Video: Incredible technology maps rainforest biodiversity in 3D
(11/26/2013) Technology that enables scientists to catalogue a rainforest's biodiversity in stunning detail by airplane was highlighted in a recent TED talk. Speaking at TED Global in Edinburgh, Scotland this past June, researcher Greg Asner explained the science behind his ground-breaking forest mapping platform: the Carnegie Airborne Observatory (CAO), an airplane packed with advanced chemical and optical sensors.
Malaysia has the world's highest deforestation rate, reveals Google forest map
(11/15/2013) Malaysia had the world's highest rate of forest loss between 2000 and 2012, according to a new global forest map developed in partnership with Google. Malaysia's total forest loss during the period amounted to 14.4 percent of its year 2000 forest cover. The loss translates to 47,278 square kilometers (18,244 square miles), an area larger than the country of Denmark.
Deforestation accelerates in Indonesia, finds Google forest map
(11/14/2013) Forest loss in Indonesia has sharply risen over the past 12 years, reports a new study published in the journal Science. The study, led by Matt Hansen of University of Maryland, finds that Indonesia lost 15.8 million hectares between 2000 and 2012, ranking it fifth behind Russia, Brazil, the United States, and Canada in terms of forest loss. Some 7 million hectares of forest regrew during the period.
Powered by Google, high resolution forest map reveals massive deforestation worldwide
(11/14/2013) Researchers today released a long-awaited tool that reveals the extent of forest cover loss and gain on a global scale. Powered by Google's massive computing cloud, the interactive forest map establishes a new baseline for measuring deforestation and forest recovery across all of the world's countries, biomes, and forest types. The map has far-reaching implications for efforts to slow deforestation, which accounts for roughly ten percent of greenhouse gas emissions produced by human activities, according to the authors of the paper that describes the tool and details its first findings.
Ultraviolet nets significantly reduce sea turtle bycatch
(11/11/2013) Bycatch, a side-effect of commercial fishing in which non-target species are accidentally caught, is linked to severe population declines in several species. Sea turtles are particularly impacted by small-scale coastal gillnetting practices, in which large nets are deployed and indiscriminately snag anything of a certain size that attempts to swim through them. However, that may soon change.
Seahorses on your iPad: new app allows anyone to track and document seahorses
(11/08/2013) Annually, approximately 13 million seahorses—live and dead—are traded around the globe. At this scale, the seahorse trade is potentially very destructive to a group of animals comprised of 48 species, 11 of which are listed by the International Union for Conservation and Nature (IUCN) as threatened with extinction.
Could camera trap videos galvanize the world to protect Yasuni from oil drilling?
(11/07/2013) Even ten years ago it would have been impossible to imagine: clear-as-day footage of a jaguar plodding through the impenetrable Amazon, or a bicolored-spined porcupine balancing on a branch, or a troop of spider monkeys feeding at a clay lick, or a band of little coatis racing one-by-one from the dense foliage. These are things that even researchers who have spent a lifetime in the Amazon may never see. Now anyone can: scientists at the Tiputini Biodiversity Station in Ecuador's Yasuní National Park have recently begun using camera trap videos to take movies of animals few will ever view in their lifetimes. The videos—following years of photo camera trapping—provide an intimate view of a world increasingly threatened by the oil industry.
DNA tests reveal new dolphin species (photos)
(10/30/2013) With the help of DNA tests, scientists have declared a new dolphin species that dwells off the coast of northern Australia. The discovery was made after a team of researchers looked at the world's humpback dolphins (in the genus Sousa), which sport telltale humps just behind their dorsal fins. While long-known to science, the new, as-yet-unnamed species was previously lumped with other humpback dolphins in the Indo-Pacific region.
Scientists identify individual lizards by their irises
(10/29/2013) Institutions and governments have been scanning human irises for years to verify one's identity—Google has been using this method since 2011—but could iris-scanning be employed on other species as well? According to a new study in Amphibia-Reptila, the answer is 'yes.' Scientists have recently employed iris scanning to visually distinguish individuals of an imperiled gecko subspecies (Tarentola boettgeri bischoffi) found on Portugal's Savage Islands off the coast of Western Sahara. l.
