News articles on Amazon biodiversity
Mongabay.com news articles on Amazon biodiversity in blog format. Updated regularly.
(03/20/2014) A new multimedia feature story by Brazilian environmental news group, ((o))eco, highlights the ongoing debate over Yasuni National Park in Ecuador, arguably the most biodiverse place on the planet.
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.
Amazon trees super-diverse in chemicals
(03/03/2014) In the Western Amazon—arguably the world's most biodiverse region—scientists have found that not only is the forest super-rich in species, but also in chemicals. Climbing into the canopy of thousands of trees across 19 different forests in the region—from the lowland Amazon to high Andean cloud forests—the researchers sampled chemical signatures from canopy leaves and were surprised by the levels of diversity uncovered.
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.
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.
High-living frogs hurt by remote oil roads in the Amazon
(01/14/2014) Often touted as low-impact, remote oil roads in the Amazon are, in fact, having a large impact on frogs living in flowers in the upper canopy, according to a new paper published in PLOS ONE. In Ecuador's Yasuni National Park, massive bromeliads grow on tall tropical trees high in the canopy and may contain up to four liters of standing water. Lounging inside this micro-pools, researchers find a wide diversity of life, including various species of frogs. However, despite these frogs living as high as 50 meters above the forest floor, a new study finds that proximity to oil roads actually decreases the populations of high-living frogs.
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.
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.
Could camera trap videos galvanize the world to protect Yasuni from oil drilling?
(11/07/2013) Even ten years ago it would have been impossible to imagine: clear-as-day footage of a jaguar plodding through the impenetrable Amazon, or a bicolored-spined porcupine balancing on a branch, or a troop of spider monkeys feeding at a clay lick, or a band of little coatis racing one-by-one from the dense foliage. These are things that even researchers who have spent a lifetime in the Amazon may never see. Now anyone can: scientists at the Tiputini Biodiversity Station in Ecuador's Yasuní National Park have recently begun using camera trap videos to take movies of animals few will ever view in their lifetimes. The videos—following years of photo camera trapping—provide an intimate view of a world increasingly threatened by the oil industry.
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.
Featured video: 22-year-old produces documentary on the Peruvian Amazon
(10/15/2013) Spending a year on the Tambopata River in Peru's deep Amazon, allowed 22-year-old Tristan Thompson, to record stunning video of the much the region's little seen, and little known, wildlife. Thompson, a student at the University of the West of England, has turned his footage into a new documentary An Untamed Wilderness that not only gives viewers an inside look at the world's greatest forests, but also records the secretive behavior of many species, including howler monkeys, aracaris, leaf-cutter ants, hoatzin, and giant river otters.
Over 100 scientists warn Ecuadorian Congress against oil development in Yasuni
(10/03/2013) Over 100 scientists have issued a statement to the Ecuadorian Congress warning that proposed oil development and accompanying roads in Yasuni National Park will degrade its "extraordinary biodiversity." The statement by a group dubbed the Scientists Concerned for Yasuni outlines in detail how the park is not only likely the most biodiverse ecosystems in the western hemisphere, but in the entire world. Despite this, the Ecuadorian government has recently given the go-ahead to plans to drill for oil in Yasuni's Ishpingo-Tambococha-Tiputini (ITT) blocs, one of most remote areas in the Amazon rainforest.
Yasuni could still be spared oil drilling
(08/26/2013) When Ecuadorean President, Rafael Correa, announced on August 15th that he was abandoning an innovative program to spare three blocs of Yasuni National Park from oil drilling, it seemed like the world had tossed away its most biodiverse ecosystem. However, environmental groups and activists quickly responded that there may be another way to keep oil companies out of Yasuni's Ishpingo-Tambococha-Tiputini (ITT) blocs: a national referendum.
Amazonian students help monitor threatened frog populations
(07/01/2013) According to the International Union for Conservation of Nature, amphibians are the most threatened group of animals on Earth: currently around 30 percent of the world's amphibians are listed as threatened with extinction. However this percentage doesn't include those species about which too little is known to evaluate (26 percent). Amphibians face many threats but two of the largest are habitat loss and the lethal chytrid fungus, which has rapidly spread worldwide and is likely responsible for numerous extinctions. But conservationists are coming up with innovative and creative ways to keep amphibians from disappearing, including a program from the Detroit Zoological Society (DZS) that is working with students in the Peruvian Amazon to monitor frog populations.
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.
Crazy cat numbers: unusually high jaguar densities discovered in the Amazon rainforest
(05/16/2013) Jaguars (Panthera onca) are the biggest cat in the Americas and the only member of the Panthera genus in the New World; an animal most people recognize, the jaguar is also the third largest cat in the world with an intoxicatingly dangerous beauty. The feline ranges from the harsh deserts of southern Arizona to the lush rainforests of Central America, and from the Pantanal wetlands all the way down to northern Argentina. These mega-predators stalk prey quietly through the grasses of Venezuelan savannas, prowl the Atlantic forests of eastern Brazil, hunt along the river of the Amazon, and even venture into lower parts of the Andes.
NGO: conflict of interests behind Peruvian highway proposal in the Amazon
(05/16/2013) As Peru's legislature debates the merits of building the Purús highway through the Amazon rainforest, a new report by Global Witness alleges that the project has been aggressively pushed by those with a financial stake in opening up the remote area to logging and mining. Roads built in the Amazon lead to spikes in deforestation, mining, poaching and other extractive activities as remote areas become suddenly accessible. The road in question would cut through parts of the Peruvian Amazon rich in biodiversity and home to indigenous tribes who have chosen to live in "voluntary isolation."
Amazon: the world's greatest rainforest or internet giant?
(04/25/2013) When you see the word "Amazon", what's the first thing that springs to mind—the world's biggest forest, the longest river or the largest internet retailer—and which do you consider most important? These questions have risen to the fore in an arcane, but hugely important, debate about how to redraw the boundaries of the internet. Brazil and Peru have lodged objections to a bid made by the US e-commerce giant for a prime new piece of cyberspace: ".amazon".
