Photos: The Glamorous New Species of Papua New Guinea

The island nation of <a href="http://www.state.gov/r/pa/ei/bgn/2797.htm" target="_blank">Papua New Guinea</a> is one of those places where biologists go to make extraordinary discoveries. During recent rainforest expeditions coordinated by <a href="http://www.conservation.org/Pages/default.aspx" target="_blank">Conservation International</a>, researchers turned up about 200 new species.  In a press release, the group explained its goals: "The searches were conducted as part of CI’s global efforts to document the biodiversity of poorly known but species-rich environments, and raise their profile to assist local communities establish conservation priorities for future development."<br /><br />This bright green frog is believed to be new to science. It lives 100 feet up in the forest canopy, and taunted curious researchers down below with its loud, guttural croaks all night long. They finally caught their first glimpse of a handsome male by sending a local climber up to the treetops.This tube-nosed fruit bat is not entirely new to science--but we had to include him because he may be the most fetching creature on the planet. <br /><br />Researchers say this species has been previously seen but is still undescribedin the scientific literature; it belongs to the genus <em>Nyctimene</em> but doesn't have an official species name yet. It lives in the tropical forests of Papua New Guinea's Muller Range mountains, and probably plays an important role in dispersing plant seeds. <br />Researchers found a bonanza of <a href="http://en.wikipedia.org/wiki/Tettigoniidae" target="_blank">katydids</a> (a group of insects related to crickets and grasshoppers) in Papua New Guinea's forests--they've identified at least 20 new species. As these insects live in the rainforest canopy, they're difficult to collect and virtually unstudied. This pink-eyed Caedicia is thought to feed on tree flowers. <br />This newly discovered spider was spotted in the Nakanai Mountains on the island of <a href="http://en.wikipedia.org/wiki/New_britain" target="_blank">New Britain</a>. It's one of four new species found from the genus <em>Anelosimus</em>.This feather-tailed possum has also been spied before by eagle-eyed biologists, but it has yet to be described in the scientific literature. The possum was found again on a recent expedition by happy accident. It was attracted to a light-trap put up by entomologists to catch nocturnal insects; the researchers suggest it may have been trying to catch and eat moths. It was found at an elevation of about 5,200 feet in the Muller Range mountains.Another colorful new frog was found in the lush foliage along small rainforest streams in the Muller Range mountains. Researchers say it was suprisingly difficult to find this striking member of the <em>Litoria genimaculata</em> group; they had the most luck tracking down specimens when they followed the soft ticking sound made my mating males. <br />Here's a critter that knows how to defend itself. When threatened, this newly discovered katydid extends its hind legs straight into the air, and tries to jab any attacker with the spiny limbs.

Drop in Illegal Logging Left 42 Million Acres of Forest Standing Tall

loggingImagine enough forest to cover the state of Florida. According to a recent report (pdf), a downturn in illegal logging has protected that amount of forest land–some 42 million acres–over the past decade.

The decrease is a good start, London think tank Chatam House authors say, but there is still more work to do.

“We’re a quarter of the way there,” said Sam Lawson, one of the report’s authors. He expressed the hope that newer regulations–such as a European law passed last week that will ban the import of illegal timber by 2012–would cut the amount of illegal logging even further. [AP]

During the last decade, the report says, Cameroon, the Brazilian Amazon, and Indonesia have decreased logging between 50 and 75 percent. Meanwhile, the seven studied consumer and processing countries have decreased illegally harvested wood imports by 30 percent.

Among those importing countries is the United States, which in 2008 became the first country to ban all imports of illegally logged plants and plant products, including furniture and paper. Europe’s ban, passed earlier this month, will go into effect in 2012.

Borneo’s Wild New Species: A “Ninja Slug,” the World’s Longest Bug, & More

NEXT>

A flying frog that changes colors, a stick insect that’s a foot and a half long, and a “ninja slug” that shoots “love darts.” These are among the 120 new species discovered or described over the past three years on the lush island of Borneo–the Southeast Asia island divided between Malaysia, Indonesia, and Brunei.

