(10/09/2014) Scientists have long known that forest fragments are not the same ecologically as intact forest landscapes. When forests are slashed into fragments, winds dry out the edges leading to dying trees and rising temperatures. Biodiversity often drops, while local extinctions rise and big animals vanish. Now, a new study finds another worrisome impact of forest fragmentation: carbon emissions.
Saving the Atlantic Forest would cost less than 'Titanic'
(08/28/2014) Want to save the world's most imperiled biodiversity hotspot? You just need a down payment of $198 million. While that may sound like a lot, it's actually less than it cost to make the film, Titanic. A new study published today in Science finds that paying private landowners to protect the Atlantic Forest would cost Brazil just 6.5 percent of what it currently spends ever year on agricultural subsidies.
Only 15 percent of world's biodiversity hotspots left intact
(07/14/2014) The world's 35 biodiversity hotspots—which harbor 75 percent of the planet's endangered land vertebrates—are in more trouble than expected, according to a sobering new analysis of remaining primary vegetation. In all less than 15 percent of natural intact vegetation is left in the these hotspots, which include well-known jewels such as Madagascar, the tropical Andes, and Sundaland.
Will yellow fever drive brown howler monkeys to extinction in Argentina?
(04/04/2014) The brown howler monkey is listed as Critically Endangered in Argentina, where a small number persist in the northeastern portion of the country. Although habitat loss and other human impacts have contributed to the populations’ decline, a new report indicates that yellow fever outbreaks in the region are primarily to blame.
Scientists: well-managed forest restoration benefits both biodiversity and people
(12/16/2013) In November this year, the world was greeted by the dismaying news that deforestation of the Brazilian Amazon jumped 28% in the past year. The year 2013 also holds the dubious distinction of being the first time since humans appeared on the planet, that carbon concentrations in the atmosphere rose to 400 parts per million. A map by Google revealed that Russia, Brazil, the United States, Canada and Indonesia all displayed over 10 million hectares of gross forest loss from 2000-2012, with the highest deforestation rate occurring in Malaysia.
Odd porcupine hugely imperiled by hunting, deforestation
(12/16/2013) The thin-spined porcupine, also known as the bristle-spined rat, is a truly distinct animal: a sort of cross between New World porcupines and spiny rats with genetic research showing it is slightly closer to the former rather than the latter. But the thin-spined porcupine (Chaetomys subspinosus), found only in Brazil's Atlantic Forest, is imperiled by human activities. In fact, a new study in mongabay.com's open access journal Tropical Conservation Science found that the species remains a target for hunters, despite a reputation for tasting terrible.
Scientists discover new cat species roaming Brazil
(11/27/2013) As a family, cats are some of the most well-studied animals on Earth, but that doesn't mean these adept carnivores don't continue to surprise us. Scientists have announced today the stunning discovery of a new species of cat, long-confused with another. Looking at the molecular data of small cats in Brazil, researchers found that the tigrina—also known as the oncilla in Central America—is actually two separate species. The new species has been dubbed Leopardus guttulus and is found in the Atlantic Forest of southern Brazil, while the other Leopardus tigrinus is found in the cerrado and Caatinga ecosystems in northeastern Brazil.
Forest fragmentation leading to higher extinction rates
(08/13/2013) The world's species are in worse trouble than widely-assumed, according to a new paper in the Proceedings of the National Academy of Sciences (PNAS), which reevaluates how scientists estimate extinction rates. The new model takes into account the impact of forest fragmentation on extinction rates for the first time, filling in a gap in past estimates. Much of the world's tropical forests, which house the bulk of the world's species, have been whittled down to fragments: small forest islands that no longer connect to larger habitat. According to the paper, species confined to fragments have a higher likelihood of vanishing.
