NASA Satellite Tracking Typhoon Lupit on a March Toward the Northern Philippines
Three instruments on NASA's Aqua satellite captured views of Typhoon Lupit on its western track toward the Philippines and are helping forecasters get an idea of its strength and behavior. Lupit strengthened quickly in 24 hours from a tropical depression to a typhoon, between October 15 and 16. view more (2009-10-19)
Cutting-edge health care training in Africa
Oxford University researchers are developing a pilot `E-learning Certification Programme in Global Health` directed at health professionals working in Africa, following a donation of US $500,000 (£325,000) from the Bill & Melinda Gates Foundation. Increasing strains on the health care system in many African countries created by AIDS and... view more... (2002-10-25)
HUMIDITY INDUCES MELTING IN TROPICAL-ZONE GLACIERS
On Zongo glacier in Bolivia, situated at between 6000 and 4900 m elevation on the Huayna Potosi massif, 30 km from La Paz, scientists have observed that the runoff stream, induced by ice melting, showed a discharge rate two or three times lower during the dry season (May to August at this latitude) than that in the wet season (November to... view more...

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 found across hundreds of miles of tropical... view more...

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)
Major discovery opens door to leishmania treatment
Leishmania is a deadly parasitic disease that affects over 12 million people worldwide, with more than 2 million new cases reported every year. view more (2009-10-07)
NASA Africa mission investigates origin, development of hurricanes
Scientists from NASA, the National Oceanic and Atmospheric Administration, universities and international agencies will study how winds and dust conditions from Africa influence the birth of hurricanes in the Atlantic Ocean. view more (2006-07-27)
Orangutans unique in movement through tree tops
Movement through a complex meshwork of small branches at the heights of tropical forests presents a unique challenge to animals wanting to forage for food safely. view more (2009-07-28)
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)
Almost 7 million pregnant in sub-Saharan Africa infected with hookworms; at risk of anaemia
A study published today in the open-access journal PLoS Neglected Tropical Diseases reveals that between a quarter and a third of pregnant women in sub-Saharan Africa, or almost 7 million, are infected with hookworms and at increased risk of developing anaemia. view more (2008-09-18)
Smithsonian puts tropical Eastern-Pacific shore fishes online
A new bilingual online information system created by D. Ross Robertson, staff scientist at the Smithsonian Tropical Research Institute, and Coeus Knowledge Systems makes it possible for conservationists, sport fishers, tourists, researchers, students and resource managers to identify and generate publishable maps for 1,287 tropical eastern Pacific... view more...

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
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)
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)
How much is the world spending on neglected disease research and development?
The first comprehensive survey of global spending on neglected disease R&D, published in this week's PLoS Medicine, finds that just over $US 2.5 billion was invested into R&D of new products in 2007, with three diseases-HIV/AIDS, TB, and malaria-receiving nearly 80% of the total. view more (2009-02-04)
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)
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)
The Influence Of Disturbance On Tropical Rain Forest 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...