On Earth Day, the conservation group WWF released a report on some of the recent discoveries in a 54-million-acre nature preserve known as the Heart of Borneo. WWF ecologist Adam Tomasek says that on an average, three new species were found every month.

Teenage Mutant Ninja Slugs?

borneo-ninja-slug_19337_600

This colorful green and yellow slug species, named Ibycus rachelae, was discovered atop high mountains in the Malaysian section of Borneo. The slug has a tail three times the length of its head, and it wraps the tail around itself when it is resting. From the Ariophantidae family, this unusual species makes use of so-called ‘love darts’ in courtship. Made of calcium carbonate, the love dart is harpoon-like which pierces and injects a hormone into a mate, and may play a role in increasing the chances of reproduction [Guardian].

Massive Hydroelectric Dam in the Amazon Will Go Ahead

Xingu_RiverBrazil’s controversial plan to build the third-largest dam in the world right in Amazon rainforest got the go-ahead from the environmental ministry this week. The ministers approved the permits for the dam project, and now companies can begin to bid on the building rights. But whoever wins will have to pay out at least some money to protect the local environment.

The 11,000-megawatt Belo Monte dam is part of Brazil’s largest concerted development plan for the Amazon since the country’s military government cut highways through the rainforest to settle the vast region during its two-decade reign starting in 1964 [Reuters]. Nearly all huge dam projects raise environmental concerns because they flood vast areas and can change ecosystems so drastically. But the Belo Monte, to be built on the Xingu River, has the additional trouble of being in one of the most important habitats in world and near to populations of indigenous peoples. The Xingu is a tributary of the Amazon River.

Syncopated Rhythm Makes Orangutans Masterful Swingers

OrangutanIt may seem as though orangutans’ 180-pound bodies would be unwieldy when it comes to swinging from delicate tree branches in the rainforests of Indonesia and Malaysia. But the animals have figured out a variety of ways to navigate treetops, allowing them to avoid a potentially deadly fall, according to a study published in the Proceedings of the National Academy of Sciences.

When scientists observed wild orangutans in the Sumatran rainforest, they found that the animals traversed the delicate branches by moving their bodies with a rhythm that counters the vibrations of the trees. At the highest treetops in the forest, tree branches are thin and begin to wobble as animals climb on them, much as a suspension footbridge vibrates as people walk over it. Too much vibration and an orangutan can be thrown off altogether. From high in the trees, such a fall would be deadly [Time]. But because orangutans move with an irregular beat, they avoid compounding the already-shaking branches with the motion of their own bodies. Also increasing their stability, the animals also have the habit of grasping more than one branch at once–in fact, nearly one-third of the time, orangutans held on to more than four branches simultaneously.

Next Year’s Nike: Amazon-Friendly Air Jordans

cattleNike, the world’s largest maker of athletic shoes, said yesterday it is adopting a policy that prohibits the use of leather from cattle raised in Brazil’s Amazon rainforest. The announcement came after a Greenpeace statement released about a month ago citing cattle farming as the main driver as deforestation in the region, and a significant contributor to global warming, as ranchers clear vast stretches of land for grazing.

The company established a formal Amazon leather policy and will give its leather suppliers until the first day of next July to “create an ongoing, traceable and transparent system to provide credible assurances that leather used for Nike products is from cattle raised outside of the Amazon Biome” [AP].

Chopping Down the Amazon Causes a Short-Term Boom, Long-Term Bust

Amazon deforestationLeaving the rainforest of the Amazon standing has obvious benefits to the environment, as the living forests absorb and store carbon dioxide that would otherwise contribute to global warming. But cutting down the forests has been assumed to be the only route to economic development for the local people, as it provides work in the timber industry and then clears the way for farming and cattle raising. Now, a new study has found that deforestation brings only short-term and temporary economic benefits, in what researchers call a boom-and-bust cycle.

The researchers say the boom is probably due to a number of factors, including better roads and therefore better access to healthcare and schools. For a short while, the community benefits from the natural resources of the forest, and makes money off the timber and the farms that are set up in the cleared lands. But the soil is rapidly degraded making farming and cattle ranching unsustainable. “A lot of that land ends up being abandoned” [New Scientist], says study coauthor Robert Ewers.

