(04/12/2011) The destruction of 3,600 hectares (8,900 acres) of the Gran Chaco forest in Paraguay by large Brazilian cattle ranching companies has led to a legal complaint filed by a local indigenous-rights organization, since the land in question was one of the last refuges of a group of uncontacted indigenous people in the Ayoreo-Totobiegosode tribe. The loss of the forest was revealed in part by satellite images of the remote area.
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.
Conversion of Brazil's cerrado slows
(04/08/2011) Destruction of Brazil's cerrado, a woody savanna that covers 20 percent of the country, slowed during the 2008-2009, reports Brazil's Ministry of Environment.
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.
Major Brazilian banks sued for loans linked to deforestation
(04/03/2011) Brazilian prosecutors have filed suit against the state-run Banco do Brasil and Banco da Amazonia for providing loans to companies that illegally cleared Amazon rainforest and used slave-like labor, reports Reuters.
'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.
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.
How to save the Pantanal and increase profits for the cattle industry
(03/28/2011) The Pantanal spanning Brazil, Bolivia, and Paraguay is the world's largest wetland—the size of Florida—and home to a wide-variety of charismatic species, such as jaguars, capybaras, and giant anteaters. However, the great wetland is threatened by expansion in big agriculture and an increasingly intensive cattle industry. Yet there is hope: a new study by Wildlife Conservation Society of Brazil (WCS-Brazil) researchers has found that cattle and the ecosystem can exist harmoniously. By replacing current practices with rotational grazing, cattle ranchers gain a healthier herd and more profits while safeguarding the ecological integrity and wildlife of the world's largest wetland system. The study published in mongabay.com's open access journal Tropical Conservation Science is a rare instance of a win-win situation.
New seabird discovered, first in 55 years
(03/23/2011) Stephen Maturin, if he were not fictional, would be delighted. A new seabird has been discovered by an international expedition headed by one of the world's top seabird-experts, Peter Harrison, after he received photos from vacationing birders of an unusual looking storm petrel off the coast of Chile.
Climate change caused by deforestation triggers species migration
(03/23/2011) Local climate shifts caused by deforestation and land cover change are causing insects to migrate to higher — and cooler — habitats, reports a new study published in the journal Biotropica. The research has implications for predicting how species will respond to climate change.
New population discovered of the America's mini snow leopard: the Andean cat
(03/16/2011) The elusive Andean cat (Leopardus jacobita), which until the late 1990s was only known to scientists by a couple photographs, has been discovered beyond the Andes mountain range for which it is named. According to researchers, the wild Andean cat resembles Asia's snow leopard, both in appearance and its habitat above altitudes of 3,000 meters (9,800 feet), only in this case the wild cat is about the size of a domesticated feline. But, scientists have now discovered that the cat, which is listed as Endangered by the IUCN Red List, also inhabits the Patagonian steppe at elevations as low as 650 meters (2,100 feet).
Into Colombia's Sierra Nevada
(03/11/2011) The highest coastal mountain on the planet rises 18,942 feet (5,775-meters) above the Caribbean Sea; it’s snow-capped peaks piercing through the clouds some 24 miles from an idyllic tropical beach. But to the casual visitor, the Sierra Nevada of Santa Marta in Colombia does not seem so grandiose. It slopes up and down until it disappears into the clouds, jealously concealing its tropical glacier. Somewhere up there, shrouded in mystery, like an ancient treasure, hides the most impressive summit in the Caribbean. People living along this part of the coastline say the snows of the Sierra are visible from some beaches, but to me they remain elusive even after many trips to the region. To catch a glimpse of the snows from the Caribbean would be a welcoming gift, but I have really come here to experience the Sierra, whatever it would reveal.
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.
New species of zombie-creating fungi discovered
(03/02/2011) As everyone knows, human zombies are created when an uninfected human is bitten by a member of the brain-craving undead. But what about ant zombies? Yes, that's right: ant zombies.
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.
Treasure chest of wildlife camera trap photos made public
(02/27/2011) Photos taken by camera traps have not only allowed scientists to study little-seen, sometimes gravely endangered, species, they are also strangely mesmerizing, providing a momentary window—a snapshot in time—into the private lives of animals. These are candid shots of the wild with no human in sight. While many of the photos come back hazy or poor, some are truly beautiful: competing with the best of the world's wildlife photographers. Now the Smithsonian is releasing 202,000 camera trap photos to the public, covering seven projects in four continents. Taken in some of the world's most remote and untouched regions the automated cameras have captured such favorites as jaguars, pandas, and snow leopards, while also documenting little-known and rare species like South America's short-eared dog, China's golden snub-nosed monkey, and Southeast Asia's marbled cat.
