Little-known flatback sea turtle receives extra attention at symposium in Australia
(02/17/2009) Beginning today in Brisbane, Australia, the 29th annual Symposium on Sea Turtle Biology and Conservation will feature the flatback sea turtle, native to Australia and probably the least-studied of the marine turtle species. For a hundred years biologists debated as to how closely the flatback marine turtle was related to the green sea turtle. Several unique attributes of the flatback came to the forefront. The name ‘flatback’ describes the turtle’s distinct flattened carapace. The species also lays the largest eggs of any sea turtles, proportional to their size. However, perhaps most distinctly the flatback is the only marine turtle to call one nation home. The flatback forages, mates, and lays eggs along Australia’s coats; its penchant for swimming, rather than riding oceanic currents, keeps it from migrating across oceans as other turtle do.
Photos: 13,000 species found in Arctic, Antarctic Oceans
(02/16/2009) A marine census has documented more than 13,000 species in the Arctic and Antarctic Oceans, including several hundred that may be new to science. Conducted over a two-year period under often perilous conditions — including monster waves and dangerous polar bears — the series of 18 surveys turned up a wealth of information on the diversity, distribution and abundance of marine life. The research will also help establish a baseline for measure changes in polar ecosystems.
Burning rainforests, melting tundra could accelerate global warming well beyond current projections

Beef consumption fuels rainforest destruction
(02/16/2009) Nearly 80 percent of deforestation in the Brazilian Amazon results from cattle ranching, according to a new report by Greenpeace. The finding confirms what Amazon researchers have long known – that Brazil's rise to become the world's largest exporter of beef has come at the expense of Earth's biggest rainforest. More than 38,600 square miles has been cleared for pasture since 1996, bringing the total area occupied by cattle ranches in the Brazilian Amazon to 214,000 square miles, an area larger than France. The legal Amazon, an region consisting of rainforests and a biologically-rich grassland known as cerrado, is now home to more than 80 million head of cattle. For comparison, the entire U.S. herd was 96 million in 2008.
Pricing emissions from farming, logging could shift land use towards conservation
(02/15/2009) Putting a price tag on carbon dioxide emissions resulting from various land use practices could dramatically change the way that land is used, including reducing deforestation and limiting agricultural expansion on carbon-rich lands, said a researcher presenting at the annual meeting of the American Association for the Advancement of Science.
Mass media ‘screwing up’ global warming reporting says renowned climatologist
(02/15/2009) Stanford scientist and climate-specialist Stephen Schneider has called out media organizations for the quality of their reporting on climate change and other scientific issues.

Fishermen - not whales as claimed by Japan - are the cause of fisheries depletion
(02/12/2009) Fishermen calling for a resumption of whaling to restore commercial fish stocks are taking the wrong approach, argue researchers writing in the journal Science. Analyzing data on fish catch and whale abundance off the coast of northwestern Africa and the Caribbean, Leah R. Gerber and colleagues show that fishermen remove far more fish than whales consume, undermining the agreement by whaling nations that whales are driving depletion of fisheries.
Fit with tiny backpacks, songbirds reveal speed of migration at 311 miles a day
(02/12/2009) Using extra tiny geo-locator backpacks, researchers have tracked songbirds’ seasonal migrations for the first time, according to research published in Science .

As sea ice retreats, swathe of Arctic closed to fishing
(02/06/2009) The North Pacific Fishery Management Council (NPFMC) voted unanimously to close off more than 150,000 square nautical miles of the Arctic sea to commercial fishing. The decision, welcomed by an array of environmentalists and industry groups, is a preventative measure to protect fisheries that have become more accessible as a result of declining sea ice in the Arctic. It is the first time that the federal government has closed a fishery due to climate change instead of over-fishing, says supporters of the ban.