Gold mining in the Amazon rainforest surges 400%
(10/28/2013) The extent of gold mining in the Peruvian Amazon has surged 400 percent since 1999 due to rocketing gold prices, wreaking havoc on forests and devastating local rivers, finds a new study published in the Proceedings of the National Academy of Sciences (PNAS). The assessment, led by Greg Asner of the Carnegie Institution for Science, is based on a combination of satellite imagery, on-the-ground field surveys, and an advanced airplane-based sensor that can accurately measure the rainforest canopy and sub-canopy vegetation at a resolution of 1.1 meters (42 inches).
Wildlife drones could revolutionize aerial surveys of animal populations
(09/30/2013) In open areas, like the African savannah, scientists often estimate wildlife populations through manned aerial surveys. However a new study in mongabay.com's open access journal argues that using small drones may be more cost-effective, safer, and capable of reaching more remote areas. Researchers tested the accuracy of drone counts in Bazinga Game Ranch (NGR) in Burkina Faso.
Video of Amazon gold mining devastation goes viral in Peru
(09/26/2013) Video of illegal gold mining operations that have turned a portion of the Amazon rainforest into a moonscape went viral on Youtube after a popular radio and TV journalist in Peru highlighted the story. Last week Peruvian journalist and politician Guido Lombardi directed his followers to video shot from a wingcam aboard the Carnegie Airborne Observatory (CAO), an airplane used by researchers to conduct advanced monitoring and analysis of Peru's forests. The video quickly received more than 60,000 views on Youtube.
Protecting predators in the wildest landscape you've never heard of
(09/10/2013) The Serengeti, the Congo, the Okavango Delta: many of Africa's great wildernesses are household names, however on a continent that never fails to surprise remain vast wild lands practically unknown to the global public. One of these is the Ruaha landscape: covering 51,800 square kilometers (20,000 square miles) of southern Tanzania's woodlands and savannah, Ruaha contains the largest population of elephants in East Africa, over 500 bird species, and a wealth of iconic top predators, including cheetah, hyena, wild dogs, leopard, and—the jewel in its crown—10 percent of the world's lions. But that's not all, one of Africa's least-known and secretive tribal groups, the Barabaig, also calls Ruaha home.
$450/ha tax on deforestation could help curb forest loss in Bolivia, suggests new simulation
(09/01/2013) Levying a $450 per hectare tax on deforested lands could help curb forest clearing in Bolivia, suggests a new game-based simulation developed by researchers.
Indonesian group vows to map 30 million hectares of customary forest in 7 years
(08/28/2013) An indigenous peoples’ rights group has vowed to map millions of hectares of customary land in Indonesia, an ambitious target it hopes will help protect indigenous forests from encroachment by palm oil and pulp and paper concessions.
Google Earth presents fish-eye view of coral reefs
(08/20/2013) You can now visit up-close and personal some of the world's most imperiled ecosystems on Google Earth: coral reefs. The Google team is working with scientists to provide 360 degree panoramas, similar to Google street-view, to give armchair ecologists a chance to experience the most biodiverse ecosystems under the waves.
Deforestation alerts for Madagascar, DRC, Bolivia during Q2-2013
(08/16/2013) Loss of forest, woodland, and savanna increased sharply in Madagascar, the Democratic Republic of the Congo (DRC), and Bolivia during the second quarter of 2013, reports a new assessment by NASA scientists.
New Android app helps you identify frogs in the Western Ghats
(08/15/2013) Amphibians hop onto your Android phone in an app that focuses on ease of use. There are many among us who have gone out for a walk in the night, during the rains, and heard frogs chorusing. Or looked upon a small amphibian perched perilously by the wayside, and wondered what it is called.
