Ground-breaking Amazon rainforest imagery will help monitor deforestation
(11/27/2007) Scientists have developed a ground-breaking high resolution snapshot of 400,000 square kilometers of Amazon rainforest. The work will help researchers remotely monitor deforestation, according to the Woods Hole Research Center (WHRC).


Amazon rainforest children to get medicinal plant training from shamans
(11/21/2007) The Amazon conservation Team (ACT) -- a group using innovative approaches to preserving culture and improving health among Amazonian rainforest tribes -- has been awarded a $100,000 grant from Nature's Path, an organic cereal manufacturer. The funds will allow ACT to address one of the most pressing social concerns for Amazon forest dwellers by expanding its educational and cultural "Shamans and Apprentice" program for indigenous children in the region.


Large-scale agriculture 'compromises' forest's ability to recover
(11/19/2007) As deforestation of tropical forests continues unhindered, one of the future hopes for these damaged ecosystems is regeneration in secondary forests. Some areas that were once slash-and-burned for cattle ranching or subsistence agriculture have been abandoned, allowing scientists to study the possibility of recovery in the rainforest. If anyone has a clear idea of the potential of secondary forests it is Robin L. Chazdon. Dr. Chazdon, a full professor of Ecology and Evolutionary Biology at the University of Connecticut, has been studying the regeneration of secondary forest for over twenty-five years. She has published over 50 papers on tropical ecology, currently she serves as an active member of the Biotropica editorial board and is a member of the Bosques Project, which measures secondary forest recovery in Northern Costa Rica.


Physicists join fight to save amphibians from extinction
(11/19/2007) Physicists have joined the fight to save amphibians from extinction by using Optical Coherence Tomography (OCT) to investigate the properties of frogs skin.


Only 150 vaquita remain
(11/19/2007) Only 150 individual vaquita, the world's smallest cetacean, remain, according to a new study published in conservation Biology. The species has been decimated as accidental bycatch in fishing nets in its Gulf of California habitat. Researchers--who say there may be only a two-year window to save the species from extinction--have launched a last-ditch conservation effort.


Whale stranded 1,000 miles up the Amazon river
(11/17/2007) An 18-foot minke whale was found beached on a sandbar 1,000 miles up a tributary of the Amazon river, reported Globo television and the Associated Press.


In the Amazon, primary forest biodiversity tops that of secondary forest, plantations
(11/12/2007) Plantations and secondary forests are no match for primary Amazon rainforest in terms of biodiversity, reports the largest ever assessment of the biodiversity conservation value in the tropics.


Subtle threats could ruin the Amazon rainforest
(11/7/2007) While the mention of Amazon destruction usually conjures up images of vast stretches of felled and burned rainforest trees, cattle ranches, and vast soybean farms, some of the biggest threats to the Amazon rainforest are barely perceptible from above. Selective logging -- which opens up the forest canopy and allows winds and sunlight to dry leaf litter on the forest floor -- and 6-inch high "surface" fires are turning parts of the Amazon into a tinderbox, putting the world's largest rainforest at risk of ever-more severe forest fires. At the same time, market-driven hunting is impoverishing some areas of seed dispersers and predators, making it more difficult for forests to recover. Climate change -- an its forecast impacts on the Amazon basin -- further looms large over the horizon.


Proposed gold mine proves controversial in French Guiana rainforest
(11/7/2007) Commercial gold mining threatens a key forest reserve and wetland in French Guiana say scientists who warn that exploitation could pollute rivers with toxic compounds, threaten wildlife, and put indigenous populations at risk.

Amphibian extinction may be worse than thought
(10/31/2007) Amphibian extinction rates may be higher than previously thought, according to new DNA analysis that found more than 60 unrecognized species in the Guiana Shield of South America.


Iguanas listen to birds to avoid predators
(10/29/2007) As the world's only sea-feeding lizard, Galapagos Marine Iguanas have long held a unique place in the animal kingdom. While most of their life is spent on land, these lizards forage the seas for their staple food: algae. Now, new research has provided this species with another distinction: although the Galapagos Marine Iguana is mute, it recognizes and utilizes the alarm call of the Galapagos Mockingbird. This is the first instance of a non-vocal species eavesdropping on another species' calls. Both the iguana and mockingbird fall prey to the Galapagos hawk, so by recognizing the mockingbird's warning the iguanas gain important information on avoiding predation.


