(05/02/2007) Drought could cause dramatic shifts in rainforest plant communities in Central America, reports a new study published in the May 3 issue of Nature. The research shows that many rainforest plants are ill-equipped to deal with extended dry periods, putting them at elevated risk from changes in climate projected for the region.
(04/25/2007) Brazil will divide its environmental protection agency IBAMA into two separate entities reports Reuters. The move is expected to speed development projects in the Amazon rainforest.
(04/18/2007) The rapid expansion of soybean cultivation in the Amazon may be having a larger impact on climate than previously believed, according to research published last week in Geophysical Research Letters. Using experimental plots in the Amazon, a team of scientists led by Marcos Costa from the Federal University of Vicosa in Brazil found that clearing for soybeans increases the reflectivity or albedo of land, reducing rainfall by as much as four times relative to clearing for pasture land.
(04/09/2007) Slovenian marathon swimmer Martin Strel became the first person to swim the entire length of the Amazon River Saturday when he arrived in Belem, Brazil. Strel was immediately taken to the hospital in critical condition but is now recovering in a local hotel.
(03/30/2007) Brazil will offer free satellite Internet connections to indigenous tribes in the Amazon according to a report from Reuters. It says that the plan will help reduce illegal logging by enabling natives to monitor and report on illicit activities.
(03/19/2007) Used for centuries as a natural disease prevention and physical stimulant, an Amazonian tree frog has become a symbol of Brazil's fight to benefit the Indigenous from scientific developments based on their knowledge.
(03/14/2007) Fires are nothing new to the Amazon reports a study published in the journalBiotropica. Analyzing soils in the eastern Amazon, a team of scientists led by David S. Hammond of NWFS Consulting, has found evidence of forest fires dating back thousands of years. While the origin of these fires is unclear, the authors propose intriguing scenarios involving pre-Colombian human populations and ancient el Nino events which could have so dried rainforest areas that they became more prone to forest fires.
(03/12/2007) Brazil's second largest exporter of beef has won approval of a controversial loan from the International Finance Corporation (IFC), the private equity lender of the World Bank, according to a report from the Associated Press. Environmentalists say the deal will drive further deforestation in the biologically rich Amazon rainforest. Cattle ranching is responsible for more than half of forest loss in the region.
(03/12/2007) A new study using NASA satellite images found evidence of seasonality in the Amazon rainforest. The results, published in the March 20 issue of the Proceedings of the National Academy of Sciences, show that the Amazon had 25 percent more leaf coverage in the dry season and 25 percent less in the rainy season.
(03/07/2007) Tropical rainforests are declining across most of the world. Since the close of the 1990s deforestation rates have only accelerated as growing levels of consumption and consistent population growth paint an increasingly bleak future for the world's forests and their resident biodiversity. These trends make it easy to lose hope. As such, stories that show local people earning a livelihood from biodiversity conservation are an inspiration.
(03/06/2007) Informal gold mining is causing environmental harm and human rights abuses in Guyana says a new report from the International Human Rights Clinic (IHRC) of Harvard Law School's Human Rights Program. Wildcat gold mining has been a serious problem in the Guiana shield countries of Brazil, Venezuela, Guyana, Suriname and French Guiana. Rising gold prices in recent years have only worsened the problem, as illegal miners have flooded the region clearing forest, polluting rivers, and making threats against indigenous people.
(03/06/2007) Much of the Amazon rainforest was not heavily populated by pre-Colombian indigenous cultures argues a new paper published in the journal Philosophical Transactions of the Royal Society B: Biological Sciences. The work challenges an increasingly accepted theory -- popularized in Charles C. Mann's 1491: 'New Revelations of the Americas Before Columbus' -- the Amazon supported dense, sedentary populations prior to the arrival of Europeans.
(02/28/2007) Indigenous populations used fire to clear large areas of tropical forest well before the arrival of Europeans reports a new study published in Annals of the Missouri Botanical Garden. The research has important implications for understanding the impact of present forest development on biodiversity and forest regeneration in the tropics.
(02/28/2007) Tuesday the Brazilian government announced the release of a series of scientific studies, including one by the national space agency (INPE) that projects a 4 to 8 degree-Celcius rise in temperatures in the Amazon Basin by 2100 if nothing is done to combat global climate change.
(02/23/2007) The International Tropical Timber Organization (ITTO) reports the Brazilian government plans to allow large-scale monitored harvesting of the Amazon rainforest. The new plan expands on an initiative proposed last year by Brazilian president Luiz Inacio Lula da Silva that would allow sustainable logging across 3 percent of the Amazon rain forest.
