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)
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)
Parasitic tropical diseases in the Americas, a legacy of slavery, can be eliminated
Although it has been speculated for more than a century that the slave trade was responsible for bringing many tropical diseases to the Americas, only recently has convincing evidence shown that lymphatic filariasis (elephantiasis), schistosomiasis, and onchocerciasis (river blindness) originated in this way. view more (2007-11-07)
UW-Madison tools help track Hurricane Ophelia
As Hurricane Ophelia is set to make landfall on the North Carolina coast on Wednesday or Thursday (Sept. 14 or 15), analysis techniques developed by researchers at the University of Wisconsin-Madison Tropical Cyclones group in the Cooperative Institute for Meteorological Satellite Studies are helping to predict the anticipated path of the storm. view more (2005-09-14)
Yellow fever threatens to make a come back
Yellow fever has been written off in the past as a global threat. Yet the failure to eradicate this disease has left the door open for new, large, outbreaks as vaccination of travellers and tropical populations declines, according to an article in the February issue of Microbiology Today magazine from the Society for General Microbiology. "Yellow... view more... (2002-02-11)
"We are the champions" - the new birdie song
It's not just football supporters who join together in a rousing chorus to celebrate a victory. Winning a fight also appears to put the tropical boubou, an African bird, in the mood for a song. Research published in BMC Ecology describes a rare example of a context-specific birdsong and identifies the tropical boubou as the first bird species... view more... (2004-02-11)
'Dodgy dossier' partly to blame for failure of war against malaria in the tropics
The war against malaria in tropical countries was fought and lost in the 20th Century on the basis of faulty intelligence, a 'dodgy dossier' which argued that the same methods used to tackle the disease in temperate countries would also work in the tropics. view more (2008-09-11)
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 Storm Nepartak becoming extra-tropical at sea
Tropical Storm Nepartak is now speeding in a northeasterly direction in the northwestern Pacific Ocean, where it is becoming extra-tropical and developing frontal qualities. view more (2009-10-14)
GOES-11 Sees Tropical Cyclones Fizzling and Forming in the Eastern Pacific
There are a lot of ups and downs in tropical cyclone formation in the Pacific Ocean this week, and that's keeping NOAA's GOES-11 satellite busy. There are remnants of Maka and Tropical Depression 9E, a fizzled Felicia, and a new Tropical Storm named Guillermo. view more (2009-08-14)
Tropical Storm Koppu Poised for China Landfall
The latest tropical storm in the western Pacific formed on Sunday, and is poised to make landfall in mainland China on Tuesday, near typhoon strength (74 mph). view more (2009-09-15)
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)
Neglected tropical diseases burden those overseas, but travelers also at risk
Though little known to most Americans, lymphatic filariasis, trachoma, leishmaniasis, onchocerciasis, schistosomiasis and other so-called neglected tropical diseases are responsible for severe health burdens, especially among the world's poorest people. view more (2007-12-26)
Microwave satellite imagery shows an eye developing in Mirinae
Microwave satellite imagery has revealed that Tropical Storm Mirinae is strengthening enough to develop an eye, and that's what it's doing. Mirinae was formerly Tropical Depression 23W, but became a tropical storm and received its name. view more (2009-10-28)
The Philippines may finally get a break from Tropical Depression Parma
The Philippines can't seem to get rid of what is now a deadly and annoying Tropical Depression Parma, but forecasters are now providing hope. view more (2009-10-09)
Why does species diversity vary so much?
The diversity of life varies predictably with climate and is greatest where it is warm and wet (the humid tropics). But the question "why" has puzzled biologists for over a century. In the December issue of Ecology Letters, Currie and colleagues examine three hypotheses about the origin of climatic gradients of diversity. The... view more... (2005-01-11)
Henri born in Eastern Atlantic... could be short-lived
Forecasters were watching a storm they designated as 91 yesterday, October 6, until it organized into a tropical cyclone east of the Leeward Islands around 5 p.m. EDT. It was then named "Tropical Storm Henri," the eighth named tropical cyclone of the Atlantic hurricane season. view more (2009-10-08)
Tropical medicine: a brittle tool of the new imperialism (p 1087)
This week's Lancet editorial is strongly critical of the way that tropical medicine remains structured on outdated colonial lines and calls for the discipline to 'resist contemporary imperialistic forces that hide under the folded veils of counterterrorism and corporate colonialism'. THE LANCET charges tropical medicine with rewriting its history... view more... (2004-03-31)
Still a Low Chance of Development for Two Lows
The two areas of thunderstorms in the Caribbean from yesterday, July 21, are on the move. One area is now moving into out of the Caribbean and into the eastern Atlantic Ocean while the other is now moving over the southeastern Bahamas and Hispaniola on a northwest track. view more (2009-07-23)
