News articles on Amazon rainforest
Mongabay.com news articles on Amazon rainforest in blog format. Updated regularly.
(09/26/2011) The Amazon rainforest can recover fromlogging, but has a far more difficult time returning after repeated burning, reports a new study in mongabay.com's open-access journal Tropical Conservation Science. In areas where the Amazon had been turned to pasture and was subject to repeated burning, Visima trees become the dominant tree inhibiting the return of a biodiverse forest. The key to the sudden domination of Visima trees, according to the study, is that these species re-sprout readily following fires; a capacity most other Amazonian trees lack.
New map reveals the most biodiverse place on Earth, but already threatened by oil
(09/22/2011) A new map highlights the importance of conserving Yasuni National Park as the most biodiverse ecosystem in the Western Hemisphere, and maybe even on Earth. Scientists released the map to coincide with the United National General Assembly in support of a first-of-its-kind initiative to save the park from oil exploration through international donations to offset revenue loss. Known as the Yasuni-ITT Initiative, the plan, if successful, would protect a 200,000 hectare bloc in Yasuni National Park from oil drilling in return for a trust fund of over $3 billion.
Indigenous people blockade river against 'murderous' oil company
(09/21/2011) Over the weekend more than 100 Shuar indigenous people, also known as Wampis, blockaded the Morona River in Peru in an effort to stop exploratory oil drilling by Canadian-owned Talisman Energy. The blockade in meant to prevent oil drilling in an area of the Peruvian Amazon known as Block 64, home to four indigenous tribes in total and the Pastaza River Wetland Complex, a Ramsar wetland site.
Two arrested in connection with murdering Amazon activists
(09/20/2011) Two suspects have been arrested for allegedly taking part in the killing of Amazon activist, José Cláudio Ribeiro da Silva, and his wife, Maria do Espírito Santo da Silva. The men, who are brothers, were arrested after police stormed their remote jungle camp on Sunday in Brazilian state of Para. A third man remains at large.
Loving the tapir: pioneering conservation for South America's biggest animal
(09/11/2011) Compared to some of South America's megafauna stand-out species—the jaguar, the anaconda, and the harpy eagle come to mind—the tapir doesn't get a lot of love. This is a shame. For one thing, they're the largest terrestrial animal on the South American continent: pound-for-pound they beat both the jaguar and the llama. For another they play a very significant role in their ecosystem: they disperse seeds, modify habitats, and are periodic prey to big predators. For another, modern tapirs are some of the last survivors of a megafauna family that roamed much of the northern hemisphere, including North America, and only declined during the Pleistocene extinction. Finally, for anyone fortunate enough to have witnessed the often-shy tapir in the wild, one knows there is something mystical and ancient about these admittedly strange-looking beasts.
Peru president signs indigenous rights act into law
(09/07/2011) Peru's new president, Ollanta Humala, has signed into law a measure requiring that indigenous groups are consulted prior to any mining, logging, or oil and gas projects on their land. If properly enforced, the new legislation will give indigenous people free, prior and informed consent (FPIC) over such industrial projects, though the new law does not go so far as to allow local communities a veto over projects. Still, the law puts Peru in line with the Indigenous and Tribal Peoples Convention of 1989, which the South American nation ratified nearly two decades ago.
Cute animal picture of the day: baby Bolivian gray titi monkey
(09/07/2011) The Bolivian gray titi monkey (Callicebus donacophilus) is found in a small area of the Amazon in Bolivia and Brazil.
Photo: new titi monkey discovered in Amazon area under siege
(08/25/2011) A new species of titi monkey has been discovered in the Brazilian Amazon. Found during a 2010 December expedition, this is the second new titi monkey discovered in the Amazon in three years. In 2008 another new titi, dubbed the Caquetá titi, was discovered in the Colombian Amazon, although it was only announced last year. An expedition backed by WWF-Brazil found the new titi between the Guariba River and the Roosevelt River in northwestern part of Mato Grosso, a state of Brazil known as a center of Amazon destruction.
Indigenous protestors embark on 300-mile walk to protest Amazon road in Bolivia
(08/21/2011) Indigenous protesters are targeting a new road in the Bolivian Amazon, reports the BBC. The 190-mile highway under construction in the Bolivian Amazon will pass through the Isiboro-Secure Indigenous Territory and National Park (Tipnis), a 4,600-square mile (11,900 square kilometers) preserve which boasts exceptional levels of rainforest biodiversity, including endangered blue macaws and fresh-water dolphins. Indigenous peoples who live in Tipnis are participating in a month-long protest march against the road, which they claim violates their right to self-governance.
