(12/18/2014) A study by researchers in Brazil published this week has found that deforestation in the Southern Amazon may impair significantly the structure and function of rivers, and make them less able to support life.
Plant wars: some tree species compete better against grasses for reforestation
(12/18/2014) What happens to degraded pastureland once the cows are kicked out? After years of letting the area rest, does it eventually become what it once was? Not likely. When disruptions such as invasive species and human interference are introduced to an area, ecological succession doesn’t occur the way it should naturally.
Scientists reintroduce agoutis in rainforest in city of 12 million
(12/17/2014) When one thinks of Rio de Janeiro, one usually doesn't think: rainforest. However, in the heart of the city sits a massive rainforest sprung over long-gone sugar and coffee plantations. The forest—protected today as the Tijuca National Park—is home to hundreds of threatened species, but no agoutis, a common ground mammal in Latin America.
An app to save 400 million animals
(12/11/2014) Brazilian biologist Alex Bager has been leading a crusade to raise awareness of a major but neglected threat to biodiversity in his country. Every year over 475 million animals die in Brazil as victims of roadkill, according to an estimate by Centro Brasileiro de Ecologia de Estradas, an initiative funded and coordinated by Bager. This means 15 animals are run down every second on Brazilian roads and highways.
False victories for sustainability – Amazonian Hydropower
(12/09/2014) Dams are hugely controversial, especially in the Amazon Rainforest. Their proponents, flashing green credentials, have dammed the tributaries of the Amazon for decades. However, there is a rising backlash against the huge economical, environmental, and sociological costs dams bring. A paper led by Dr. James Randall Kahn from Washington and Lee University is the latest in this volley.
New endangered bird species discovered in Brazil
(12/04/2014) The Bahian mouse-colored tapaculo (Scytalopus gonzagai) has only just been discovered by scientists in the heavily logged Atlantic Forest of southeast Brazil -- and it’s already believed to be endangered.
Threatened indigenous forests store more than half the Amazon's carbon
(12/02/2014) A new study released today finds the total carbon load locked up in parts of the Amazon rainforest held by indigenous groups to be much higher than previously estimated – an amount that, if released, would be capable of destabilizing the earth’s atmosphere. But because of flimsy land rights, these areas stand at risk of deforestation.
Amazon deforestation in Brazil drops 18% in 2013/2014
(11/26/2014) Figures published Wednesday by Brazil's National Space Research Institute (INPE) show that 4,848 square kilometers (1,871 square miles) of forest — an area about the size of the state of Rhode Island or the country of Brunei — were cleared between August 2013 and July 2014.
Rising deforestation, fossil fuels use drive Brazil's emissions 8% higher
(11/24/2014) Brazil's carbon emissions jumped 7.8 percent in 2013 due to rising deforestation and fossil fuels use, according to data released by Observatório do Clima (Climate Observatory), an alliance of mostly Brazilian non-profits.
Brazilian government silent as deforestation rises in the Amazon
(11/17/2014) Deforestation in the Brazilian Amazon continues to outpace last year's rate by a significant margin, reveals data released today by Imazon, a Brazilian non-profit. Imazon's analysis of satellite data shows that for the 3-month period ended October 31, 2014, deforestation is running 226 percent of last year's rate. Forest degradation, which often precedes outright clearing, is pacing 691 percent ahead of last year.
Greenpeace investigation prompts Belgian authorities to seize timber shipment
(11/16/2014) Authorities in Belgium seized two containers of Brazilian timber in Antwerp following a demonstration by Greenpeace, which alleged that the Ipe timber had been cut illegally and therefore violated the EU's trade laws.
New tapir? Scientists dispute biological discovery of the century
(11/13/2014) Nearly a year ago, scientists announced an incredible discovery: a new tapir species from the western Amazon in Brazil and Colombia. The announcement was remarkable for a number of reasons: this was the biggest new land mammal discovered in more than 20 years and was only the fifth tapir known to the world. But within months other researchers expressed doubt over the veracity of the new species.
New laws may turn Brazil's forests into mines
(11/07/2014) With the world’s largest system of protected areas and a 70 percent drop in the deforestation rate of the Amazon over the past decade, Brazil has made huge strides in safeguarding what’s left of its wilderness. However, this progress now hangs in the balance, with new laws threatening to turn many of the country’s protected areas into mines and dams.
