Squirrels in Arctic science

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. […]

“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 […]

How to catch an Arctic ground squirrel – for science!

At Atigun River, north of the Arctic Circle, the sandy soil is run through with an interlaced network of burrows. The Arctic ground squirrels which call those burrows home have encountered something mundane to you or me, but no-doubt wondrous to them: big tasty taproots, stunningly orange. Carrots! Trapping squirrels The carrots are bait, placed […]

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

Biological clocks: Where arctic ground squirrels meet ‘social jet lag’

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 […]
