtle nesting threatened by logging practices in Gabon, Smithsonian warns
Endangered sea turtles are victims of sloppy logging practices in the west central African country Gabon, according to a study led by William Laurance, staff scientist at the Smithsonian Tropical Research Institute. The study will be published online in the journal Oryx later this month. view more (2008-03-17)
More species in the tropics because species have been there longer
Why are there more species in the tropics than in the temperate regions of the globe? Many of the world's species live in the tropics (perhaps more than half), but the reason has been debated for more than 100 years. view more (2006-11-02)