Indigenous group: Brazil using military to force Amazon dams
(04/08/2013) An Amazonian community has threatened to "go to war" with the Brazilian government after what they say is a military incursion into their land by dam builders. The Munduruku indigenous group in Para state say they have been betrayed by the authorities, who are pushing ahead with plans to build a cascade of hydropower plants on the Tapajós river without their permission.
Jaguars, tapirs, oh my!: Amazon explorer films shocking wildlife bonanza in threatened forest
(02/19/2013) Watching a new video by Amazon explorer, Paul Rosolie, one feels transported into a hidden world of stalking jaguars, heavyweight tapirs, and daylight-wandering giant armadillos. This is the Amazon as one imagines it as a child: still full of wild things. In just four weeks at a single colpa (or clay lick where mammals and birds gather) on the lower Las Piedras River, Rosolie and his team captured 30 Amazonian species on video, including seven imperiled species. However, the very spot Rosolie and his team filmed is under threat: the lower Las Piedras River is being infiltrated by loggers, miners, and farmers following the construction of the Trans-Amazon highway.
Gold mine approved in French Guiana's only national park
(01/15/2013) Tensions have risen in the small Amazonian community of Saül in French Guiana after locals discovered that the French government approved a large-scale gold mining operation near their town—and inside French Guiana's only national park—against their wishes. Run by mining company, Rexma, locals and scientists both fear that the mine would lead to deforestation, water pollution, and a loss in biodiversity for a community dependent on the forest and ecotourism.
Unique program to leave oil beneath Amazonian paradise raises $300 million
(11/26/2012) The Yasuni-ITT Initiative has been called many things: controversial, ecological blackmail, revolutionary, pioneering, and the best chance to keep oil companies out of Ecuador's Yasuni National Park. But now, after a number of ups and downs, the program is beginning to make good: the Yasuni-ITT Initiative has raised $300 million, according to the Guardian, or 8 percent of the total amount needed to fully fund the idea.
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).
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).
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.
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.
Can loggers be conservationists?
(05/10/2012) Last year researchers took the first ever publicly-released video of an African golden cat (Profelis aurata) in a Gabon rainforest. This beautiful, but elusive, feline was filmed sitting docilely for the camera and chasing a bat. The least-known of Africa's wild cat species, the African golden cat has been difficult to study because it makes its home deep in the Congo rainforest. However, researchers didn't capture the cat on video in an untrammeled, pristine forest, but in a well-managed logging concession by Precious Woods Inc., where scientist's cameras also photographed gorillas, elephants, leopards, and duikers.
Amazon plant yields miracle cure for dental pain
(03/14/2012) The world may soon benefit from a plant long-used by indigenous people in the Peruvian Amazon for toothaches, eliminating the need for local injections in some cases. Researchers have created a medicinal gel from a plant known commonly as spilanthes extract (Acmella Oleracea), which could become a fully natural alternative to current anesthetics and may even have a wide-range of applications beyond dental care.
Innovative program seeks to safeguard Peruvian Amazon from impacts of Inter-Oceanic Highway
(03/06/2012) Arbio was begun by Michel Saini and Tatiana Espinosa Q. in the Peruvian Amazon region of Madre de Dios. The project focuses on a protective response to the increased encroachment and destructive land use driven by development. The recent construction of the Inter-Oceanic Highway in the Madre de Dios area presents an enormous threat to forest biodiversity. Arbio provides opportunities to help establish a buffer zone near the road to limit intrusive agricultural and deforestation activities.
Tourism for biodiversity in Tambopata
(02/27/2012) Research and exploration in the Neotropics are extraordinary, life-changing experiences. In the past two decades, a new generation of collaborative projects has emerged throughout Central and South America to provide access to tropical biodiversity. Scientists, local naturalists, guides, students and travelers now have the chance to mingle and share knowledge. Fusion programs offering immersion in tropical biology, travel, ecological field work, and adventure often support local wilderness preservation, inspire and educate visitors.
Majority of protected tropical forests "empty" due to hunting
(02/08/2012) Protected areas in the world's tropical rainforests are absolutely essential, but one cannot simply set up a new refuge and believe the work is done, according to a new paper in Bioscience. Unsustainable hunting and poaching is decimating tropical forest species in the Amazon, the Congo, Southeast Asia, and Oceana, leaving behind "empty forests," places largely devoid of any mammal, bird, or reptile over a few pounds. The loss of such species impacts the whole ecosystems, as plants lose seed dispersers and the food chain is unraveled.
Fungus from the Amazon devours plastic
(02/02/2012) Students from Yale University have made the amazing discovery of a species of fungus that devours one of the world's most durable, and therefore environmentally troublesome, plastics: polyurethane. The new species of fungus, Pestalotiopsis microspora, is even able to consume polyurethane in zero-oxygen (anaerobic) conditions, which would be important in eating plastics in the deep dark layers of landfills where little sunlight, water, or oxygen is found.
Photo of the day: super-abundance of life found in Amazon park
(02/02/2012) Surveying a little-explored park in the Peruvian Amazon has paid off in dividends: researchers with the Wildlife Conservation Society (WCS) have cataloged 365 species that had not yet been recorded in Bahuaja Sonene National Park. The never-before recorded species included two bats, thirty birds, and over two hundred butterflies and moths.
Photo of the Day: Critically Endangered brown spider monkey discovered in park
(01/26/2012) Researchers with The Wildlife Conservation Society (WCS) and Colombia’s National Parks Unit have located at least two individuals of brown-spider monkey (Ateles hybridus) in Colombia's Selva de Florencia National Park. The discovery is important because its the only known population of this particular subspecies (Ateles hybridus brunneus) in a protected area.
