Despite their reputation for deadly attacks on humans and pets, alligators are wiggling their way toward a new role as potential lifesavers in medicine, biochemists in Louisiana reported today at the 235th national meeting of the American Chemical Society.

Since European settlement two centuries ago, Australia has lost almost a third of its unique mammal species.

Throughout the centuries, widely varying human attitudes toward wolves have been highly-charged and often colored by fear and misunderstanding. As a result, the Gray Wolf has been extirpated in much of Europe and the U.S. Historically, people have tended to view wolves as threats to livestock and human well being, believing that they represent a threat to the notions of civilization and dominance of nature in general.

The first ever study of antibiotic-resistant bacteria in free-living American bison finds resistance rates, while relatively low, are still higher than expected. The researchers from Kansas State University report their findings in the March 2008 issue of the journal Applied and Environmental Microbiology.

Chimpanzees make judgments about the actions and dispositions of strangers by observing others’ behavior and interactions in different situations. Specifically, chimpanzees show an ability to recognize certain behavioral traits and make assumptions about the presence or absence of these traits in strangers in similar situations thereafter.

Hikers and campers venturing into bear country this spring may be safer armed with 8-ounce cans of bear pepper spray than with guns, according to a new study led by a Brigham Young University bear biologist.

In an investigative report published today by Eyes on the Forest, evidence shows that a new logging road in Riau Province -- strongly indicated as illegally built by companies connected to Asia Pulp & Paper (APP) -- is cutting into the heart of Sumatra’s largest contiguous peatland forest, a rare hydrological ecosystem that acts as one of the planet’s biggest carbon stores.

They are separated by a vast ocean and by millions of years, but tiny prehistoric bones found on an Australian farm have been directly linked to a strange and secretive little animal that lives today in the southern rainforests of South America.

The rate at which new species are formed in a group of closely related animals decreases as the total number of different species in that group goes up, according to new research published in PLoS Biology.

The 2008 giant panda mating season began Tuesday, March 18, at the Smithsonian's National Zoo. Female Mei Xiang (may-SHONG) and male Tian Tian (tee-YEN tee-YEN) attempted to mate throughout the day Tuesday.

In a study of New Zealand’s “living dinosaur” the tuatara, evolutionary biologist, and ancient DNA expert, Professor David Lambert and his team from the Allan Wilson Centre for Molecular Ecology and Evolution recovered DNA sequences from the bones of ancient tuatara, which are up to 8000 years old.

Brown bears from the Iberian Peninsula are not as genetically different from other brown bears in Europe as was previously thought. An international study being published this week in Proceedings of the National Academy of Sciences, PNAS, shows that, on the contrary, the Spanish bear was only recently isolated from other European strains.