Foodies eat lab-grown burger that could change the world
(08/06/2013) Yesterday at a press event in London, two food writers took a bite into the world's most unusual hamburger. Grown meticulously from cow stem cells, the hamburger patty represents the dream (or pipedream) of many animal rights activists and environmentalists. The burger was developed by Physiologist Mark Post of Maastricht University and funded by Google co-founder Sergey Brin in an effort to create real meat without the corresponding environmental toll.
Near real-time deforestation monitoring system to go global
(07/25/2013) A near real-time deforestation monitoring system will soon cover all the world's tropical forests, report the researchers behind the initiative.
Researchers produce the most accurate carbon map for an entire country
(07/22/2013) Researchers working in Panama have produced the most accurate carbon map for an entire country. Using satellite imagery and extremely high-resolution Light Detection and Ranging (LiDAR) data from airplane-based sensors, a team led by Greg Asner produced a detailed carbon map across the Central American country's forests. The map reveals variations in forest carbon density resulting from elevation, slope, climate, vegetation type, and canopy coverage.
Scientists build app to automatically identify species based on their calls
(07/16/2013) New technology makes it possible to automatically identify species by their vocalizations. The platform, detailed in the current issue of the journal PeerJ, has been used at sites in Puerto Rico and Costa Rica to identify frogs, insects, birds, and monkeys. Many of the animals identified by the system are typically difficult to spot in their natural environment, but audio recordings of their calls reveal not only their presence but also their activity patterns.
New forensic method tells the difference between poached and legal ivory
(07/01/2013) Forensic-dating could end a major loophole in the current global ban on ivory, according to a new paper in the Proceedings of the National Academy of Sciences (PNAS). Scientists have developed a method to determine the age of ivory, allowing traders to tell the difference between ivory taken before the ban in 1989, which is still legal, and recently-poached ivory.
Peru opens deforestation data to the public, shows drop in Amazon forest clearing
(06/13/2013) Peru has made its comprehensive deforestation data available to the public.
NASA: Deforestation jumps in Malaysia
(06/10/2013) Deforestation jumped during the first three months of 2013 in Malaysia, Nepal and Mexico, according to a forest tracking tool developed by a team of NASA researchers.
Difference within common species may predict the presence of rare animals
(06/05/2013) When deciding whether or not to clear a patch of rainforest land for development, scientists are often called in to quantify how many different species exist there. But determining the number of rare and threatened species living in a section of jungle isn't easy. If they are very rare, the individual members of the species will be hard to find; if the area being surveyed is along a steep slope it may be difficult to access the area; if there are lots of species to identify, you might need to hire a dream team of biologists—each specialized within a different area of biodiversity—and that can get expensive. However a new study in the Proceedings of the Royal Society Journal by an international group of scientists suggests a more cost-effective and efficient way to rapidly assess local biodiversity.
Data from NASA's Landsat 8 now freely available
(06/02/2013) Data from NAA's Landsat 8 is now freely available, enabling researchers and the general public to access images captured by the satellite within twelve hours of reception. Landsat 8 launched this February and has been capturing images since April. The satellite orbits Earth every 99 minutes and captures images of every point on the planet every 16 days, beaming 400 high resolution images to ground stations every 24 hours.
Could the Tasmanian tiger be hiding out in New Guinea?
(05/20/2013) Many people still believe the Tasmanian tiger (Thylacinus cynocephalus) survives in the wilds of Tasmania, even though the species was declared extinct over eighty years ago. Sightings and reports of the elusive carnivorous marsupial, which was the top predator on the island, pop-up almost as frequently as those of Bigfoot in North America, but to date no definitive evidence has emerged of its survival. Yet, a noted cryptozoologist (one who searches for hidden animals), Dr. Karl Shuker, wrote recently that tiger hunters should perhaps turn their attention to a different island: New Guinea.
Researchers develop highest-resolution global forest cover dataset to date
(05/17/2013) Researchers at the University of Maryland have developed a 30-meter resolution forest cover data set that could boost efforts to track deforestation and forest degradation.
