Buffer zones key to survival of maned wolf
(09/17/2012) Known for its abnormally long lanky legs, its reddish-orange coat, and its omnivorous diet, the maned wolf (Chrysocyon brachyurus) is one of the more beautiful and bizarre predators of South America. However its stronghold, the Brazilian Cerrado, is vanishing rapidly to industrialized agriculture and urban development. Now, a new study in mongabay.com's open access journal Tropical Conservation Science reveals the key role of buffer zones and unprotected areas in keeping the maned wolf from extinction in the Cerrado savannah, where only 2 percent of the ecosystem is under protection.
Over 80 species targeted by hunters in Brazil's northeast
(09/17/2012) A new survey of hunting in Brazil's northeastern state of Paraíba, finds that hunters target, often illegally over 80 species for food, the pet trade, medicine, leather, fur, and ornaments. Over half of the species, mainly birds and mammals, are targeted for food, according to the research published in mongabay.com's open access journal Tropical Conservation Science.
Pictures: Bolivian park may have the world's highest biodiversity
(09/12/2012) With over 90 species of bat, 50 species of snake, 300 fish, 12,000 plants, and 11 percent of the world's bird species, Madidi National Park in Bolivia may be the world's most biodiverse place, according to new surveys by the the Bolivian Park Service (SERNAP) with aid from the Wildlife Conservation Society (WCS).
Amazon deforestation could trigger drop in rainfall across South America
(09/06/2012) Deforestation could cause rainfall across the Amazon rainforest to drop precipitously, warns a new study published in the journal Nature. Using a computer model that accounts for forest cover and rainfall patterns, Dominick Spracklen of the University of Leeds and colleagues estimate that large-scale deforestation in the Amazon could reduce basin-wide rainfall 12 percent during the wet season and 21 percent in the dry season by 2050. Localized swings would be greater.
Spike in glacier melt across Patagonia since 2000
(09/05/2012) The rate of glacier melt across Patagonia has accelerated since 2000, reports a new study published in the journal Geophysical Research Letters.
Forest expands 3% in Colombia during 2000s, but loss grows in llanos region
(09/04/2012) Colombia gained nearly 17,000 square kilometers of forest between 2001 and 2010 as forests recovered in mountainous regions in the Andes, reports a new study published in the journal PLoS One.
Bolivia should prioritize cattle ranching, law enforcement in deforestation fight
(09/04/2012) Bolivia should prioritize environmental law enforcement and slowing expansion of large-scale cattle ranching to reduce Amazon deforestation, argues a study published last month by researchers from Germany and the Center for International Forestry Research (CIFOR).
Survivors say gold miners in helicopter massacred village of 80 in Venezuelan Amazon
(08/30/2012) Up to 80 people have been massacred by gold miners in the remote Venezuelan Amazon, according to reports received by the indigenous-rights group, Survival International. According to Reuters, the reports have prompted the Venezuelan government to investigate the alleged murders of the Yanomami isolated community. According to three indigenous survivors, sometime in July a helicopter and what-are-believed to be illegal goldminers massacred the Yanomami community of Irotatheri.
Emissions from Amazon deforestation in Brazil fall 57% since 2004
(08/29/2012) Annual emissions from deforestation in the Brazilian Amazon fell by about 57 percent between 2004 and 2011, 20 percentage points lower than the recorded drop in deforestation, reports a new study published in the journal Global Change Biology by Brazilian scientists. Overall, Brazilian deforestation represented roughly 1.5 percent of global carbon emissions from human activities.
Unidentified poodle moth takes Internet by storm
(08/29/2012) A white moth from Venezuela that bears a striking resemblance to a poodle has become an Internet sensation, after cryptozoologist Karl Shuker posted about the bizarre-looking species on his blog. Photographed in 2009 in Venezulea's Canaima National Park in the Gran Sabana region by zoologist Arthur Anker from Kyrgyzstan, the white, cuddly-looking moth with massive black eyes has yet to be identified and could be a species still unknown to science.
