Human impacts on primate conservation in central Amazonia
(3/3/2008) 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.

(2/19/2008) 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.


Conservation strategies can mitigate the impact of global warming in the Amazon
(2/19/2008) 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.


New uakari monkey discovered in the Amazon rainforest
(2/5/2008) 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
(1/10/2008) 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 behavior. 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 Behavioral 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
(11/4/2007) 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
(8/13/2007) 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
(7/2/2007) 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
(1/24/2007) 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.

Strange spiny rodent discovered in the Amazon
(1/24/2007) 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.


Photos of newly discovered species in Brazil's Amazon rainforest
(9/27/2006) Brazil has announced the creation of a Amapa State Forest, a 5.7 million acre Amazon protected area larger than the state of New Jersey. According to Conservation International (CI), "the designation protects a crucial section of the Amapa Biodiversity Corridor of northern Brazil, which includes some of the most pristine remaining Amazon forest." The Amapa Biodiversity Corridor -- which includes a variety of ecosystems including tropical forests, mangrove swamps, savannah, and wetlands -- is home to more than 1,700 species of animals and plants, including 430 species of birds, 104 species of amphibians, 124 reptile species and 127 mammal species, including 62 bat species, according to biological surveys conducted by Conservation International (CI) and the Amapa State Institute for Research. At the core of the Amapa Biodiversity Corridor is Tumucumaque National Park, the world's largest tropical forest park.


Amazon rainforest biodiversity due to biology not climate change says study
(12/5/2005) The biodiversity of the Amazon rainforest results from biological factors, not climate change as widely thought, says new research published in the journal Proceedings of the Royal Society B. Scientists have long argued that the species richness of tropical forests could be due to climate change-induced fragmentation, known as the "forest refuge: theory, and other external factors that caused geographic isolation. Now, researchers from University College London say that biological influences play a greater role in driving species evolution.


Vampire Fish discovered in the Amazon
