(01/25/2012) Researchers have found that some frogs in Madagascar communicate by more than just sound and sight: they create distinct airborne pheromones, which are secreted chemicals used for communicating with others. A paper published in Angewandte Chemie International Edition relates that some male members of the Mantellinae family in Madagascar use large glands on their inner thighs to produce airborne pheromones. Interestingly, the pheromones are structurally similar to those produced by insects. Scientists have identified frogs producing water-borne pheromones before, but this is the first instance of airborne.
U.S. implements snake ban to save native ecosystems
(01/25/2012) Last week the U.S. Fish and Wildlife Service (USFWS) announced it was banning the importation and sale across state lines of four large, non-native snakes: the Burmese python (Python molurus bivittatus), the yellow anaconda (Eunectes notaeus), and two subspecies of the African python (Python sebae). Although popular pets, snakes released and escaped into the wild have caused considerable environmental damage especially in the Florida Everglades.
Climate and The Oceans - Princeton Primers in Climate: A Book Review
(01/25/2012) Climate and The Oceans by Dr. Geoffrey K. Vallis provides a coherent, well-articulated primer on how the oceans impact the Earth's climate. This easy-to-read illustrated book, filled with both data and accessible mathematical equations demonstrating the impact of the oceans on the Earth's climate, offers practitioners and stakeholders' state-of-the-art scientific analysis of how the oceans and climate interact that is both user friendly to the non-expert yet scientifically rigorous enough as bridge material for graduate students as they grapple with the compelling field of climate science and oceanography.
Photos: 46 new species found in little-explored Amazonian nation
(01/25/2012) South America's tiniest independent nation still hides a number of big surprises: a three week survey to the sourthern rainforests of Suriname found 46 potentially new species and recorded nearly 1,300 species in all. Undertaken by Conservation International's (CI) Rapid Assessment Program (RAP) the survey found new species of freshwater fish, insects, and a new frog dubbed the "cowboy frog" for the spur on its heel. While Suriname may be small, much of its forest, in the Guyana Shield region of the Amazon, remains intact and pristine. The Food and Agriculture Organization (FAO) estimates that 91 percent of Suriname is covered in primary forests, however this data has not been updated in over two decades.
87 marine mammals still eaten by people
(01/24/2012) Threats to marine mammals usually include climate change, drowning as by-catch, pollution, depletion of prey, but what about eating marine mammals? A new study in Biological Conservation finds that a surprising 87 marine mammals—including polar bears, small whales, and dolphins—have been eaten as food since 1990 in at least 114 countries.
Acid oceans: in some regions acidification a 'hundred times greater' than natural variation
(01/24/2012) Emissions of carbon over the last two centuries have raised the acidity of the oceans to the highest levels in 21,000 years and likely beyond, according to a new study in Nature Climate Change. The change threatens a number of marine species, including coral reefs and molluscs.
Pangolins imperiled by internet trade--are companies responding quickly enough?
(01/24/2012) You can buy pretty much anything on the internet: from Rugby team garden gnomes to Mickey Mouse lingerie. In some places, consumers have even been able to purchase illegal wildlife parts, such as ivory and rhino horn. In fact, the internet has opened up the black market wildlife trade contributing to the destruction of biodiversity worldwide. Pangolins, shy, scaly, anteater-like animals in appearance, have not been immune: in Asia the small animals are killed en masse to feed rising demand for Chinese traditional medicine, placing a number of species on the endangered list.
Sumatran elephant population plunges; WWF calls for moratorium on deforestation
(01/24/2012) The Sumatran elephant subspecies (Elephas maximus sumatranus) was downgraded to critically endangered on IUCN's Red List of Threatened Species on Tuesday, prompting environmental group WWF to call for an immediate moratorium on destruction of its rainforest habitat, which is being rapidly lost to oil palm estates, timber plantations for pulp and paper production, and agricultural use.
The Cryosphere-Princeton primers in climate: A Book Review
(01/23/2012) The Cryosphere by Dr. Shawn J. Marshall, Canada Research Chair in Climate Change, University of Calgary, is an excellent book because it summarizes leading scientific research into easily accessible chapters each one on a different component of the cryosphere. The cryosphere, which incorporates the Earth's snow and ice mass including seasonal snow, permafrost (both land-based permafrost and below water permafrost), river and lake ice, sea ice, glaciers, ice sheets, and ice shelves, is intrinsically related to global climate change. Hence, understanding how the cryosphere interacts with and is at risk because of climate change and its greenhouse gases is fundamental to developing effective policy mechanisms that mitigate climate change.
