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.
Saving rainforests by buying them
(04/04/2014) For more than twenty five years, an international non-profit known as the World Land Trust has been working to protect tropical forests through land purchase and partnerships with local groups. Last year, the U.S. arm of the group decided to rebrand itself as the Rainforest Trust to better convey its core mission to the outside world. Since then, the Rainforest Trust has launched its most ambitious project yet: conserving 5.9 million acres of tropical forest in Peru.
Featured video: celebrities speak out for Yasuni
(04/02/2014) A group of celebrities, including recent Academy Award winner Jared Leto, Law and Order's Benjamin Bratt, and Kill Bill's Daryl Hannah, have lent their voices to a new Public Service Announcement to raise signatures to protect Ecuador's Yasuni National Park from oil drilling.
Chile turns to owls to combat fatal disease
(04/01/2014) This year the Hanta virus has already caused 15 deaths in Chile, according to reports in The Santiago Times. It isn't always fatal—the 15 deaths were of a total of 36 cases over six months—but the symptoms are severe. Those affected experience flu-like symptoms, as well as nausea, vomiting, diarrhoea and trouble breathing. But now Chile is using a novel method to fight the disease: owls.
Brief lives linked to Amazon biodiversity
(03/31/2014) The South American Amazon rainforest is renowned for being one of the most biodiverse ecosystems on the planet, boasting an estimated 16,000 different tree species. However, the distribution of these diverse tree species is curiously uneven. What is the reason behind this irregular diversity? According to a new study, the answer lies within short durations between tree generations.
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.
Bizarre, endangered bird discovered in high densities
(03/24/2014) The turkey-sized, noisy, fruit-feasting guans are arguably one of the strangest wildlife sightings in the tropical forests of Central and South America. Ancient animals, these birds are members of the Cracidae family—which also include equally-odd currasows and chachalacas—and are actually distantly related to megapode, or mound-building, birds of Australiasia. A new study in mongabay.com's open-access journal Tropical Conservation Science looks at a particularly endangered guan: the Cauca gaun (Penelope perspicax).
Sloths, moths and algae: a surprising partnership sheds light on a mystery
(03/22/2014) While it spends the majority of its time in the safety of tree canopies, the three-toed sloth regularly places itself in mortal danger by descending to the forest floor to defecate. For years, scientists have been trying to figure out what is driving this peculiar and risky behavior. Now, Jonathan Pauli from the University of Wisconsin-Madison believes his team of researchers has found an important clue to this mystery involving an unusual and beneficial relationship among sloths, moths and algae.
Scientist discovers a plethora of new praying mantises (pictures)
(03/19/2014) Despite their pacific name, praying mantises are ferocious top predators with powerful, grasping forelimbs; spiked legs; and mechanistic jaws. In fact, imagine a tiger that can rotate its head 180 degrees or a great white that blends into the waves and you'll have a sense of why praying mantises have developed a reputation. Yet, many praying mantis species remain little known to scientists, according to a new paper in ZooKeys that identifies an astounding 19 new species from the tropical forests of Central and South America.
Several Amazonian tree frog species discovered, where only two existed before
(03/18/2014) We have always been intrigued by the Amazon rainforest with its abundant species richness and untraversed expanses. Despite our extended study of its wildlife, new species such as the olinguito (Bassaricyon neblina), a bear-like carnivore hiding out in the Ecuadorian rainforest, are being identified as recently as last year. In fact, the advent of efficient DNA sequencing and genomic analysis has revolutionized how we think about species diversity. Today, scientists can examine known diversity in a different way, revealing multiple 'cryptic' species that have evaded discovery by being mistakenly classified as a single species based on external appearance alone.
Mother of God: meet the 26 year old Indiana Jones of the Amazon, Paul Rosolie
(03/17/2014) Not yet 30, Paul Rosolie has already lived a life that most would only dare dream of—or have nightmares over, depending on one's constitution. With the Western Amazon as his panorama, Rosolie has faced off jaguars, wrestled anacondas, explored a floating forest, mentored with indigenous people, been stricken by tropical disease, traveled with poachers, and hand-reared a baby anteater. It's no wonder that at the ripe age of 26, Rosolie was already written a memoir: Mother of God.