Photos: 46 new species found in little-explored Amazonian nation
(01/25/2012) South America's tiniest independent nation still hides a number of big surprises: a three week survey to the sourthern rainforests of Suriname found 46 potentially new species and recorded nearly 1,300 species in all. Undertaken by Conservation International's (CI) Rapid Assessment Program (RAP) the survey found new species of freshwater fish, insects, and a new frog dubbed the "cowboy frog" for the spur on its heel. While Suriname may be small, much of its forest, in the Guyana Shield region of the Amazon, remains intact and pristine. The Food and Agriculture Organization (FAO) estimates that 91 percent of Suriname is covered in primary forests, however this data has not been updated in over two decades.
Geology has split the Amazon into two distinct forests
(01/19/2012) The common view of the Amazon is that it is one massive, unbroken forest. This impression is given by maps which tend to mark the Amazon by a large glob of green or even by its single name which doesn't account for regional changes. Of course, scientists have long recognized different ecosystems in the Amazon, most especially related to climate. But a new study in the Journal of Biogeography has uncovered two distinct forest ecosystems, sharply divided, caused by million of years of geologic forces.
Ecuador makes $116 million to not drill for oil in Amazon
(01/02/2012) A possibly ground-breaking idea has been kept on life support after Ecuador revealed its Yasuni-ITT Initiative had raked in $116 million before the end of the year, breaking the $100 million mark that Ecuador said it needed to keep the program alive. Ecuador is proposing to not drill for an estimated 850 million barrels of oil in the Ishpingo-Tambococha-Tiputinin (ITT) blocs of Yasuni National Park if the international community pledges $3.6 billion to a United Nations Development Fund (UNDF), or about half of what the oil is currently worth. The Yasuni-ITT Initiative would preserve arguably the most biodiverse region on Earth from oil exploitation, safeguard indigenous populations, and keep an estimated 410 million tons of CO2 out of the atmosphere. However, the initiative is not without its detractors, some arguing the program is little more than blackmail; meanwhile proponents say it could prove an effective way to combat climate change, deforestation, and mass extinction.
Peru's Cocha Cashu biological station changes management
(12/08/2011) The San Diego Zoo Global Wildlife Conservancy is taking over management of the productive Cocha Cashu field station in Manu National Park, Peru. To date, nearly 600 scientific papers have come out of research conducted at the station, making it among the five most productive research stations in the Amazon and Andes. Located in a part of the Amazon rainforest that has seen little human impact, the station was founded in 1969, four years before Manu National Park was gazetted.
Yasuni ITT: the virtues and vices of environmental innovation
(12/07/2011) As the 17th Conference of the Parties to the United Nations Framework Convention on Climate Change (UNFCCC) is taking place in Durban, Ecuador has embarked on the development of a project presented as highly innovative. This project targets Yasuni National Park, which has been protected since 1979. Yasuni is home to several indigenous peoples and is a biodiversity hotspot. But it so happens that the park also sits atop a vast oil field of 846 million barrels, representing about 20 percent of the country’s oil reserves. The acronym Yasuni ITT stands for Ishpingo-Tambococha-Tiputinin, which are the names of three potential zones for oil extraction.
New map reveals the most biodiverse place on Earth, but already threatened by oil
(09/22/2011) A new map highlights the importance of conserving Yasuni National Park as the most biodiverse ecosystem in the Western Hemisphere, and maybe even on Earth. Scientists released the map to coincide with the United National General Assembly in support of a first-of-its-kind initiative to save the park from oil exploration through international donations to offset revenue loss. Known as the Yasuni-ITT Initiative, the plan, if successful, would protect a 200,000 hectare bloc in Yasuni National Park from oil drilling in return for a trust fund of over $3 billion.
Photo: new titi monkey discovered in Amazon area under siege
(08/25/2011) A new species of titi monkey has been discovered in the Brazilian Amazon. Found during a 2010 December expedition, this is the second new titi monkey discovered in the Amazon in three years. In 2008 another new titi, dubbed the Caquetá titi, was discovered in the Colombian Amazon, although it was only announced last year. An expedition backed by WWF-Brazil found the new titi between the Guariba River and the Roosevelt River in northwestern part of Mato Grosso, a state of Brazil known as a center of Amazon destruction.
Cameratraps take global snapshot of declining tropical mammals
(08/17/2011) A groundbreaking cameratrap study has mapped the abundance, or lack thereof, of tropical mammal populations across seven countries in some of the world's most important rainforests. Undertaken by The Tropical Ecology Assessment and Monitoring Network (TEAM), the study found that habitat loss was having a critical impact on mammals. The study, which documented 105 mammals (nearly 2 percent of the world's known mammals) on three continents, also confirmed that mammals fared far better—both in diversity and abundance—in areas with continuous forest versus areas that had been degraded.
Animal picture of the day: the brilliant cock-of-the-rock
(08/16/2011) The Andean cock-of-the-rock (Rupicola peruvianus) is an unmistakable bird, whose males support such brilliant and bushy head plumage that their beaks are often hidden entirely, giving them a look wholly unique in the animal kingdom.
Lessons from the world's longest study of rainforest fragments
(08/15/2011) For over 30 years, hundreds of scientists have scoured eleven forest fragments in the Amazon seeking answers to big questions: how do forest fragments' species and microclimate differ from their intact relatives? Will rainforest fragments provide a safe haven for imperiled species or are they last stand for the living dead? Should conservation focus on saving forest fragments or is it more important to focus the fight on big tropical landscapes? Are forest fragments capable of regrowth and expansion? Can a forest—once cut-off—heal itself? Such questions are increasingly important as forest fragments—patches of forest that are separated from larger forest landscapes due to expanding agriculture, pasture, or fire—increase worldwide along with the human footprint.
Last chance to see: the Amazon's Xingu River
(06/15/2011) Not far from where the great Amazon River drains into the Atlantic, it splits off into a wide tributary, at first a fat vertical lake that, when viewed from satellite, eventually slims down to a wild scrawl through the dark green of the Amazon. In all, this tributary races almost completely southward through the Brazilian Amazon for 1,230 miles (1,979 kilometers)—nearly as long as the Colorado River—until it peters out in the savannah of Mato Grosso. Called home by diverse indigenous tribes and unique species, this is the Xingu River.