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.
Researchers rediscover one of the world's most sought-after lost frogs
(02/17/2011) The Search for Lost Frogs, a global expedition to uncover amphibian species not seen for decades, has uncovered one of the expedition's most sought-after species: the Pescado stubfoot toad (Atelopus balios). The discovery in Ecuador was one bright spot in a search that revealed more about the crisis and extinctions of frogs than it did about the hopefulness of finding cryptic communities. In total the expedition rediscovered 4 of its 100 targeted species.
Worldwide search for 'lost frogs' ends with 4% success, but some surprises
(02/16/2011) Last August, a group of conservation agencies launched the Search for Lost Frogs, which employed 126 researchers to scour 21 countries for 100 amphibian species, some of which have not been seen for decades. After five months, expeditions found 4 amphibians out of the 100 targets, highlighting the likelihood that most of the remaining species are in fact extinct; however the global expedition also uncovered some happy surprises. Amphibians have been devastated over the last few decades; highly sensitive to environmental impacts, species have been hard hit by deforestation, habitat loss, pollution, agricultural chemicals, overexploitation for food, climate change, and a devastating fungal disease, chytridiomycosis. Researchers say that in the past 30 years, its likely 120 amphibians have been lost forever.
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.
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.
Monitoring deforestation: an interview with Gilberto Camara, head of Brazil's space agency INPE
(02/08/2011) Perhaps unsurprisingly, the world's best deforestation tracking system is found in the country with the most rainforest: Brazil. Following international outcry over immense forest loss in the 1980s, Brazil in the 1990s set in motion a plan to develop a satellite-based system for tracking changes in forest cover. In 2003 Brazil made the system available to the world via its web site, providing transparency on an issue that was until then seen as a badge of shame by some. Since then Brazil has become recognized as the standard-bearer for deforestation tracking and reporting—no other country offers the kind of data Brazil provides. Space engineer Gilberto Camara has overseen much of INPE's earth sensing work and during his watch, INPE has released several new exciting capabilities.
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.
Brazilian mining giant buys Amazon palm oil company
(02/03/2011) Vale, a Brazilian mining giant, will buy palm oil producer Biopalma da Amazonia SA Reflorestamento Industria & Comercio, reports Bloomberg.
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.
Incredible new photos of uncontacted tribe in the Amazon
(01/31/2011) Taken by Brazil's Indian Affairs Department and released by indigenous-rights group, Survival International, new aerial photos show an uncontacted tribe on the border of Brazil and Peru in detail. According to a press release by Survival International, the photos "reveal a thriving, healthy community with baskets full of manioc and papaya fresh from their gardens", but a community that is also threatened by illegal loggers from Peru.
Despite fierce opposition, work begins on Belo Monte dam
(01/27/2011) Arguably the most opposed dam project in the world received the go-ahead this week, reports the BBC. Brazil's environmental agency, IBAMA, has approved the first step of the massive hydroelectric project: clearing 588 acres of rainforest in the Amazon, although the dam would flood nearly 200 square miles (500 square kilometers) of forest.
Cocaine production killing Colombia's rainforests
(01/24/2011) Researchers have found that coca cultivation is associated with high rates of forest loss, at least in the southern forests of Colombia. According to a new paper just published in Environmental Science and Technology, areas near new coca plots are significantly more likely to suffer from forest loss. Politicians, environmental groups, and others have long attributed deforestation to coca production. But these researchers are the first to quantity the effect of coca cultivation while controlling for other factors.
American cougars on the decline: 'We’re running against the clock,' says big cat expert
(01/17/2011) It holds the Guinness World Record for having the most names of any animal on the planet, with 40 in English alone. It's also the widest-ranging native land animal in the Americas, yet is declining throughout much of its range. Mongabay talks with big cat expert Dr. Howard Quigley about the status and research implications of the elusive, enigmatic, and unique cougar.
Brazil's environment chief resigns over controversial Amazon dam
(01/14/2011) The president of Brazil's environmental agency IBAMA has resigned over pressure to grant a license for the Belo Monte dam, a hydroelectric project on the Xingu River that faces strong opposition from environmental groups and indigenous tribes, reports O Globo.
Renewed conflict between tribes and oil companies looms in Peru
(01/06/2011) Indigenous peoples and their allies have intensified their fight against two oil companies over contamination in the Peruvian Amazon. Last week, a group of indigenous protesters blockaded portions of the Marañon and Corrientes Rivers in the province of Loreto in northeastern Peru. The protesters were demanding that Pluspetrol, an Argentinean oil company, compensate them for a recent oil spill. As of December 28th, after eight days, the blockade remained unbroken.
