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)
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)
Soil fertility in the tropics can be influenced by landscape and precipitation, study finds

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 tropical forests globally have warmed by half a... view more... (2004-02-06)
Hurricane frequency is up but not their strength, say Clemson researchers
In a new study, Clemson University researchers have concluded that the number of hurricanes and tropical storms in the Atlantic Basin is increasing, but there is no evidence that their individual strengths are any greater than storms of the past or that the chances of a U.S. strike are up. view more (2009-09-23)
U of M study finds new insight on therapy for a devastating parasitic disease
University of Minnesota Medical School researchers have discovered an important new insight into how a commonly prescribed drug may work to treat those infected by a parasitic flatworm. view more (2009-06-24)
Researchers link Ice Age climate-change records to ocean salinity
Sudden decreases in temperature over Greenland and tropical rainfall patterns during the last Ice Age have been linked for the first time to rapid changes in the salinity of the north Atlantic Ocean. view more (2006-10-05)
Measurement of the extent of pest damage to rice crops in tropical Asia to establish control priorities
Although rice is the world's primary food crop, studies on pest and disease injury are rare and there is surprisingly little detailed knowledge on the problem. It is essential to know the harmfulness of the agents that affect the crops - bacteria, viruses, fungi, weeds or insects - if control strategies are to be elaborated and intervention... view more...

Scientists: As rainfall changes, tropical plants may acclimate
Tropical plants may be more adaptable than commonly thought to changing rainfall patterns expected to accompany a warming climate, new research shows. view more (2007-05-08)
Population movement can be critical factor in dengue's spread
Human movement is a key factor of dengue virus inflow in Rio de Janeiro, according to results from researchers based at the Oswaldo Cruz Foundation (Fiocruz) in Brazil. view more (2009-11-10)
Forgotten, but not gone: Leprosy still present in the US
Long believed to be a disease of biblical times, leprosy, also known as Hansen's disease, continues to be seen in the United States. "Approximately 150 cases are diagnosed each year with 3,000 people in the U.S. currently being treated for leprosy. view more (2008-11-07)
Predicting mosquito outbreaks for disease control
University of Adelaide researchers have shown they can predict the biggest population peaks of disease-carrying mosquitoes up to two months ahead. view more (2009-03-24)
Substantial costs and underreporting of dengue fever, concerns about blood supply face US
Dengue fever, known as "breakbone fever" because of the excruciating back and joint pain that accompanies this infectious disease, is a growing public health threat for people living in tropical countries, as well as travelers to destinations such as Thailand, Brazil and Puerto Rico. view more (2007-10-17)
Free smoke alarms to poor local authority households are a waste of time and money
Local authority schemes aimed at reducing fire-related injuries and deaths in poor urban households by providing and installing free smoke alarms could be a waste of time and money, according to a study carried out by researchers from the London School of Hygiene & Tropical Medicine. The study, the findings of which are published in today's... view more... (2002-10-31)
Local climate influences dengue transmission
Researchers from the US Centers for Disease Control and Prevention (CDC) and the Johns Hopkins Bloomberg School of Public Health have found that dengue transmission in Puerto Rico is dependent upon local climate and short-term changes in temperature and precipitation. view more (2009-02-17)
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)
Long-term increase in rainfall seen in tropics

Bacterial pathogens and rising temperatures threaten coral health
Coral reefs around the world are in serious trouble from pollution, over-fishing, climate change and more. The last thing they need is an infection. But that's exactly what yellow band disease (YBD) is-a bacterial infection that sickens coral colonies. view more (2009-01-20)
Panama butterfly migrations linked to El Niño, climate change
A high-speed chase across the Panama Canal in a Boston Whaler may sound like the beginning of another James Bond film-but the protagonist of this story brandishes a butterfly net and studies the effects of climate change on insect migrations at the Smithsonian Tropical Research Institute. view more (2009-10-06)