Germany backs out of Yasuni deal
(06/13/2011) Germany has backed out of a pledge to commit $50 million a year to Ecuador's Yasuni ITT Initiative, reports Science Insider. The move by Germany potentially upsets an innovative program hailed by environmentalists and scientists alike. This one-of-a-kind initiative would protect a 200,000 hectare bloc in Yasuni National Park from oil drilling in return for a trust fund of $3.6 billion, or about half the market value of the nearly billion barrels of oil lying underneath the area. The plan is meant to mitigate climate change, protect biodiversity, and safeguard the rights of indigenous people.
Uncovering the private lives of Amazon wildlife through camera traps
(05/20/2011) One of the best words to describe Amazon wildlife, including large mammals and birds, is cryptic. A person can spend a day trekking through the dense green and brown foliage of the Amazon and see nothing more than a few insects, maybe a frog here and there if they have good eyes. In fact, researchers have spent years in the jungle and never seen a jaguar, let alone a tapir. Some species like the bushdog and the giant armadillo are even more cryptic. Almost never encountered by people, in some parts of the Amazon they have taken on a mythic status, more rumor around the fire than reality. However, camera traps—automated cameras that take a flash photo whenever an animal triggers an infrared sensor—in the Amazon have begun to reveal long-sought information about the presence and abundance of species, providing new data on range and territories. And even at times giving glimpses into the private lives of species that remain largely shrouded in mystery.
'Luck and perseverance': new plant genus discovered in Amazon
(03/31/2011) The discovery of a new plant species is not uncommon, especially in places of remarkable biodiversity such as the Amazon rainforest. However, discovering a new plant genus, a taxonomic rank above species, is, according to Henk van der Werff fromt the Missouri Botanical Garden (MBG), "a matter of luck and perseverance". Researchers with the Missouri Botanical Garden have been blessed with both as they have announced two new species of Amazonian plants, one from Ecuador and one from Peru, that comprise a completely new genus: named, Yasunia, since the plant was originally discovered in Ecuador's vast Yasuni National Park.
Amazon still neglected by researchers
(03/28/2011) Although the Amazon is the world's largest tropical forest, it is not the most well known. Given the difficulty of access along with the fear of disease, dangerous species, indigenous groups, among other perceived perils, this great treasure chest of biology and ecology was practically ignored by scientists for centuries. Over the past few decades that trend has changed, however even today the Amazon remains lesser known than the much smaller, and more secure, tropical forests of Central America. A new study in mongabay.com's open access journal Tropical Conservation Science, which surveyed two prominent international tropical ecology journals (Biotropica and Journal of Tropical Ecology) between 1995 and 2008, finds that Central America was the subject of twice as many studies as the Amazon. In fact, according to the authors, much of the Amazon remains terra incognito to researchers, even as every year more of the rainforest is lost to human impacts.
Photos: two new freshwater stingrays discovered in the Amazon
(03/09/2011) Few people probably realize that in the rivers and lakes of the Amazon rainforest large stingrays glide, searching for crustaceans and small fish. Equipped with a powerful barbed tail they are often feared by locals. However, even as big as these fish are, new species continue to be described. Recently, scientists have identified two new species of Amazonian freshwater stingray near Iquitos, Peru. The new stingrays are unique enough to be placed in a new genus (the taxonomic level above species) called Heliotrygon, the first new Amazonian stingray genus to be described in nearly 25 years.
Not enough data on world's tropical plants to predict impact of warming world
(02/14/2011) How many tropical plant species are threatened by climate change? Which plants have big enough ranges to survive a warming world, not to mention deforestation? How likely is it that the tropics are undergoing a current mass extinction? These questions may appear straight forward, but a new study in Global Change Biology finds that researchers lack the hard data necessary to come to any confident conclusions. According to the study, nine out of ten tropical plants from Africa, Asia, and South America lack the minimum number of collections needed (at least 20) to determine the species' range, and therefore predict the impact of climate change.
Vines rising in the Amazon and other American rainforests
(02/14/2011) For years tropical scientists have anecdotally reported an increase in vines in the Amazon and other American tropical forests, but now a number of studies have confirmed such reports: vines are on the rise in Neotropical rainforests.
Paradise & Paradox: a semester in Ecuador
(02/02/2011) A semester abroad is an opportunity to live a sort of compacted life. In a few short months you seem to gain the experience of a much longer time and make enough memories to fill years. I recall a weeklong trip to the Alvord Desert with a field biology class from Portland Community College: the adventure of living out of a van, conducting research, and experiencing a place with classmates turned colleagues and professors turned friends who knew the desert like the backs of their hands. In that regard, it had a lot in common with my semester in Ecuador, but I can't think of anything that could have prepared me for a four month stay in a small South American country that I knew very little about.
Oil, indigenous people, and Ecuador's big idea
(11/23/2010) Ecuador's big idea—potentially Earth-rattling—goes something like this: the international community pays the small South American nation not to drill for nearly a billion barrels of oil in a massive block of Yasuni National Park. While Ecuador receives hundred of millions in an UN-backed fund, what does the international community receive? Arguably the world's most biodiverse rainforest is saved from oil extraction, two indigenous tribes' requests to be left uncontacted are respected, and some 400 million metric tons of CO2 is not emitted from burning the oil. In other words, the international community is being asked to put money where its mouth is on climate change, indigenous rights, and biodiversity loss. David Romo Vallejo, professor at the University of San Francisco Quito and co-director of Tiputini research station in Yasuni, recently told mongabay.com in an interview that this is "the best proposal so far made to ensure the protection of this incredible site."
Amazon biodiversity older than believed
(11/11/2010) A new study in Science has found that the incredible biodiversity of the Amazon rainforest goes back much further than expected, perhaps upending old ideas about how the Amazon basin became arguably the world's most biodiverse ecosystem. According to the study, the origin of rich biodiversity in the Amazon likely goes back more than 20 million years when the Andean mountains were rising.