Little NGO takes on goliath task: conserving the vanishing ecosystems of Paraguay
(08/12/2013) Landlocked in the navel of South America, the forests, wetlands and savannahs of Paraguay boast rich biodiversity and endemic species, yet the unique landscapes of Paraguay also face increasing threats, primarily from agricultural expansion. Controlled burns and clear cutting have become common practice as wildlands are converted for soy and cattle production. In some areas this land conversion is rapid: the Paraguayan Chaco, for instance, is being lost at a rate of 10% per year. One organization is working to reverse this trend. Para La Tierra (PLT) is a small NGO dedicated to the conservation of threatened habitats in Paraguay. Located on the Reserva Natural Laguna Blanca, in-between two of South America's most threatened habitats: the Atlantic Forest and the vast topical savannah known as the cerrado, PLT is in a unique position to champion conservation.
On guard: protecting wildlife in a heavily hunted Brazilian forest
(06/24/2013) The Brazilian government offers tax relief to landowners who set aside areas for preservation. While this has expanded the system of private ecological reserves considerably, the Brazilian government currently lacks funding to enforce the protection of these lands from threats such as hunting, leaving the responsibility to the landowners.
Loss of big fruit-eating birds impacting trees in endangered rainforests
(05/31/2013) The extinction of large, fruit-eating birds in fragments of Brazil's Atlantic rainforest has caused palm trees to produce smaller seeds over the past century, impacting forest ecology, finds a study published in the journal Science.
New insect discovered in Brazil, only third known in its bizarre family (photos)
(04/15/2013) A new species of forcepfly named Austromerope brasiliensis, was recently discovered in Brazil and described in the open access journal Zoo Keys. This is the first discovery of forcepfly in the Neotropics and only the third known worldwide. The forcepfly, often called the earwigfly because the male genital forceps closely resemble the cerci of the common earwig, remains a scientific enigma due to the lack of information on the family.
New species tree-dwelling porcupine discovered in critically threatened Brazilian habitat
(04/11/2013) Scientists in Brazil have described a new species of tree-dwelling porcupine in the country's most endangered ecosystems. The description is published in last week's issue of Zootaxa.
Nest of one of world's rarest birds discovered for the first time
(01/17/2013) A nest belonging to one of the world's rarest birds has been discovered by researchers for the first time in Brazil, reports the American Bird Conservancy.
Recovery of Atlantic Forest depends on land-use histories
(12/10/2012) The intensity of land-use influences the speed of regeneration in tropical rainforests, says new research. Tropical rainforests are a priority for biodiversity conservation; they are hotspots of endemism but also some of the most threatened global habitats. The Atlantic Forest stands out among tropical rainforests, hosting an estimated 8,000 species of endemic plants and more than 650 endemic vertebrates. However, only around 11 percent of these forests now remain.
Endangered muriqui monkeys in Brazil full of surprises
(11/26/2012) On paper, the northern muriquis (Brachyteles hypoxanthus) look like a conservation comeback story. Three decades ago, only 60 of the gentle, tree-dwelling primates lived in a fragment of the Atlantic Forest along the eastern coast of Brazil. Now there are more than 300. But numbers don’t tell the whole story, according to anthropologist Karen Strier and theoretical ecologist Anthony Ives of the University of Wisconsin, Madison. The pair analyzed 28 years of data on the demographics of the muriquis, one of the longest studies of its kind. They found surprising patterns about birth and death rates, sex ratios, and even how often the monkeys venture out of their trees. These findings raise questions about the muriquis’ long-term survival and how best to protect them, the scientists wrote in the Sept 17 issue of PLoS ONE.
Happy Halloween: nine new species of tree-climbing tarantula discovered
(10/31/2012) If you suffer from acute arachnophobia, this is the perfect Halloween discovery for you: a spider expert has discovered nine new species of arboreal (tree-dwelling) tarantulas in the Brazil. Although tarantula diversity is highest in the Amazon rainforest, the new species are all found in lesser-known Brazilian ecosystems like the Atlantic Forest, of which less than 7 percent remains, and the cerrado, a massive savannah that is being rapidly lost to agriculture and cattle ranching.
