(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.
Gold mine near controversial Belo Monte dam suspended
(11/22/2013) A gold mining project proposed near the Belo Monte dam site in the Amazon rainforest has been suspended by a Brazilian court, reports Reuters.
Why is Amazon deforestation climbing?
(11/17/2013) The 28 percent increase in deforestation in the Brazilian Amazon over last year that was reported this week is bad news, but it is not surprising. It is bad news because the decline in deforestation since 2005 has given us the single largest contribution to climate change mitigation on the planet, far surpassing the reductions in emissions achieved by any Annex 1 country under the Kyoto Protocol. Brazil’s achievement is particularly noteworthy because it did not come at the expense of agricultural production; beef and soybean production continued to grow.
New bat species discovered in Brazil leaves another at risk
(11/15/2013) A team of researchers has discovered a new species of bat in Brazil, which has put a previously known species, Bokermann's nectar bat (Lonchophylla bokermanni), at risk of extinction. Long thought to comprise one species, the bat populations of the Atlantic Forest and the Cerrado – the tropical savannah of Brazil's interior - are in fact distinct from one another, according to a new study in Zootaxa. Scientists now say the Atlantic Forest's population represents a newly described species, which they have dubbed Peracchi's nectar bat (Lonchophylla peracchii).
Deforestation in the Brazilian Amazon jumps 28% in 2013
(11/14/2013) Deforestation in the Brazilian Amazon jumped 28% in 2013 sparking concerns that recent progress in reducing forest loss in the world's largest rainforest may be in danger of reversing. The preliminary data, released Thursday by the Brazilian government, shows that 5,843 square kilometers (2,256 sq miles) of rainforest was cleared across the 'Legal Amazon' between August 1, 2012 and July 31, 2013.
Powered by Google, high resolution forest map reveals massive deforestation worldwide
(11/14/2013) Researchers today released a long-awaited tool that reveals the extent of forest cover loss and gain on a global scale. Powered by Google's massive computing cloud, the interactive forest map establishes a new baseline for measuring deforestation and forest recovery across all of the world's countries, biomes, and forest types. The map has far-reaching implications for efforts to slow deforestation, which accounts for roughly ten percent of greenhouse gas emissions produced by human activities, according to the authors of the paper that describes the tool and details its first findings.
Scientists identify 137 protected areas most important for preserving biodiversity
(11/14/2013) Want to save the world's biodiversity from mass extinction? Then make certain to safeguard the 74 sites identified today in a new study in Science. Evaluating 173,000 terrestrial protected areas, scientists pulled out the most important ones for global biodiversity based on the number of threatened mammals, birds, and amphibians found in the parks. In all they identified 137 protected areas (spread over 74 sites as many protected areas were in the same region) in 34 countries as 'irreplaceable.'
Locally extinct birds in the Amazon slowly flock back to forests when trees regrow
(11/13/2013) Some good news out of the Amazon rainforest: given enough time, deforested land can rebound enough to host bird species that had previously deserted the area, according to a recent study in The Auk. When people abandon deforested land, the rainforest slowly reclaims it. Eventually, birds begin to use the clumps of secondary forest as corridors between thickets of old growth.
Like humans, marmosets are polite communicators
(11/06/2013) Common marmoset monkeys have been described as having human-like conversations according to a team of researchers from the Princeton Neuroscience Institute. Native to Brazil, marmosets are highly social animals, using simple vocalizations in a multitude of situations: during courtship, keeping groups together and defending themselves. They also, according to the study published in Current Biology, exchange cooperative conversations with anyone and everyone - not just with their mates.
Belo Monte dam suspended
(10/29/2013) Construction on Belo Monte, Brazil's largest dam, was again halted by a federal court due to concerns over its license, reports Amazon Watch, an NGO that is mobilizing opposition to the project.
50,000 km of roads built across Brazilian Amazon in 3 years
(10/29/2013) Roads are rapidly expanding across the Brazilian Amazon opening up once remote rainforests to loggers, miners, ranchers, farmers, and land speculators, finds a new study published in the journal Regional Environmental Change.