Rainforests thrived in warmer conditions in the past, yet study requires "caution"
(11/11/2010) A new study in Science is likely to reopen the contentious debate about the impact of climate change on tropical rainforests. Scientific modeling of future climate conditions in tropical rainforests, such as the Amazon, has shown that climate change—combined with deforestation and fire—could create a tipping point whereby a significant portion of the Amazon could turnover to savannah, pushing untold species to extinction and undercutting the many ecosystem services provided by tropical rainforests. Yet, a new study headed by Carlos Jaramillo, staff scientist at the Smithsonian Tropical Research Institute (STRI), has found a tropical forest ecosystem thriving in much warmer conditions than today.
Eight new plants discovered in Bolivia
(11/07/2010) Researchers have described eight new species of plant from in and near Madidi National Park in the Bolivian Andes. Described in the journal Novon by botanists with the Missouri Botanical Garden and the National Herbaium in Laz Paz, Bolivia, seven of the eight plants were found as apart of the Proyecto Madidi (Project Madidi), a ten year effort to describe the plant species of three inter-connecting protected areas in Bolivia—Madidi National Park, Pilón Lajas Biosphere Reserve and Communal Lands, and Apolobamba Integrated Management Natural Area.
Undergrads in the Amazon: American students witness beauty and crisis in Yasuni National Park, Ecuador
(10/28/2010) Although most Americans have likely seen photos and videos of the world's largest rainforest, the Amazon, they will probably never see it face-to-face. For many, the Amazon seems incredibly remote: it is a dim, mysterious place, a jungle surfeit in adventure and beauty—but not a place to take a family vacation or spend a honeymoon. This means that the destruction of the Amazon, like the rainforest itself, also appears distant when seen from Oregon or North Carolina or Pennsylvania. Oil spills in Ecuador, cattle ranching in Brazil, hydroelectric dams in Peru: these issues are low, if not non-existent, for most Americans. But a visit to the Amazon changes all that. This was recently confirmed to me when I traveled with American college students during a trip to far-flung Yasuni National Park in Ecuador. As a part of a study abroad program with the University of San Francisco in Quito and the Galapagos Academic Institute for the Arts and Sciences (GAIAS), these students spend a semester studying ecology and environmental issues in Ecuador, including a first-time visit to the Amazon rainforest at Tiputini Biodiversity Station in Yasuni—and our trips just happened to overlap.
Life shocker: new species discovered every three days in the Amazon
(10/26/2010) A new report by the World Wide Fund for Nature (WWF) confirms the Amazon rainforest, even as it is shrinking due to deforestation, remains among the world's most surprising places. According to the report, Amazon Alive, over the past decade (1999-2009) researchers have found 1,200 new species in the Amazon: one new species for every three days. Not surprisingly invertebrates, including insects, made up the bulk of new discoveries. But no type of species was left out: from 1999-2009 researchers discovered 637 new plants, 357 fish, 216 amphibians, 55 reptiles, 39 mammals, and 16 new birds. In new discoveries over the past decade, the Amazon has beaten out a number of high-biodiversity contenders including Borneo, the Eastern Himalayas, and the Congo rainforest.
Can 'boutique capitalism' help protect the Amazon?
(10/11/2010) Most companies talk green, but few—almost none in fact—actually walk the walk. Sustainable design company, Ecostasy, not only walks the walk, but actually seeks out among the most challenging places to work: the imperiled Brazilian Amazon. Specializing in hand-crafted products by indigenous groups—such as jewelry, pots, and furniture—Ecostasy seeks to balance smart economics, environmental protection, and community development. Make no mistake, however, Ecostasy is not a non-profit, but a rare and refreshing example of a company truly dedicated to changing the world for the better. "In my mind, a virtuous company does not compromise ethical principles for economic interests. For me, being ethical is comprised of conducting oneself with honesty and responsibility to one’s constituencies (customers, employees, suppliers), society and the environment," Katherine Ponte, founder of Ecostasy, told mongabay.com in an interview.
Yasuni on film: could a documentary save the world's most biodiverse ecosystem?
(10/04/2010) How do you save one of the most biologically and culturally diverse places in the world if most people have never heard of it? If you want a big audience—you make a film. This is what wildlife-filmmaker Ryan Killackey is hoping to do with his new movie Yasuni Man. Killackey says the film will show-off the wonders of Yasuni National Park while highlighting the complexity of its biggest threat: the oil industry. "Conceptually, the film resembles a true-life cross between the documentary Crude and the blockbuster Avatar—except it's real and it's happening now," Killackey told mongabay.com.
How the overlooked peccary engineers the Amazon, an interview with Harald Beck
(09/20/2010) When people think of the Amazon rainforest, they likely think of roaring jaguars, jumping monkeys, marching ants, and squeezing anacondas. The humble peccary would hardly be among the first animals to cross their mind, if they even know such pig-like animals exists! Yet new research on the peccary is proving just how vital these species are to the world's greatest rainforest. As seed dispersers and seed destroyers, engineers of freshwater habitats and forest gaps, peccaries play an immense, long overlooked, role in the rainforest. "Peccaries have the highest density and biomass of any Neotropical mammal species. Obviously these fellows have quite an appetite for almost anything, but primarily they consume fruits and seeds. Their specialized jaws allow them to crush very hard seeds. The cracking sounds can be heard through the thick vegetation long before we could see them. As peccary herds bulldoze through the leaf litter in search for insects, frogs, seeds, and fruits, they destroy (i.e. snap and trample) many seedlings and saplings, sometimes leaving only the bare ground behind," Harald Beck, assistant professor at Towson University in Maryland, told mongabay.com in an interview.
Stunning monkey discovered in the Colombian Amazon
(08/11/2010) While the Amazon is being whittled away on all sides by logging, agriculture, roads, cattle ranching, mining, oil and gas exploration, today's announcement of a new monkey species proves that the world's greatest tropical rainforest still has many surprises to reveal. Scientists with the National University of Colombia and support from Conservation International (CI) have announced the discovery of a new monkey in the journal Primate Conservation on the Colombian border with Peru and Ecuador. The new species is a titi monkey, dubbed the Caquetá titi ( Callicebus caquetensis). However, the announcement comes with deep concern as researchers say it is likely the new species is already Critically Endangered due to a small population living in an area undergoing rapid deforestation for agriculture.