Key mammals dying off in rainforest fragments
(08/15/2012) When the Portuguese first arrived on the shores of what is now Brazil, a massive forest waited for them. Not the Amazon, but the Atlantic Forest, stretching for over 1.2 million kilometers. Here jaguars, the continent's apex predator, stalked peccaries, while tapirs waded in rivers and giant anteaters unearthed termites mounds. Here, also, the Tupi people numbered around a million people. Now, almost all of this gone: 93 percent of the Atlantic Forest has been converted to agriculture, pasture, and cities, the bulk of it lost since the 1940s. The Tupi people are largely vanished due to slavery and disease, and, according to a new study in the open access journal PLoS ONE, so are many of the forest's megafauna, from jaguars to giant anteaters.
Deforestation in Brazil's Mata Atlantica drops
(06/06/2012) Deforestation of Brazil's Mata Atlântica — a forest ecosystem more threatened than the Amazon rainforest — fell to 133 square kilometers between 2010 and 2011, down about 14.7 percent from the annual average between 2008 and 2010, reports Brazil's National Institute for Space Research (INPE) and Fundação SOS Mata Atlântica.
Tribe partners to protect Argentina's most endangered forest
(05/17/2012) Last month, three Guarani communities, the local Argentine government of Misiones, and the UK-based NGO World Land Trust forged an agreement to create a nature reserve connecting three protected areas in the fractured, and almost extinct, Atlantic Forest. Dubbed the Emerald Green Corridor, the reserve protects 3,764 hectares (9,301 acres) in Argentina; although relatively small, the land connects three protected other protected areas creating a combined conservation area (41,000 hectares) around the size of Barbados in the greater Yaboti Biosphere Reserve. In Argentina only 1 percent of the historical Atlantic Forest survives.
Invasive primates threaten Atlantic Forest natives
(03/19/2012) Scientists have called for the removal of eight invasive primates from Brazil's imperiled Atlantic Forest in a new study published in mongabay.com's open access journal Tropical Conservation Society. The researchers fear that the eight alien monkeys could hurt other species due to increased competition, predation, and possible disease.
Expanding ethanol threatens last remnants of Atlantic Forest
(09/26/2011) Aggressively expanding sugarcane ethanol is putting Brazil's nearly-vanished Atlantic Forest at risk, according to an opinion piece in mongabay.com's open-access journal Tropical Conservation Science. Already down to less than 12 percent of its original extent, the Atlantic Forest—home to over 7,000 species that survive no-where else—is facing a new peril from ethanol, used as an alternative to gasoline and often touted as 'green' or 'environmentally-sustainable'.
Atlantic Forest stores less carbon due to drastic fragmentation
(09/26/2011) The Atlantic Forest in Brazil is one of the most fragmented and damaged forests in the world. Currently around 12 percent of the forest survives, with much of it in small fragments, many less than 100 hectares. A new study in mongabay.com's open-access journal Tropical Conservation Science finds that the bloodied nature of the Atlantic Forest impacts its capacity to sequester carbon. The study found that 92 percent of the forest stored only half its potential carbon due to fragmentation and edge-effects, which includes damage due to winds and exposure to drought.
Loving the tapir: pioneering conservation for South America's biggest animal
(09/11/2011) Compared to some of South America's megafauna stand-out species—the jaguar, the anaconda, and the harpy eagle come to mind—the tapir doesn't get a lot of love. This is a shame. For one thing, they're the largest terrestrial animal on the South American continent: pound-for-pound they beat both the jaguar and the llama. For another they play a very significant role in their ecosystem: they disperse seeds, modify habitats, and are periodic prey to big predators. For another, modern tapirs are some of the last survivors of a megafauna family that roamed much of the northern hemisphere, including North America, and only declined during the Pleistocene extinction. Finally, for anyone fortunate enough to have witnessed the often-shy tapir in the wild, one knows there is something mystical and ancient about these admittedly strange-looking beasts.
