10 Feb 2014: New Plant Found in Andes
Supports up to 50 Species, Researchers Say

Researchers working in the Ecuadorian Andes have discovered a new species of black pepper plant that is a nexus of biodiversity. The plant, named Piper kelleyi, supports roughly 40 to 50 insect species, the scientists estimate, many of which are entirely dependent on the
P. kelleyi caterpillar
Specialist herbivore Eios feeds on P. kelleyi
plant for survival. P. kelleyi produces chemical compounds that are known to deter most herbivores, but a single type of caterpillar has adapted to overcome the toxicity of the plant's defenses. That caterpillar, in turn, is preyed upon by species of wasps and flies dependent on that specific caterpillar species — and ultimately the plant — for survival. Altogether, an assemblage of up to 50 species of herbivorous and predatory insects are dependent on P. kelleyi, the researchers report in the journal PhytoKeys.


06 Feb 2014: Maps Show Tropical Corridors
Important to Wildlife As Climate Changes

A new set of maps highlights the importance of habitat corridors in helping wildlife deal with the effects of climate change and deforestation. The series of maps shows more than 16,000 habitat corridors— swaths of

land that connect forests or protected areas and allow animals to move between them — in tropical regions of Africa, Southeast Asia, and South America. High-resolution data on biodiversity, endemism, and vegetation density allowed the researchers, led by Patrick Jantz of the Woods Hole Research Center, to determine which corridors are most important for maintaining biodiversity under changing climate conditions. The maps also highlight which corridors are most important for sequestering carbon and averting carbon emissions associated with deforestation. Researchers hope the findings will help guide wildlife protection plans and serve as a framework prioritizing the conservation of habitat corridors.


28 Jan 2014: Peru Park Holds Record
Reptile and Amphibian Diversity, Study Finds

A new study crowns Peru's Manu National Park as the place with the world's most diverse collection of reptiles and amphibians — 287 species in all. The park's 155 amphibian and 132 reptile species outnumber those in Ecuador's Yasuní National Park, which, with 271 reptile

and amphibian species, was previously believed to contain the world's most diverse collection of reptiles and amphibians. Although Manu National Park represents only 0.01 percent of the world's land area, it houses 2.2 percent of all amphibian species and 1.5 percent of all reptile species, the researchers note. They attribute the rich diversity to the park's elevation gradient, which spans the Western Amazon's tropical rainforest up through high Andean cloud forests, providing a wide range of habitats. Manu also has record bird diversity — with 1,000 species, or 10 percent of the world's total species — and tremendous butterfly diversity, with 1,200 species. Scientists say the inventory of the national park's richness is far from complete. DNA analyses, frog call studies, and other techniques will likely reveal even more diversity, the authors note in the journal Biota Neotropica.

The rate of deforestation is equal to losing 68,000 soccer fields of forest every day for the past 13 years, or 50 soccer fields every minute, says the World Resources Institute. Brazil, once responsible for a majority of the world's tropical forest loss, is now the global leader in scaling back forest destruction, cutting its deforestation rate in half over the past decade, researchers report in Science. Over the same period, Indonesia has more than doubled its annual rate of forest loss, despite a supposed 2011 Indonesian government moratorium on new logging licenses.


22 Oct 2013: Southern Amazon Rainforest
In Danger as Dry Season Expands, Study Says

The dry season in the southern part of the Amazon rainforest is lasting three weeks longer than it did 30 years ago, putting the forest at higher risk for fires and tree mortality, according to new research from the University of Texas. The most likely culprit is global

warming, says lead researcher Rong Fu. Even if future wet seasons become wetter, rainforest soil can only hold so much water, Fu explained. That water must sustain the forest throughout the entire dry season, and as the dry season lengthens the rainforest becomes increasingly stressed, vegetation growth slows, and the risk of fire rises. During a severe drought in 2005, the Amazon actually released a large amount of carbon dioxide into the atmosphere, rather than acting as a net carbon sink. Should dry seasons continue to expand, conditions like those in 2005 could become the norm, accelerating the buildup of CO2 in the atmosphere, the researchers wrote in the Proceedings of the National Academy of Sciences.


07 Oct 2013: Nutrient Recycling by Sponges
Is Vital in Sustaining Reefs, Study Says

Sponges are the unsung heroes of coral reefs, helping the vibrant ecosystems thrive in the marine equivalent of a desert, a Dutch team working in the Caribbean has found. Scientists had long questioned how reefs, some
Caribbean sponges
of the most productive communities on earth, were able to survive in low-nutrient tropical seas. Bacteria help recycle some nutrients, but the so-called "microbial loop" can't account for the high rates of carbon, nitrogen, and phosphorous recycling needed to maintain a coral reef, researchers say. Sponges fill that void by drawing in plankton and organic matter expelled by the corals and shedding cells that other reef organisms ingest as food, the researchers report in Science. The "sponge loop," as the Dutch team calls the process, recycles 10 times more organic material than bacteria do and produces as many nutrients as all other primary producers in a coral reef combined, they say.