(02/18/2007) Peru's largest glacier is melting rapidly and could complete disappear by 2012 says a glaciologist from Ohio State University. Speaking at the annual meeting of the American Association for the Advancement of Science in San Francisco last week, Dr. Lonnie Thompson said that Peru's Qori Kalis glacier is melting at a rate of some 60 meters (200 feet) per year. Qori Kalis glacier is part of the Quelccaya Ice Cap, the largest body of ice in the tropics.
(02/15/2007) Growing timber exports and rising interest in biofuels are raising concerns that deforestation could accelerate in the South American country of Guyana. Guyana is a small, lightly populated country on the north coast of South America. About three-quarters of Guyana is forested, roughly 60 percent of which is classified as primary forest. Guyana's forests are highly diverse: the country has some 1,263 known species of amphibians, birds, mammals, and reptiles, and 6,409 species of plants.
(02/08/2007) Human disturbance of the Amazon rainforest is more extensive than previously thought say a team of scientists writing in the current edition of the journal Frontiers in Ecology. Reviewing recent research on the Amazon ecosystem, they note that human activities are affecting the health of the forest and impacting the ecological goods and services the Amazon provides mankind.
(02/06/2007) In recent years, scientists have warned of a looming biodiversity extinction crisis, one that will rival or exceed the five historic mass extinctions that occurred millions of years ago. Unlike these past extinctions, which were variously the result of catastrophic climate change, extraterrestrial collisions, atmospheric poisoning, and hyperactive volcanism, the current extinction event is one of our own making, fueled mainly by habitat destruction and, to a lesser extent, over-exploitation of certain species. While few scientists doubt species extinction is occurring, the degree to which it will occur in the future has long been subject of debate in conservation literature. Looking solely at species loss resulting from tropical deforestation, some researchers have forecast extinction rates as high as 75 percent. Now a new paper, published in Biotropica, argues that the most dire of these projections may be overstated. Using models that show lower rates of forest loss based on slowing population growth and other factors, Joseph Wright from the Smithsonian Tropical Research Institute in Panama and Helene Muller-Landau from the University of Minnesota say that species loss may be more moderate than the commonly cited figures. While some scientists have criticized their work as "overly optimistic," prominent biologists say that their research has ignited an important discussion and raises fundamental questions about future conservation priorities and research efforts. This could ultimately result in more effective strategies for conserving biological diversity, they say.
(02/06/2007) Reuters reports that Brazilian President Luiz Inacio Lula da Silva criticized wealthy countries for their contributions to global warming and told them to stay out of Brazil's business when it comes to the fate of the Amazon rainforest.
(01/26/2007) Brazil's National Statistics Office (IBGE) released a set of maps showing how farmers are converting the Amazon rainforest into cattle pasture and soybean farms. The maps show for the first time the impact of deforestation and agricultural expansion on the Amazon rainforest, according to the agency.
(01/24/2007) Two previously unknown species of lizard that are said to resemble miniature ground-dwelling dragons have been found in the threatened cerrado region of Brazil. The species, Stenocercus squarrosus and Stenocercus quinarius are described in the current issue of the South American Journal of Herpetology.
(01/24/2007) Scientists have discovered a previously unknown species of arboreal rodent in the cloud forests of Peru. The species, named Isothrix barbarabrownae, is described in the current issue of Mastozoologia, the principal mammalogy journal of South America.
(12/20/2006) A lot of rainforest conservation initiatives embrace sustainably harvested non-timber forest products (NTFPs) like seeds and nuts as a means to provide income to locals without harming the forest. Operating on the premise that such products are eco-friendly, hundreds of outfits ranging from Whole Foods to the Body Shop to Ben & Jerry's Homemade Ice Cream tout their use of sustainably harvested Brazil nuts and related products. But really, how sustainable are these products?
(12/19/2006) Understanding relationships between plants and animals is key to understanding rainforest ecology. Dr. Pierre-Michel Forget of the Museum National d'Histoire Naturelle in France is a renowned expert on the interdependency between rainforest trees and seed disperses. Author of dozens of papers on tropical forest ecology, Dr Forget is increasingly concerned about deforestation and biodiversity loss in forests of the Guiana Shield region of Northern South America. In particular he sees the invasion of informal gold miners, known as garimpeiros, as a significant threat to forests in French Guiana, Suriname, Guyana and Venezuela.
(12/19/2006) As Europe frets over climate change and deforestation, threats to "Europe's largest tropical rainforest" are mounting, according to reports from French Guiana. While French Guiana is best known for its infamous Devil's Island penal colony and as the main launch site for the European Space Agency, which is responsible for more than 50% of the state's economy activity, most of the territory is covered with lowland tropical rainforest. French Guiana's forests are biologically rich with some 1,064 known species of amphibians, birds, mammals and reptiles, and 5,625 species of vascular plants according to figures from the World conservation Monitoring Center.