Illegal logging remains rampant in Brazil
(10/23/2013) Illegal logging remains pervasive in the Brazilian state of Pará, finds an assessment released Monday by Imazon.
Scientist splits Amazonian giants into separate species
(10/23/2013) It's hard to mistake an arapaima for anything else: these massive, heavily-armored, air-breathing fish (they have to surface every few minutes) are the megafauna of the Amazon's rivers. But despite their unmistakability, and the fact that they have been hunted by indigenous people for millennia, scientists still know relatively little about arapaima, including just how many species there are. Since the mid-Nineteenth Century, scientists have lumped all arapaima into one species: Arapaima gigas. However, two recent studies in Copeia split the arapaimas into at least five total species—and more may be coming.
40% of Brazil's rural area owned by 1.4% of landholders
(10/16/2013) Forty percent of the 509 million hectares of land classified as 'rural property' in Brazil is owned by 1.4 percent of rural households, finds a new analysis conducted by a group of Brazilian NGO's.
Mammal-watching: one man's obsession to see the world's mammals
(10/16/2013) There are more than 5,000 different mammal species across the globe, but with this number being dwarfed by the 10,000 bird species, it is little wonder that bird-watching has become the most common wildlife watching hobby in the world. While there are thousands of websites dedicated to ornithology enthusiasts, with information detailing the best places to see particular species and how to find them, similar resources about mammals remain scarce.
Has Brazil turned against its progressive environmental policies?
(09/30/2013) Last year, Brazil rolled back crucial parts of its landmark Forestry Code, potentially opening vast tracts of forest for destruction; it is also moving ahead on a number of Amazon dams, including the infamous Belo Monte, despite international condemnation and conflict with indigenous people. Meanwhile, a new law under consideration proposes allowing large-scale mining in protected areas. Given this a new paper in mongabay.com's open access journal Tropical Conservation Science argues that Brazil has thrown off its once admired mantle of environmental legislation, imperiling hundreds of thousands of species in the most biodiverse country on Earth.
New prioritization for Brazil's threatened mammals pushes little known primates and rodents to the top
(09/30/2013) Scientists have applied a species prioritization scheme to Brazil's diverse mammals to deduce which species should become the focus of conservation efforts over the next few years in a new paper published in mongabay.com's open-access journal Tropical Conservation Science.
Judge halts construction of Amazon dam on Brazil's Teles Pires river

Brazil's satellite data suggests rise in Amazon deforestation over past year
(09/12/2013) Deforestation in the Brazilian Amazon appears to have risen significantly over the past year, according to data released by the country's space agency, INPE. Data aggregated from INPE's monthly deforestation alert system shows a 34 percent rise for the 12 months ended July 31, 2013 relative to the year-earlier period.
Scientists discover that threatened bird migrates entirely within Amazon Basin
(09/11/2013) When one thinks of bird migrations, it's usually a north-south route that follows seasonal climates. But researchers in the Amazon have tracked, for the first time, a largely-unknown long-distance migration that sticks entirely to the Amazon Basin. Using satellite telemetry, scientists tracked a pair of Orinoco geese (Neochen jubata) from Peru and a male from Western Brazil, who both migrated to the Llanos de Moxos, a vast savanna and Amazonian watershed in Bolivia. The research has shown that the Orinoco geese—which breeds in both Peru and Brazil—depends on wetlands in the Llanos de Moxos for much of the year.
Brazil establishes 2 Amazon parks covering 2.4m acres
(09/10/2013) The Brazilian government has designated 952,000 hectares of remote public land in the Amazon as two new protected areas.
Amazon rainforest tribe sells REDD+ credits to Brazilian cosmetics giant
(09/10/2013) The Paiter-Suruí, a rainforest tribe that in June became the first indigenous group to generate REDD+ credits under the Verified Carbon Standard (VCS), has now closed their first deal. As reported by Ecosystem Marketplace, Brazilian cosmetics giant Natura Cosméticos has purchased 120,000 tons of carbon offsets from the the Surui Forest Carbon Project in Rondônia, Brazil.