The project, Google Street View Oceans, has already surveyed a 150-kilometer stretch of the Great Barrier Reef and is now working on reefs in the Caribbean. "Only 1 percent of humanity has ever dived on a coral reef, and by making the experience easily accessible the survey will help alert millions of people around the world to the plight of coral reefs," said Ove Hoegh-Guldberg, a marine biologist at the University of Queensland in Australia who is leading the survey. Image recognition software will log the distribution and abundance of marine organisms, and the researchers hope "citizen scientists" viewing the reefs will help assess other key measures of reef health.


16 Aug 2013: Ecuador Abandons Moratorium
On Oil Drilling in Biodiverse Yasuni Park

The Ecuadorian government has abandoned its moratorium on oil drilling in Yasuni National Park as a proposal to protect the park with the help of international donations fell apart. In a nationally televised speech, President Rafael Correa blamed the failure of the ambitious conservation plan on a lack of funds, saying that a UN-administered trust fund had raised only $13 million of the $3.6 billion target. Located in eastern Ecuador, where the Amazon basin ascends into the Andes, Yasuni is home to an unprecedented number of animal and plant species. According to a 2010 study, one section of the park held at least 200 species of mammals, 247 amphibian and reptile species, and 550 species of birds. But Yasuni also sits atop an estimated 1 billion barrels of oil. Correa had said Ecuador would forego oil income and protect the park if foreign donors would contribute billions of dollars to compensate for the loss of oil revenue.


01 Jul 2013: Climate Change Driving
More Active El Niño Cycles, Study Says

A new analysis of tree-ring data indicates that the climate cycle known as the El Niño – Southern Oscillation (ENSO) has been more active during the latter part of the 20th century than at any other time during the past seven centuries, suggesting that global warming is affecting this climate phenomenon. Using data from 2,222 tree-ring chronologies from the tropics and mid-latitudes in both the northern and southern Hemispheres, a team of scientists determined that ENSO-related behavior in the late 20th century was far greater than the natural variability reflected in data going back to 1300. A naturally occurring climate cycle, ENSO is characterized by warmer ocean temperatures off the west coast of South America, a phenomenon that can cause major droughts, floods, and extreme weather across the Pacific. According to Jinbao Li, a scientist at the University of Hawaii and lead author of the study published in the journal Nature Climate Change, greenhouse gases are altering the planet’s radiation balance and thus intensifying ENSO cycles.

hotspots with a level of detail they say is 100 times finer than previous assessments. Using the latest data on more than 21,000 species of mammals, amphibians, and birds, the maps produced by North Carolina State University researchers provide a snapshot of biodiversity health at a 10-kilometer-by-10-kilometer scale, comparable to the geographic scale at which critical conservation decisions are made. The color-coded maps reveal patterns of biodiversity for the different types of species. Researchers hope the information will help policymakers make best use of scarce conservation resources to protect the world’s most vulnerable species. The paper was published in the Proceedings of the National Academy of Sciences.


26 Jun 2013: Exposure to Lead Costs
Developing Nations $1 Trillion Annually

The exposure of children to toxic lead, and the subsequent declines in IQ and earning potential, costs the developing world nearly $1 trillion annually, according to a new report. Based on the average lead levels in children under the age of 5, researchers from New York University found that Africa suffers the greatest costs from lead exposure, losing an estimated $137.7 billion annually, or about 4 percent of its gross domestic product (GDP). In Latin America, the costs are about $142.3 billion, the study found, while in Asian nations the costs are about $699.9 billion. By comparison, the annual costs in the U.S. and Europe, where exposure to lead has decreased significantly in recent decades, are about $50 billion and $55 billion, respectively. The report said lead consumption has increased worldwide since the early 1970s, largely because of rising demand for lead batteries. The study was published in Environmental Health Perspectives.

in response to warming temperatures in the future, according to a new study. In an analysis of how nearly 3,000 species of mammals, birds, and amphibians in the Western Hemisphere will have to travel to find more hospitable climes — and the human-built barriers, such as cities and agricultural land, that could stand in their way — scientists from the University of Washington found that some regions will see far more animal movement than others. In the southeastern U.S., the Appalachian Mountains are expected to provide a conduit for species movement, as are northern regions of the eastern U.S., including the area around the Great Lakes, the study found. According to the study, published in Ecology Letters, the findings can help guide conservation and land use planning along these critical migration corridors.