(12/12/2006) Last Monday, Brazil created the world's largest rainforest protected area in the northern Amazon. Covering more than 15 million hectares (57,915 square miles) -- or an area larger than England -- the network of seven new protected reserves has been met with praise by environmental groups. Instrumental in the development of the conservation project has been an organization that most people wouldn't associate with rainforest conservation but certainly should: the Gordon and Betty Moore Foundation.
(11/27/2006) Forest fragmentation is rapidly eroding biodiversity in the Amazon rainforest and could worsen global warming according to research to be published this week in the journal Proceedings of the National Academy of Sciences. "Rainforest trees can live for centuries, even millennia, so none of us expected things to change too fast. But in just two decades-a wink of time for a thousand year-old tree-the ecosystem has been seriously degraded." said Dr. William Laurance, a scientist at the Smithsonian Tropical Research Institute in Panama and leader of the international team of scientists that conducted the research.
(11/09/2006) Troubles are mounting in one of Earth's most beautiful landscapes. Deep in the Venezuelan Amazon, among ancient forested tabletop mountains known as tepuis, crystalline rivers, and breathtaking waterfalls, illegal gold miners are threatening one of world's largest remaining blocks of wilderness, one that is home to indigenous people and strikingly high levels of biological diversity. As the situation worsens -- a series of attacks have counted both miners and indigenous people as victims -- a leading scientific organization has called for the Venezuelan government to take action.
(10/31/2006) Tropical rainforests house hundreds of thousands of species of plants, many of which hold promise for their compounds which can be used to ward off pests and fight human disease. No one understands the secrets of these plants better than indigenous shamans -medicine men and women - who have developed boundless knowledge of this library of flora for curing everything from foot rot to diabetes. But like the forests themselves, the knowledge of these botanical wizards is fast-disappearing due to deforestation and profound cultural transformation among younger generations. The combined loss of this knowledge and these forests irreplaceably impoverishes the world of cultural and biological diversity. Dr. Mark Plotkin, President of the non-profit Amazon conservation Team, is working to stop this fate by partnering with indigenous people to conserve biodiversity, health, and culture in South American rainforests. Plotkin, a renowned ethnobotanist and accomplished author (Tales of a Shaman's Apprentice, Medicine Quest) who was named one of Time Magazine's environmental "Hero for the Planet," has spent parts of the past 25 years living and working with shamans in Latin America. Through his experiences, Plotkin has concluded that conservation and the well-being of indigenous people are intrinsically linked -- in forests inhabited by indigenous populations, you can't have one without the other. Plotkin believes that existing conservation initiatives would be better-served by having more integration between indigenous populations and other forest preservation efforts.
(10/23/2006) For the Amazon, there is an immense threat looming on the horizon: climate change could well cause most of the Amazon rainforest to disappear by the end of the century. Dr. Philip Fearnside, a Research Professor at the National Institute for Research in the Amazon in Manaus, Brazil and one of the most cited scientists on the subject of climate change, understands the threat well. Having spent more than 30 years in Brazil and now recognized as one of the world's foremost experts on the Amazon rainforest, Fearnside is working to do nothing less than to save this remarkable ecosystem. Fearnside believes saving the Amazon will require a fundamental shift in perception where the Amazon is recognized as an asset beyond the current price of mahogany, soybeans, or cattle, where its value is only unlocked by its destruction. The Amazon is far worth more than this he says. It can play a key role in fighting climate change while providing economic sustenance for millions through sustainable agriculture and rational utilization of its renewable products. It can serve as a storehouse for biodiversity while at the same time ensuring reliable water supplies and moderating regional temperature and precipitation. In short, maintaining the Amazon as a viable ecosystem makes sense economically and ecologically -- it is in our best interest to preserve this resource while we still can.
(10/17/2006) The world's tropical rainforests are in trouble. Spurred by a global commodity boom and continuing poverty in some of the world's poorest regions, deforestation rates have increased since the close of the 1990s. The usual threats to forests -- agricultural conversion, wildlife poaching, uncontrolled logging, and road construction -- could soon be rivaled, and even exceeded, by climate change and rising levels of carbon dioxide in the atmosphere. Understanding these threats is key to preserving forests and their ecological services for current and future generations. William F. Laurance, a distinguished scholar and president of the Association for Tropical Biology and conservation (ATBC) -- the world's largest scientific organization dedicated to the study and conservation of tropical ecosystems, is at the forefront of this effort.