Private reserve safeguards newly discovered frogs in Ecuadorian cloud forest
(08/28/2012) Although it covers only 430 hectares (1,063 acres) of the little-known Chocó forest in Ecuador, the private reserve las Gralarias in Ecuador is home to an incredible explosion of life. Long known as a birder's paradise, the Reserva las Gralarias is now making a name for itself as a hotspot for new and endangered amphibians, as well as hundreds of stunning species of butterfly and moth. This is because the reserve is set in the perfect place for evolution to run wild: cloud forest spanning vast elevational shifts. "The pacific slope cloud forests [...] are among the most endangered habitats in the world," explains Reserva las Gralarias' founder, Jane Lyons, in a recent interview with mongabay.com.
Dry forests disappearing faster than rainforests in Latin America
(08/21/2012) Countries across Latin America lost 78,000 square kilometers of subtropical and tropical dry broadleaf forests between 2001 and 2010, according to a new satellite-based assessment published in the journal Biotropica.
Chart: Forest loss in Latin America
(08/20/2012) Latin America lost nearly 260,000 square kilometers (100,000 square miles) of forest — an area larger than the state of Oregon — between 2001 and 2010, finds a new study that is the first to assess both net forest loss and regrowth across the Caribbean, Central and South America. The study, published in the journal Biotropica by researchers from the University of Puerto Rico and other institutions, analyzes change in vegetation cover across several biomes, including forests, grasslands, and wetlands. It finds that the bulk of vegetation change occurred in forest areas, mostly tropical rainforests and lesser-known dry forests. The largest gains in biome area occurred in desert vegetation and shrublands.
New bird discovered in Colombia imperiled by hydroelectric project
(08/19/2012) In a little-known dry forest in Colombia, scientists have discovered a new species of bird: the Antioquia wren (Thryophilus sernai). First seen in 2010, scientists photographed the new wren and recorded its vocalizations, from which they determined that the wren was brand new to science, according to a new paper in Auk.
Move to regularize mining in Colombia spurs concerns
(08/17/2012) Colombia's move last week to begin granting new mining concessions across 17.6 million hectares has raised concerns about the potential environmental impacts of a new mining boom across the country.
Key mammals dying off in rainforest fragments
(08/15/2012) When the Portuguese first arrived on the shores of what is now Brazil, a massive forest waited for them. Not the Amazon, but the Atlantic Forest, stretching for over 1.2 million kilometers. Here jaguars, the continent's apex predator, stalked peccaries, while tapirs waded in rivers and giant anteaters unearthed termites mounds. Here, also, the Tupi people numbered around a million people. Now, almost all of this gone: 93 percent of the Atlantic Forest has been converted to agriculture, pasture, and cities, the bulk of it lost since the 1940s. The Tupi people are largely vanished due to slavery and disease, and, according to a new study in the open access journal PLoS ONE, so are many of the forest's megafauna, from jaguars to giant anteaters.
Belo Monte mega-dam halted again by high Brazilian court, appeal likely but difficult
(08/15/2012) A high federal court in Brazil has ruled that work on the Belo Monte dam in the Brazilian Amazon be immediately suspended. Finding that the government failed to properly consult indigenous people on the dam, the ruling is the latest in innumerable twists and turns regarding the massive dam, which was first conceived in the 1970s, and has been widely criticized for its impact on tribal groups in the region and the Amazon environment. In addition the Regional Federal Tribunal (TRF1) found that Brazil's Environmental Impact Assessment was flawed since it was conducted after work on the dam had already begun.
Evidence of 'isolated' indigenous people found in Peru where priest is pushing highway
(08/14/2012) Evidence of indigenous people living in "voluntary isolation" in a remote part of the Amazon has been found where an Italian Catholic priest is campaigning for Peru’s government to build a highway. The discovery is controversial because the priest has questioned the existence of the isolated people, sometimes referred to as uncontacted, who live without regular contact with anyone else.
Rodent robbers fill role of mega mammals, help spread tropical trees
(08/07/2012) In order to disperse their seeds, large-fruited tropical trees probably relied on massive mammals that roamed the earth over 10,000 years ago. But with giants such as the mastodon now extinct, thieving rodents—who continually excavate and rebury others' seeds—may be filling their role, according to a new study in the Proceedings of the National Academy of Sciences (PNAS).
Beautiful new bird discovered in Peruvian cloud forest
(08/07/2012) Four years ago in a remote cloud forest in Peru's Cerros del Sira mountain range, three recently graduated students from Cornell University discovered a never-before-recorded species of black, white, and scarlet bird. Now described in the scientific journal, The Auk, the bird has been dubbed the Sira barbet (Capito fitzpatricki).
