    tasmanian devils

    Tasmanian devils (Sarcophilus harrisii) disappeared from mainland Australia centuries ago, probably not long after humans first brought dingoes to the continent. A new plan could bring the infamous, snarling predators back from the island of Tasmania to Oz. That would not only benefit the devils, which are dying out due to a communicable cancer, but [...]

    A massive project to assess the health of wildlife in Bangladesh has confirmed conservationists’ longstanding suspicions that sloth bears no longer exist in that country. Sloth bears (Melursus ursinus) could once be found throughout India, Nepal, Bhutan and Bangladesh. (A separate subspecies lives on the island nation of Sri Lanka.) Overhunting during the British colonial [...]

    The squirrels gliding amid the mountains east of Los Angeles have been, for the most part, flying under the scientific radar. There has never been a single scientific paper published specifically about the San Bernardino flying squirrel (Glaucomys sabrinus californicus), even though hundreds of papers about squirrels in general are published every year. Despite this [...]

    This Massive Squirrel Has Been Saved from Extinction

    Delmarva Peninsula fox squirrel

    It only took about half a century, but the once-rare Delmarva fox squirrel (Sciurus niger cinereus) now has a healthy population once again, placing it in a position to finally leave the protection of the Endangered Species Act (ESA). If that happens, this giant squirrel—which can reach an astonishing 75 centimeters in length—would join just [...]