(09/02/2013) In a world first, scientists have captured images and video of a boa constrictor attacking and devouring whole a femle howler monkey, one of the largest new world primates weighing in at around 4 kilograms (8.8 pounds). The rare predation event was recorded in a tiny forest fragment (2.5 hectares) in the Brazilian state of Rondonia by Erika Patricia Quintino, a PhD student at the Pontifical Catholic University of Rio Grande do Sul.
85% of Brazilian leather goes to markets sensitive to environmental concerns
(08/22/2013) Around 40% of beef and 85% of leather production serve markets that are potentially sensitive to environmental concerns, providing a partial explantation as to why Brazilian producers have made recent commitments to reducing deforestation for cattle production, finds a new study published in Tropical Conservation Science.
Pesticide problems in the Amazon
(08/21/2013) As the world’s population increases and agricultural frontiers expand into native tropical habitats, researchers are working furiously to understand the impacts on tropical forests and global biodiversity. But one obvious impact has been little studied in these agricultural frontiers: pesticides. However a new study in the journal Philosophical Transactions of The Royal Society B seeks to shine a light on the problem.
With deforestation rising, Brazil sends more police to the Amazon
(08/19/2013) With deforestation pacing more than 90 percent ahead of last year's rate according to an estimate released today, Brazil said it has increased the number of environmental inspectors in the Amazon rainforest.
Brazil's military takes on illegal loggers to protect nearly-extinct tribe
(07/18/2013) Brazil has launched a military campaign to evict illegal loggers working from the fringes of an indigenous reserve home to the Awá people, reports Survival International. Inhabiting the Amazon rainforest in northeastern Brazil, only around 450 Awá, also known as Guajá, survive today, and around a quarter of these have chosen voluntary isolation.

60 big cats killed in Brazilian parks in last two years
(06/24/2013) At least 60 big cats have been killed within national protected areas in Brazil during the past two years according to a recent survey published in mongabay.com's open access journal Tropical Conservation Science. The report, which focuses on jaguar (Panthera onca) and puma (Puma concolor) populations, within Brazilian protected areas shows that reserve management and use restrictions impact the level of big cat hunting.
On guard: protecting wildlife in a heavily hunted Brazilian forest
(06/24/2013) The Brazilian government offers tax relief to landowners who set aside areas for preservation. While this has expanded the system of private ecological reserves considerably, the Brazilian government currently lacks funding to enforce the protection of these lands from threats such as hunting, leaving the responsibility to the landowners.
Bird extravaganza: scientists discover 15 new species of birds in the Amazon
(06/12/2013) From 2000-2009, scientists described on average seven new bird species worldwide every year. Discovering a new bird is one of the least common of any species group, given that birds are highly visible, mobile, and have been scrutinized for centuries by passionate ornithologists and birders. But descriptions this year already blows away the record year over the last decade (in 2001 when nine new birds were described): scientists working in the southern Amazon have recorded an incredible 15 new species of birds according to the Portuguese publication Capa Aves. In fact, this is the largest group of new birds uncovered in the Brazilian in the Amazon in 140 years.
11,000 barrels of oil spill into the Coca River in the Amazon
(06/12/2013) On May 31st, a landslide ruptured an oil pipeline in Ecuadorean Amazon, sending around 11,000 barrels of oil ( 420,000 gallons) into the Coca River. The oil pollution has since moved into the larger Napo River, which borders Yasuni National Park, and is currently heading downstream into Peru and Brazil. The spill has occurred in a region that is notorious for heavy oil production and decades of contamination, in addition to resistance and lawsuits by indigenous groups.