Lessons from the world's longest study of rainforest fragments
(08/15/2011) For over 30 years, hundreds of scientists have scoured eleven forest fragments in the Amazon seeking answers to big questions: how do forest fragments' species and microclimate differ from their intact relatives? Will rainforest fragments provide a safe haven for imperiled species or are they last stand for the living dead? Should conservation focus on saving forest fragments or is it more important to focus the fight on big tropical landscapes? Are forest fragments capable of regrowth and expansion? Can a forest—once cut-off—heal itself? Such questions are increasingly important as forest fragments—patches of forest that are separated from larger forest landscapes due to expanding agriculture, pasture, or fire—increase worldwide along with the human footprint.
Indigenous peoples in Suriname still wait for land rights
(07/31/2011) Legal rights and recognition for the diverse indigenous peoples of Suriname have lagged behind those in other South American countries. Despite pressure from the UN and binding judgments by the Inter-American Court of Human Rights, Suriname has yet to recognize indigenous and tribal land rights, a situation that has disconnected local communities from decisions regarding the land they have inhabited for centuries and in some cases millennia. A new report, Securing Indigenous Peoples’ Rights in Conservation in Suriname: A Review outlines how this lack of rights has alienated indigenous communities from conservation efforts in Suriname. Instead of having an active say in the creation of conservation reserves, as well as their management, decisions on indigenous lands have traditionally been imposed from the 'top-down' either by government officials or NGOs.
Suspects named for assassination of husband and wife activists in Brazil
(07/21/2011) Brazilian authorities have fingered three men for the killing of environmental activist, José Cláudio Ribeiro da Silva, and his wife, Maria do Espírito Santo da Silva, in May. The grisly murders received international attention, since José da Silva was a well known activist against illegal logging in Pará, a state in Brazil that is rife with deforestation and violence.
Oil company hires indigenous people to clean up its Amazon spill with rags and buckets
(07/13/2011) On Sunday morning children swimming in the Mashiria River in the Peruvian Amazon noticed oil floating on the water. A pipeline owned by Maple Energy had ruptured in Block 31-E, polluting the Mashiria River which is used by the Shipibo indigenous community in Nuevo Sucre for fishing and drinking water. In response to the spill, Maple Energy's local operator—Dublin incorporate transnational—hired 32 Shipibo community members to clean up the spills using only rags and buckets.
Peru cancels massive dam project after years of protests
(06/16/2011) Three years of sustained community opposition have brought down plans for a massive dam on the Madre de Dios River in Peru. Yesterday the Peruvian government announced it was terminating the contract with Empresa de Generación Eléctrica Amazonas Sur (Egasur) to build a 1.5 gigawatt dam, known as the Inambari Dam. The dam was one of six that were agreed upon between Peru and Brazil to supply the latter with energy.
Last chance to see: the Amazon's Xingu River
(06/15/2011) Not far from where the great Amazon River drains into the Atlantic, it splits off into a wide tributary, at first a fat vertical lake that, when viewed from satellite, eventually slims down to a wild scrawl through the dark green of the Amazon. In all, this tributary races almost completely southward through the Brazilian Amazon for 1,230 miles (1,979 kilometers)—nearly as long as the Colorado River—until it peters out in the savannah of Mato Grosso. Called home by diverse indigenous tribes and unique species, this is the Xingu River.
Germany backs out of Yasuni deal
(06/13/2011) Germany has backed out of a pledge to commit $50 million a year to Ecuador's Yasuni ITT Initiative, reports Science Insider. The move by Germany potentially upsets an innovative program hailed by environmentalists and scientists alike. This one-of-a-kind initiative would protect a 200,000 hectare bloc in Yasuni National Park from oil drilling in return for a trust fund of $3.6 billion, or about half the market value of the nearly billion barrels of oil lying underneath the area. The plan is meant to mitigate climate change, protect biodiversity, and safeguard the rights of indigenous people.
Shareholders to Chevron: company showing 'poor judgment' in Ecuador oil spill case
(05/26/2011) After being found guilty in February of environmental harm and ordered to pay $8.6 billion in an Ecuador court of law, Chevron this week faced another trial: this time by shareholders in its Annual General Meeting in California. While Chevron has appealed the Ecuador case and a US court has put an injunction barring the enforcement of the ruling in the US, notable Chevron investors say the company has gone astray in its seemingly endless legal battle with indigenous groups in the Ecuadorian Amazon.
