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)
Workshop assesses interactions between climate, forests and land use in the Amazon Basin
On February 25 and 26, over 50 scientists gathered for a two-day workshop in Manaus, Brazil, to discuss the current state of knowledge on the feedbacks between deforestation and climate in the Amazon and what research is required to avoid catastrophic change. view more (2008-03-13)
Amazon powers tropical ocean's carbon sink
Nutrients from the Amazon River spread well beyond the continental shelf and drive carbon capture in the deep ocean, according to the authors of a multi-year study. view more (2008-07-22)
Plant fossils give first real picture of earliest Neotropical rainforests
A team of researchers including a University of Florida paleontologist has used a rich cache of plant fossils discovered in Colombia to provide the first reliable evidence of how Neotropical rainforests looked 58 million years ago. view more (2009-10-16)
Developing nations may save the tropical forest
In an article this Friday (April 14) in the international magazine New Scientist, a leading rainforest biologist from the Smithsonian Tropical Research Institute in Panama argues that a new initiative by developing nations offers great promise to help reduce the rampant rate of tropical forest destruction. view more (2006-04-12)
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)
Tipping elements in the Earth's climate system
Anthropogenic forcing could push the Earth's climate system past critical thresholds, so that important components may "tip" into qualitatively different modes of operation. view more (2008-02-05)
U.N. Climate Change Conference considers ancient soil replenishment technique in battle against global warming
Former inhabitants of the Amazon Basin enriched their fields with charred organic materials-biochar-and transformed one of the earth's most infertile soils into one of the most productive. view more (2008-12-18)
New study warns limited carbon market puts 20 percent of tropical forest at risk
In an ironic twist, 11 countries that have avoided widespread destruction of their tropical forest are at risk of being left out of an emerging carbon market intended to promote rainforest conservation to combat climate change. view more (2007-08-14)
New wireless sensor network keeps tabs on the environment
Research in the University of Alberta's Faculty of Science may soon be able to answer that question. The departments of computing science and earth and atmospheric science have been working together to create a Wireless Sensor Network that allows for the clandestine data collection of environmental factors in remote locations and its monitoring... view more...

NASA study improves ability to predict aerosols' effect on cloud cover
Using a novel theoretical approach, researchers from NASA and other institutions have identified the common thread that determines how aerosols from human activity, like the particles from burning of vegetation and forests, influence cloud cover and ultimately affect climate. view more (2008-08-15)
Watching over the Amazon forest by remote sensing
Areas deforested in Brazil increased from 152 000 km_ in 1976 to 517 000 km_ in 1996. That figure is the equivalent of the surface area of France (1). Deforestation is a complex process and involves a host of changing and widely differing situations. The factors behind it are many and varied. They include rising demand for agricultural land,... view more... (2003-04-29)
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)
Fire, ice, and invasion
The November 2007 Special Issue of Frontiers in Ecology and the Environment focuses on paleoecology, which uses fossilized remains and soil and sediment cores to reconstruct past ecosystems. view more (2007-11-15)
The Amazon : wedding in white and black
What happens when two rivers of widely different character meet? In order to answer this question, hydrologists from IRD (Institut de recherché pour le développement) have examined the confluence of the Rivers Negro and Solim'΅es, in Brazil. These two large water courses join just downstream from Manaus to form the Amazon. Up to now,... view more... (2000-11-07)
Rio Napo Mission 2004 in the Amazonian regions of Ecuador and Peru , 15 October-1 November
In 1541, the Spanish conquistador Francisco de Orellana embarked on the River Napo in Ecuador. This began his venture to go down the Amazon and reach the Atlantic Ocean. Aiming to retrace his journey, research teams of about 20 scientists from the IRD and several Ecuadorian, Bolivian, Peruvian and Brazilian institutes are to follow part of his... view more...

Woods Hole Research Center plans controlled burn in Amazon rainforest
Fire is an important agent of transformation in the Amazon landscape. Every year, low intensity fires burn thousands of square miles of Amazon forest. view more (2005-07-20)
Woods Hole Research Center debuts new image mosaic that will strengthen global forest monitoring
Much of the discussion at the upcoming United Nations Climate Change Conference in Bali, Indonesia, will focus on monitoring tropical deforestation and the critical role that remote sensing systems will play in the development of REDD (Reduced Emissions from Deforestation and Degradation) mechanisms - policies designed to compensate rainforest... view more...

Warriors do not always get the girl
Aggressive, vengeful behavior of individuals in some South American groups has been considered the means for men to obtain more wives and more children, but an international team of anthropologists working in Ecuador among the Waorani show that sometimes the macho guy does not do better. view more (2009-05-12)
African sweetener
One present-day form of colonialism works like this: A company sends researchers into the rainforest to discover promising new natural substances. Once found, the company registers a patent or trademark and begins to cash-in. Even more effective is the latest variant: Instead of using the plant itself, the relevant gene is isolated and... view more... (2004-01-05)