Leatherback sea turtles granted massive protected area along U.S. west coast
(01/23/2012) The U.S. federal government has designated 108,556 square kilometers (41,914 square miles) as critical habitat for the leatherback sea turtle (Dermochelys coriacea), the largest of the world's marine turtles and one of the most endangered. The protected area, around the size of Guatemala, spans coastal sea waters from California to Washington state, but does not protect the migration routes environmentalists hoped for.
Picture of the Day: Happy Year of the Dragon
(01/23/2012) Today marks the start of Chinese New Year, which this year is represented by the dragon, one of twelve animals in the Chinese zodiac.
Economic slowdown leads to the pulping of Latvia's forests
(01/23/2012) The economic crisis has pushed many nations to scramble for revenue and jobs in tight times, and the small Eastern European nation of Latvia is no different. Facing tough circumstances, the country turned to its most important and abundant natural resource: forests. The Latvian government accepted a new plan for the nation's forests, which has resulted in logging at rates many scientists say are clearly unsustainable. In addition, researchers contend that the on-the-ground practices of state-owned timber giant, Latvijas Valsts meži (LVM), are hurting wildlife and destroying rare ecosystems.
NASA: 2011 ninth warmest year yet
(01/23/2012) Despite being a strong La Niña year, which tends to be cooler than the average year, 2011 was the ninth warmest year on record and the warmest La Niña yet, according to a global temperature analysis by NASA. To date, nine of the world's ten warmest years have occurred since 2000 according to data going back to 1880.

Featured video: music in Madagascar to protest illegal logging
(01/22/2012) A new video highlights the plight of Madagascar's protected tropical forests, which are falling prey to illegal logging and foreign contractors. Featuring Razia Said, Malagasy singer and songwriter, the video shows concerts to raise awareness about illegal logging, especially near Maosala National Park.
Biofuel breakthrough: kelp could power cars
(01/20/2012) Scientists have devised a new way to produce ethanol directly from seaweed, offering the potential to generate biofuels that don't compete with terrestrial food production and won't suck up scarce freshwater, reports a study published today in Science.
Recognizing value of nature could boost income for the world's poor
(01/20/2012) The rural poor would substantially boost their income if the ecological services of the ecosystems they steward were valued and compensated by the rest of the world, claims a new study published in the journal Bioscience.
Feared extinct, obscure monkey rediscovered in Borneo
(01/20/2012) A significant population of the rarely seen, little-known Miller's grizzled langurs (Presbytis hosei canicrus) has been discovered in Indonesian Borneo according to a new paper published in the American Journal of Primatology. Feared extinct by some and dubbed one of the world's 25 most threatened primates in 2005 by Conservation International (CI), the langur surprised researchers by showing up on camera trap in a region of Borneo it was never supposed to be. The discovery provides new hope for the elusive monkey and expands its known range, but conservationists warn the species is not out of the woods yet.
Scientists discover over 19,000 new species in 2009
(01/19/2012) In 2009 researchers described and named 19,232 species new to science, pushing the number of known species on Earth to just under two million (1,941,939 species), according to the State of Observed Species (SOS). Discoveries included seven new birds, 41 mammals, 120 reptiles, 148 amphibians, 314 fish, 626 crustaceans, and 9,738 insects.
National Association of Music Merchants does 'disservice' to members by misleading them on illegal logging law, says letter
(01/19/2012) The National Association of Music Merchants is doing a 'disservice' to its members by misrepresenting the provisions and spirit of the Lacey Act, a law that aims to curb illegal logging abroad, states a letter published by a coalition of environmental groups. The letter, issued Thursday, urges the National Association of Music Merchants to reconsider its support for the RELIEF Act (HR 3210), introduced by Representatives Marsha Blackburn (R-TN), Mary Bono Mack (R-CA), and Jim Cooper (D-TN) last October. The RELIEF Act would weaken key provisions of the Lacey Act aimed to ensure that illegally sourced wood products aren't imported into the United States.
Brazil begins preliminary damming of Xingu River as protests continue
(01/19/2012) Damming of the Xingu River has begun in Brazil to make way for the eventual construction of the hugely controversial, Belo Monte dam. The Norte Energia (NESA) consortium has begun building coffer dams across the Xingu, which will dry out parts of the river before permanent damming, reports the NGO International Rivers. Indigenous tribes, who have long opposed the dam plans on their ancestral river, conducted a peaceful protest that interrupted construction for a couple hours.