Brazilian tribes demarcate territory in bid to block dams
(11/06/2014) Indigenous communities in Brazil have taken the unusual step of demarcating their own land — without the approval of the Brazilian government — in a bid to block two dams they say threaten their territory and traditional livelihoods, report International Rivers and Amazon Watch, advocacy groups that are fighting the projects. Last week the Munduruku people annexed the 178,000-hectare Sawré Muybu territory after authorities failed to recognize their claims.
Reducing tax evasion could help save the Amazon
(11/04/2014) Taxing underutilized land in the Amazon could conserve forests, boost productivity, and alleviate poverty, argues study.
Facing severe drought, 'war effort' needed to save the Amazon, says scientist
(11/03/2014) Severe droughts in southern Brazil may be linked to deforestation and degradation of Earth's largest rainforest, argues a new report published by a Brazilian scientist. Reviewing data from roughly 200 studies, Antonio Donato Nobre of Brazil's National Institute for Space Research (INPE) warns that reducing deforestation will not be enough to restore the ecological function of the Amazon rainforest, which acts as a giant water pump that delivers precipitation across much of South America.
De-protection of Protected Areas ramps up in Brazil, 'compromises the capacity' of ecosystems
(10/31/2014) Brazil has reserved about 17.6 percent of its land (1.5 million square kilometers) to receive protection from unauthorized exploitation of resources. However, despite significant expansions in protected areas since the mid-2000s, the formation of Protected Areas has stagnated in the country since 2009, and many have had their protections completely revoked.
Beef, palm oil, soy, and wood products from 8 countries responsible for 1/3 of forest destruction
(10/23/2014) Four commodities produced in just eight countries are responsible for a third of the world's forest loss, according to a new report. Those familiar with the long-standing effort to stop deforestation won't be surprised by the commodities named: beef, palm oil, soy, and wood products (including timber and paper). Nor will they be very surprised by most of the countries: Brazil, Indonesia, and Malaysia.
Brazil declares new protected area larger than Delaware
(10/23/2014) Earlier this week, the Brazilian government announced the declaration of a new federal reserve deep in the Amazon rainforest. The protections conferred by the move will illegalize deforestation, reduce carbon emissions, and help safeguard the future of the area’s renowned wildlife.
Gold mining expanding rapidly along Guiana Shield, threatening forests, water, wildlife
(10/22/2014) Gold mining is on the rise in the Guiana Shield, a geographic region of South America that holds one of the world’s largest undisturbed tract of rainforest. A new mapping technology using a radar and optical imaging combination has detected a significant increase in mining since 2000, threatening the region's forests and water quality.
Daring activists use high-tech to track illegal logging trucks in the Brazilian Amazon
(10/15/2014) Every night empty trucks disappear into the Brazilian Amazon, they return laden with timber. This timber —illegally cut —makes its way to a sawmills that sell it abroad using fraudulent paperwork to export the ill-gotten gains as legit. These findings are the result of a daring and dangerous investigation by Greenpeace-Brazil.
As Amazon deforestation falls, small farmers play bigger role in forest clearing
(10/14/2014) Smallholder properties account for a rising proportion of overall deforestation in Brazilian Amazon, suggesting that Brazil’s progress in cutting forest loss through stricter law enforcement may be nearing the limits of its effectiveness, finds a new study published in the Proceedings of the National Academy of Sciences.
Forest fragmentation's carbon bomb: 736 million tonnes C02 annually
(10/09/2014) Scientists have long known that forest fragments are not the same ecologically as intact forest landscapes. When forests are slashed into fragments, winds dry out the edges leading to dying trees and rising temperatures. Biodiversity often drops, while local extinctions rise and big animals vanish. Now, a new study finds another worrisome impact of forest fragmentation: carbon emissions.
Brazil unlikely to sustain gains in reducing deforestation without new incentives for ranchers, says study
(10/09/2014) Cattle ranchers that drive the vast majority of forest clearing in the Brazilian Amazon are unlikely to be held at bay indefinitely unless they are afforded new incentives for keeping trees standing, argues new analysis published by an economic research group. The findings suggest that Brazil's recent progress in reducing deforestation — annual forest loss in the region has dropped by roughly 80 percent since 2004 — could easily be reversed.
