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)
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)
The Role Of Sexually Transmitted Diseases, Malaria, And Tuberculosis On The Hiv-1/Aids Epidemic In Africa (p 2177)
The effect of HIV-1 on other infectious diseases in Africa is an increasing public health concern. In a review in this week's issue of THE LANCET, Elizabeth Corbett from the London School of Hygiene and Tropical Medicine, UK, and the Harare Biomedical Research and Training Institute, Zimbabwe, and colleagues describe the role that three major... view more...

Satellite survey links tropical park fires with poverty and corruption
According to the first global assessment of forest fire control effectiveness in tropical parks, poverty and corruption correlate closely with lack of fire protection in tropical moist forests. view more (2007-07-10)
A change in the wind
Climate model simulations for the 21st century indicate a robust increase in wind shear in the tropical Atlantic due to global warming, which may inhibit hurricane development and intensification. view more (2007-04-18)
Scientists decode genome of deadly parasitic worm
Scientists have sequenced the genome of the parasite that causes intestinal schistosomiasis (also known as bilharzia or snail fever), a devastating tropical disease that afflicts more than 200 million people in the developing world. view more (2009-07-16)
Waterborne infectious diseases could soon be consigned to history, says expert
Waterborne infectious diseases, which bring death and illness to millions of people around the world, could largely be consigned to history by 2015 if global health partnerships integrate their programmes. view more (2006-08-25)
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)
Food security for leaf-cutting ants: Workers and their fungus garden reject endophyte invaders
New diseases directly affect human survival and food security, especially as population density climbs. Leaf-cutting ants, one of a few groups of social insects to cultivate crops, have harvested plant material to fertilize their underground fungal gardens for ~50 million years. view more (2009-04-03)
Community spread of trachoma could be stopped by treating all household members
All members of the household need to be treated for trachoma in order to prevent rapid re-infection, according to a new study published in PLoS Neglected Tropical Diseases. view more (2009-03-31)
Scientists use lasers to measure changes to tropical forests
New technology deployed on airplanes is helping scientists quantify landscape-scale changes occurring to Big Island tropical forests from non-native plants and other environmental factors that affect carbon sequestration. view more (2009-01-26)
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)
NASA satellites catch 2 views of Felicia already affecting Hawaii
Tropical Storm Felicia is closing in on the Hawaiian Island chain and its center is now expected to pass just north of the big island before moving through the islands Tuesday and Wednesday. view more (2009-08-11)
Bioprospecting not biopiracy
By training professionals in high-biodiversity regions to advance the drug discovery process in-country, a novel program drives drug discovery costs down as it promotes tropical biodiversity conservation. view more (2006-12-08)
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)
Two NASA Satellites Captures Hurricane Bill's
Bill was the third tropical depression in the Atlantic Ocean hurricane season, behind Ana and Tropical Depression One. Over the weekend Bill grew into the first hurricane in the Atlantic this season. Two NASA Satellites captured Bill's rainfall and cloud temperatures as he was powering up. view more (2009-08-18)
Frequency of Atlantic hurricanes doubled over last century, climate change suspected
About twice as many Atlantic hurricanes form each year on average than a century ago, according to a new statistical analysis of hurricanes and tropical storms in the north Atlantic. view more (2007-07-30)
Man-Made Climate Change
A new study published in this week's issue of Nature is the first to show that human activity is altering the circulation of the tropical atmosphere and ocean through global warming. view more (2006-05-04)
NASA Eyes Category 4 Hurricane Felicia and a Stubborn Enrique
Felicia is the storm that rules the Eastern Pacific Ocean this week, but Enrique refuses to give up. Felicia is a major hurricane with sustained winds near 140 mph, and Enrique is still hanging onto tropical storm status with 50 mph sustained winds. view more (2009-08-07)
Global Warming Surpassed Natural Cycles in Fueling 2005 Hurricane Season, NCAR Scientists Conclude
Global warming accounted for around half of the extra hurricane-fueling warmth in the waters of the tropical North Atlantic in 2005, while natural cycles were only a minor factor. view more (2006-06-23)