'The lion of the cave:' new predatory, swimming cricket discovered in Venezuela
(08/06/2012) Scientists have discovered what is likely a new species of cricket that is the top predator of its lightless world: a cave in a Venezuelan tepui. The fauna of cave was documented by BBC filmmakers as researchers uncovered not only a large, flesh-eating cricket but a new species of catfish.
Pig iron producers sign zero deforestation pledge after Greenpeace campaign
(08/02/2012) Pig iron producers in the Brazilian state of Maranhão today pledged to stop using charcoal produced from Amazon rainforest logging, reports Greenpeace, which had waged a zero deforestation campaign targeting foreign automakers that buy steel from the industry.
Peru considers big changes to its environmental reviews
(08/01/2012) The Peruvian government is looking into making large-scale changes to its Environment Impact Assessments (EIA) after a review found significant problems with the vast majority of past reviews, reports the Inter Press Service. The news comes a few weeks after protests over a proposed gold and copper mine in the Andes left five people dead, including a 17-year-old boy.
Human rights court favors indigenous tribe over Ecuadorian government in oil battle
(07/31/2012) The Inter-American Court of Human Rights has found in favor of a Kichwa community's right to consultation prior to industrial projects on their land in a ruling that could have implications for many indigenous peoples across the Americas. The court found that the government of Ecuador violated the indigenous people's rights by allowing the Argentine oil company, Compania General de Combustibles (CGC), on their land without proper consultation.
Guyana rainforests secure trust fund
(07/30/2012) The nation of Guyana sports some of South America's most intact and least-imperiled rainforests, and a new $8.5 million trust fund hopes to keep it that way. The Guyanese government has teamed up with Germany and Conservation International (CI) to create a long-term trust fund to manage the country's protected areas system (PAS).
Brazil decree opens tribal lands to mining, dams in 'national interest'
(07/26/2012) A directive signed Monday by Brazil’s Solicitor-General could hamper the efforts of indigenous tribes to win government recognition of their traditional lands, reports Survival International, a human rights group focused on native peoples. The directive 'opens up all indigenous areas to mineral, dams, roads, military bases and other developments of 'national interest' without the need to consult with or address concerns of indigenous peoples', according to an expert familiar with the directive.
Indigenous tribes hold 3 engineers hostage over Belo Monte dam
(07/26/2012) Three engineers are being held hostage by the Juruna and Arara indigenous tribes as tensions rise over the on-going construction of the Belo Monte dam in Brazil, reports the Indigenous rights NGO Amazon Watch. The company building the dam, Norte Energia, has confirmed that three of its employees were being held against their will. Tribal groups in the region say the massive dam will upend their way of life, and that construction is already making travel along the Xingu river difficult.
Camera traps discover new populations of nearly extinct chinchillas
(07/25/2012) The short-tailed chinchilla (Chinchilla chinchilla) once inhabited a range including the mountainous regions of Argentina, Bolivia, Chile and Peru, but today the species survives in only a handful of areas in northern Chile and Argentina. Worse still, evidence of the Argentinean populations are restricted to remains discovered in the droppings of their natural predators. But, since 2011, Pablo Valladares from the University of Tarapaca in conjunction with the National Forestry Corporation of Chile (CONAF) has been searching Tres Cruces National Park for previously undocumented populations, and it has finally paid off: Valladares and colleagues discovered two new colonies with remote camera traps.
Brazil cripples illegal gold mining operations in indigenous territory
(07/18/2012) Brazilian police have arrested 26 people and confiscated gold and aircraft in a coordinated effort to tackle illegal gold-mining in the Yanomami Indigenous Reserve, reports the BBC. Along with illegal miners the year-long investigation also arrested complicit airplane pilots, engineers, and business people in a bid to undercut the trade's funders and infrastructure.
Over 500 dead penguins wash up in Brazil, cause under investigation
(07/17/2012) In recent weeks, 512 Magellanic penguins (Spheniscus magellanicus) have washed up dead in Brazilian state of Rio Grande do Sul. Although badly composed, researchers do not see any obvious signs why the penguins died, especially in such numbers. Marine biologists are currently performing autopsies on carcasses and hope to determine cause of death within a few weeks.