Hunting threatens the other Amazon: where harpy eagles are common and jaguars easy to spot, an interview with Paul Rosolie
(08/05/2010) If you have been fortunate enough to visit the Amazon or any other great rainforest, you've probably been wowed by the multitude and diversity of life. However, you also likely quickly realized that the deep jungle is not quite what you may have imagined when you were a child: you don't watch as jaguars wrestle with giant anteaters or anacondas circle prey. Instead life in the Amazon is small: insects, birds, frogs. Even biologists will tell you that you can spend years in the Amazon and never see a single jaguar. Yet rainforest guide and modern day explorer Paul Rosolie says there is another Amazon, one so pristine and with such wild abundance that it seems impossible to imagine if not for Rosolie's stories, photos, and soon videos. This is an Amazon where the big animals—jaguars, tapir, anaconda, giant anteaters, and harpy eagles—are not only abundant but visible. Free from human impact and overhunting, these remote places—off the beaten path of tourists—are growing ever smaller and, according to Rosolie, are in danger of disappearing forever.
New bird discovered in Colombia—and released alive
(05/26/2010) Researchers have discovered a new species of antpitta in the montane cloud forests of the Colibri del Sol Bird Reserve in western Colombia. A thrush-like bird, the new cinnamon and gray species was, according to a press release by the American Bird Conservancy (ABC), "captured, banded, measured, photographed, sampled for DNA, and then released alive back into the wild". This is one of only a few incidences in which a new species has been described without 'collecting' an individual (i.e. killing) to provide a model of the species in a museum. The new bird has been named Fenwick's antpitta (Grallaria fenwickorum) after the President of ABC, George Fenwick, and his family.
More of the Amazon opened to oil development
(05/24/2010) Perupetro, the Peruvian government's oil and gas corporate leasing body, announced last week that it will open an additional 25 lots for oil and gas exploration in the Amazon covering an area of 10 million hectares (nearly 25 million acres). Peru's national Amazon indigenous group, AIDESEP, criticized the move calling it a 'new threat' to Peru's indigenous group. According to Amazon Watch these new lots mean that 75 percent of the Peruvian Amazon is now open to oil and gas exploration and drilling.
Long-distance seed dispersal and hunting, an interview with Kimberly Holbrook
(05/24/2010) Scientists are just beginning to uncover the complex relationship between healthy biodiverse tropical forests and seed dispersers—species that spread seeds from a parent tree to other parts of the forest including birds, rodents, primates, and even elephants. By its very nature this relationship consists of an incredibly high number of variables: how abundant are seed dispersers, which animals spread seeds the furthest, what species spread which seeds, how are human impacts like hunting and deforestation impacting successful dispersal, as well as many others. Dr. Kimberly Holbrook has begun to answer some of these questions.
Collapsing biodiversity is a 'wake-up call for humanity'
(05/10/2010) A joint report released today by the Convention on Biological Diversity (CBD) and the UN Environment Program (UNEP) finds that our natural support systems are on the verge of collapsing unless radical changes are made to preserve the world's biodiversity. Executive Secretary of the Convention on Biological Diversity, Ahmed Djoghlaf, called the bleak report "a wake-up call for humanity."
Oil company to cut 454 kilometers of seismic lines in uncontacted tribe territory
(04/21/2010) Repsol YPF, a Spanish-Argentine oil company, plans to cut 454 kilometers (282 miles) of seismic lines in a territory of the Peruvian rainforest known to be home to uncontacted indigenous peoples, according to a press release from Survival International. To construct seismic lines paths will be cleared in the forest and explosives set-off regularly. Seismic lines allow energy companies to locate oil deposits by creating a cross sectional view of the subsurface.
More research and conservation efforts needed to save Colombia's monkeys
(03/29/2010) Approximately thirty monkey species inhabit the tropical forests of Colombia with at least five found no-where else in the world. A new review appearing the open access journal Tropical Conservation Science of Colombia's primates finds that a number of these species, including some greatly endangered species, have been neglected by scientists. The researchers looked at over 3,500 studies covering over a century of research by primatologists.
Secrets of the Amazon: giant anacondas and floating forests, an interview with Paul Rosolie
(03/10/2010) At twenty-two Paul Rosolie has seen more adventure than many of us will in our lifetime. First visiting the Amazon at eighteen, Rosolie has explored strange jungle ecosystems, caught anaconda and black caiman bare-handed, joined indigenous hunting expeditions, led volunteer expeditions, and hand-raised a baby giant anteater. "Rainforests were my childhood obsession," Rosolie told Mongabay.com. "For as long as I can remember, going to the Amazon had been my dream […] In those first ten minutes [of visiting], cowering under the bellowing calls of howler monkeys, I saw trails of leaf cutter ants under impossibly large, vine-tangled trees; a flock of scarlet macaws crossed the sky like a brilliant flying rainbow. I saw a place where nature was in its full; it is the most amazing place on earth."
Why seed dispersers matter, an interview with Pierre-Michel Forget, chair of the FSD International Symposium
(03/07/2010) There are few areas of research in tropical biology more exciting and more important than seed dispersal. Seed dispersal—the process by which seeds are spread from parent trees to new sprouting ground—underpins the ecology of forests worldwide. In temperate forests, seeds are often spread by wind and water, though sometimes by animals such as squirrels and birds. But in the tropics the emphasis is far heavier on the latter, as Dr. Pierre-Michel Forget explains to mongabay.com. "[In rainforests] a majority of plants, trees, lianas, epiphytes, and herbs, are dispersed by fruit-eating animals. […] As seed size varies from tiny seeds less than one millimetres to several centimetres in length or diameter, then, a variety of animals is required to disperse such a continuum and variety of seed size, the smaller being transported by ants and dung beetles, the larger swallowed by cassowary, tapir and elephant, for instance."