Saving the Rainforest Could Make Economic Sense

orangutan borneoA landowner in Indonesia may soon find it more profitable to sell carbon credits from untouched forest than to clear the land for agriculture, according to new research. As a case study, the researchers looked at 8.2 million acres that are slated to become plantations in Kalimantan, the Indonesian region of the island of Borneo. The researchers found that paying to conserve the forest was more valuable than plantations as long as poorer nations could earn between $10 and $33 for each tonne of CO2 saved. Currently a credit representing a tonne of CO2 sells for about $20 in the European Union, which has the world’s largest greenhouse gas trading system [The New York Times].

Since forests act like sponges for carbon dioxide, the principal greenhouse gas driving global warming, they can play a role in carbon credit markets that are used in international climate treaties. Industries that can’t cut their emissions enough pay landowners to leave their forests standing, so the trees can suck up carbon and offset the industrial emissions. What’s more, researchers say that such systems could also be a roundabout way to protect endangered species. The 800 proposed plantations that were studied contain 40 of the region’s 46 threatened mammals including orangutans and pygmy elephants [AP].

Happy News: New Population of Endangered Orangutans Found in Borneo

orangutanIn the remote limestone mountains on the eastern edge of the island of Borneo, a large population of orangutans has been living quite happily, far from human settlements and untouched by the trouble that we humans can bring. Based on a rumor of the primate outpost researchers traveled for days through the mountains, and eventually discovered 219 orangutan nests in the forest, which they say could indicate that as many as 2,000 orangutans live there.

With only about 50,000 orangutans remaining in the wild, conservationists say it’s a rare piece of good news for the endangered species. “We rarely have something positive to report in the conservation world. Most of the stories are about declining population or animals dying. It’s all pretty negative,” said Erik Meijaard, a senior ecologist with the U.S.-based Nature Conservancy. “So to find a substantial population of potentially several hundred to several thousand animals is very exciting” [CNN].

Tigers and Humans Tangle in Sumatra; Both Sides Lose

tiger.jpgA growing conflict between Indonesian loggers and the critically endangered Sumatran tiger has incurred a death toll on both sides, with little solution in sight. Environmentalists say that Asian Pulp and Paper (APP), one of the largest paper companies in the world, has destroyed much of the island of Sumatra’s rainforest. The activists argue that the tigers, whose wild population is thought to hover at around 400 but could be as low as 250, have been left without a natural habitat and have increasingly regarded humans for food. Eyes on the Forest, a coalition of 25 environmental organizations, has released a report to back up the allegation.

By overlaying the locations of [human-tiger] conflicts with government maps of pulpwood plantation concessions, Eyes on the Forest found a direct correlation between tiger conflict and the unsustainable forest practices of APP, its holding company Sinar Mas Group, and other associated companies that supply pulpwood to APP’s mills [Wildlife Extra], with 60 percent of the total 245 human-tiger encounters having taken place on land associated with those companies.

2005 Drought Turned the Amazon Into a Carbon-Spewing Factory

Amazon leafTropical rainforests are often considered one of the world’s greatest protections against global warming, as the lush forests can absorb huge amounts of carbon dioxide, the main greenhouse gas behind climate change. But shifting weather patterns can transform the rainforest from an ally to a hindrance: According to an international study, a 2005 drought in the Amazon rainforest killed trees and released more greenhouse gas than the annual emissions of Europe and Japan [Reuters].

Researchers say that the 2005 drought slowed the growth of trees, thereby slowing their absorption of carbon dioxide, and also killed off trees, which emitted carbon dioxide as they rotted. Researchers say that if global warming brings more dramatic weather patterns and dryer conditions to the Amazon, as some climate models predict, the rainforest could even accelerate global warming. Says lead researcher Oliver Phillips: “For years, the Amazon forest has been helping to slow down climate change. But relying on this subsidy from nature is extremely dangerous…. We cannot take this carbon sink for granted” [CBC].