Dogs may be responsible for declining mammals in Brazil’s agroforests
(09/26/2014) With an estimated population of 700 million individuals, domestic dogs are the most abundant carnivore in the world and are present everywhere that man has settled. Domestic dogs are not usually viewed as a huge threat to wildlife and native habitats, but according to a recent study dogs fit all three categories to be considered an invasive species and may be decimating mammals in agroforests in Brazil.
Drivers in Brazil will intentionally run-down small animals, but only if it is safe
(09/24/2014) Although not always very wide, roads can be huge barriers to wildlife. Not only do roads break up habitats, making animal movement more difficult, but they also allow people into long-inaccessible natural areas. A new study in mongabay.com’s open-access journal Tropical Conservation Science looks at how drivers on Brazil’s MG-010 road act when faced with small animals, such as snakes, on the path.
Brazil cancels Tapajos dam auction due to indigenous concerns
(09/19/2014) Brazilian authorities have suspended the auction of the centerpiece of the massive Tapajos hydroelectric complex, reports Agencia Brasil.
Brazil's planned Tapajós dams would increase Amazon deforestation by 1M ha
(09/14/2014) A plan to build a dozen dams in the Tapajós river basin would drive the loss of an additional 950,000 hectares of rainforest by 2032 by spurring land speculation and mass migration to the region, suggests a new study published by Imazon, a Brazilian NGO.
Brazil confirms last year's rise in Amazon deforestation
(09/12/2014) Brazil's National Space Agency INPE has officially confirmed last year's rise in Amazon deforestation.
Canada, Russia, Brazil lead world in old-growth forest loss
(09/05/2014) Every day, the world loses about 50,000 hectares of forest to agricultural clearing, road development, and other human activities, constricting true wilderness into smaller and smaller areas – along with the species that inhabit them. New analysis and maps released this week show these last vestiges are disappearing at a quick pace, with more than 104 million hectares degraded from 2000 to 2013.
Scientists uncover five new species of 'toupee' monkeys in the Amazon
(09/02/2014) While saki monkeys may be characterized by floppy mops of hair that resemble the worst of human toupees, these acrobatic, tree-dwelling primates are essential for dispersing seeds. After long being neglected by both scientists and conservationists, a massive research effort by one intrepid researcher has revealed the full-scale of saki monkey diversity, uncovering five new species.
Authorities stop 'greatest destroyers of the Brazilian Amazon rainforest'
(08/28/2014) A criminal organization involved in the illicit deforestation of large portions of Brazil's forests has been stopped, with at least six members of the organization arrested as of Aug. 28 and warrants issued for others. The gang has been accused of committing crimes worth over $220 million.
Saving the Atlantic Forest would cost less than 'Titanic'
(08/28/2014) Want to save the world's most imperiled biodiversity hotspot? You just need a down payment of $198 million. While that may sound like a lot, it's actually less than it cost to make the film, Titanic. A new study published today in Science finds that paying private landowners to protect the Atlantic Forest would cost Brazil just 6.5 percent of what it currently spends ever year on agricultural subsidies.
Invasion of the lionfish: new research finds the situation may be worse than we thought
(08/27/2014) You may have recently read the controversial story on invasive lionfish research involving Dr. Zack Jud of Florida International University and a young girl named Lauren Arrington. While the issue of attribution in scientific research is crucial to the discipline, much of the media focus so far has sidestepped the real issue: what lionfish tolerance for brackish water really means for the environment.
How do we save the world's vanishing old-growth forests?
(08/26/2014) There's nothing in the world like a primary forest, which has never been industrially logged or cleared by humans. They are often described as cathedral-like, due to pillar-like trees and carpet-like undergrowth. Yet, the world's primary forests—also known as old-growth forests—are falling every year, and policy-makers are not doing enough to stop it.
Norway puts $1.6B into rainforest conservation
(08/19/2014) Since 2008 Norway has been the single largest foreign donor to tropical forest conservation, putting more than 10 billion Norwegian Krone, or $1.6 billion, toward programs in several countries under its International Climate and Forest Initiative. But how effective have those funds been in actually protecting forests?

(07/24/2014) Deforestation is compromising forests around the world, destroying vital habitat and causing greenhouse gases emissions that are contributing to global warming. A new report released today finds a possible solution: protecting forests by empowering the local communities that live within them.