Brazil may lift ban on Amazon ethanol expansion
(06/09/2013) In coming weeks Brazil will vote on a bill that would lift a ban on sugar cane mills across a large extent of the Amazon region, sparking fears that ethanol production could drive new deforestation and tarnish the country's image as an attractive source biofuels for environmentally-conscious markets,
Brazil's GHG emissions fall 39% since 2005, now 10% below 1990 levels
(06/06/2013) Brazil’s greenhouse-gas emissions dropped 39 percent between 2005 and 2010, largely due to a reduction in deforestation, reports an inventory released yesterday by the Brazilian government.
Brazil touts progress in reducing deforestation, but fails to note recent jump in clearing
(06/05/2013) Today in a press release for the U.N.'s World Environment Day, the Brazilian government highlighted a sharp drop in deforestation since 2012. The trouble is, the South American superpower failed to acknowledge what appears to be a sharp rise in Amazon forest loss since last year, reports Greenpeace.
Loss of big fruit-eating birds impacting trees in endangered rainforests

Two new arachnids discovered in Brazilian caves (photos)
(05/29/2013) Scientists have discovered two new species of short-tailed whipscorpions (in the order Schizomida) in limestone caves in Brazil, according to a new paper published in PLoS ONE. The new species—dubbed Rowlandius ubajara and Rowlandius potiguara—add new knowledge to a group of arachnids that is little known in South America outside of the Amazon.
World's largest tropical park may have protected status revoked
(05/21/2013) Tumucumaque National Park, a sprawling reserve that covers 38,874 square kilometers (15,010 sq mi) of rainforest in northeastern Brazil, may see its protected status revoked due to insufficient consultation with local municipalities prior to its creation.
Deforestation in the Brazilian Amazon pacing 88% higher than last year's rate
(05/18/2013) Satellite analysis by a Brazil-based NGO indicates that deforestation in the Brazilian Amazon continues to pace well ahead of last year, when the government passed a weakened version of its law governing use of forest lands.
Amazon's flood/drought cycle becoming more extreme, less predictable
(05/14/2013) The Amazon River's hydrological cycle has become more extreme over the past two decades with increasing seasonal precipitation across much of the basin despite drier conditions in the southern parts of Earth's largest rainforest, finds a new study published in Geophysical Research Letters. The research analyzed monthly Amazon River discharge at Óbidos, a point that drains 77 percent of the Amazon Basin, and compared it with regional precipitation patterns.
Deforestation will undercut effectiveness of rainforest dams
(05/13/2013) Deforestation may significantly decrease the hydroelectric potential of tropical rainforest regions, warns a new study published in Proceedings of the National Academy of Science. The study, used climate, hydrological, and land use models to forecast the impact of potential forest loss on hydropower generation on the Xingu River, a major tributary of the Amazon where the world's third largest dam — Belo Monte — is currently under construction.
Continued deforestation in the Amazon may kill Brazil's agricultural growth
(05/09/2013) Continuing deforestation in the Amazon rainforest could undermine agricultural productivity in the region by reducing rainfall and boosting temperatures, warns a new study published in the journal Environmental Research Letters.
Brazil's satellite monitoring reduced Amazon deforestation by 60,000 sq km in 5 years
(05/08/2013) Brazil's advanced satellite monitoring system, coupled with increased law enforcement, was responsible for nearly 60 percent of the 101,000 square kilometer-drop in deforestation observed between 2007 and 2011, argues a new study published an international think tank.
Debate heats up over California's plan to reduce emissions via rainforest protection
(05/07/2013) As the public comment period for California's cap-and-trade program draws to a close, an alliance of environmental activists have stepped up a heated campaign to keep carbon credits generated by forest conservation initiatives in tropical countries out of the scheme. These groups say that offsets generated under the so-called Reducing Emissions from Deforestation and Degradation (REDD+) mechanism, will undermine efforts to cut emissions as home, while potentially leading to abuses abroad. However supporters of forest conservation-based credits say the program may offer the best hope for saving the world's beleaguered rainforests, which continue to fall at a rate of more than 8 million hectares per year.
