Scientists Sequence DNA Of Woolly Mammoth (December 21, 2005) — A team of experts in ancient DNA from McMaster University (Canada) and genome researchers from Penn State University (USA) have obtained the first genomic sequences from a woolly mammoth, a mammal that roamed grassy plains of the Northern Hemisphere until it became extinct about 10,000 years ago. The project also involved paleontologists from the American Museum of Natural History and researchers from Russia, the United Kingdom, France, and Germany. > full story
UC Santa Barbara Researcher Tapped By Europeans For Design Of Instrument To Test Soil On Mars (December 14, 2005) — The European Space Agency (ESA) is supporting a new program that will include development of an instrument for testing deep soil samples on Mars in a European mission called ExoMars. A researcher at the University of California, Santa Barbara will direct the development of the instrument. > full story
New Study Pinpoints Epicenters Of Earth's Imminent Extinctions (December 13, 2005) — Safeguarding 595 sites around the world would help stave off an imminent global extinction crisis, according to new research published today in the Proceedings of the National Academy of Sciences. Conducted by scientists working with the 52 member organizations of the Alliance for Zero Extinction, the study identifies 794 species threatened with imminent extinction, each of which is in need of urgent conservation action at a single remaining site on Earth. > full story
Russian River Coho Recovery Project Seeing First Hopeful Signs Of Success (December 8, 2005) — Surveys of three streams in the Russian River watershed show the first encouraging signs that a ground-breaking recovery effort is making headway rescuing coho salmon from the brink of extinction in part of its historic California range. > full story
Why The Amazon Rainforest Is So Rich In Species (December 5, 2005) — Tropical areas of south and central America such as the Amazon rainforest are home to some 7,500 species of butterfly compared with only around 65 species in Britain. UCL scientists have ruled out the common theory that attributed this richness of wildlife to climate change, in a paper published on 7th December by the journal Proceedings of the Royal Society B (Biological Sciences). > full story
No Safe Ground For Life To Stand On During World's Largest Mass Extinction (December 2, 2005) — The world's largest mass extinction was probably caused by poisonous volcanic gas, according to research published today. > full story
Removing Egg From Nest May Help Save Endangered Whooping Crane (November 24, 2005) — Removing an egg from the endangered whooping crane's nest increases the species chances of survival despite governmental concerns about tampering with nature, says a University of Alberta scientist. > full story
Gene Controls Whether Fear Is A Factor (November 18, 2005) — In the Nov. 18 issue of Cell, researchers report the discovery of a gene that controls the ability to react with appropriate fear to impending danger. As a result, mice lacking the gene stathmin become daredevils of a sort, the researchers report. The basic findings may have general implications for the study of anxiety disorders and potential anti-anxiety drugs, according to researchers. > full story
Envisat Radar Surveillance Protects Endangered Prehistoric Fish (November 17, 2005) — A satellite surveillance zone within the southern Indian Ocean is helping protect the endangered Patagonian toothfish from pirate fishing vessels. Perched between Africa, India, Australia and Antarctica, the windswept French territory of the Kerguelen Islands is one of the remotest places on Earth. Even so, fishing vessels are lured there by the prospect of catching one valuable species found in its surrounding waters – the Patagonian toothfish, also known as Chilean sea bass, or else 'white gold' for the high prices it commands on the black market. > full story
Abalones Along Pacific Coast May Owe Their Huge, Dinner-plate Size To Sea Otters (November 15, 2005) — California sea otters are maligned for their ruthless pursuit of large abalones prized by divers. But a new study suggests that otters are partly responsible for the size of these abalones, some a foot across. UC Berkeley's David Lindberg and James Estes of USGS speculate that otters keep kelp grazers down so that kelp have not developed toxic chemical defenses. This leaves plenty of tasty food for abalones to gorge on in their rock crevices. > full story
Endangered California Condors: Let Them Eat Seals (November 14, 2005) — A team of scientists is proposing that endangered California condors raised in captivity be released near seal and sea lion rookeries so that the birds can once again feast on the carcasses of marine mammals as their ancestors did centuries ago. > full story
Lack Of Sex Could Be A Signpost To Extinction, Claim Researchers (October 29, 2005) — Researchers from Imperial College London believe that when species become asexual they could be on their way to extinction. The research, published in PLoS Pathogens, looks at the genetic structure of Penicillium marneffei, an asexual fungus. The researchers found that although P. marneffei spores were able to spread over large distances on currents of air, they were not able to 'invade' the new environments in which they landed. > full story
