Brazil to test drones in monitoring the Amazon rainforest
Brazilian municipalities are planning to use drones to map properties and monitor forest cover as they move to step up enforcement of the country's Forest Code, reports The Financial Times.
Brazil strips protected status from 5.2M ha
While Brazil led the world in establishing new protected areas in recent years, it has also stripped legal protected status from some 5.2 million hectares (12.8 million acres) of land, finds a new study published in the journal Conservation Biology.
Nearly a thousand environmental activists murdered since 2002
At least 908 people were murdered for taking a stand to defend the environment between 2002 and 2013, according to a new report today from Global Witness, which shows a dramatic uptick in the murder rate during the past four years. Notably, the report appears on the same day that another NGO, Survival International, released a video of a gunman terrorizing a Guarani indigenous community in Brazil.
Emissions from rainforest logging average 16% of those from deforestation
Carbon emissions from selective logging operations in tropical rainforests are roughly a sixth of those from outright forest clearing, finds a new study that evaluated 13 forestry concessions in six countries. The study analyzed carbon losses from elements of logging operations, including timber extraction, collateral damage to surrounding vegetation, and logging infrastructure like roads and skid trails.
Will yellow fever drive brown howler monkeys to extinction in Argentina?
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.
Revealed for the first time: the surprising biodiversity of algae 'reefs'
Most people are familiar with coral reefs, but very few have ever heard of their algal equivalent – rhodolith beds. Yet, these structures provide crucial habitat for many marine species. In the first study of its kind, published in mongabay.com’s Tropical Conservation Science, researchers unveil just how important these beds are for bottom-dwelling organisms, and the species that depend on them.
Next big idea in forest conservation? Quantifying the cost of forest degradation
How much is a forest really worth? And what is the cost of forest degradation? These values are difficult to estimate, but according to Dr. Phillip Fearnside, we need to do a better job. For nearly forty years, Fearnside has lived in Amazonia doing ecological research, looking at the value of forests in terms of environmental or ecosystem services such as carbon storage, water cycling, and biodiversity preservation. Fearnside then works to convert these services into a basis for sustainable development for rural populations.
Controversial Amazon dams may have exacerbated biblical flooding
Environmentalists and scientists raised howls of protest when the Santo Antônio and Jirau Dams were proposed for the Western Amazon in Brazil, claiming among other issues that the dams would raise water levels on the Madeira River, potentially leading to catastrophic flooding. It turns out they may have been right: last week a federal Brazilian court ordered a new environmental impact study on the dams given suspicion that they have worsened recent flooding in Brazil and across the border in Bolivia.
Sharp jump in deforestation when Amazon parks lose protected status
Areas that have had their protected status removed or reduced have experienced a sharp increase in forest loss thereafter, finds a new study published by Imazon, a Brazilian NGO.
Is Brazil's epic drought a taste of the future?
With more than 140 cities implementing water rationing, analysts warning of collapsing soy and coffee exports, and reservoirs and rivers running precipitously low, talk about the World Cup in some parts of Brazil has been sidelined by concerns about an epic drought affecting the country's agricultural heartland.
Two new wasp species found hidden in museum collections
Scientists have identified two new wasp species, years after the specimens were first collected from the wild. The two new species, Abernessia prima and Abernessia capixaba, belong to the rare pompilid genus Abernessia, and are believed to be endemic to Brazil. They made the discovery while examining spider wasp collections from museums in Brazil and Denmark, and published their findings in the journal ZooKeys.
Helping the Amazon's 'Jaguar People' protect their culture and traditional wisdom
Tribes in the Amazon are increasingly exposed to the outside world by choice or circumstance. The fallout of outside contact has rarely been anything less than catastrophic, resulting in untold extinction of hundreds of tribes over the centuries. For ones that survived the devastation of introduced disease and conquest, the process of acculturation transformed once proud cultures into fragmented remnants, their self-sufficiency and social cohesion stripped away, left to struggle in a new world marked by poverty and external dependence
Photos: mass turtle hatching produces over 200,000 babies
Biologists recently documented one of nature's least-known, big events. On the banks of the Purus River in the Brazilian Amazon, researchers witnessed the mass-hatching of an estimated 210,000 giant South American river turtles (Podocnemis expansa). The giant South American river turtle, or Arrau, is the world's largest side-necked turtle and can grow up to 80 centimeters long (nearly three feet).
Brazilian soy industry extends deforestation moratorium
Soy traders and producers in the Brazilian Amazon agreed to extend a moratorium on soybeans produced in recently deforested areas for another year, reports Greenpeace.
Next big idea in forest conservation? Connecting forest fragments
Dr. Stuart Pimm is an expert in extinctions: why they happen, how fast they happen, and how they can be prevented. Reconnecting forest fragments and avoiding fragmentation, according to Pimm, are among the most crucial things we can do to conserve global biodiversity. His organization SavingSpecies identifies areas at-risk for extinctions and helps local organizations fundraise so they can protect and restore habitats and safeguard biodiversity.