Still time to save most species in the Brazilian Amazon
(07/12/2012) Once habitat is lost or degraded, a species doesn't just wink out of existence: it takes time, often several generations, before a species vanishes for good. A new study in Science investigates this process, called "extinction debt", in the Brazilian Amazon and finds that 80-90 percent of the predicted extinctions of birds, amphibians, and mammals have not yet occurred. But, unless urgent action is taken, the debt will be collected, and these species will vanish for good in the next few decades.
Indigenous tribes end occupation of Belo Monte
(07/12/2012) After occupying the construction site of the massive Belo Monte dam for 21 days, some 300 indigenous people have left and gone home. The representatives from nine Amazonian tribes abandoned their occupation after two days of meeting with the dam's builder, the Norte Energia consortium.
Vietnam buys stakes in controversial oil blocks threatening Peru's most vulnerable indigenous people
(07/11/2012) Vietnam's state oil and gas company, PetroVietnam Exploration and Production (PVEP), has announced its intention to acquire a major stake in controversial oil operations in the remote Peruvian Amazon. This area, known as Lot 67, is one of the most biodiverse in the world and home to indigenous people living without regular contact with outsiders, sometimes dubbed 'isolated' or 'uncontacted', who could be decimated by contact with oil company workers because they are highly vulnerable to disease.
Predicting the distribution of tropical dung beetles
(07/09/2012) Although they live in almost every ecosystem in the world—from your backyard to the Antarctic—scientists know very little about many insect species, including many individual species' distribution. A new study in mongabay.com's open-access journal Tropical Conservation Science attempts to predict the range of 53 dung beetle species in the genus Eurysternus, all of which are found in the American tropics. Dung beetles are hugely important to their environments, since they efficiently devour and recycle waste.
Indigenous tribes occupy Belo Monte dam for over 10 days
(07/03/2012) As of Tuesday, the occupation of Belo Monte dam by indigenous tribes entered its 13th day. Indigenous people, who have fought the planned Brazilian dam for decades, argue that the massive hydroelectric project on the Xingu River will devastate their way of life. According to a statement from the tribes, 17 indigenous villages from 13 ethnic groups are now represented at the occupation, which has successfully scuttled some work on the dam.
96 percent of the world's species remain unevaluated by the Red List
(06/28/2012) Nearly 250 species have been added to the threatened categories—i.e. Vulnerable, Endangered, and Critically Endangered—in this year's update of the International Union for Conservation of Nature's (IUCN) Red List. The 247 additions—including sixty bird species—pushes the number of threatened species globally perilously close to 20,000. However to date the Red List has only assessed 4 percent of the world's known species; for the other 96 percent, scientists simply don't know how they are faring.
Agricultural area larger than Texas has been 'land-grabbed'
(06/26/2012) Compiling over 1,000 foreign land deals from 2000-2010, a new report finds that 702,000 square kilometers (271,043 square miles) of agricultural land worldwide has been sold-off to foreign governments or international corporations, an area larger than Texas. The report by the Worldwatch Institute finds that such land deals, often referred to as "land grabbing," have declined since a peak in 2009, but still remain high.
Lonesome George passes, taking unique subspecies with him
(06/25/2012) Lonesome George, the sole surviving member of the Pinta Island tortoise (Chelonoidis nigra abingdoni), was found dead on Sunday by staff at the Galapagos National Park. With George's passing, the Pinta Island tortoise subspecies officially falls into extinction. First found in 1972, Lonesome George became famous for representing the last of his kind. He was believed to be around 100—middle-aged for a Galapagos tortoise which can live to 200 years old. Staff plan to do an autopsy to determine the cause of death.
Small farmers cause substantial damage in the Amazon rainforest
(06/25/2012) Small farmers are less likely than large landowners to maintain required forest cover on their property in the Brazilian Amazon, worsening the environmental impact of their operations, reported a researcher presenting at the annual meeting of the Association for Tropical Biology and Conservation (ATBC) in Bonito, Brazil.
Frog secretion illicitly used to help racehorses run faster
(06/21/2012) A compound found in the secretions of a South American frog is being used to boost the performance of racehorses, reports The New York Times.
Fire risk to increase in the Amazon rainforest
(06/20/2012) The risk of fire could increase across large parts of the Amazon rainforest due to increasing incident of drought, expansion of road networks, and rural outmigration, said a scientist speaking at the annual meeting of the Association for Tropical Biology and Conservation (ATBC) in Bonito, Brazil.