Indonesia to set aside 45% of Kalimantan for conservation
(01/19/2012) Indonesian President Susilo Bambang Yudhoyono (SBY) on Thursday announced a regulation that would protect 45 percent of Kalimantan, the Indonesian part of Borneo, according to a statement issued by his office.
Geology has split the Amazon into two distinct forests
(01/19/2012) The common view of the Amazon is that it is one massive, unbroken forest. This impression is given by maps which tend to mark the Amazon by a large glob of green or even by its single name which doesn't account for regional changes. Of course, scientists have long recognized different ecosystems in the Amazon, most especially related to climate. But a new study in the Journal of Biogeography has uncovered two distinct forest ecosystems, sharply divided, caused by million of years of geologic forces.
Deforestation, climate change threaten the ecological resilience of the Amazon rainforest
(01/19/2012) The combination of deforestation, forest degradation, and the effects of climate change are weakening the resilience of the Amazon rainforest ecosystem, potentially leading to loss of carbon storage and changes in rainfall patterns and river discharge, finds a comprehensive review published in the journal Nature.
Obama rejects Keystone pipeline, but leaves door open for tar sands
(01/18/2012) The Obama administration today announced it is scrapping TransCanada's Keystone pipeline after Republicans forced a 60-day deadline on the issue in a Congressional rider. The State Department advised against the pipeline arguing that the deadline did not give the department enough time to determine if the pipeline "served the national interest." The cancellation of the pipeline is a victory for environmental and social activists who fought the project for months, but Republicans are blasting the administration.
Delayed response to Somalia famine cost thousands of lives
(01/18/2012) A hesitant response by the international community likely led to thousands of unnecessary deaths in last year's famine in East Africa finds a new report released by Oxfam and Save the Children. The report, entitled A Dangerous Delay, says that early warning systems worked in informing the international community about the likelihood of a dire food crisis in East Africa, however a "culture of risk aversion" led to months-long delays. By the time aid arrived it was already too late for many. The British government has estimated somewhere between 50,000 and 100,000 people perished in the famine, half of whom were likely children under five.
Picture of the day: nearly-extinct turtle released into the wild in Cambodia
(01/18/2012) Only around 200 southern river terrapins (Batagur affinis) survive in the wild, but today at least the species got some good news. A female terrapin was released back into the Sre Ambel River with much fanfare after being caught by a local fishermen in Cambodia.
Disease kills 6 million bats in North America
(01/18/2012) In just six years around six million bats have succumbed to white-nose syndrome in North America, according to U.S. federal researchers. The number, somewhere between 5.7 and 6.7 million bats, is far higher than past estimates of over a million. Showing up in 2006 in New York, the perplexing disease, which appears as white dust on bats' muzzles, wipes out populations while they hibernate.
Prehistoric Peruvians enjoyed popcorn
(01/18/2012) Researchers have uncovered corncobs dating back at least 3,000 years ago in two ancient mound sites in Peru according to a paper published in Proceedings of the National Academy of Sciences (PNAS). The ancient corn remnants, which proved residents were eating both popped corn and corn flour, are the earliest ever discovered in South America and may go back as far as 4,700 BCE (6,700 years ago), over fifteen hundred years before the early Egyptians developed hieroglyphics and while woolly mammoths still roamed parts of the Earth.
New book series hopes to inspire research in world's 'hottest biodiversity hotspot'
(01/17/2012) Entomologist Dmitry Telnov hopes his new pet project will inspire and disseminate research about one of the world's last unexplored biogeographical regions: Wallacea and New Guinea. Incredibly rich in biodiversity and still full of unknown species, the region, also known as the Indo-Australian transition, spans many of the tropical islands of the Pacific, including Indonesia's Sulawesi, Komodo and Flores, as well as East Timor—the historically famous "spice islands" of the Moluccan Archipelago—the Solomon Islands, and, of course, New Guinea. Telnov has begun a new book series, entitled Biodiversity, Biogeography and Nature Conservation in Wallacea and New Guinea, that aims to compile and highlight new research in the region, focusing both on biology and conservation. The first volume, currently available, also includes the description of 150 new species.