New dolphin discovered in the Amazon surprises scientists
Researchers have discovered a new species of river dolphin from the Amazon. Writing in the journal Plos One, scientists led by Tomas Hrbek of Brazil's Federal University of Amazonas formally describe Inia araguaiaensis, a freshwater dolphin that inhabits the Araguaia River Basin. It is the first true river dolphin discovered since 1918.
Rainforest news review for 2013
2013 was full of major developments in efforts to understand and protect the world's tropical rainforests. The following is a review of some of the major tropical forest-related news stories for the year. As a review, this post will not cover everything that transpired during 2013 in the world of tropical forests. Please feel free to highlight anything this post missed via the comments section at the bottom. Also please note that this review focuses only on tropical forests.
Assassination 25 years ago catalyzed movement to protect the Amazon
Twenty-five years ago today, Chico Mendes, an Amazon rubber tapper, was shot and killed in front of his family at his home in Acre, Brazil at the age of 44.
Brazilian cattle producers standardize audits to exclude deforestation from supply chain
Brazil's largest cattle producers have agreed to standardize and make public their audits as part of an effort to exclude from their supply chains livestock produced via deforestation, reports Greenpeace, which has led a campaign to improve the environmental performance of the sector. The agreement on a standard auditing protocol means that the companies' progress toward eliminating deforestation will now be directly comparable.
Scientists make one of the biggest animal discoveries of the century - a new tapir
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.
Scientists: well-managed forest restoration benefits both biodiversity and people
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
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.
Top 10 Environmental Stories of 2013
1. Carbon concentrations hit 400ppm while the IPCC sets global carbon budget: For the first time since our appearance on Earth, carbon concentrations in the atmosphere hit 400 parts per million. The last time concentrations were this high for a sustained period was 4-5 million years ago when temperatures were 10 degrees Celsius higher. Meanwhile, in the slow-moving effort to curb carbon emissions, the Intergovernmental Panel on Climate Change (IPCC) crafted a global carbon budget showing that most of the world's fossil fuel reserves must be left untouched if we are to avoid catastrophic climate change.
New mountain porcupine discovered in Brazil (photos)
In Brazil's Baturite Mountains, scientists have uncovered a new species of prehensile-tailed porcupine, according to a new paper in Revista Nordestina de Biologia. Dubbed, the Baturite porcupine (Coendou baturitensis), the new species was discovered when scientists noticed significant differences between it and its closest relative, the Brazilian porcupine (Coendou prehensilis). The name prehensile-tailed refers to these porcupines long, mobile tail which they use as a fifth limb to adroitly climb trees.
Humans are not apex predators, but meat-eating on the rise worldwide
A new paper in Proceedings of the National Academy of Sciences has measured the "trophic level" of human beings for the first time. Falling between 1 and 5.5, trophic levels refer to where species fit on the food chain. Apex predators like tigers and sharks are given a 5.5 on trophic scale since they survive almost entirely on consuming meat, while plants and phytoplankton, which make their own food, are at the bottom of the scale. Humans, according to the new paper, currently fall in the middle: 2.21. However, rising meat-eating in countries like China, India, and Brazil is pushing our trophic level higher with massive environmental impacts.
Brazil could boost agriculture without destroying forests
Brazil could substantially boost its agricultural output while increasing protection of its native ecosystems, finds a new analysis published by the Climate Policy Initiative (CPI), an international think tank.
Scientists discover new cat species roaming Brazil
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.
Gold mine near controversial Belo Monte dam suspended
A gold mining project proposed near the Belo Monte dam site in the Amazon rainforest has been suspended by a Brazilian court, reports Reuters.
Why is Amazon deforestation climbing?
The 28 percent increase in deforestation in the Brazilian Amazon over last year that was reported this week is bad news, but it is not surprising. It is bad news because the decline in deforestation since 2005 has given us the single largest contribution to climate change mitigation on the planet, far surpassing the reductions in emissions achieved by any Annex 1 country under the Kyoto Protocol. Brazil’s achievement is particularly noteworthy because it did not come at the expense of agricultural production; beef and soybean production continued to grow.
New bat species discovered in Brazil leaves another at risk
A team of researchers has discovered a new species of bat in Brazil, which has put a previously known species, Bokermann's nectar bat (Lonchophylla bokermanni), at risk of extinction. Long thought to comprise one species, the bat populations of the Atlantic Forest and the Cerrado – the tropical savannah of Brazil's interior - are in fact distinct from one another, according to a new study in Zootaxa. Scientists now say the Atlantic Forest's population represents a newly described species, which they have dubbed Peracchi's nectar bat (Lonchophylla peracchii).