Photos: Weird aquatic lizard discovered in mountain streams of Peru
(03/13/2014) A 'new' species of lizard has been described from the cloud forests of Peru's Manu National Park, reports SERNANP, the Peruvian National Park Service.
From theory to deadly reality: malaria moving upslope due to global warming
(03/06/2014) Malaria is a global scourge: despite centuries of efforts to combat the mosquito-borne disease, it still kills between 660,000 to 1.2 million people a year, according to World Health Organization data from 2010. Astoundingly, experts estimate that around 300 million people are infected with the disease every year or about 4 percent of the world's total population. And these stats may only get worse. For years scientists have vigorously debated whether or not malaria will expand as global warming worsens, but a new study in Science lays down the first hard evidence.
Scientists uncover new species of Andean marsupial frog
(03/05/2014) The term marsupial frog sound like a hoax, but, believe it or not, it's real. Recently, herpetologists welcomed a new species, known as Gastrotheca dysprosita and described in the journal Phyllomedusa. Unlike mammal marsupials, which typically carry their young in pouches on their torsos and are found primarily in Australia, the Gastrotheca genus of frogs, which contains 62 species, is found in the Andes region on South America and sport their pouches on their backs (also called a "dorsal brood pouch").
The price of gold: winners and losers in Latin America's mining industry
(03/05/2014) On a Friday afternoon in June, the Plaza de Armas in Cajamarca is pulsing with life. It's winter here, and although thick white clouds hover low in the distance, the sun in this northern Peruvian city is warm. Couples sit on benches facing one another. Kids run in the grass between flowerbeds. Men in suits stride along the perimeter. It's an idyllic day. But signs of something more ominous are not far from sight. On the mountainside overlooking the town the words Nova Conga have been carved into the vegetation. It is a constant reminder that beyond the square, hemmed with international hotels and expensive restaurants, there is another reality.
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.
Traditional palm knowledge at risk of becoming lost forever
(02/21/2014) The humid tropical forests of northwestern South America boast over 140 different palm species (Arecaceae), yet the people who dwell underneath these green canopies and the knowledge they posses remain relatively unknown to modern science. But Rodrigo Cámara-Leret of the Autonomous University of Madrid and his team of researchers are working to change that by documenting and preserving the traditional knowledge of palms before it is forgotten and lost forever.
New $20,000 reporting grant explores benefits of Amazonian protected areas
(02/21/2014) With six Special Reporting Initiatives (SRI) already under way, Mongabay.org is excited to announce a call for applications for its latest journalism grant topic: Amazonian protected areas: benefits for people. The Amazon’s system of protected areas has grown exponentially in the past 25 years. In many South American nations, the mission of protected areas has expanded from biodiversity conservation to improving human welfare. However, given the multiple purposes and diverse management of many protected areas, it is often difficult to measure their effect on human populations.
The making of Amazon Gold: once more unto the breach
(02/19/2014) When Sarah duPont first visited the Peruvian Amazon rainforest in the summer of 1999, it was a different place than it is today. Oceans of green, tranquil forest, met the eye at every turn. At dawn, her brain struggled to comprehend the onslaught of morning calls and duets of the nearly 600 species of birds resounding under the canopy. Today, the director of the new award-winning film, Amazon Gold, reports that "roads have been built and people have arrived. It has become a new wild west, a place without law. People driven by poverty and the desire for a better life have come, exploiting the sacred ground."
Local communities key to saving the Critically Endangered Mexican black howler monkey
(02/14/2014) For conservation initiatives around the world, community involvement is often crucial. An additional challenge is how to conserve species once their habitats have become fragmented. A primatologist in Mexico is bringing these together in a celebration of a Critically Endangered primate species: the Mexican black howler monkey. In 2013 Juan Carlos Serio-Silva was part of a team that not only helped to secure the establishment of a protected area for the Mexican black howler monkey, but also engaged local communities in a week of festivities, dubbed the First International Black Howler Monkey Week.