Major questions remain, however, about whether the canal will ever be built. Environmental advocates warn that water needed to operate the massive infrastructure project would deplete the region’s freshwater supplies.


06 Jun 2013: Carbon Emissions in Brazil
Dropped 39% from 2005 to 2010, Report Says

Greenhouse gas emissions in Brazil fell by nearly 39 percent from 2005 to 2010, largely because of reductions in the amount of forest loss, according to a new government report. Overall, Brazil emitted the equivalent of 1.25 billion tons of carbon dioxide in 2010, which was more than 10 percent lower than 1990 levels. About 76 percent of the reductions were the product of a dramatic decline in deforestation across the Amazon and surrounding savannahs, according to the government inventory. That decline was driven by the country’s conservation policies, including stricter enforcement of land use laws, expansion of protected regions, and stronger local incentives to achieve environmental goals. For the first time, agriculture accounts for the largest share of emissions. In fact, rising emissions from agriculture and the energy sector threaten to offset improvements achieved through reduced forest loss, experts warn.


23 Apr 2013: Conservation of Forests
Can Prevent Malaria Spread, Study Says

The conservation of woodlands and biodiversity can actually help prevent the spread of malaria in tropical forests, a new study says. Using a mathematical model of different conditions in a forest region of southeastern Brazil, scientists found that the circulation of the parasite Plasmodium vivax — which is associated with 80 million to 300 million malaria cases worldwide — is likely to decrease in less developed forests where populations of non-malarial mosquitoes and warm-blooded animals are abundant. While no malaria cases have been reported in 30 years within the biodiverse study area, located in the Atlantic Forest, researchers say a primary malaria mosquito is found nearby. According to their study, published in the journal PLoS Neglected Tropical Diseases, the findings suggest that malarial and non-malarial mosquito populations are likely to compete for blood feeding, and that the animals act as “dead-end reservoirs” of the malaria parasite. “These aspects of biodiversity that can hinder malaria transmission are services provided by the forest ecosystem,” Gabriel Zorello, an epidemiologist at the University of Sao Paulo and lead researcher of the study, told ScieDev.Net.


10 Apr 2013: New Satellite-Based System Will
Track Illegal Deforestation in Real Time

A coalition of organizations has unveiled a digital tool its developers say will help governments, environmental groups, and local communities monitor illegal logging in the world’s forest regions in close to real time. Using satellite technology, data sharing, and a global network of local contributors, the so-called Global Forest Watch 2.0 system will enable users to track forest loss that has occurred within the last 30 days and allow local forest managers to upload geo-referenced photographs to support data on deforestation. Developed by the World Resources Institute (WRI) and other contributors — including Google, the University of Maryland, and the United Nations Environment Program — the technology was unveiled this week at a UN forum on forests and will be available next month. WRI hopes the system will allow government leaders and companies to make more timely forest management decisions.


20 Feb 2013: Camera Trap in Amazon
Gives Stunning Glimpse of Species Diversity

Using footage from a camera trap trained on a single “colpa” salt lick in the remote jungle of the western Amazon, a Peru-based conservationist has captured a rare glimpse into the region’s robust biodiversity, documenting an array of species, some of which are threatened, in an area now targeted by loggers, miners, and other developers. During a four-week period, Paul Rosolie’s camera collected footage of dozens of species, including a troop of howler monkeys, a giant anteater, and a host of big cats — including jaguars, pumas, and ocelots — constantly on the hunt for prey. In a short film, Rosolie, a field director at a research station for Tamandua Expeditions, documents a wide array of wildlife in a region of the lower Las Piedras River in Peru.

According to the GNP website, the discovery suggests the possible existence of additional hybrid tortoises, or even “possibly-pure Pinta” giant tortoises, in the Galapagos. The results of the study will be published in the journal Biological Conservation.

They are now seeking government permission to conduct cloning experiments. According to Embrapa’s Carlos Frederico Martins, the group is not looking at the cloning as a conservation strategy and does not intend to release the animals into the wild.