Guyana bans gold mining in the 'Land of the Giants'
(03/01/2010) Guyana has banned gold dredging in the Rewa Head region of the South American country after pressure from Amerindian communities in the area. A recent expedition to Rewa Head turned up unspoiled wilderness and mind-boggling biodiversity. The researchers, in just six weeks, stumbled on the world's largest snake (anaconda), spider (the aptly named goliath bird-eating spider), armadillo (the giant armadillo), anteater (the giant anteater), and otter (the giant otter), leading them to dub the area 'the Land of the Giants'. "During our brief survey we had encounters with wildlife that tropical biologists can spend years in the field waiting for. On a single day we had two tapirs paddle alongside our boat, we were swooped on by a crested eagle and then later charged by a group of giant otters."
Under siege: oil and gas concessions cover 41 percent of the Peruvian Amazon
(02/16/2010) A new study in the Environmental Research Letter finds that the Peruvian Amazon is being overrun by the oil and gas industries. According to the study 41 percent of the Peruvian Amazon is currently covered by 52 separate oil and gas concessions, nearly six times as much land as was covered in 2003. "We found that more of the Peruvian Amazon has recently been leased to oil and gas companies than at any other time on record," explained co-author Dr. Matt Finer of the Washington DC-based Save America’s Forests in a press release. The concessions even surpass the oil boom in the region during the 1970s and 80s, which resulted in extensive environmental damage.
Birder captures first footage ever of long whiskered owlet, one of the world's rarest birds
(02/04/2010) It was any birders dream come true: not only to see one of the world's rarest birds, but to discover a new unknown population. Israeli birder, Shachar Alterman, was surveying birds with the UK organization Neotropical Primate Conservation in Peruvian cloud forest when he heard and then saw the long whiskered owlet.
Photos: park in Ecuador likely contains world’s highest biodiversity, but threatened by oil
(01/19/2010) In the midst of a seesaw political battle to save Yasuni National Park from oil developers, scientists have announced that this park in Ecuador houses more species than anywhere else in South America—and maybe the world. "Yasuní is at the center of a small zone where South America's amphibians, birds, mammals, and vascular plants all reach maximum diversity," Dr. Clinton Jenkins of the University of Maryland said in a press release. "We dubbed this area the 'quadruple richness center.'"
Guyana expedition finds biodiversity trove in area slated for oil and gas development, an interview with Robert Pickles
(11/29/2009) An expedition deep into Guyana's rainforest interior to find the endangered giant river otter—and collect their scat for genetic analysis—uncovered much more than even this endangered charismatic species. "Visiting the Rewa Head felt like we were walking in the footsteps of Wallace and Bates, seeing South America with its natural density of wild animals as it would have appeared 150 years ago," expedition member Robert Pickles said to Mongabay.com.
Deforestation emissions should be shared between producer and consumer, argues study
(11/19/2009) Under the Kyoto Protocol the nation that produces carbon emission takes responsibility for them, but what about when the country is producing carbon-intensive goods for consumer demand beyond its borders? For example while China is now the world's highest carbon emitter, 50 percent of its growth over the last year was due to producing goods for wealthy countries like the EU and the United States which have, in a sense, outsourced their manufacturing emissions to China. A new study in Environmental Research Letters presents a possible model for making certain that both producer and consumer share responsibility for emissions in an area so far neglected by studies of this kind: deforestation and land-use change.
Crisis averted for now, Peruvian natives will meet with Hunt Oil
(10/28/2009) Indigenous groups in a dispute with Hunt Oil, over the company performing seismic tests their land, have scheduled a meeting with the Texas based oil corporation, according to Reuters.
Will Ecuador's plan to raise money for not drilling oil in the Amazon succeed?
(10/27/2009) Ecuador's Yasuni National Park is full of wealth: it is one of the richest places on earth in terms of biodiversity; it is home to the indigenous Waorani people, as well as several uncontacted tribes; and the park's forest and soil provides a massive carbon sink. However, Yasuni National Park also sits on wealth of a different kind: one billion barrels of oil remain locked under the pristine rainforest.
Amazonian natives say they will defend tribal lands from Hunt Oil with "their lives"
(10/25/2009) Indigenous natives in the Amazon are headed to the town of Salvacion in Peru with a plan to forcibly remove the Texas-based Hunt Oil company from their land as early as today. Peruvian police forces, numbering in the hundreds, are said to be waiting in the town. The crisis has risen over an area known as Lot 76, or the Amarakaeri Communal Reserve. The 400,000 hectare reserve was created in 2002 to protect the flora and fauna of the area, as well as to safeguard watersheds of particular importance to indigenous groups in the region.
The faster, fiercer, and always surprising sloth, an interview with Bryson Voirin
(10/25/2009) Sloths sleep all day; they are always slow; and they are gentle animals. These are just some of the popular misconceptions that sloth-scientist and expert tree-climber, Bryson Voirin, is overturning. After growing up among the wild creatures of Florida, spending his high school years in Germany, and earning a Bachelors degree in biology and environment at the New College of Florida, Voirin found his calling. At the New College of Florida, Voirin "met Meg Lowman, the famous canopy pioneer who invented many of the tree climbing techniques everyone uses today."
Will tropical trees survive climate change?, an interview with Kenneth J. Feeley
(09/24/2009) One of the most pressing issues in the conservation today is how climate change will affect tropical ecosystems. The short answer is: we don't know. Because of this, more and more scientists are looking at the probable impacts of a warmer world on the Earth's most vibrant and biodiverse ecosystems. Kenneth J. Feeley, tropical ecologist and new professor at Florida International University and the Center for Tropical Plant Conservation at the Fairchild Tropical Botanic Garden, is conducting groundbreaking research in the tropical forests of Peru on the migration of tree species due to climate change.