Killing in the name of deforestation: Amazon activist and wife assassinated
(05/24/2011) José Cláudio Ribeiro da Silva and his wife, Maria do Espírito Santo da Silva, were gunned down last night in an ambush near their home in the Brazilian state of Pará. Da Silva was known as a community leader and an outspoken critic of deforestation in the region. Police believe the da Silvas were killed by hired assassins because both victims had an ear cut off, which is a common token for hired gunmen to prove their victims had been slain, according to local police investigator, Marcos Augusto Cruz, who spoke to Al Jazeera. Suspicion immediately fell on illegal loggers linked to the charcoal trade that supplies pig iron smelters in the region.
Authorities launch stealth operation in Amazon after satellite images reveal deforestation
(05/24/2011) Brazil’s environmental enforcement agency busted an illegal logging ring following analysis of satellite imagery, reports Globo.
Uncovering the private lives of Amazon wildlife through camera traps
(05/20/2011) One of the best words to describe Amazon wildlife, including large mammals and birds, is cryptic. A person can spend a day trekking through the dense green and brown foliage of the Amazon and see nothing more than a few insects, maybe a frog here and there if they have good eyes. In fact, researchers have spent years in the jungle and never seen a jaguar, let alone a tapir. Some species like the bushdog and the giant armadillo are even more cryptic. Almost never encountered by people, in some parts of the Amazon they have taken on a mythic status, more rumor around the fire than reality. However, camera traps—automated cameras that take a flash photo whenever an animal triggers an infrared sensor—in the Amazon have begun to reveal long-sought information about the presence and abundance of species, providing new data on range and territories. And even at times giving glimpses into the private lives of species that remain largely shrouded in mystery.
ConocoPhillips withdraws from oil exploitation in uncontacted indigenous territory
(05/11/2011) ConocoPhillips has announced it is withdrawing from its 45% share of oil drilling in Block 39 of Peru's Amazon rainforest. The withdrawal comes after pressure from indigenous-rights and environmental groups to leave two Peruvian oil blocks—39 and 67—alone, due to the presence of indigenous people who have chosen to remain uncontacted. ConocoPhillips and other companies have been warned they will 'decimate' tribes if they remain. However, Spanish oil company Repsol-YPF still operates in block 39 and is currently doing seismic testing for oil reserves in the untouched region. ConocoPhillips has not divulged what company is taking their place.
Controversial Brazilian mega-dam receives investment of $1.4 billion
(05/02/2011) Brazil's most controversial mega-dam, Belo Monte, which is moving full steam ahead against massive opposition, has received an extra infusion of cash from Vale, a Brazilian-run mining company.
Demand for gold pushing deforestation in Peruvian Amazon
(04/19/2011) Deforestation is on the rise in Peru's Madre de Dios region from illegal, small-scale, and dangerous gold mining. In some areas forest loss has increased up to six times. But the loss of forest is only the beginning; the unregulated mining is likely leaching mercury into the air, soil, and water, contaminating the region and imperiling its people. Using satellite imagery from NASA, researchers were able to follow rising deforestation due to artisanal gold mining in Peru. According the study, published in PLoS ONE, Two large mining sites saw the loss of 7,000 hectares of forest (15,200 acres)—an area larger than Bermuda—between 2003 and 2009.
NASA image reveals extent of 2010 Amazon drought
(04/17/2011) NASA has revealed a satellite image of the crippling effect of last year's record-breaking drought on the Amazon ecosystem. For those of you counting, that's two record droughts in the Amazon Basin in 5 years.
Giant fish help grow the Amazon rainforest
(04/12/2011) A fruit in the flooded Amazon falls from a tree and plops in the water. Before it can even sink to the floor, a 60-pound monster fish with a voracious appetite gobbles it. Nearly a week later—and miles away—the fish expels its waste, including seeds from the fruit eaten long ago and far away. One fortunate seed floats to a particularly suitable spot and germinates. Many years later the new fruit tree is thriving, while the same monster-fish returns from time-to-time, waiting for another meal to drop from the sky. This process is known as seed-dispersal, and while researchers have studied the seed-dispersal capacity of such species as birds, bats, monkeys, and rodents, one type of animal is often overlooked: fish.
Indigenous group claims Ecuadorian government complicit in 'genocide'
(04/06/2011) Ecuador's paramount indigenous organization has filed a legal complaint against the government, including President Rafael Correa, for allegedly participating in 'genocide' against indigenous people in the Amazon. The Confederation of Indigenous Nationalities of Ecuador (CONAIE) is arguing that expanding oil exploration and mining is imperiling the lives of uncontacted tribes that have chosen voluntary isolation known as the Tagaeri and the Tarmenane, reports the AFP.