10 Oct 2012: U.S. Supreme Court Refuses
Chevron Challenge of Ecuador Damages

The U.S. Supreme Court has refused to hear Chevron Corp.’s challenge of an $18.2 billion judgment issued by an Ecuadorian court over large-scale damages caused by oil drilling in the Amazon. The Supreme Court decision is the latest development in a long legal battle that led to a ruling last year by an Ecuadorean court that Chevron had to pay the damages for massive oil dumping by Texaco, which Chevron acquired in 2001. Chevron was challenging a ruling by the 2nd U.S. Circuit Court of Appeals in New York that would have effectively opened the way for worldwide enforcement of the judgment against Chevron. An Ecuadorean court found that an oil consortium run by Texaco dumped billions of gallons of oil and toxic sludge in the Amazon rainforest from 1964 through 1992, badly polluting water supplies and causing health problems among some of the 30,000 plaintiffs in the Lago Ario region. Chevron vowed to continue to fight the Ecuadorean court’s decision, which it called “fraudulent” and tainted by judicial misconduct. Chevron contends that the decision is not enforceable under New York law.


01 Oct 2012: Organized Crime Groups Drive
Increase in Illegal Logging, Report Says

Illegal logging accounts for 15 to 30 percent of the global logging trade, with an increasing number of illegal operations in the world’s tropical regions being driven by organized crime, a new report says. According to the report, released by the United Nations Environment Program (UNEP) and INTERPOL, the illegal logging trade is now worth between $30 billion and $100 billion each year and is undermining global efforts to protect forests in the world’s most important tropical regions, including the Amazon, central Africa, and Southeast Asia. “Illegal logging is not on the decline, rather it is becoming more advanced as cartels become better organized, including shifting their illegal activities in order to avoid national and local police efforts,” wrote Achim Steiner and Ronald Noble, the heads of UNEP and INTERPOL, respectively. In the Brazilian state of Pará, for example, illegally obtained permits allowed logging cartels to steal an estimated 1.7 million cubic meters of forest in 2008. A year later, Brazilian investigators uncovered a scam involving 3,000 companies illegally exporting logged timber as allegedly “eco-certified” wood.


06 Sep 2012: Destruction of Tropical Forests
Reduces Regional Rainfall, Study Says

A new study has found that destruction of the world’s tropical forests may significantly reduce regional rainfall across large regions, a phenomenon researchers say could have devastating effects for people living in and around the Amazon and Congo basins. Using satellite observations of rainfall and vegetation, as well as atmospheric wind flow patterns, researchers from the University of Leeds and the NERC Center for Ecology & Hydrology found that across 60 percent of the Amazon and Congo rainforests, air passing over extensive forest areas produces twice as much rain as air passing over areas with little vegetation. According to their findings, published in the journal Nature, this effect in some cases can increase rainfall thousands of miles away. After combining these findings with projected deforestation rates and current trends, the researchers calculated that tropical forest loss could reduce rainfall across the Amazon basin during the wet season by 12 percent by 2050, and 21 percent during the dry season.


30 Aug 2012: Brazilian Deforestation
Falls Sharply in Past Eight Years

Deforestation in the Brazilian Amazon fell by 77 percent from 2004 to 2011, but carbon emissions did not drop as steeply because of complex processes revealed during on-the-ground studies, scientists say. While analysis of satellite images showed the three-quarters drop in deforestation, researchers said that several factors — including the slow decay of roots and the later burning of wood biomass — meant that carbon emissions from deforestation fell by 57 percent during the same period, according to a study published in the journal Global Change Biology. Another reason for the 20-percent lag in carbon emissions reductions is that logging in recent years has been moving into denser Amazon forests, so even the reduced amount of deforestation is leading to higher carbon emissions, researchers said. U.S. scientists praised their Brazilian colleagues for the sophisticated new techniques used to tease out the differences between reduced deforestation and lagging emissions reductions. “That’s where you’d like the rest of the world to be, where Brazil is,” said Richard Houghton of the Woods Hole Research Center.


15 Aug 2012: Belo Monte Dam Halted By

during the environmental assessment process. In a ruling issued Tuesday, Judge Souza Prudente of the Federal Tribunal of Brazil’s Amazon region found that no consultations were held with local communities before Congress approved what would be the world’s third-largest dam project. The $16 billion project, which is expected to produce 11,000 megawatts of energy, would flood 260 square miles of rainforest in Brazil’s Para state and displace more than 20,000 people who depend on free-flowing rivers for their livelihoods. “Legislators can only give the go-ahead if the indigenous communities agree with the project,” Prudente wrote. The developer of the project, Norte Energia, will be fined $250,000 per day if construction on the project continues. The company says it will appeal the decision.