Targeted enforcement saved a Massachusetts-worth of Amazon rainforest in 3 years
(07/24/2014) Targeted law enforcement efforts via Brazil's green municipalities programs were responsible for reducing deforestation by 10,653 square kilometers — an area the size of Massachusetts — between 2009 and 2011, argues a paper published in the journal Land Use Policy.
Brazil could meet all its food demand by 2040 without cutting down another tree
(07/24/2014) Better utilization of its vast areas of pasturelands could enable Brazil to dramatically boost agricultural production without the need to clear another hectare of Amazon rainforest, cerrado, or Atlantic forest, argues a new study published in the journal Global Environmental Change.
Phone-based logging alert system eyes expanding to the Amazon
(07/23/2014) After exceeding an ambitious fundraising target to launch a near-real time forest monitoring system in the Congo Basin, a San-Francisco based start-up is now eyeing expansion in the Amazon where it hopes to help an indigenous rainforest tribe fight illegal logging.
Roads through the rainforest: an overview of South America's 'arc of deforestation'
(07/21/2014) When a new road centipedes its way across a landscape, the best of intentions may be laid with the pavement. But roads, by their very nature, are indiscriminate pathways, granting access for travel and trade along with deforestation and other forms of environmental degradation. And as the impacts of roads on forest ecosystems become clear, governments and planning agencies reach a moral crossroads.
Only 15 percent of world's biodiversity hotspots left intact
(07/14/2014) The world's 35 biodiversity hotspots—which harbor 75 percent of the planet's endangered land vertebrates—are in more trouble than expected, according to a sobering new analysis of remaining primary vegetation. In all less than 15 percent of natural intact vegetation is left in the these hotspots, which include well-known jewels such as Madagascar, the tropical Andes, and Sundaland.
Good intentions, collateral damage: forest conservation may be hurting grasslands
(07/10/2014) Trees absorb CO2 and trap carbon molecules, and countless are lost as forests are felled around the world. So why not plant as many as we can? A recent paper suggests otherwise; the planting of more trees through international reforestation schemes may actually be harming tropical grasslands, which harbor endemic species and offer unique ecosystem services.
A garden or a wilderness? One-fifth of the Amazon may have been savannah before the arrival of Europeans
(07/09/2014) The Amazon is the largest tropical forest on the planet, covering about 6.5 million square kilometers, although much has been lost in recent decades.Yet new research published in the Proceedings of the National Academy of Sciences (PNAS) finds that quite recently—just 500 years ago—a significant portion of the southern Amazon was not the tall-canopied forest it is today, but savannah.
A fine line: new program predicts when human impact becomes too much
(07/03/2014) Scientists at Stanford University recently unveiled a new modeling program that can predict the response of the environment to the land-use changes of human communities. Using their model, they found that natural resources can support humanity – up to a certain point.
A children's book inspired by murder: the 25th anniversary of 'The Great Kapok Tree'
(07/03/2014) “The Great Kapok Tree” was written by Lynne Cherry in response to the murder of Brazilian environmental activist Chico Mendes, who was assassinated by a rancher in 1988 in Brazil. Mendes’ murder was a significant international incident galvanizing support for environmental activists working to protect the Amazon forest.
On babies and motherhood: how giant armadillos are surprising scientists (photos)
(07/01/2014) Until ten years ago scientist's knowledge of the reproductive habits of the giant armadillo— the world's biggest— were basically regulated to speculation. But a long-term research project in the Brazilian Pantanal is changing that: last year researchers announced the first ever photos of a baby giant armadillo and have since recorded a second birth from another female.
New report: illegal logging keeps militias and terrorist groups in business
(06/30/2014) Released last week by the United Nations Environment Programme (UNEP) during the first United Nations Environment Assembly in Nairobi, Kenya, a new report found that together with other other illicit activities such as poaching, illegal deforestation is one of the top money-makers for criminal groups like Boko Haram and Al-Shabaab.
Brazil should convert pasture, not cerrado for biofuel crops
(06/25/2014) If Brazil wants to respect its commitment to reducing greenhouse gas emissions it should target low productivity cattle pasture rather than native cerrado for biofuel crops like sugar cane, argues a new paper published in Nature Climate Change.