'Luck and perseverance': new plant genus discovered in Amazon
(03/31/2011) The discovery of a new plant species is not uncommon, especially in places of remarkable biodiversity such as the Amazon rainforest. However, discovering a new plant genus, a taxonomic rank above species, is, according to Henk van der Werff fromt the Missouri Botanical Garden (MBG), "a matter of luck and perseverance". Researchers with the Missouri Botanical Garden have been blessed with both as they have announced two new species of Amazonian plants, one from Ecuador and one from Peru, that comprise a completely new genus: named, Yasunia, since the plant was originally discovered in Ecuador's vast Yasuni National Park.
Last year's drought hit Amazon hard: nearly a million square miles impacted
(03/29/2011) A new study on its way to being published shows that the Amazon rainforest suffered greatly from last year's drought. Employing satellite data and supercomputing technology, researchers have found that the Amazon was likely hit harder by last year's drought than a recent severe drought from 2005. The droughts have supported predictions by the Intergovernmental Panel on Climate Change's (IPCC) that climate change, among other impacts, could push portions of the Amazon to grasslands, devastating the world's greatest rainforest. "The greenness levels of Amazonian vegetation—a measure of its health—decreased dramatically over an area more than three and one-half times the size of Texas and did not recover to normal levels, even after the drought ended in late October 2010," explains the study's lead author Liang Xu of Boston University.
Amazon still neglected by researchers
(03/28/2011) Although the Amazon is the world's largest tropical forest, it is not the most well known. Given the difficulty of access along with the fear of disease, dangerous species, indigenous groups, among other perceived perils, this great treasure chest of biology and ecology was practically ignored by scientists for centuries. Over the past few decades that trend has changed, however even today the Amazon remains lesser known than the much smaller, and more secure, tropical forests of Central America. A new study in mongabay.com's open access journal Tropical Conservation Science, which surveyed two prominent international tropical ecology journals (Biotropica and Journal of Tropical Ecology) between 1995 and 2008, finds that Central America was the subject of twice as many studies as the Amazon. In fact, according to the authors, much of the Amazon remains terra incognito to researchers, even as every year more of the rainforest is lost to human impacts.
Leaf harvesting impacts Amazon palm
(03/28/2011) Overexploitation of wildlife doesn't just threaten animals such as bluefin tuna, pangolins, and parrots, but plants as well. Leaves from the carana or puy palm (Lepidocaryum tenue) are used for thatching buildings in the northwestern Amazon, however a recent study in mongabay.com's open access journal Tropical Conservation Science finds that the overharvesting could imperil a palm's ability to survive.
Bill Clinton takes on Brazil's megadams, James Cameron backs tribal groups
(03/28/2011) Former US President, Bill Clinton, spoke out against Brazil's megadams at the 2nd World Sustainability Forum, which was also attended by former California governor, Arnold Schwarzenegger, and film director, James Cameron, who has been an outspoken critic of the most famous of the controversial dams, the Belo Monte on the Xingu River.
Photos: two new freshwater stingrays discovered in the Amazon
(03/09/2011) Few people probably realize that in the rivers and lakes of the Amazon rainforest large stingrays glide, searching for crustaceans and small fish. Equipped with a powerful barbed tail they are often feared by locals. However, even as big as these fish are, new species continue to be described. Recently, scientists have identified two new species of Amazonian freshwater stingray near Iquitos, Peru. The new stingrays are unique enough to be placed in a new genus (the taxonomic level above species) called Heliotrygon, the first new Amazonian stingray genus to be described in nearly 25 years.
World's most controversial dam, Brazil's Belo Monte, back on
(03/06/2011) A recent injunction against controversial dam, Belo Monte, in Brazil has been overturned, allowing the first phase of construction to go ahead. The ruling by a higher court argued that not all environmental conditions must be met on the dam in order for construction to start.
Report: 90 oil spills in Peruvian Amazon over 3 years
(03/03/2011) A new report has uncovered 90 oil spills by Pluspetrol in northern Peru's Amazon rainforest over the past 3 years. Covering two oil blocs—1-AB and 8—the report, complied by the Federation of Indigenous Communities of the Corrientes River (FECONACO), recorded 18 major oil spills in just the last year. "A week after the landmark ruling against Chevron in Ecuador for $9 billion of damage from operations in the 1970's and 80's, this new report highlights the ongoing devastation caused by the oil industry on the fragile Amazon ecosystem and the people that live there," said Atossa Soltani, Executive Director at Amazon Watch, in a press release.