Featured video: camera traps catch jaguars, anteaters, and a sloth eating clay in the Amazon rainforest
(02/13/2014) These are sights that have rarely been seen by human eyes: a stealthy jaguar, a bustling giant armadillo, and, most amazingly, a sloth slurping up clay from the ground. A new compilation of camera trap videos from Yasuni National Park in the Ecuadorean Amazon shows a staggering array of species, many cryptic and rare.
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
Drought, fire reducing ability of Amazon rainforest to store carbon
(02/06/2014) New research published in Nature adds further evidence to the argument that drought and fire are reducing the Amazon's ability to store carbon, raising concerns that Earth's largest rainforest could tip from a carbon sink to a carbon source.
Gas company to drill in Manu National Park buffer zone, imperiling indigenous people
(02/04/2014) The Peruvian government has approved plans for gas company Pluspetrol to move deeper into a supposedly protected reserve for indigenous peoples and the buffer zone of the Manu National Park in the Amazon rainforest. The approval follows the government rescinding a highly critical report on the potential impacts of the operations by the Culture Ministry (MINCU), the resignation of the Culture Minister and other Ministry personnel, and repeated criticism from Peruvian and international civil society.
Total says it will not drill in any World Heritage Sites
(02/03/2014) One of the world's largest oil and gas companies, Total, has committed to leave the planet's UNESCO World Heritage Sites untouched, according to the United Nations. The UN says the French energy giant has sent written confirmation that it will not explore or extract fossil fuels from any of the world's over 200 natural World Heritage Sites.
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.
287 amphibian and reptile species in Peruvian park sets world record (photos)
(01/28/2014) It's official: Manu National Park in Peru has the highest diversity of reptiles and amphibians in the world. Surveys of the park, which extends from high Andean cloud forests down into the tropical rainforest of the Western Amazon, and its buffer zone turned up 155 amphibian and 132 reptile species, 16 more than the 271 species documented in Ecuador's Yasuní National Park in 2010.
Key highland habitat for rare condor protected in Ecuador
(01/24/2014) Conservationists have acquired a 2,800-ha (7,000-acre) property that completes the acquisition of some 108,000 ha of key Andean Condor habitat in Ecuador.
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.
Spectacular new beetle discovered in French Guiana
(01/21/2014) The discovery of a new, bi-colored beetle species in the lowland rainforest of French Guiana just added a little pizzazz to the ranks of the Pseudomorphini tribe of beetles. With wing cases (elytra) that sport black spots against a rusty red background, the newcomer was dubbed Guyanemorpha spectabilis, or the spectacular Guyane false-form beetle, by entomologist Terry Erwin in the journal ZooKeys.
Red toad discovered in the upper reaches of the Amazon
(01/19/2014) Scientists have described a previously unknown species of toad in the Peruvian Andes.
Court orders logging company to clean up pollution disaster in Chile wetlands
(01/17/2014) Chile is probably best known for its volcanoes, earthquakes and the formidable peaks of the Andes, but as a country that spans 4,300 km (2,670 miles) from top to bottom, it also boasts a huge variety of bird life. And, until recently, it was home to what was thought to be the largest population of black-necked swans (Cygnus melancoryphus) in South America. Not long ago, these swans, as well as 100 other species of rare or vulnerable bird species, could be seen nesting in the Carlos Anwandter Nature Sanctuary in Valdivia, a Ramsar site that covers 12,000 acres in the south of Chile. But in 2004 the swans began to die.
Colombia to protect remote region bordering Venezeula
(01/13/2014) The Colombian government plans to declare a remote area bordering Venezuela a new protected area. Colombian Minister of Environment, Luz Helena Sarmiento, told the El Espectador that President Juan Manuel Santos will declare the Estrella Fluvial de Inirida river area a Ramsar Wetland of International Importance. The designation would give Colombia six Ramsar sites.