Using Google Earth to protect uncontacted tribes in the Amazon rainforest
(06/19/2014) In 2008, images of an uncontacted tribe in the Amazon rainforest in Brazil created ripples. With bodies painted in bright colors, members of the tribe aimed their arrows at a Brazilian government plane flying overhead, occupants of which were attempting to photograph the tribe to prove their existence. Now, a new study has found another way to survey such tribes safely and remotely—using satellite images.
Feather forensics: scientist uses genes to track macaws, aid bird conservation
(06/17/2014) When a massive road project connected the ports of Brazil to the shipping docks of Peru in 2011, conservationists predicted widespread impacts on wildlife. Roads are a well-documented source of habitat fragmentation, interfering with access to available habitat for many terrestrial and tree-dwelling species. However, it wasn’t clear whether or not birds are able to fly over these barriers.
Next big idea in forest conservation? Learning from innovations to make REDD+ work
(06/12/2014) A scientist at the Center for International Forestry Research (CIFOR) in Brazil, Dr. Amy Duchelle coordinates research on the effectiveness, efficiency, equity, and co-benefits of REDD+ initiatives at the sub-national level in Latin America as part of CIFOR's Gloal Comparative Study on REDD+.
Tropical nations make progress in slowing deforestation
(06/10/2014) Efforts to slow destruction of tropical forests seem to be paying off in a number of countries, argues a new report published by the Union of Concerned Scientists (UCS).
In cutting deforestation, Brazil leads world in reducing emissions
(06/05/2014) Brazil's success in reducing deforestation in the world's largest rainforest has been much heralded, but progress may stall unless farmers, ranchers and other land users in the region are provided incentives to further improve the environmental sustainability of their operations, argues a study published this week in the journal Science.
Intact Amazon forests show possible signs of global warming impact
(06/04/2014) Climate change may be taking a hidden toll on intact rainforests in the heart of the Amazon, finds a new study based on 35 years of observations. The research, published in the journal Ecology, focused on the ecological impacts of fragmentation but unexpectedly found changes in the control forests.
Logging, fires take a hidden toll on Amazon rainforest
(05/28/2014) Selective logging and small sub-canopy fires are degrading vast areas of rainforest across the Brazilian Amazon, contributing to largely hidden carbon emissions, argues a study published today in Global Change Biology. The research found stark differences in carbon storage between primary forests, selectively logged forests, logged and burned forests, and regrowing or secondary forests.
Happy Amazon: $215 million raised for world's largest protected area network
(05/21/2014) By all standards the Amazon Region Protected Areas (ARPA) program is gargantuan: the network includes over 90 parks, covers 51 million hectares, and comprises 15 percent of Brazil's Amazon. But protecting an area bigger than Spain isn't cheap or easy. Today, a broad coalition of government donors and private funders have announced $215 million to secure ARPA over the next 25 years.
Greenpeace: Timber laundering rampant in the Brazilian Amazon
(05/18/2014) A two-year investigation by Greenpeace has revealed the extent of timber laundering in two major Brazilian Amazon states: Pará and Mato Grosso. The report, published last week, suggests that fraud is widespread in the Brazilian timber industry. Loggers are using loopholes and outright deception to game regulations that aim to reduce the environmental impact of timber extraction.
New report reveals human rights abuses by corporations, governments in the Amazon
(05/14/2014) Regnskogfondet (the Rainforest Foundation of Norway) recently released a 52-page report that gives an in-depth account of the conflicts activists and indigenous peoples (IPs) are having with corporations and governmental agencies. It relays a situation that does not look good.
Uncovering the impact of big banks on the Amazon
(05/13/2014) Mongabay.org announces up to $30,000 environmental reporting grant: The Brazilian Development Bank & The Amazon. In recent years the Brazilian Development Bank BNDES as emerged as a goliath financier of large-scale energy and infrastructure development in the Amazon and elsewhere in South America. But as projects have mushroomed across the continent, so have the social and environmental impacts.
Not unique to humans: marmoset shows compassion for dying mate (VIDEO)
(05/07/2014) For the first time, researchers have observed an adult marmoset comforting a dying adult family member, behavior that was previously thought to be unique only to humans and chimpanzees. Researchers observed this behavior between a mated pair of common marmosets (Callithrix jacchus) in Brazil, and describe the event in a paper and video published in the journal Primates.