Indigenous leaders take fight over Amazon dams to Europe
(03/02/2011) Three indigenous Amazonian leaders spent this week touring Europe to raise awareness about the threat that a number of proposed monster dams pose to their people and the Amazon forest. Culminating in a press conference and protests in London, the international trip hopes to build pressure to stop three current hydroelectric projects, one in Peru, including six dams, and two in Brazil, the Madeira basin industrial complex and the massive Belo Monte dam. The indigenous leaders made the trip with the NGO Rainforest Foundation UK, including support from Amazon Watch, International Rivers, and Rainforest Concern.
Judge suspends Brazil's monster dam: contractor 'imposing' its interests
(02/27/2011) Construction on Brazil's planned mega-dam, the Belo Monte, has been ordered suspended by a federal judge, citing unmet environmental and social conditions. Just last month, the hugely controversial dam, was handed a partial license from Brazil's Environmental Agency (IBAMA). However, the judge, Ronaldo Destêrro, found that the partial license, the first of its kind in Brazil, was granted under pressure from the dam's contractor, Norte Energia or NESA.
First strike against illegal gold mining in Peru: military destroys miners' boats
(02/21/2011) Around a thousand Peruvian soldiers and police officers destroyed seven and seized thirteen boats used by illegal gold miners in the Peruvian Amazon, reports the AFP. The move is seen as a first strike against the environmentally destructive mining. Used to pump silt up from the river-bed, the boats are essential tools of the illegal gold mining trade which is booming in parts of the Amazon.
Chevron found guilty, ordered to pay $8.2 billion in epic oil contamination fight
(02/14/2011) It was the environmental legal battle that some believed would never end (and they may still be right). But today in Lago Agrio, Ecuador, after 18 years of an often-dramatic court case, Chevron was found guilty of environmental harm and ordered to pay $8.2 billion in damages, however the oil giant says it will appeal the ruling. The lawsuit was filed by indigenous groups in the Ecuadorian Amazon who argue that poor environmental safeguards from Texaco in the 1970s and 80s led to widespread oil contamination and high rates of diseases, including cancer, among the populace. In 2001 Chevron purchased Texaco and inherited the legal fight. For its part, Chevron has dubbed the ruling "illegitimate" and with an appeal will drag the case on longer.
Not enough data on world's tropical plants to predict impact of warming world
(02/14/2011) How many tropical plant species are threatened by climate change? Which plants have big enough ranges to survive a warming world, not to mention deforestation? How likely is it that the tropics are undergoing a current mass extinction? These questions may appear straight forward, but a new study in Global Change Biology finds that researchers lack the hard data necessary to come to any confident conclusions. According to the study, nine out of ten tropical plants from Africa, Asia, and South America lack the minimum number of collections needed (at least 20) to determine the species' range, and therefore predict the impact of climate change.
Vines rising in the Amazon and other American rainforests
(02/14/2011) For years tropical scientists have anecdotally reported an increase in vines in the Amazon and other American tropical forests, but now a number of studies have confirmed such reports: vines are on the rise in Neotropical rainforests.
Half a million people sign petition against Belo Monte, Brazilian mega-dam
(02/08/2011) In a protest today in Brasilia, Brazil, indigenous people delivered a petition to authorities signed by 500,000 people calling on them to cancel the controversial Belo Monte dam. They hope the petition, organized by online activist group Avaaz, will help convince Brazil's new president, Dilma Rousseff, to cancel the project. However, actions by Brazil's first female president have pushed the dam forward.
Chief financier of Belo Monte dam ties social and environmental requirements to controversial project
(02/04/2011) The Brazilian National Development Bank (BNDES) has announced it will not grant a $640 million loan for the hugely controversial Belo Monte dam until 40 social and environmental conditions are met. In response, the company contracted to build the dam, Norte Energia, S.A. (NESA), has stated it may drop the bank's loan altogether and seek less discriminating private funding to start construction. Last week the Brazilian government's environmental agency IBAMA announced that the dam had been granted a partial license, an aberration in Brazilian law, to jumpstart construction. But BNDES also says it will not hand out the loan until a full license is granted.