Butterfly tricks ants by mimicking their queen’s vocalizations
(02/05/2009) With cohesive hierarchical societies and a number of communication techniques, ants have been able to conquer a wide variety of ecosystems with great success. However, according to a recent paper in Science ants’ highly structured society at times comes with a price. A number of insects have evolved means to covertly infiltrate the ants’ society and live off their work and bounty by closely mimicking various ant communication methods. While scientists believe that these parasitical insects largely mimic ant communications like chemical exchange and physical contact—such as touching antennae—the study, however, discovered a butterfly which succeeds in infiltrating the highest echelons of ant society by vocalizing like a queen.

Monstrous prehistoric snake provides glimpse of warmer tropical forests
(02/04/2009) On Wednesday scientists announced the discovery of the world’s largest snake, a prehistoric beast which preyed on giant turtles and crocodile-like reptiles in South America after the demise of the dinosaurs. As amazing as the discovery is, its greatest importance may be the clues it provides conservationists about the future of tropical forests under various global warming scenarios.
World’s largest snake discovered: prehistoric serpent was twice the size of an anaconda
(02/04/2009) Paleontologists have recently uncovered the world’s largest snake announces a paper in Nature. Measuring an astonishing 42 to 45 feet, the Titanoboa cerrejonensis makes the anaconda look diminutive. In fact the prehistoric serpent even makes once-ridiculous horror movie snakes appear conservative. "Truly enormous snakes really spark people's imagination, but reality has exceeded the fantasies of Hollywood," said Jonathan Bloch, one of the leaders of the party that discovered the prehistoric serpent. "The snake that tried to eat Jennifer Lopez in the movie Anaconda is not as big as the one we found."
12 new species of frogs discovered in India
(02/03/2009) A dozen previously unknown species of frogs have been discovered in the forests of Western Ghats according to a paper published in latest issue of Zoological Journal of Linnean Society, London. The 12 species have been identified following a revision of the Philautus genus and are the result of ten years of field study in Kerala, Tamil Nadu, Karnataka. Goa, Maharashtra, and part of Gujarat, in the Western Ghats. The Western Ghats are considered a global biodiversity hotspot for their species richness and the threats the mountain range faces.
Chocolate has been a delicacy north of Mexico for a thousand years
(02/02/2009) Chocolate, produced from cacao beans, has been a part of American culture for a thousand years according to new paper published in the Proceedings of the National Academy of Sciences. Analyzing chemical residue from jars of native peoples in New Mexico, researchers Patricia Crown and Jeffrey Hurst discovered theobromine, a chemical signature of cacao. The jars have been dated from 1000 to 1125 AD, well over three hundred years before Columbus and the earliest recorded discovery of cacao north of Mexico. The cacao jars are from Pueblo Bonito, an archaeological site in Chaco Canyon, which is located in northwestern New Mexico. Chaco Canyon, once home to 2,000-5,000 inhabitants, was composed of a dense group of pueblos, of which Bonito was the largest. Incorporating 800 rooms, Pueblo Bonito was the center of a number of towns and villages in Chaco Canyon.
Seeking out the world’s rarest and most endangered birds
(02/02/2009) For an evolutionary biologist there is no conservation group whose work is more exciting than EDGE, a program developed by the Zoological Society of London (ZSL). Unique in the conservation world, EDGE chooses the species to focus on based on a combination of their threat of extinction and evolutionary distinctness. Katrina Fellerman, an evolutionary biologist herself and the EDGE birds’ coordinator, describes the organization as one that focuses on species, which “to put it bluntly, if lost, there would be nothing like them left in the world today”. Explaining further Fellerman says “We use evolutionary distinctiveness (ED) as a species-specific measure of the relative evolutionary value of species - it is a way of apportioning conservation value according to a species’ phylogenetic position. Species with few or no close relatives on the ‘tree of life’ have the highest ED scores.”
Amazon scientists awarded 'Nobel Prize' of conservation
(02/01/2009) Thomas Lovejoy of the H. John Heinz III Center for Science, Economics and the Environment and William F.