15 Aug 2012: Wildlife Vanishing in Brazil’s
Fragmented Atlantic Forest, Study Says

The fragmentation of tropical forests in eastern Brazil as a result of agricultural expansion and other human activities has decimated biodiversity even within the pockets of forest that still remain, a new study has found. Using wildlife surveys and interviews conducted at 196 forest fragments across a 253,000-square-kilometer region inside Brazil’s Atlantic Forest, a team of researchers estimated that only about 22 percent of the animals that once inhabited the region are still there — far lower than earlier estimates. According to their findings, published in the journal PLoS ONE, white-lipped peccaries have been “completely wiped out,” while jaguars, lowland tapirs, woolly spider-monkeys and giant anteaters are essentially extinct. The loss of wildlife has even extended to areas where forest canopies are still relatively intact, said Carlos Peres, an ecologist at the University of East Anglia and lead author of the study. While the Atlantic Forest once covered more than 1.5 million square kilometers, about 90 percent has been cleared for agriculture, pasture, or urban expansion. Most remaining patches of forest, researchers say, are about the size of a football field.


Interview: The Need to Think Big
In Global Conservation Efforts

Steven E. Sanderson, who stepped down as president and CEO of the Wildlife Conservation Society (WCS) this summer, has seen the good, the bad, and the ugly in his 12 years as head of one of the world’s largest
conservation groups. Although global emissions have soared and deforestation has intensified, the WCS has savored some victories, including helping set aside 10 percent of Gabon in a system of national parks, acquiring key habitat in Chile, and carrying out successful conservation projects in strife-torn nations such as South Sudan, Afghanistan, and the Republic of Congo. In an interview with Yale Environment 360, Sanderson discusses the importance of not just creating protected areas but actively managing them; the need for conservation groups to coordinate their efforts across regions facing intense development pressure, such as the western Amazon; and the importance of enlisting zoos, such as WCS’s Bronx Zoo, to help protect endangered species and reintroduce them into the wild.

07 Aug 2012: New Bird Species Discovered
In Cloud Forest of Eastern Andes

A team of researchers says it has identified a new bird species, a barbet marked by its colorful scarlet breast and black mask, in the eastern Andes of Peru. The bird, which scientists named the Sira barbet (Capito fitzpatricki), was discovered during a 2008 expedition,

led by recent Cornell University graduates, to a remote ridge in the Cerros del Sira range. Although scientists recognized that the bird was closely related to the scarlet-banded barbet, subsequent genetic tests confirmed that it is a distinct species within the barbet family, distinguishable by the differences in color on its flanks, lower back and thighs, and its dark scarlet breast band. The researchers believe the bird may only be found in a 30-kilometer region of montane cloud forest within the range, located on an outlying ridge of the Andes. The scientific name, Capito fitzpatricki, was selected to honor John W. Fitzpatrick, a former executive director of the Cornell Lab of Ornithology who named seven bird species in Peru during the 1970s and 1980s. The bird is described in the July 2012 issue of The Auk, a publication of the American Ornithologists’ Union.


10 Jul 2012: Corals Facing Open Ocean
More Vulnerable to Warming, Study Finds

U.S. scientists say coral reef systems exposed to the open ocean are most vulnerable to warming ocean temperatures. In a new study, researchers at the University of North Carolina write that three distinct coral zones located within the Mesoamerican Barrier Reef System in Central America — including the foreef (closest to the ocean), the nearshore (closest to the shore), and the backreef (directly behind the reef crest) — saw an increase in average summer sea surface temperatures from 1982 to 2008. But while they observed a decline in skeletal growth in corals facing the ocean during that period, coral growth rates in the other two zones remained relatively stable. According to their findings, published in the journal Nature Climate Change, the ocean-facing corals were more vulnerable to warming conditions because historically they had experienced cooler and more stable seawater. “However, because backreef and nearshore coral colonies have historically been exposed to warmer and more variable seawater temperatures, they seem to be less affected,” said Karl Castillo, a postdoctoral researcher at UNC and lead author of the study.


29 Jun 2012: Recent Policies May Undermine
Brazil’s Green Progress, Scientists Say

Recent policies enacted by the Brazilian government — including changes to its Forest Code and a push to build 30 new dams in the Amazon region — threaten to undermine critical environmental progress made by the nation over the last two decades, scientists say. In a declaration published after its annual meeting in Bonito, Brazil, the Association for Tropical Biology and Conservation (ATBC) stated that government policies to reduce deforestation and protect indigenous lands had made Brazil a global conservation model over the last two decades. “But recent developments raise concerns,” said John Kress, a botanist at the Smithsonian Institution who is executive director of the ATBC. The group cited recent changes to Brazil’s forest protection laws that they say favor agribusiness and will likely increase deforestation in the Amazon, as well as numerous large-scale dam projects that will interfere with critical fish migration routes and flood vast areas of rainforest and indigenous communities.
