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 […]
Alaska’s North Slope is home to Arctic ground squirrels. Near the Atigun River their interlaced burrow network takes advantage of sandy soil. The burrows are so interconnected and the entrances so myriad that the scientists working there to decode Arctic ground squirrel mysteries carry a map denoting burrow entrance numbers so they can be certain […]
“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 […]
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
Arctic Ground Squirrel Videos The extraordinary life of the Arctic ground squirrel is described by dedicated scientists who study the handsome creatures. In videos:
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 […]
The results of my studies identified four species of fish, dominated by arctic grayling, burbot, lake trout and northern pike, two species of bird, mostly willow ptarmigan, but a few duck bones (species unidentified) were recovered as well. This is important because ducks are migratory species only found in the Brooks Range in warmer months […]