Climate change could cut premontane forests of Argentina and Bolivia in half
(12/19/2010) A new study in mongabay.com's open access journal Tropical Conservation Science finds that the premontane forests of Argentina and Bolivia are susceptible to large-scale shifts due to climate change, losing over half of the ecosystem to warmer temperatures. Apart of the Yungas tropical forests, premontane forests are the lowest in the Andes, covering hills and flatland; these forests harbor significant biodiversity, yet many of those species may become threatened as the world warms.
Prominent indigenous leader gets death threats in Guyana
(12/17/2010) Environmental groups have written to Guyana president Bharrat Jagdeo over recent threats against Tony James, the President of the Amerindian Peoples Association in Guyana.
Lack of schools, trade drive exodus from remote parts of the Amazon
(12/17/2010) Lack of school access and higher costs of trade are driving an exodus from remote areas in the Amazon, a new study published in Population & Environment reveals. The research sheds light on to why people are leaving remote forest areas. It follows an earlier publication indicating that migration away from remote rural areas may have repercussions on deforestation.
Guyana: where's the money pledged for saving rainforests?
(12/09/2010) Funds ostensibly set aside to reward tropical countries for protecting their rainforests are being held up, threatening to exhaust the political capital needed to advance the proposed reducing emissions from deforestation and degradation (REDD) mechanism before it even gets off the ground, warned the president of Guyana during a lively panel organized by Avoided Deforestation Partners on the sidelines of UN climate talks in Cancun, Mexico.
Amazon tribe establishes first indigenous forest carbon fund
(12/04/2010) A half-century ago, Brazil's Suruí people knew little of the world beyond their cluster of villages – and nothing of the European settlers who dominated their continent. By 2006, that world beyond had engulfed them – a fact their young chief, Almir Narayamoga Suruí, saw all too clearly the first time he logged onto Google Earth.
2,700 sq km of Brazil's most endangered rainforest destroyed in 8 years
(12/03/2010) 270,000 hectares of the Mata Atlântica, Brazil's most threatened ecosystem, was cleared between 2002 and 2008, reports a new assessment by the Brazilian Institute of Environment and Natural Resources (IBAMA). Less than 8 percent of the Atlantic forest—famed for its biodiversity—remains.
Brazil's largest national bank signs zero deforestation pact for Amazon soy
(12/03/2010) Banco do Brasil, Brazil's largest state-owned bank, announced it has joined a zero deforestation pact for soy grown in the Amazon. The bank will now require farmers applying for credit to certify the origin of their soybeans.
'Environmental and social aggression': oil exploration threatens award-winning marine protected area
(12/01/2010) The Seaflower Marine Protected Area (MPA), which recently won top honors at the Convention on Biological Diversity (CBD) in Japan, is now under threat by planned oil exploration in the region, according to the Providence Foundation which is devoted to protecting the area. Proposed blocs for exploration by the Colombian government lie in the North Cays adjacent to the park, and perhaps even inside MPA boundaries. Spreading over 65,000 square kilometers (6.5 million hectares), Seaflower MPA lies within the Colombian Caribbean department known as the Archipelago of San Andres, Old Providence and Santa Catalina. This richly diverse Archipelago is home to a known 57 coral species, over 400 fish, and some 150 birds, as well as the ethnic and cultural minority: the Raizal people. The prospect of massive infrastructure or, even worse, oil spills in the area could devastate the park and locals' livelihoods.
Brazil's Amazon deforestation rate falls to lowest on record
(12/01/2010) Deforestation in the Brazilian Amazon fell to the lowest rate on record, putting Brazil well on track to meet its targets for reducing rainforest destruction. Analysis of satellite imagery by Brazil’s National Institute for Space Research (INPE) shows that 6,450 square kilometers of rainforest were cleared in the Amazon in the 12 months ended July 31, 2010, a 14 percent drop from the year earlier period.
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.
Good stewards of forests at home outsource deforestation abroad
(11/24/2010) As more nations adopt better laws and policies to save and restore forests at home, they may, in fact, be outsourcing deforestation to other parts of the world, according to a new study in the Proceedings of the National Academy of Sciences (PNAS). Looking at six developing nations where forests are recovering—instead of receding—the study found only one of them did not outsource deforestation to meet local demand for wood-products and food, a process known as 'leakage'.
Record number of nations hit all time temperature highs
(11/23/2010) To date, nineteen nations have hit or matched record high temperatures this year, according to Jeff Master's Wunder Blog, making 2010 the only year to have so many national records. In contrast, no nation this year has hit a record cold temperature.