It's in the genes: researchers use DNA to learn about tapir behavior
(05/06/2014) Tapirs are notoriously hard to find and directly observe in the wild. Because of this, little is known about how species behave in their natural habitats. But in a study published in PLOS ONE, researchers found a way around this complication by using tapir DNA to shed light on their behavior.

3M linked to deforestation in Brazil, Canada, Europe, and U.S., says NGO
(04/29/2014) A new report from activist group, ForestEthics, alleges that U.S. company, 3M, supplies many of its products from endangered forests around the world. The NGO links 3M's masking tape and sandpaper to caribou habitat in the boreal forests of Canada, Scotch-Brite sponges to a controversial paper mill in Brazil, and those ubiquitous Post-it Notes to allegedly poor logging practices in the U.S.
Intensifying cattle production in Brazil could cut global deforestation emissions 25%, says study
(04/28/2014) Brazil could reduce more than a quarter of emissions linked to deforestation worldwide by intensifying cattle production in the Amazon, argues a new study published in the journal Proceedings of the National Academy of Sciences.
Next big idea in forest conservation? Crowdsourced forest monitoring
(04/25/2014) In the Brazilian Amazon, deforestation alerts are being submitted via smartphones. On the ground technicians send alerts to a database stored in 'the cloud.' This information is added to maps, which, along with satellite imagery, are used to inform law enforcement. And the speed of this process is getting real results.
The beef with beef: how 12 strategies could drastically cut agricultural emissions
(04/25/2014) Eating less beef, cutting food waste, and utilizing farm landscapes to sequester carbon are three ways a new report suggests the world could rapidly tackle agricultural emissions. Currently, global agriculture accounts for nearly a fifth of the world's greenhouse gas emissions when agriculturally-linked deforestation is included.
Brazil's new Forest Code a mixed bag for native ecosystems
(04/24/2014) The revised Forest Code passed into law by Brazil in 2012 could authorize conversion of 400,000 square miles of native grassland for industrial agriculture, while granting amnesty for deforesters in the Amazon rainforest, argues a policy piece published this week in the journal Science.
Brazil to test drones in monitoring the Amazon rainforest

Nearly a thousand environmental activists murdered since 2002
(04/15/2014) At least 908 people were murdered for taking a stand to defend the environment between 2002 and 2013, according to a new report today from Global Witness, which shows a dramatic uptick in the murder rate during the past four years. Notably, the report appears on the same day that another NGO, Survival International, released a video of a gunman terrorizing a Guarani indigenous community in Brazil.
Emissions from rainforest logging average 16% of those from deforestation
(04/08/2014) Carbon emissions from selective logging operations in tropical rainforests are roughly a sixth of those from outright forest clearing, finds a new study that evaluated 13 forestry concessions in six countries. The study analyzed carbon losses from elements of logging operations, including timber extraction, collateral damage to surrounding vegetation, and logging infrastructure like roads and skid trails.
Will yellow fever drive brown howler monkeys to extinction in Argentina?
(04/04/2014) The brown howler monkey is listed as Critically Endangered in Argentina, where a small number persist in the northeastern portion of the country. Although habitat loss and other human impacts have contributed to the populations’ decline, a new report indicates that yellow fever outbreaks in the region are primarily to blame.
Revealed for the first time: the surprising biodiversity of algae 'reefs'
(03/28/2014) Most people are familiar with coral reefs, but very few have ever heard of their algal equivalent – rhodolith beds. Yet, these structures provide crucial habitat for many marine species. In the first study of its kind, published in mongabay.com’s Tropical Conservation Science, researchers unveil just how important these beds are for bottom-dwelling organisms, and the species that depend on them.
Next big idea in forest conservation? Quantifying the cost of forest degradation
(03/27/2014) How much is a forest really worth? And what is the cost of forest degradation? These values are difficult to estimate, but according to Dr. Phillip Fearnside, we need to do a better job. For nearly forty years, Fearnside has lived in Amazonia doing ecological research, looking at the value of forests in terms of environmental or ecosystem services such as carbon storage, water cycling, and biodiversity preservation. Fearnside then works to convert these services into a basis for sustainable development for rural populations.
