News articles on Amazon biodiversity
Mongabay.com news articles on Amazon biodiversity in blog format. Updated regularly.
(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.