Taking corporate sustainability seriously means changing business culture
(08/11/2011) As more and more people demand companies to become sustainable and environmentally conscious, many corporations are at a loss of how to begin making the changes necessary. If they attempt to make changes—but fall short or focus poorly—they risk their actions being labeled as 'greenwash'. In addition, if they implement smart changes and self-regulations, but their employees don't buy-in to the process, all their investments will be for nothing. This is where Accountability Now, a young, fresh social responsibility agency, comes in. Clare Raybould, director of Accountability Now, believes companies—large and small—have the potential to change the world for the better, but they simply need a guiding hand to change not just the way a company works, but its culture.
Destruction of Brazil's most endangered forest, the Mata Atlantica, slows
(05/27/2011) Deforestation of Brazil's most threatened forest ecosystem dropped substantially during the 2008-2010 period according to new data released by Brazil's National Institute for Space Research (INPE) and Fundação SOS Mata Atlântica. Analysis of satellite images across 16 of the 17 states the Atlantic Forest spans found that 312 square kilometers of forest was cleared between 2008 and 2010, down from 1,029 square kilometers between 2005 and 2008. Deforestation was concentrated in the states of Minas Gerais, Bahia, Santa Catarina and Parana.
Photos: the top ten new species discovered in 2010
(05/23/2011) If we had to characterize our understanding of life on Earth as either ignorant or knowledgeable, the former would be most correct. In 250 years of rigorous taxonomic work researchers have cataloged nearly two million species, however scientists estimate the total number of species on Earth is at least five million and perhaps up to a hundred million. This means every year thousands of new species are discovered by researchers, and from these thousands, the International Institute for Species Exploration at Arizona State University selects ten especially notable new species.
Critically endangered capuchins make tools to gather termites
(03/10/2011) Less than 200 blond capuchins (Cebus falvius) survive in the highly-fragmented habitat of Brazil's Atlantic Forest. But this tiny group of monkeys, only rediscovered in 2006, is surprising scientists with its adept tool-using abilities. Displaying similar behavior to that which made the chimpanzees of Gombe famous worldwide, the blond capuchins modify sticks to gather termites from trees; however, according to the study published in Biology Letters the blond capuchins use two techniques never witnessed before: twisting the stick when inside the termite nest and tapping the nest before inserting the stick.
New species of zombie-creating fungi discovered
(03/02/2011) As everyone knows, human zombies are created when an uninfected human is bitten by a member of the brain-craving undead. But what about ant zombies? Yes, that's right: ant zombies.
From Cambodia to California: the world's top 10 most threatened forests
(02/02/2011) Growing populations, expanding agriculture, commodities such as palm oil and paper, logging, urban sprawl, mining, and other human impacts have pushed many of the world's great forests to the brink. Yet scientists, environmentalists, and even some policymakers increasingly warn that forests are worth more standing than felled. They argue that by safeguarding vulnerable biodiversity, sequestering carbon, controlling erosion, and providing fresh water, forests provide services to humanity, not to mention the unquantifiable importance of having wild places in an increasingly human-modified world. Still, the decline of the world's forests continues: the FAO estimating that around 10 million hectares of tropical forest are lost every year. Of course, some of these forests are more imperiled than others, and a new analysis by Conservation International (CI) has catalogued the world's 10 most threatened forests.
Seven Brazilian bird species granted endangered status
(12/29/2010) The US Fish and Wildlife service voted recently to designate several rare bird species as endangered under the US Endangered Species Act. The designation becomes effective on January 27, 2011 and will protect against the trade of, increase conservation funding to, and promote habitat safeguards of seven of the most imperiled species in Brazil.
Forest fragment climate not driven by edge-effect
(12/19/2010) Examining ten forest fragments in Brazil's Atlantic Forest, researchers have undercut the theory that the climate of forest fragment' is driven by the edge-effect. Writing in mongabay.com's open source journal Tropical Conservation Science, researchers found that edge-effect was too simple to explain the microclimate of isolated forest fragments from 3 to 3,500 hectares large, each at least 80-years-old.