2007 Amazon fires among worst ever
(10/22/2007) By some measures, forest fires in the Amazon are at near-record levels, according to analysis Brazilian satellite data by mongabay.com. A surge in soy and cattle prices may be contributing to an increase in deforestation since last year. Last year environmentalists and the Brazilian government heralded a sharp fall in deforestation rates, the third consecutive annual decline after a peak in 2004. Forest loss in the 2006-2007 season was the lowest since record-keeping began in the late in 1970s. While the government tried to claim credit for the drop, analysts at the time said that commodity prices were a more likely driver of slow down: both cattle and soy prices had declined significantly over the previous months.


Uncontacted Amazon tribe spotted by plane in Peru
(10/21/2007) A group of uncontacted indigenous tribesmen were spotted by plane in a remote part of the Peruvian Amazon last month, according to Survival International. The region is threatened by illegal mahogany loggers.


Brazil to search for oil in the Amazon
(10/21/2007) Brazil's plan to seek oil in the Western Amazon has upset environmentalists, reports the Associated Press (AP). The National Petroleum Agency, or ANP, plans to put US$36 million toward oil and gas exploration in Acre, a state bordering Bolivia, according to Brazilian state media Agencia Brasil, but environmental officials say no impact study has been done to assess how the plan could affect the Amazon.


Amazon plant diversity still a mystery
(10/21/2007) The Amazon is one of the few places on the earth that still evokes an accurate sense of mystery. While the Taiga, Antarctica, and Sahara may compare to the Amazon in wilderness size, none hold the same mystique of unknown species. It is believed that one third of the world's species inhabits this tropical rainforest. The only region comparable in mystery (though not in species) may be the world's oceans.


Costa Rica gets $26M debt-for-nature swap
(10/18/2007) Under an agreement signed Wednesday by the governments of the United States and environmental groups, $26 million of Costa Rican debt will be forgiven in exchange for tropical forest conservation. The debt-for-nature swap comes under the Tropical Forest conservation Act of 1998, legislation intended to allow eligible developing countries to forego paying back debt owed to the U.S. in exchange for supporting local tropical forest conservation activities.


Is the Amazon more valuable for carbon offsets than cattle or soy?
(10/17/2007) After a steep drop in deforestation rates since 2004, widespread fires in the Brazilian Amazon (September and October 2007) suggest that forest clearing may increase this year. All told, since 2000 Brazil has lost more than 60,000 square miles (150,000 square kilometers) of rainforest -- an area larger than the state of Georgia or the country of Bangladesh. Most of this destruction has been driven by clearing for cattle pasture and agriculture, often in association with infrastructure development and improvements. Higher commodity prices, especially for beef and soy, have further spurred forest conversion in the region. While drivers of Amazon deforestation are stronger than ever, mounting concerns over climate change and the effort to reign in greenhouse gas emissions may provide new economic incentives for landowners to preserve forest lands through a concept known as "avoided deforestation".


Amazon rainforest burning "worst" in memory
(10/16/2007) Fires continue to rage in the Amazon, according to local reports. John Cain Carter, a rancher who runs Alianca da Terra, an environmental accountability group for agricultural operators, says that the fires are the worst he has ever seen in the region. "I have never seen fires this bad," he told mongabay.com. "The fires are even worse than in 1998's El Nino event." NASA satellite images released at the end of September confirm widespread burning in the Amazon state of Mato Grosso.


South American development plan could destroy the Amazon

Do Costa Rica's payments for environmental services work?
(9/17/2007) While Costa Rica is now known as a world leader for conservation policies and ecotourism, the Central American country had some of the world's highest deforestation rates prior to establishing its reputation. Clearing for cattle pasture and agriculture destroyed much of the country's biodiverse rainforests in the 1960s and 1970s.