Working to save the 'living dead' in the Atlantic Forest, an interview with Antonio Rossano Mendes Pontes
(09/23/2009) The Atlantic Forest may very well be the most imperiled tropical ecosystem in the world: it is estimated that seven percent (or less) of the original forest remains. Lining the coast of Brazil, what is left of the forest is largely patches and fragments that are hemmed in by metropolises and monocultures. Yet, some areas are worse than others, such as the Pernambuco Endemism Centre, a region in the northeast that has largely been ignored by scientists and conservation efforts. Here, 98 percent of the forest is gone, and 70 percent of what remains are patches measuring less than 10 hectares. Due to this fragmentation all large mammals have gone regionally extinct and the small mammals are described by Antonio Rossano Mendes Pontes, a professor and researcher at the Federal University of Pernambuco, as the 'living dead'.
Oil road transforms indigenous nomadic hunters into commercial poachers in the Ecuadorian Amazon
(09/13/2009) The documentary Crude opened this weekend in New York, while the film shows the direct impact of the oil industry on indigenous groups a new study proves that the presence of oil companies can have subtler, but still major impacts, on indigenous groups and the ecosystems in which they live. In Ecuador's Yasuni National Park—comprising 982,000 hectares of what the researchers call "one of the most species diverse forests in the world"—the presence of an oil company has disrupted the lives of the Waorani and the Kichwa peoples, and the rich abundance of wildlife living within the forest.
Tiny monkey species discovered in the Amazon rainforest
(07/07/2009) A new species of monkey has been discovered in the Brazilian Amazon, reports the Wildlife Conservation Society. The monkey, a type of saddleback tamarin, has been named Mura's saddleback tamarin (Saguinus fuscicollis mura) after the Mura Indians, the Amerindian ethnic group that lives in the Purus and Madeira river basins where the monkey occurs.
Amazon could lose 60% of forest without triggering catastrophic die-off, claims new study
(06/16/2009) Brazil's setting aside of more than 500,000 square miles (1.25 million square kilometers) of rainforest in protected areas over the past decade may effectively buffer the Amazon from the effects of climate change, preventing Earth's largest rainforest from tipping towards arid savanna in the face of ongoing deforestation and rising temperatures, argues a new paper published in Proceedings of the National Academy of Sciences.
Photos: treasure trove of new species discovered in Ecuador
(06/16/2009) Near the once-contentious border of Ecuador and Peru in the mountainous forests of the Cordillera del Condor, scientists from Conservation International (CI) conducted a Rapid Assessment Program (RAP), uncovering what they believe are several new species, including four amphibians, one lizard, and seven insects. The team focused on the Upper Nanharitza River Basin, which has been geologically isolated from the rest of the Andes, giving it broad potential for new species.
Smallest Andean frog discovered in cloud forests of Peru
(03/18/2009) At 3,000 meters (9,842 feet) in the Andes herpetologists were surprised to discover a frog so small it could sit on a dime with room to spare. Further study showed that this new species, named Noble's pygmy frog, is the smallest frog in the Andean mountain range.
Poison frog diversity linked to the Andes
(03/10/2009) Electric colors, wild markings, and toxic skin have made poison frogs well-known inhabitants of the Amazon rainforest. With 353 recognized species, and probably more awaiting discovery, poison frogs are an incredibly diverse group of amphibians. While it has long been believed that the Amazon basin, itself, was the source of their diversity, a new study published in PLoS Biology has uncovered that the Andes mountain chain has served as an oven of evolutionary biodiversity for poison frogs over several million years.
Frogs can be used to predict biodiversity hotspots
(02/05/2009) Tree frogs may help scientists inexpensively predict biodiversity hotspots for conservation, report researchers writing in the journal Science.
How to make forest fragments more hospitable to wildlife
(01/27/2009) While deforestation garners more attention from environmentalists, fragmentation of forest habitats is of significant concern to ecologists. As forest is fragmented into islands by logging, roads, agriculture, and other disturbances, edge effects alter the structure, microclimate and species composition of the forest patches, usually reducing the overall number of species. Forest specialists are most likely to suffer, losing out to "weedier" generalists and species that can tolerate forest "edge" conditions. A new study, conducted in the Brazilian Amazon, takes a detailed look at the types of birds that are likely to persist, and even thrive, in forest fragments.
Brazil triples endangered species list
(11/05/2008) Brazil has nearly tripled the number of species on its endangered list due to development, overfishing, pollution, wildlife trafficking and deforestation, reports the Associated Press.
Rainforest biodiversity results from habitat specialization rather than chance
(10/22/2008) The rich diversity of trees in tropical forests may be "the result of subtle strategies that allow each species to occupy its own ecological niche" rather than random dispersal, report researchers writing in the journal Science.
Scientists discover 120 million year-old ant in the Amazon rainforest
(09/17/2008) Scientists have discovered a previously unknown species of ant in the Amazon that may shed light on the evolution of ants. The species is believed to be the oldest-known ant at around 120 million years old. The discovery is presented this week in the journal Proceedings of the National Academy of Sciences.
New tree species discovered in Amazon biodiversity hotspot
(08/17/2008) I was walking down the Anaconda Trail at the Madre Selva Biological Station with botanist Rodolfo Vasquez when he suddenly stopped, stared at the bark of a 120-foot tree, and started searching the ground. Odd behavior? Perhaps, but when you're with Peru's top field botanist, odd behavior is forgivable, since it means that something interesting is probably afoot.
Markets could save rainforests: an interview with Andrew Mitchell
(08/17/2008) Markets may soon value rainforests as living entities rather than for just the commodities produced when they are cut down, said a tropical forest researcher speaking in June at a conservation biology conference in the South American country of Suriname. Andrew Mitchell, founder and director of the London-based Global Canopy Program (GCP), said he is encouraged by signs that investors are beginning to look at the value of services afforded by healthy forests.
20% of the Brazilian Amazon's tree species to go extinct
(08/11/2008) A new study estimates the number of trees that will go extinct in the Brazilian Amazon due to habitat loss.
