June 10 2015, 9pm in Alaska, tune in to KAKM Science Wednesdays, Alaska Public Media, for Frontier Scientists’ ARCTIC GROUND SQUIRREL feature. Ground squirrels, described as cute furballs or the perfect yuppie pet, live unusual lives in the Arctic. They survive body temperatures below freezing and use a superpowered internalized clock to stay on schedule. […]
Two people are looking at a picture of the same dress on the same screen. When asked ‘What color is this dress?’ they might give entirely different answers. Some people see a white dress with gold trim. Others see a blue dress with black trim. Others see variations. The viral picture set people at odds […]
“They do their best to approximate a sphere,” Loren Buck explained as he removed the ground squirrel from its lab-made hibernaculum. Hibernating Arctic ground squirrels can sustain a core body temperature of just -2.9°C [26.78°F]. “It’s cold… Do you want to touch it?” Buck uncurled the animal carefully. “He knows he’s being handled, it just takes a […]
They survive colder core body temperatures than any other known vertebrate, sustaining a temperature below freezing yet not becoming frozen. They emerge from hibernation with clock-like accuracy
Arctic ground squirrels may seem like little more than a brief thrill for your dog on a hike up Flat Top, but scientists are convinced they’re worth a serious second look.
Biology major Brady Salli spends seven days a week in the vivarium making sure UAA’s arctic ground squirrels are fed, watered and, for those that are hibernating, tucked snugly into clean cotton batting. The kicker? He has to maintain a random schedule so the animals don’t “cheat” off of him. Professor Loren Buck, Department of […]
Laura Nielsen for Frontier Scientists – A grizzly bear chowing down on salmon, berries, ground squirrels, carrion, grasses and roots isn’t just hungry- he’s on a mission. During winter months while humans in cold climes are shoveling snow, most brown bears like the grizzly are sleeping. This isn’t ‘true’ hibernation; the bear’s temperature drops to […]