Controversial Amazon dams may have exacerbated biblical flooding
(03/16/2014) Environmentalists and scientists raised howls of protest when the Santo Antônio and Jirau Dams were proposed for the Western Amazon in Brazil, claiming among other issues that the dams would raise water levels on the Madeira River, potentially leading to catastrophic flooding. It turns out they may have been right: last week a federal Brazilian court ordered a new environmental impact study on the dams given suspicion that they have worsened recent flooding in Brazil and across the border in Bolivia.
Sharp jump in deforestation when Amazon parks lose protected status
(03/01/2014) Areas that have had their protected status removed or reduced have experienced a sharp increase in forest loss thereafter, finds a new study published by Imazon, a Brazilian NGO.
Is Brazil's epic drought a taste of the future?
(02/25/2014) With more than 140 cities implementing water rationing, analysts warning of collapsing soy and coffee exports, and reservoirs and rivers running precipitously low, talk about the World Cup in some parts of Brazil has been sidelined by concerns about an epic drought affecting the country's agricultural heartland.
Two new wasp species found hidden in museum collections
(02/24/2014) Scientists have identified two new wasp species, years after the specimens were first collected from the wild. The two new species, Abernessia prima and Abernessia capixaba, belong to the rare pompilid genus Abernessia, and are believed to be endemic to Brazil. They made the discovery while examining spider wasp collections from museums in Brazil and Denmark, and published their findings in the journal ZooKeys.
Helping the Amazon's 'Jaguar People' protect their culture and traditional wisdom
(02/11/2014) Tribes in the Amazon are increasingly exposed to the outside world by choice or circumstance. The fallout of outside contact has rarely been anything less than catastrophic, resulting in untold extinction of hundreds of tribes over the centuries. For ones that survived the devastation of introduced disease and conquest, the process of acculturation transformed once proud cultures into fragmented remnants, their self-sufficiency and social cohesion stripped away, left to struggle in a new world marked by poverty and external dependence
Photos: mass turtle hatching produces over 200,000 babies
(02/11/2014) Biologists recently documented one of nature's least-known, big events. On the banks of the Purus River in the Brazilian Amazon, researchers witnessed the mass-hatching of an estimated 210,000 giant South American river turtles (Podocnemis expansa). The giant South American river turtle, or Arrau, is the world's largest side-necked turtle and can grow up to 80 centimeters long (nearly three feet).
Brazilian soy industry extends deforestation moratorium
(02/01/2014) Soy traders and producers in the Brazilian Amazon agreed to extend a moratorium on soybeans produced in recently deforested areas for another year, reports Greenpeace.
Next big idea in forest conservation? Connecting forest fragments
(01/31/2014) Dr. Stuart Pimm is an expert in extinctions: why they happen, how fast they happen, and how they can be prevented. Reconnecting forest fragments and avoiding fragmentation, according to Pimm, are among the most crucial things we can do to conserve global biodiversity. His organization SavingSpecies identifies areas at-risk for extinctions and helps local organizations fundraise so they can protect and restore habitats and safeguard biodiversity.
New dolphin discovered in the Amazon surprises scientists
(01/23/2014) Researchers have discovered a new species of river dolphin from the Amazon. Writing in the journal Plos One, scientists led by Tomas Hrbek of Brazil's Federal University of Amazonas formally describe Inia araguaiaensis, a freshwater dolphin that inhabits the Araguaia River Basin. It is the first true river dolphin discovered since 1918.
Rainforest news review for 2013
(12/26/2013) 2013 was full of major developments in efforts to understand and protect the world's tropical rainforests. The following is a review of some of the major tropical forest-related news stories for the year. As a review, this post will not cover everything that transpired during 2013 in the world of tropical forests. Please feel free to highlight anything this post missed via the comments section at the bottom. Also please note that this review focuses only on tropical forests.
Assassination 25 years ago catalyzed movement to protect the Amazon
(12/22/2013) Twenty-five years ago today, Chico Mendes, an Amazon rubber tapper, was shot and killed in front of his family at his home in Acre, Brazil at the age of 44.
Brazilian cattle producers standardize audits to exclude deforestation from supply chain
(12/18/2013) Brazil's largest cattle producers have agreed to standardize and make public their audits as part of an effort to exclude from their supply chains livestock produced via deforestation, reports Greenpeace, which has led a campaign to improve the environmental performance of the sector. The agreement on a standard auditing protocol means that the companies' progress toward eliminating deforestation will now be directly comparable.