Super-Sized Snake Ate Crocodiles for Breakfast


giant snakeIn a coal mine in Colombia, researchers have unearthed the fossilized remains of the mother of all snakes, a nightmarish tropical behemoth as long as a school bus and as heavy as a Volkswagen Beetle [Los Angeles Times]. The new species, named Titanoboa cerrejonensis, is related to modern boa constrictors, but those descendants are puny in comparison to their primordial ancestor. Titanoboa grew up to 43 feet long and weighed about 2,500 pounds, researchers say, making it the largest snake on record.

The researchers used a known mathematical relationship between the size of vertebrae and the length of the body in living snakes to estimate the size of the ancient animal [BBC News]. Researchers say the ancient boa lived in the wet, tropical rainforest about 60 million years ago, and may have dined on giant turtles and primitive crocodiles–the fossilized remains of those animals were found near the snake fossils. But the extinct snake isn’t just interesting because of its superlative size; researchers also used it to investigate the Earth’s climate in the snake’s day.

The Latest Threat to the Amazon Rainforest: Hackers


Amazon loggingTrees continue to fall due to illegal logging operations in the the Amazon rainforest, and Brazil’s environmental officials have discovered that those logging companies hired not just lumberjacks to get the job done, but also hackers. The hackers went to work in the Brazilian state of Pará, where the local government has launched an online system for issuing permits to logging companies. The system tracks their total output and simply refuses to issues more permits, which are checked when the wood is hauled out in trucks [Ars Technica].

But instead of abiding by the limits on the amount of timber they could haul out of the rainforest, more than 107 companies allegedly hired hackers to access the government records and increase their timber allocations. Andre Muggiati, a Greenpeace official in Brazil, said that “by hacking into the permit system, these companies have made their timber shipments appear legal and compliant with the forest management plans” [Wired News]. The Brazilian government has already arrested more than 30 people involved in the scandal.

As Amazon Rainforest Destruction Continues, Brazil Pledges Drastic Action


Amazon deforestationIn the wake of a distressing report about accelerating deforestation in the Amazon rainforest, the Brazilian government has vowed to reduce the rate of land-clearing by 70 percent over the next decade. The government was called upon to take drastic steps after a report declared that deforestation increased this year for the first time since 2004 as surging prices for cattle and soybeans led ranchers to seek farm land in the forest. The world’s largest rainforest lost 11,968 square kilometers (4,600 square miles), an area about 10 times as large as New York City, in the 12 months through July 2008 [Bloomberg].

Tasso Azevedo, head of the Brazilian government’s forestry service said: “We can now adopt targets because we now have the instruments to implement them.” He was referring to a new Amazon fund, where foreign nations are being encouraged by Brazil to contribute financially to the conservation of the vast Amazon region [BBC News]. Norway has already agreed to contribute $1 billion to the fund over the next seven years on the condition that deforestation rates continue to drop during that time; however, Norway’s pledge is hoped to be just the beginning. The Brazilian government wants to raise $21 billion in donations to finance conservation and sustainable development projects, arguing that since the whole world receives climate benefits from an intact Amazon rainforest, the whole world should subsidize it.

Deep in the Jungle, A Fungus Pumps Out Diesel From Wood

fungusA newly discovered tree fungus could be on its way to the gas station. The fungus, Gliocladium roseum, is able to turn plant matter into gaseous hydrocarbons that are almost chemically identical to diesel fuel. “This is the only organism that has ever been shown to produce such an important combination of fuel substances,” said researcher Gary Strobel from Montana State University. “The fungus can even make these diesel compounds from cellulose, which would make it a better source of biofuel than anything we use at the moment” [LiveScience].

The fungus grows inside trees in the rainforests of Patagonia, in the southern part of Argentina and Chile. After discovering the new fungus wedged between cells in a stem from an Ulmo tree (Eucryphia cordifolia), Strobel and colleagues cultured the organism, collected the gaseous compounds it produced, and ran the compounds through a mass spectrometer to identify them. When he saw the printout, Strobel says, “every hair on my body stood up.” The list included octane, 1-octene, heptane, 2-methyl, and hexadecane–all common components of diesel fuels [ScienceNOW]. The gaseous compound, dubbed “myco-diesel,” is thought to be used by G. roseum to poison other fungi.