Two massive droughts evidence that climate change is 'playing Russian roulette' with Amazon
(02/03/2011) In 2005 the Amazon rainforest underwent a massive drought that was labeled a one-in-100 year event. The subsequent die-off of trees from the drought released 5 billion tons of CO2. Just five years later another major drought struck. The 2010 drought, which desiccated entire rivers, may have been even worse according to a new study in Science, adding on-the-ground evidence to fears that climate change may inevitably transform the world's greatest rainforest.
Paradise & Paradox: a semester in Ecuador
(02/02/2011) A semester abroad is an opportunity to live a sort of compacted life. In a few short months you seem to gain the experience of a much longer time and make enough memories to fill years. I recall a weeklong trip to the Alvord Desert with a field biology class from Portland Community College: the adventure of living out of a van, conducting research, and experiencing a place with classmates turned colleagues and professors turned friends who knew the desert like the backs of their hands. In that regard, it had a lot in common with my semester in Ecuador, but I can't think of anything that could have prepared me for a four month stay in a small South American country that I knew very little about.
Consumer goods industry announces goal of zero deforestation in Cancun
(11/30/2010) While governments continue to stall on action to cut greenhouse gas emissions worldwide, global corporations are promising big changes to tackle their responsibilities. The Board of Consumer Goods Forum (BCGF) has approved a resolution to achieve net zero deforestation by 2020 in products such as palm oil, soy, beef, and paper. Announced yesterday at the UN Climate Summit in Cancun, the BCGF has stated the goal will be met both by individual actions within companies and collective action, including partnerships with NGOs, development banks, and governments. With such giants as Walmart, Unilever, Carrefour, and General Mills, BCGF is made up of four hundred global consumer goods manufacturers and retailers totaling over $2.8 trillion in revenue.
Oil, indigenous people, and Ecuador's big idea
(11/23/2010) Ecuador's big idea—potentially Earth-rattling—goes something like this: the international community pays the small South American nation not to drill for nearly a billion barrels of oil in a massive block of Yasuni National Park. While Ecuador receives hundred of millions in an UN-backed fund, what does the international community receive? Arguably the world's most biodiverse rainforest is saved from oil extraction, two indigenous tribes' requests to be left uncontacted are respected, and some 400 million metric tons of CO2 is not emitted from burning the oil. In other words, the international community is being asked to put money where its mouth is on climate change, indigenous rights, and biodiversity loss. David Romo Vallejo, professor at the University of San Francisco Quito and co-director of Tiputini research station in Yasuni, recently told mongabay.com in an interview that this is "the best proposal so far made to ensure the protection of this incredible site."
50 NGOS tell big oil to get out of uncontacted natives' territory
(11/21/2010) A letter signed by over 50 NGOs is calling on three big oil companies—Perenco, Repsol-YPF, and ConocoPhillips—to withdraw from Peruvian territory inhabited by uncontacted indigenous tribes. The letter states that the oil companies' presence in the area threatens the uncontacted tribe with diseases, for which they have little immunity, and puts the lives of oil company workers in jeopardy, since past encounters have ended in violence.
Formal petition filed against Belo Monte dam
(11/11/2010) The struggle against Brazil's Belo Monte dam on the Xingu River continues as today indigenous groups sent a formal petition to the Inter-American Commission on Human Rights (IACHR) to suspend the dam's construction, stating the dam violates human rights. The dam, which has been contentious in Brazil for decades, would flood 500 square miles of rainforest, lead to the removal of at least 12,000 people in the region, and upturn the lives of 45,000 indigenous people who depend on the Xingu River for survival.
Amazon biodiversity older than believed
(11/11/2010) A new study in Science has found that the incredible biodiversity of the Amazon rainforest goes back much further than expected, perhaps upending old ideas about how the Amazon basin became arguably the world's most biodiverse ecosystem. According to the study, the origin of rich biodiversity in the Amazon likely goes back more than 20 million years when the Andean mountains were rising.
Rainforests thrived in warmer conditions in the past, yet study requires "caution"
(11/11/2010) A new study in Science is likely to reopen the contentious debate about the impact of climate change on tropical rainforests. Scientific modeling of future climate conditions in tropical rainforests, such as the Amazon, has shown that climate change—combined with deforestation and fire—could create a tipping point whereby a significant portion of the Amazon could turnover to savannah, pushing untold species to extinction and undercutting the many ecosystem services provided by tropical rainforests. Yet, a new study headed by Carlos Jaramillo, staff scientist at the Smithsonian Tropical Research Institute (STRI), has found a tropical forest ecosystem thriving in much warmer conditions than today.