China urged to join sustainable soy efforts in the Amazon
(9/12/2007) Brazilian soy crushers have urged China to join an alliance to promote sustainable soybean production in the Amazon, according to Reuters. Brazil, soon to be the world's largest producer of soybeans, recently formed the Global Roundtable on Responsible Soy Association as concerns grow that global demand for biofuels will level the Amazon rainforest. Environmentalists say demand from China is playing an important role in surging soybean production in the region.

Brazil's threatened Atlantic forest may be more resilient than thought
(9/6/2007) The Atlantic forest of Brazil, one of the world's most threatened biodiversity hotspots, may have served as a critical refuge for biodiversity during the ice ages. The findings suggest that despite being reduced to just 8 percent of its original extent due to agriculture and urban expansion, the Atlantic forest may be capable of recovery. In other words, the Atlantic forest may be more resilient to change than previously believed.


Tree resprouting offers hope in former pastures of Brazil's cerrado
(9/6/2007) Deforested landscapes in the Brazilian cerrado show hopeful signs of recovery even after long periods of intensive use, reports a study published in the journal Biotropica. Analyzing the natural reestablishment of native trees in former pastureland located in the dry woodlands of the Brazilian cerrado, a team of researchers found that while species richness was lower in older pasture, density and composition of regenerating trees did not change with pasture age.


Can remittances and globalization help the environment?
(9/5/2007) Globalization and other economic trends appear to be helping the degraded forests of El Salvador recover, reports new research that evaluated the impact of global trade, land policy changes, and remittances on forest cover. The study, by Susanna B. Hecht of University of California at Los Angeles and Sassan S. Saatchi of the California Institute of Technology, used socioeconomic data, land-use surveys, and satellite imagery to document significant increases in the area of El Salvador covered by both light woodlands and forest since peace accords were signed in the warn-torn country in 1992.

Land reform agency sanctions logging in Amazon rainforest park
(8/21/2007) Under the guise of a sustainable development scheme, a Brazilian land agency has granted large tracts of Amazon rainforest to colonists who quickly resold the forest to loggers, alleges a new report from Greenpeace. Some of the concessions were in the Amazon National Park, a national park.


Biofuels driving destruction of Brazilian cerrado
(8/21/2007) The cerrado, wooded grassland in Brazil that once covered an area half the size of Europe, is fast being transformed into croplands to meet rising demand for soybeans, sugarcane, and cattle. The cerrado is now disappearing more than twice as the rate as the neighboring Amazon rainforest, according to a Brazilian expert on the savanna ecosystem.


Crop domestication originated in compost piles
(8/19/2007) New research lends support to the theory that backyard gardens and refuse heaps played an important role in early crop domestication.


Clearing rainforest for cattle pasture drives surge in vampires
(8/15/2007) A new study confirms that vampire bats are thriving due to the clearing of rainforest for cattle pasture in Costa Rica. Instead of having to seek out scarce wildlife in the forest, vampire bats now prey on cattle kept in high densities on ranches.


Amazon deforestation in Brazil falls 29% for 2007
(8/13/2007) Deforestation in the Brazilian Amazon fell 29 percent for the 2006-2007 year, compared with the prior period. The loss of 3,863 square miles (10,010 square kilometers) of rainforest was the lowest since the Brazilian government started tracking deforestation on a yearly basis in 1988.

"Virgin" rain forests of Costa Rica a misnomer
(7/25/2007) Radiocarbon dating of montane forest soils in Costa Rica uncovered evidence of charcoal that shows its otherwise "virgin" tropical forests are less than 200 years old. The findings, published in the journal Biotropica, have implications for the re-establishment of rain forests after clearing.


Longest-running Amazon rainforest experiment imperiled by colonization
(7/25/2007) One of the world's most important and longest-running scientific experiments is under threat by new colonization proposed by the Brazilian government, warn researchers writing in the journal Nature. The Biological Dynamics of Forest Fragments Project, an experiment launched outside the Brazilian city of Manaus more than 25 years, has helped researchers understand the impacts of deforestation and fragmentation on the complex ecology of the world's largest and most biodiverse rainforest: the Amazon. But now a colonization scheme sanctioned by the Brazilian federal agency SUFRAMA threatens to undermine the basis for decades of critical research.
