 | As western states debate removing the gray wolf from protection under the Endangered Species Act, a new study by the Wildlife Conservation Society cautions that doing so may result in an unintended decline in another species: the pronghorn, a uniquely North American animal that resembles an African antelope. ...> Full Article |
 | Scientists have recently found evidence that rain-making bacteria are widely distributed in the atmosphere. These biological particles could factor heavily into the precipitation cycle, affecting climate, agricultural productivity and even global warming ...> Full Article |
 | Biologists have developed a series of global maps that show where projected habitat loss and climate change are expected to drive the need for future reserves to prevent biodiversity loss. ...> Full Article |
 | Rats use their whiskers in a way that is closely related to the human sense of touch: Just as humans move their fingertips across a surface to perceive shapes and textures, rats twitch their whiskers to achieve the same goal. Now, in a finding that could help further understanding of perception across species, MIT neuroscientists have used high-speed video to reveal rat whiskers in action and show the tiny movements that underlie the rat's perception of its tactile environment. ...> Full Article |
 | Giant bluefin tuna are in trouble, primarily because the powerful muscles that propel their extensive ocean migrations come with an Achilles' heel: They're tasty. ...> Full Article |
 | Some of the smallest plants on the planet may play a vital role in some of the largest questions facing mankind today, according to marine scientists at the University of Portsmouth and the National Oceanography Centre, Southampton (NOCS). ...> Full Article |
 | Scientists find physical and genetic reasons for various juniper species' drought-resistance ...> Full Article |
 | Researchers have known for awhile that little whirlpools of air stirred up by insects' wing motions can help keep these small organisms aloft as they fly slowly or hover, two activities essential for food foraging. But how a weightier organism-a bat-manages to stay aloft during slow flight has remained unclear. ...> Full Article |
 | The Svalbard Global Seed Vault opened today on a remote island in the Arctic Circle, receiving inaugural shipments of 100 million seeds that originated in over 100 countries. With the deposits ranging from unique varieties of major African and Asian food staples such as maize, rice, wheat, cowpea, and sorghum to European and South American varieties of eggplant, lettuce, barley, and potato, the first deposits into the seed vault represent the most comprehensive and diverse collection of food crop seeds being held anywhere in the world. ...> Full Article |
 | Seabird colonies on islands are highly vulnerable to introduced rats, which find the ground-nesting birds to be easy prey. But the ecological impacts of rats on islands extend far beyond seabird nesting colonies, according to a new study by researchers at the University of California, Santa Cruz. ...> Full Article |
 | Study suggests salamanders are "keystone" species ...> Full Article |
 | With the support of the Fund for Creative Research Groups of the National Natural Science Foundation of China (NSFC), researchers from the CAS Institute of Microbiology (IOM) started a 5-million-yuan three-year research project on life in extreme conditions one year ago. Now the studies are making encouraging progress, announced the annual conference of the project held on 21 January in Beijing. ...> Full Article |
 | Scientists have discovered Antarctic krill (Euphausia superba) living and feeding down to depths of 3000 metres in the waters around the Antarctic Peninsula. Until now this shrimp-like crustacean was thought to live only in the upper ocean. The discovery completely changes scientists' understanding of the major food source for fish, squid, penguins, seals and whales. ...> Full Article |
 | The return of the last of three Antarctic marine science research vessels marks the culmination of one of Australia's most ambitious International Polar Year projects, a census of life in the icy Southern Ocean known as the Collaborative East Antarctic Marine Census (CEAMARC). ...> Full Article |
 | Thousands of sick bats have been found in caves in New York state. While bat experts do not know what is causing the bats' demise, telltale signs include weight loss and white fungus around their noses. ...> Full Article |
 | Hunted to near extinction, sea otters are making a steady comeback along the Pacific coast. Their reintroduction, however, is expected to reduce the numbers of several key species of commercially valuable shellfish dramatically, such as sea urchins and geoducks. ...> Full Article |
 | How young migrating birds choose the nesting location of their first breeding season has been something of a mystery in the bird world. But a new study of the American redstart by the University of Maryland and Smithsonian Migratory Bird Center of the National Zoo suggests that the environmental conditions the birds face in their first year may help determine where they breed for the rest of their lives, a factor that could significantly affect the population as climate change makes their winter habitats hotter and drier. ...> Full Article |
 | The process of natural selection can act on human culture as well as on genes, a new study finds. ...> Full Article |
 | They may be considered pests, but beaver can help mitigate the effects of drought, and because of that, their removal from wetlands to accommodate industrial, urban and agricultural demands should be avoided when possible, according to a new University of Alberta study. ...> Full Article |
 | A new study by the Bronx Zoo-based Wildlife Conservation Society found that jack rabbits living in the Greater Yellowstone Ecosystem have apparently hopped into oblivion. The study, which appears in the journal Oryx, also speculates that the disappearance of jack rabbits may be having region-wide impacts on a variety of other prey species and their predators. ...> Full Article |
 | One of the UK's rarest mammals - Bechstein's bat - will be surveyed and monitored under a new three-year project using technology developed by the University of Sussex. ...> Full Article |
 | The Wildlife Conservation Society and the Panthera Foundation announced plans to establish a 5,000 mile-long "genetic corridor" from Bhutan to Burma that would allow tiger populations to roam freely across landscapes. The corridor, first announced at the United Nations on January 30th, would span eight countries and represent the largest block of tiger habitat left on earth. ...> Full Article |
 | A team of scientists has just left the country to explore a very strange lake in Antarctica; it is filled with, essentially, extra-strength laundry detergent. No, the researchers haven't spilled coffee on their lab coats. They are hunting for extremophiles -- tough little creatures that thrive in conditions too extreme for most other living things. ...> Full Article |
 | Fatal shark attacks worldwide dipped to their lowest levels in two decades in 2007 with the sole casualty involving a swimmer vacationing in the South Pacific, according to the latest statistics from the University of Florida. ...> Full Article |
 | The "flying" lemur of Malaysia is the champion of all gliding mammals, able to drop from the forest canopy, glide more than the length of two football fields, execute 90-degree turns and then alight gently on a tree trunk. ...> Full Article |

 | For several years, scientists have been working to determine why so many male smallmouth bass in the Potomac River basin have immature female egg cells in their testes - a form of intersex. They are closer to finding an answer. ...> Full Article |