Scientists make one of the biggest animal discoveries of the century: a new tapir
(12/16/2013) In what will likely be considered one of the biggest (literally) zoological discoveries of the Twenty-First Century, scientists today announced they have discovered a new species of tapir in Brazil and Colombia. The new mammal, hidden from science but known to local indigenous tribes, is actually one of the biggest animals on the continent, although it's still the smallest living tapir. Described in the Journal of Mammology, the scientists have named the new tapir Tapirus kabomani after the name for 'tapir' in the local Paumari language: Arabo kabomani.
Scientists: well-managed forest restoration benefits both biodiversity and people
(12/16/2013) In November this year, the world was greeted by the dismaying news that deforestation of the Brazilian Amazon jumped 28% in the past year. The year 2013 also holds the dubious distinction of being the first time since humans appeared on the planet, that carbon concentrations in the atmosphere rose to 400 parts per million. A map by Google revealed that Russia, Brazil, the United States, Canada and Indonesia all displayed over 10 million hectares of gross forest loss from 2000-2012, with the highest deforestation rate occurring in Malaysia.
Odd porcupine hugely imperiled by hunting, deforestation
(12/16/2013) The thin-spined porcupine, also known as the bristle-spined rat, is a truly distinct animal: a sort of cross between New World porcupines and spiny rats with genetic research showing it is slightly closer to the former rather than the latter. But the thin-spined porcupine (Chaetomys subspinosus), found only in Brazil's Atlantic Forest, is imperiled by human activities. In fact, a new study in mongabay.com's open access journal Tropical Conservation Science found that the species remains a target for hunters, despite a reputation for tasting terrible.
Top 10 Environmental Stories of 2013
(12/10/2013) 1. Carbon concentrations hit 400ppm while the IPCC sets global carbon budget: For the first time since our appearance on Earth, carbon concentrations in the atmosphere hit 400 parts per million. The last time concentrations were this high for a sustained period was 4-5 million years ago when temperatures were 10 degrees Celsius higher. Meanwhile, in the slow-moving effort to curb carbon emissions, the Intergovernmental Panel on Climate Change (IPCC) crafted a global carbon budget showing that most of the world's fossil fuel reserves must be left untouched if we are to avoid catastrophic climate change.
New mountain porcupine discovered in Brazil (photos)
(12/09/2013) In Brazil's Baturite Mountains, scientists have uncovered a new species of prehensile-tailed porcupine, according to a new paper in Revista Nordestina de Biologia. Dubbed, the Baturite porcupine (Coendou baturitensis), the new species was discovered when scientists noticed significant differences between it and its closest relative, the Brazilian porcupine (Coendou prehensilis). The name prehensile-tailed refers to these porcupines long, mobile tail which they use as a fifth limb to adroitly climb trees.
Humans are not apex predators, but meat-eating on the rise worldwide
(12/05/2013) A new paper in Proceedings of the National Academy of Sciences has measured the "trophic level" of human beings for the first time. Falling between 1 and 5.5, trophic levels refer to where species fit on the food chain. Apex predators like tigers and sharks are given a 5.5 on trophic scale since they survive almost entirely on consuming meat, while plants and phytoplankton, which make their own food, are at the bottom of the scale. Humans, according to the new paper, currently fall in the middle: 2.21. However, rising meat-eating in countries like China, India, and Brazil is pushing our trophic level higher with massive environmental impacts.
Brazil could boost agriculture without destroying forests
(12/03/2013) Brazil could substantially boost its agricultural output while increasing protection of its native ecosystems, finds a new analysis published by the Climate Policy Initiative (CPI), an international think tank.
Scientists discover new cat species roaming Brazil
(11/27/2013) As a family, cats are some of the most well-studied animals on Earth, but that doesn't mean these adept carnivores don't continue to surprise us. Scientists have announced today the stunning discovery of a new species of cat, long-confused with another. Looking at the molecular data of small cats in Brazil, researchers found that the tigrina—also known as the oncilla in Central America—is actually two separate species. The new species has been dubbed Leopardus guttulus and is found in the Atlantic Forest of southern Brazil, while the other Leopardus tigrinus is found in the cerrado and Caatinga ecosystems in northeastern Brazil.