Google Time-lapse offers view of Earth over 3 decades
(05/10/2013) Google has released a series of time-lapse images showing global change between 1984 and 2012. The images are sourced from NASA's Landsat mission, a series of Earth-observation satellites that have orbited the planet since 1972, providing scientists, policymakers, and the general public with a wealth of data and imagery used for a wide range of applications.
Brazil's satellite monitoring reduced Amazon deforestation by 60,000 sq km in 5 years
(05/08/2013) Brazil's advanced satellite monitoring system, coupled with increased law enforcement, was responsible for nearly 60 percent of the 101,000 square kilometer-drop in deforestation observed between 2007 and 2011, argues a new study published an international think tank.
Frankenfish or scientific marvel?: giant GM salmon await U.S. approval
(05/07/2013) It is hard to think of a more unlikely setting for genetic experimentation or for raising salmon: a rundown shed at a secretive location in the Panamanian rainforest miles inland and 1,500m above sea level. But the facility, which is owned by an American company AquaBounty Technologies, stands on the verge of delivering the first genetically modified food animal—a fast-growing salmon—to supermarkets and dinner tables.
Bat's tongue could inspire miniature surgical robot design
(05/06/2013) Nectar-feeding bats shift the shape of their tongue to slurp up sugar from flowers upon which they feed, finds a new study published in the Proceedings of the National Academy of Sciences.
A new tool against illegal logging: tree DNA technology goes mainstream
(04/22/2013) Modern DNA technology offers a unique opportunity: you could pinpoint the origin of your table at home and track down if the trees it was made from were illegally obtained. Each wooden piece of furniture comes with a hidden natural barcode that can tell its story from a sapling in a forest all the way to your living room.
Entire planet will soon have rapid deforestation detection system
(04/09/2013) World Resources Institute (WRI) today previewed a long-awaited tool that could revolutionize global forest monitoring, reports the UN Forum on Forests, which is meeting this week in Istanbul, Turkey.
Conservation gets boost from new Landsat satellite
(04/03/2013) Efforts to monitor the world's forests and other ecosystems got a big boost in February with the launch of Landsat 8, NASA's newest earth observation satellite, which augments the crippled Landsat 7 currently orbiting Earth (technically Landsat 8 is still named the Landsat Data Continuity Mission (LDCM) and will remain so until May when the USGS turns control of the satellite over to NASA). Landsat 8/LDCM is the most advanced Earth observation satellite to date. It is the eighth Landsat since the initial launch in 1972.
Scientists a step closer toward creating biofuels directly from atmospheric CO2
(03/29/2013) Researchers have taken a step closer to using atmospheric carbon dioxide as a biofuel, potentially helping mitigate climate change while at the same time meeting rising energy demand, according to a study published in the Proceedings of the National Academy of Sciences.
Energy efficiency gains failing to keep pace with Internet's growth
(03/29/2013) Energy efficiency is failing to keep pace with the Internet's rapid rate of expansion, meaning that web use is consuming an increasing amount of energy, warns a new perspective published in the journal Science.
Male lions require dense vegetation for successful ambush hunting
(03/20/2013) For a long time male lions were derided as the lazy ones in the pride, depending on females for the bulk of hunting and not pulling their weight. Much of this was based on field observations—female lions hunt cooperatively, often in open savannah, and therefore are easier to track at night. But new research in Animal Behaviour is showing that males are adroit hunters in their own right, except prickly males hunt alone and use dense vegetation as cover; instead of social hunting in open savannah, they depend on ambushing unsuspecting prey.
Scientists successfully freeze Barbary sheep embryos for conservation purposes
(03/18/2013) The Barbary sheep (Ammotragus lervia), or aoudad, is a goat-antelope found in northern Africa. It is currently listed as Vulnerable by the IUCN Red List, with populations imperiled by hunting, habitat loss, and competition with livestock. Still little is known about its remaining population, prompting scientists in Mexico to test possible assisted reproduction of captive individuals.
