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.


Leaf-cutter ants test theories about the Amazon's biodiversity

(07/23/2008) No one knows for certain how many insect species reside in the Amazon. One oft-quoted estimate is 30 million, but the actual number could be significantly lower or higher than this. Either way, biologists have long wondered why the richness of insect diversity in the Americas' tropical forests is exponentially higher than temperate forests. Three popular hypotheses have emerged—the theory of refugia, the marine incursion hypothesis, and the riverine barrier hypothesis. To test these theories a group of scientists, headed by Dr. Scott Solomon, studied three species of leaf-cutter ant species from the Amazon.


Fruit bats frequent clay-licks in the Amazon rainforest

(07/14/2008) In the Peru new research finds that female fruit bats are frequent visitors to clay-licks.

Amazon environmentalist gunned down in Peru

(03/14/2008) After reporting a truck loaded with mahogany illegally logged from the Amazon rainforest, Don Julio Garcia Agapito, a Peruvian environmentalist was gunned down by unknown assailants on February 26th, 2008. He is survived by his family.


Predator of the world's largest macaw key to its survival

(03/13/2008) In a bizarre biological twist, a new study shows that the Hyacinth Macaw depends on its greatest predator, the Toco Toucan, for continued survival.


Human impacts on primate conservation in central Amazonia

(03/03/2008) Deforestation in the Amazon is a serious concern. In the Brazilian Amazon, forests are cleared for cattle ranches, soybean cultivation, and selective logging practices. A new plan to settle approximately 180 families north of Manaus, the capital city of the state of Amazonas, has created widespread controversy. The land plots would be located within the study site of the longest-running study of forest fragmentation, the Biological Dynamics of Forest Fragments Project (BDFFP). Therefore, the plan would threaten scientific research at the BDFFP and other nearby research sites operated by the Instituto Nacional da Pesquisas de Amazônia (INPA) and Large Scale Biosphere-Atmosphere Experiment in Amazonia (LBA), as well as the future of the Central Amazonian conservation Corridor.


Small fires a big threat to Amazon rainforest biodiversity

Amazon state launches Zero Extinction Program for endangered species

(02/21/2008) The Brazilian state of Para has launched the Zero Extinction Program, an initiative to prevent threatened species from going extinct by protecting their habitats.


conservation strategies can mitigate the impact of global warming in the Amazon

(02/19/2008) Careful design of protected areas to safeguard key "refugia" and allow for migration can increase the resilience of Amazon biodiversity to climate change, report researchers writing in Philosophical Transactions of the Royal Society B.


Amazon riparian zones need to be expanded to protect wildlife finds study

(02/19/2008) Strips of forest mandated by Brazilian law along rivers and streams in the Amazon rainforest are too narrow to effectively safeguard biodiversity, reports new research published in the journal conservation Biology.


New uakari monkey discovered in the Amazon rainforest

(02/05/2008) A previously unknown species of uakari monkey was discovered in the Brazilian Amazon, reports National Geographic News. The primate was identified after it was killed by Yanomamo Indians near the Brazil-Venezuela border.


An interview with primate researcher Dr. Karen Strier: America's largest monkey recovering after brush with extinction

(01/10/2008) The Atlantic forest of Brazil boasts South America's largest primates, the Southern and Northern Muriqui. The muriqui are unique among all primates, because they are not territorial and do not display aggressive behvaior. The IUCN has classified the Southern Muriqui as endangered, while the Nothern Muriqui is critically endangered. Dr. Karen Strier has studied the Northern Muriqui in the field for twenty-five years. A professor of zoology and anthropology at the University of Madison Wisconsin, she is the author of Faces in the Forest: the Endangered Muriqui Monkeys of Brazil and a new textbook entitled Primate behvaioral Ecology.


Amazon conservation Team wins "Innovation in conservation Award" for path-breaking work with Amazon tribes

(12/11/2007) The Amazon conservation Team (ACT) was today awarded mongabay.com's inaugural "Innovation in conservation Award" for its path-breaking efforts to enable indigenous Amazonians to maintain ties to their history and cultural traditions while protecting their rainforest home from illegal loggers and miners.


A comprehensive look at the use of animals in Brazilian medicine

(12/10/2007) For millennia animals have been used in medicine as remedies. While this practice has all but disappeared in western countries, many cultures still employ traditional medicine that includes animal-derived remedies. Probably the most famous of these are the Chinese, who for example use seahorses for a variety of ailments and rhinoceros horn as an aphrodisiac. Lesser known and studied, though just as varied and rich is Brazil's long tradition of animal-remedies for all kinds of ailments. A recent study set out to document the wide-range of animals used in Brazilian traditional medicine and its possible consequences on animal populations, the environment, and Brazilian society.


Could the carbon market save the Amazon rainforest?

(11/29/2007) The global carbon market could play a key role in saving the Amazon from the effects of climate change and economic development, which could otherwise trigger dramatic ecological changes, reports a new paper published in Science. The authors argue that a well-articulated plan, financed by carbon markets, could prevent the worst outcomes for the Amazon forest while generating economic benefits for the region's inhabitants.


In the Amazon, primary forest biodiversity tops that of secondary forest, plantations

(11/12/2007) Plantations and secondary forests are no match for primary Amazon rainforest in terms of biodiversity, reports the largest ever assessment of the biodiversity conservation value in the tropics.


New peccary species discovered by embattled Amazon scientist

(11/04/2007) A new species of peccary has been discovered in the Amazon rainforest by a scientist recently charged with biopiracy by the Brazilian government.


Amphibian extinction may be worse than thought

(10/31/2007) Amphibian extinction rates may be higher than previously thought, according to new DNA analysis that found more than 60 unrecognized species in the Guiana Shield of South America.


Amazon plant diversity still a mystery

(10/21/2007) The Amazon is one of the few places on the earth that still evokes an accurate sense of mystery. While the Taiga, Antarctica, and Sahara may compare to the Amazon in wilderness size, none hold the same mystique of unknown species. It is believed that one third of the world's species inhabits this tropical rainforest. The only region comparable in mystery (though not in species) may be the world's oceans.


New flycatcher bird species discovered in Peru

(08/13/2007) Scientists have discovered a previously unknown species of bird in dense bamboo thickets in the Peruvian Amazon.


Forest disturbance reduces biodiversity in the Amazon rainforest

(07/02/2007) Two new studies in the Amazon rainforest show that plantation forests and second-growth forests have lower species counts for butterflies, reptiles, and amphibians than adjacent primary forest areas. The research has important implications for conservation of tropical biodiversity in a world where old-growth forest is increasingly replaced by secondary forests, industrial plantations, and agricultural landscapes.


Two 'dragon' species discovered in Brazil

(01/24/2007) Two previously unknown species of lizard that are said to resemble miniature ground-dwelling dragons have been found in the threatened cerrado region of Brazil. The species, Stenocercus squarrosus and Stenocercus quinarius are described in the current issue of the South American Journal of Herpetology.


Strange spiny rodent discovered in the Amazon

(01/24/2007) Scientists have discovered a previously unknown species of arboreal rodent in the cloud forests of Peru. The species, named Isothrix barbarabrownae, is described in the current issue of Mastozoologia, the principal mammalogy journal of South America.