2,700 sq km of Brazil's most endangered rainforest destroyed in 8 years
(12/03/2010) 270,000 hectares of the Mata Atlântica, Brazil's most threatened ecosystem, was cleared between 2002 and 2008, reports a new assessment by the Brazilian Institute of Environment and Natural Resources (IBAMA). Less than 8 percent of the Atlantic forest—famed for its biodiversity—remains.
Is Brazil’s Sustainable Development Really Sustainable?
(09/26/2010) Sustainable development seems to have left the realms of institutional debate in Brazil and has emerged into a reality for businesses to remain competitive in their markets. It is also being used as a tool to stimulate the country’s economic growth. A notable example of this is hydroelectricity, as the country has strived for many years to generate electricity in innovative ways, rather than relying on the use of fossil fuels. Companies are also voluntarily signing up and engaging in Brazil’s GHG Protocol Program with a view to reduce carbon emissions and businesses large and small are leading on sustainable business practices. While Brazil has received a lot of respect for this forward thinking approach to sustainability, they have also been heavily criticized for hydro projects since the 1980s; in recent months the target has notably been the decision to move forward with the plan to build 3 dams on the Xingu River, which lies in the Amazon Basin.
U.S. signs debt-for-nature swap with Brazil to protect forests
(08/13/2010) The United States will cut Brazil's debt payments by $21 million under a debt-for-nature that will protect the Latin American country's endangered Atlantic Rainforest (Mata Atlantica), Caatinga and Cerrado ecosystems.
Controversial changes to Brazilian forest law passes first barrier
(07/08/2010) An amendment to undermine protections in Brazil's 1965 forestry code has passed it first legislative barrier, reports the World Wide Fund for Nature-Brasil (WWF). Yesterday the amendment passed a special vote in the Congress's Special Committee on Forest Law Changes.
Amazon and Atlantic Forest under threat: politicians press to dilute Brazil's forestry law
(07/01/2010) A group of Brazilian legislatures, known as the 'ruralistas', are working to change important aspects of the Brazil's landmark 1965 forestry code, undermining forest protection in the Amazon and the Mata Atlantica (also known as the Atlantic Forest) and perhaps heralding a new era of booming deforestation. The ruralistas, linked to big agribusiness and landowners, are taking aim at the part of the forestry code that requires landowners in the Amazon to retain 80 percent of their land area as legal reserves, arguing that the law threatens agricultural development.
New protected areas established in Brazil's fragmented Atlantic Forest
(06/17/2010) Brazil has designated an additional 65,070 hectare (161,000 acres) of land to be protected in the Mata Atlantica, or Atlantic Forest. The land is split between four new protected areas and an expansion of a national park.
When it comes to Yellow Fever, conserving howler monkeys saves lives
(03/29/2010) Abundant and diverse wildlife help people in many ways: for example bees pollinate plants, birds and mammals disperse seeds, bats control pest populations, and both plants and animals have produced life-saving medicines and technological advances. But how could howler monkeys save people from a Yellow Fever outbreak? A new study in the open-access journal Tropical Conservation Science explores the link between howler monkeys, mosquitoes, and humans during a recent yellow fever outbreak in the state of Rio Grande do Sul, Brazil.
Finding forest for the endangered golden-headed lion tamarin
(03/29/2010) Brazil's golden-headed lion tamarin is a small primate with a black body and a bright mane of gold and orange. Listed as Endangered by the IUCN Red List, the golden-headed lion tamarin (Leontopithecus chrysomelas) survives in only a single protected reserve in the largely degraded Atlantic Forest in Brazil. Otherwise its habitat lies in unprotected patches and fragments threatened by urbanization and agricultural expansion. Currently, a natural gas pipeline is being built through prime tamarin habitat.
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'.