Deforestation in key Madagascar park accelerated after 2009 coup d'etat, finds satellite analysis
(03/18/2013) Deforestation and forest disturbance in Madagascar's largest national park increased significantly less than a year after a coup displaced the country's democratically-elected president in 2009, finds a new study that analyzed forest cover in Masoala National Park.
A promising initiative to address deforestation in Brazil at the local level
(03/05/2013) The history of the Brazilian Amazon has long been marked by deforestation and degradation. Until recently the situation has been considered out of control. Then, in 2004, the Brazilian government launched an ambitious program to combat deforestation. Public pressure—both national and international—was one of the reasons that motivated the government to act. Another reason was that in 2004, deforestation contributed to more than 55 percent of Brazil’s total greenhouse gas emissions, making Brazil the fourth-largest greenhouse gas emitter in the world.
Frogs radio-tracked for first time in Madagascar
(03/01/2013) Researchers have radio-tracked frogs for the first time in Madagascar. Attaching tiny radio transmitters weighing 0.3-0.35 grams (1/100 of an ounce) to 36 rainbow frogs (Scaphiophryne gottlebei), the research team tracked the movement of the colorful frogs through rugged canyons in Madagascar's Isalo Massif. They found that the frogs have a short breeding period that occurs after the first intense rainfall at the start of the rainy season.
Good news about climate change? Evolving technology could make cleaning the air more profitable than fouling it
(02/26/2013) In the wake of the hottest and driest summer in memory throughout much of North America, and Super-storm Sandy that flooded cities and ravaged large swaths of the Mid-Atlantic coast, many now recognize that the climate change isn’t just real, but that it is already at our doorstep. As this realization continues to sink in, the political will may ripen to take more aggressive action to put a brake CO2 emissions. Already, President Obama, who had remained mostly silent on the issue during his reelection campaign, has made it clear that tackling climate change will be among his top second-term priorities. But the fact remains that even if the entire world switched magically to 100 percent solar and other non-polluting power sources tomorrow, it’s too late to roll back some of the impacts of climate change.
Featured video: Saving the Amazon through maps
(02/20/2013) In a new video ethnobotanist, Mark Plotkin, talks about recent—and historical—efforts to preserve the Amazon rainforest through map-making and technology. Today scientists like Plotkin are teaching indigenous people how to digitally map their territory to win land rights over the forest they've used for centuries.
NASA data registers strong deforestation signals in Sumatra, Borneo, Brazil, Gabon
(01/29/2013) NASA satellites picked up signals of extensive potential deforestation in Sumatra, Borneo, Central Africa, the Brazilian and Peruvian Amazon, the Chocó in Colombia and Ecuador, and the Chaco region of Paraguay between October 1 and December 31, 2012, according to the latest update on Mongabay.com's Global Forest Disturbance Alert System (GloF-DAS).
Illegally logged trees to start calling for help
(01/24/2013) Illegal loggers beware: trees will soon be calling—literally—for backup. The Brazilian government has begun fixing trees with a wireless device, known as Invisible Tracck, which will allow trees to contact authorities after being felled and moved.
Bloodsucking flies help scientists identify rare, hard-to-find mammals
(01/16/2013) Last year scientists released a study that is likely to revolutionize how conservationists track elusive species. Researchers extracted the recently sucked blood of terrestrial leeches in Vietnam's remote Annamite Mountains and looked at the DNA of what they'd been feeding on: remarkably researchers were able to identify a number of endangered and rarely-seen mammals. In fact two of the species gleaned from these blood-meals had been discovered by scientists as late as the 1990s. In the past, trying to find rare and shy jungle animals required many man hours and a lot of funding. While the increasing use of remote camera traps has allowed scientists to expand their search, DNA sampling from leeches could be the next big step in simplifying (and cheapening) the quest for tracking the world's mammals.