Rewilding Chile's savanna with guanacos could increase biodiversity and livestock
(01/06/2014) Local extinctions have occurred across a variety of habitats on every continent, affecting a gamut of species from large predators such as the wolves of North America, to tiny amphibians like the Kihansi spray toad of Tanzania. The long trek toward reversing such extinctions has begun, but it is not without its challenges, both ethical and logistical.
Good news: Refuge for last blue-throated macaws doubles in size in Bolivia
(01/02/2014) A reserve that is home to the world's largest population of the critically endangered blue-throated macaw (Ara glaucogularis) has been more than doubled in size, reports the American Bird Conservancy (ABC), a group that helped fund the expansion.

(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.
Jaguars in Argentine Chaco on verge of local extinction
(12/23/2013) The majestic jaguar (Panthera onca), the largest of the New World cats, is found as far north as the southern states of the US, and as far south as northern Argentina. In the past jaguars ranged 1,500 kilometers (930 miles) further south, but their range has shrunk as habitat loss and human disturbance have increased. Overall, jaguars are classified as Near Threatened by the IUCN, but the level of risk facing jaguars varies by region. Populations in Argentina, at the present-day southern range limit, have previously been identified as some of the most threatened of them all.
New marsupial discovered in Ecuador
(12/20/2013) Researchers working in Ecuador have identified a previously unknown species of shrew-opossum, according to a study recently published in the Journal of Mammalogy. Contrary to its mousey appearance, Caenolestes sangay, named after the national park where it was discovered, is actually a marsupial. The team from Pacific Lutheran University set up more than 100 live traps over 15 nights on the eastern slopes of Andes. In the course of their research they recovered five specimens of the new species, each measuring approximately 10 centimeters (3.9 inches) long.
Top 10 HAPPY environmental stories of 2013
(12/19/2013) China begins to tackle pollution, carbon emissions: As China's environmental crisis worsens, the government has begun to unveil a series of new initiatives to curb record pollution and cut greenhouse emissions. The world's largest consumer of coal, China's growth in emissions is finally slowing and some experts believe the nation's emissions could peak within the decade. If China's emissions begin to fall, so too could the world's.
Using stories to connect people to biodiversity: an interview with Tara Waters Lumpkin, PhD
(12/18/2013) In a world where extinctions are almost commonplace and global warming barely raises an eyebrow, very few of us can return to find the places we grew up in unsullied by development. Sometimes, all that is left of a favorite grove of trees or strip of forest are memories. Through Izilwane: Voices for Biodiversity Project, an online magazine for story-tellers, Tara Waters Lumpkin has succeeded in bringing together more than one hundred "eco-writers" who have shared their memories, highlighted environmental crises in their localities and raised their voices against habitat destruction.
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.
Big data shows tropical mammals on the decline
(12/12/2013) The world's largest remote camera trap initiative—monitoring 275 species in 17 protected areas—is getting some big data assistance from Hewlett-Packard (HP). To date, the monitoring program known as the Tropical Ecology Assessment and Monitoring (TEAM) Network has taken over 1.5 million photos of animals in 14 tropical countries, but conservationists have struggled with how to quickly evaluate the flood of data.
Journalists win environmental news reporting prizes
(12/10/2013) Mongabay's internship program has benefited from the hard work and great environmental reporting of more than 30 writing interns since the program's inception in July 2012. This year, Mongabay asked this pool of contributing authors to submit their most compelling piece out of over 150 articles. The submissions were then reviewed by a panel.
Ecuador's government shuts down indigenous rights organization over oil battle
(12/10/2013) Last Wednesday, the government of Ecuador shutdown the indigenous rights NGO, Fundación Pachamama, in Quito over the group's opposition to oil drilling in indigenous areas. More than a dozen government officials showed up at Pachamama's office with a resolution by the Ministry of Environment that officially dissolved the organization, the first such moved by the government which in June passed an Executive Decree that tightened governmental oversight of the country's NGOs.
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.