Levi's new forest policy excludes fiber from suppliers linked to deforestation
(01/17/2012) Levi Strauss & Company had issued a new policy that will exclude fiber from controversial sources from its products. The move will effectively bar Asia Pulp & Paper (APP) as a supplier, according to the Rainforest Action Network, a green group that is campaigning to reform APP's sourcing practices, which the NGO says come at the expense of rainforests in Sumatra.
Conserving Ecuador's Paramos, the alpine tundra ecosystem of the Andes
(01/17/2012) Grupo de Trabajo en Páramos del Ecuador (GTP) is a remarkable self-organized group of páramo experts that have met over the past 13 years in Quito, Ecuador. Páramo is an alpine tundra ecosystem which is located in the northern Andes of South America and adjacent southern Central America. Recently, the Grupo de Trabajo en Páramos del Ecuador published an excellent summary of their analysis from the past 13 years. Robert Hofstede, one of the editors of Páramo: Paisaje estudiado, habitado, manejado e institucionalizado, recently sat down with Mongabay.com and discussed the situation of páramo conservation in Ecuador.
Featured video: plight of orangutans highlighted with new rock song
(01/17/2012) An Indonesian rock band, Navicula, is highlighting the plight of orangutans in their native country through a new song entitled, aptly, "Orangutan." The band has created a music video for the song, including footage of a documentary, Green: The Film that follows a starving female orangutan named Green. The band "dedicated the song to encourage people to do more in orangutan conservation, to protect this endangered species."
Rainforests need massive finance, but REDD must be well-designed to succeed
(01/17/2012) A proposed mechanism to reduce greenhouse gas emissions by protecting tropical forests has evolved considerably since it started to gain momentum during the 2005 climate talks in Montreal. Known then as 'avoided deforestation', the concept was simple: pay tropical forest countries to keep their forests standing. Since then, the concept has broadened to include activities beyond strict forest conservation, including reducing logging and fire, protecting carbon-dense peatlands, encouraging better forest management practices in existing forest concessions, and promoting reforestation and afforestation. A prominent voice in the discussion around REDD since its inception is the environmental activist group Greenpeace. Mongabay recently caught up with Roman Czebiniak, Greenpeace International's Political Advisor on Climate Change and Forests, for an update on the organization's position on REDD as well as recent developments in the forest carbon policy arena.
One company behind U.S.'s top three biggest greenhouse gas emitters
(01/16/2012) The Atlanta-based Southern company owns the top three biggest sources of greenhouse gas emissions in the U.S. according to recent data released by the Environmental Protection Agency (EPA). Three of Southern's coal-fired plants—two in Georgia and one in Alabama—account for around 64.74 million metric tons of total greenhouse gas emissions, higher than all of Finland's carbon emission in 2008.
Photos: program devoted to world's strangest, most neglected animals celebrates five years
(01/16/2012) What do Attenborough's echidna, the bumblebee bat, and the purple frog have in common? They have all received conservation attention from a unique program by the Zoological Society of London (ZSL) called EDGE. Five years old this week, the program focuses on the world's most unique and imperiled animal species or, as they put it, the most Evolutionarily Distinct and Globally Endangered (EDGE) species. In the past five years the program has achieved notable successes from confirming the existence of long unseen species (Attenborough's echidna) to taking the first photos and video of a number of targeted animals (the purple frog).
Global food prices set record in 2011
(01/16/2012) Last year saw the highest average food prices since recording began in 1990, according to the Food and Agriculture Organization's (FAO) Food Price Index. The Food Price Index's average for the year was 228 points, 28 points higher than the past record set in 2008.
Featured video: tuna industry bycatch includes sea turtles, dolphins, whales
(01/16/2012) A Greenpeace video, using footage from a whistleblower, shows disturbing images of the tuna industry operating in the unregulated waters of the Pacific Ocean. Using fish aggregation devices (FADs) and purse seine nets, the industry is not only able to catch entire schools of tuna, including juvenile, but also whatever else is in the area of the net.
Elephant poachers kill unarmed wildlife ranger in Kenya
(01/16/2012) Abdullahi Mohammed, an wildlife ranger, was killed in the line of duty in Kenya this weekend by elephant poachers. A ranger with the conservation organization Wildlife Works, Mohammed was shot by poachers in Wildlife Works Kasigau Corridor project, a REDD program (Reduced Emissions From Deforestation and Degradation).