Brazil may ban sugarcane plantations from the Amazon, Pantanal
(09/18/2009) Brazil will restrict sugarcane plantations for ethanol production from the Amazon, the Pantanal, and other ecologically-sensitive areas under a plan announced Thursday by President Luiz Inacio Lula da Silva's administration, reports the Associated Press.
Golden lion tamarins play key role in seed dispersal in Brazil's Mata Atlantica
(08/10/2009) Golden lion tamarins play an important role in seed dispersal in Brazil's Mata Atlantica, report researchers writing in the the journal Tropical Conservation Science.
REDD shouldn't neglect biodiversity say scientists
(07/30/2009) Schemes to mitigate climate change by protecting tropical forests must take into account biodiversity conservation, said two leading scientific organizations at the conclusion of a four day meeting in Marburg, Germany.
Destruction of Brazil's most imperiled rainforest continues
(05/31/2009) More than 100,000 hectares of Brazil's most threatened ecosystem was cleared between 2005 and 2008, reports a study by the Fundação SOS Mata Atlãntica and the National Institute for Space Research (INPE). The "Atlas of Mata Atlântica Remnants", released May 26, assessed the extent of the Mata Atlântica (Atlantic Forest) across 10 of the 17 states where the coastal rainforest occurs. It found that an 102,938 hectares were destroyed during the three year period. The annual loss of 34,121 hectares per year was 2.4 percent lower than the 34,965 ha recorded from the 2000-2005 period.
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.
Brazil moves to protect and restore endangered Atlantic rainforest
(11/22/2008) Brazilian president Luiz Inacio Lula da Silva has signed a decree to protect and restore critically endangered rainforest along the country's Atlantic coast, reports the Associated Press.
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.
Rare golden primates help speed recovery of endangered Brazilian forest
(06/09/2008) The endangered golden lion tamarin — a flagship species for conservation efforts in Brazil's highly threatened Atlantic Forest or Mata Atlantica — plays an important role in seed dispersal, thereby helping forest regeneration, according to research published in the June issue of the open access e-journal Tropical conservation Science.
No sacrifices to ending deforestation in the Amazon, only gains
(04/29/2008) Regular columnist and co-creator of Brazil's environmental news website, O Eco, Sergio Abranches has great credibility in Brazil's eco-awakening. A professor of political science, Abranches uses his unique talents to reach a widening audience in Brazil for environmental, energy, and climate change news and discussion. He speaks expertly on any number of topics: from Amazonian deforestation to the current food crises to economic and political transformations for a warming world.
A billion trees to be planted in Brazil's Atlantic Forest over the next 7 years
(04/22/2008) A billion trees to be planted in the Atlantic Forest over the next seven years. The Nature Conservancy has begun a program to plant a billion trees in Brazil's dwindled Atlantic Forest. The Atlantic Forest used to cover Brazil's long coast, but today only seven percent of the forest remains. Both the megacities of Sao Paulo (the world's fifth largest city) and Rio de Janeiro have emerged and grown in what used to be tropical forest. Yet, the forest remaining retains an incredible bio-diversity much of it endemic.
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.
Migrating frogs fare poorly when habitat altered
(12/19/2007) Habitat loss and fragmentation are putting amphibians already threatened by climate change, pesticides, alien invasive species, and the outbreak of a deadly fungal infection at greater risk of extinction, reported a study published in Science last week.
Brazil's threatened Atlantic forest may be more resilient than thought
(09/06/2007) The Atlantic forest of Brazil, one of the world's most threatened biodiversity hotspots, may have served as a critical refuge for biodiversity during the ice ages. The findings suggest that despite being reduced to just 8 percent of its original extent due to agriculture and urban expansion, the Atlantic forest may be capable of recovery. In other words, the Atlantic forest may be more resilient to change than previously believed.
Birds follow racoon-like coati to find food
(03/08/2007) A number of rainforest bird species are known to follow columns of army ants eating insects and other animals as they try to escape the marauding ants. Now the behvaior has been documented in birds that follow the coatimundi, a racoon-like mammal, as it forages in the rainforest.