Cowards at Rio?: organizations decry 'pathetic' agreement
(06/20/2012) As world leaders head to Rio de Janeiro for the UN Summit on Sustainable Development, environmental and poverty groups are denouncing the last-minute text agreed on by dignitaries as "pathetic," (Greenpeace), a "damp squib" (Friends of the Earth), "a dead end" (Oxfam), and, if nothing changes, "a colossal waste of time" (WWF). "We were promised the 'future we want' but are now being presented with a 'common vision' of a polluter’s charter that will cook the planet, empty the oceans and wreck the rain forests,“ the head of Greenpeace, Kumi Naidoo, said. "This is not a foundation on which to grow economies or pull people out of poverty, it’s the last will and testament of a destructive twentieth century development model."
Protecting jaguars a good business decision for ranchers
(06/20/2012) Live jaguars are worth considerably more for ecotourism than they livestock they kill, according to a study presented at the annual meeting of the Association for Tropical Biology and Conservation in Bonito, Brazil.
Photo: Human canvas on Rio beach protests Brazil's dam-building spree in the Amazon
(06/20/2012) Nearly 1500 people formed a human banner on a beach in Rio de Janeiro today to protest plans to build dozens of dams in the Amazon basin, reports Amazon Watch, an NGO campaigning against Brazil's controversial Belo Monte dam.
Over 700 people killed defending forest and land rights in past ten years
(06/19/2012) On May 24th, 2011, forest activist José Cláudio Ribeiro da Silva and his wife, Maria do Espírito Santo da Silva, were gunned down in an ambush in the Brazilian state of Pará. A longtime activist, José Cláudio Ribeiro da Silva had made a name for himself for openly criticizing illegal logging in the state which is rife with deforestation. The killers even cut off the ears of the da Silvas, a common practice of assassins in Brazil to prove to their employers that they had committed the deed. Less than a year before he was murdered, da Silva warned in a TEDx Talk, "I could get a bullet in my head at any moment...because I denounce the loggers and charcoal producers."
WWF: biggest villain at Rio+20 is Canada
(06/18/2012) Having sent a delegation to the United Nation's Rio+20 Summit on Sustainable Development, the World Wide Fund for Nature (WWF), the world's biggest conservation group, has recently declared their Heroes and Villains of Rio+20—so far. The NGO has strong words for the negotiating position of the U.S. and the major oil exporting countries (OPEC), but saves its harshest criticisms for Canada.
Experts: ignoring climate change at Rio+20 makes other goals "meaningless"
(06/18/2012) The Climate Change Task Force (CCTF)—made up of 30 climate scientists, other experts and world leaders—warned today that sidelining climate change at the Rio+20 Summit on Sustainable Development threatened progress on the conference's other goals, which includes combating poverty and building economies that value nature. "I am very concerned and worried because the draft final document of the Rio+20 conference does not give proper attention to climate change," says former Russian President Mikhail Gorbachev in a press statement.
World failing to meet promises on the oceans
(06/14/2012) Despite a slew of past pledges and agreements, the world's governments have made little to no progress on improving management and conservation in the oceans, according to a new paper in Science. The paper is released just as the world leaders are descending on Rio de Janeiro for Rio+20, or the UN Summit on Sustainable Development, where one of the most watched issues is expected to be ocean policy, in part because the summit is expected to make little headway on other global environmental issues such as climate change and deforestation. But the new Science paper warns that past pledges on marine conservation have moved too slowly or stagnated entirely.
Featured video: the Rio speech heard round the world
(06/14/2012) As world leaders, officials, NGOs, businesses, and experts gather in Rio de Janeiro for the UN Summit on Sustainable Development, or more well known as Rio+20, it might be useful to look at the landmark Rio Earth Summit in 1992, which helped propel environmental concerns around the world. The most noteworthy speech during that meeting was made by a twelve year old Canadian girl, Severn Suzuki.
Animal picture of the day: the beautiful black-necked swan (and babies)
(06/12/2012) The black-necked swan (Cygnus melancoryphus) is South America's largest waterfowl, but the smallest of the world's swans. When newborn, babies, who are called cygnets, often ride on their parents back for safety.