Beyoncé honored with new horse fly named after her
(01/16/2012) Musical artists, and dancer extraordinare, Beyoncé has been awarded a new honor this week: entomologists in Australia have named a new horse fly after the American singer. The new horse fly, dubbed Scaptia beyonceae, is found in Queensland's Atherton Tablelands.
How much is the life of a whale worth?
(01/16/2012) How do you end a decades-long conflict between culture and conservation? How do you stop a conflict where both sides are dug in? A new paper in Nature proposes a way to end the long and bitter battle over whaling: environmentalists could pay whalers not to whale.
Climate change may make lizards smarter, if they don't go extinct first
(01/12/2012) A new study in Biology Letters has found that warmer temperatures may make lizards smarter, even as past studies have linked a global decline in lizards to climate change.
New frog trumps miniscule fish for title of 'world's smallest vertebrate'
(01/12/2012) How small can you be and still have a spine? Scientists are continually surprised by the answer. Researchers have discovered a new species of frog in Papua New Guinea that is smaller than many insects and dwarfed by a dime. The frog trumps the previously known smallest vertebrate—a tiny fish—by nearly 1 millimeter.
Targeting methane, black carbon could buy world a little time on climate change
(01/12/2012) A new study in Science argues that reducing methane and black carbon emissions would bring global health, agriculture, and climate benefits. While such reductions would not replace the need to reduce CO2 emissions, they could have the result of lowering global temperature by 0.5 degrees Celsius (0.9 degree Fahrenheit) by mid-century, as well as having the added benefits of saving lives and boosting agricultural yields. In addition, the authors contend that dealing with black carbon and methane now would be inexpensive and politically feasible.
Cute animal picture of the day: pygmy killer whale saved after stranding
(01/12/2012) On Tuesday a female pygmy killer whale (Feresa attenuata) was found stranded on Tanjung Aru beach, in the Malaysian state of Sabah on the island of Borneo. After being moved to a swimming enclosure at a local resort for recuperation, the whale was released back into the wild with aid from the Sabah Wildlife Department, marine biologist Lindsay Porter, the local NGO LEAP, and WWF Malaysia.
Indonesia could earn billions from well-designed deforestation-reduction program, finds study
(01/12/2012) Indonesia could have earned $5 billion in revenue and avoided 1 billion tons of carbon dioxide emissions between 2000 and 2005 had a reducing emissions from deforestation and degradation (REDD+) program been in place, reports an assessment published in the journal Proceedings of the National Academy of Science.
Peruvian smugglers traffic illegal rainforest timber from Brazil to America
(01/11/2012) An investigation by Brazil's Federal Police has detailed a significant trade of illegally logged rainforest wood by Peruvian nationals making its way from northern Brazil to the U.S. and Mexico, reports O Globo.
Bycatch-reducing fish trap wins $20,000
(01/11/2012) An innovative fish trap that allows small non-target fish to escape won a new content by RARE Conservation and National Geographic to fund solutions to overfishing. Developed through studies in Curaçao and Kenya with the Wildlife Conservation Society, the trap has gaps for juvenile fish to swim out of reportedly reducing bycatch by 80 percent. The entry won a $20,000 grant.
Borneo's most elusive feline photographed at unexpected elevation
(01/11/2012) Although known to science for 138 years, almost nothing is actually known about the bay cat (Pardofelis badia). This reddish-brown wild feline, endemic to the island of Borneo, has entirely eluded researchers and conservationists. The first photo of the cat wasn't taken until 1998 and the first video was shot just two years ago, but basic information remains lacking. A new camera trap study, however, in the Kelabit Highlands of the Malaysian state of Sarawak has added to the little knowledge we have by photographing a bay cat at never before seen altitudes.
Seals, birds, and alpine plants suffer under climate change
(01/11/2012) The number of species identified by scientists as vulnerable to climate change continues to rise along with the Earth's temperature. Recent studies have found that a warmer world is leading to premature deaths of harp seal pups (Pagophilus groenlandicus) in the Arctic, a decline of some duck species in Canada, shrinking alpine meadows in Europe, and indirect pressure on mountain songbirds and plants in the U.S. Scientists have long known that climate change will upend ecosystems worldwide, creating climate winners and losers, and likely leading to waves of extinction. While the impacts of climate change on polar bears and coral reefs have been well-documented, every year scientists add new species to the list of those already threatened by anthropogenic climate change.
