Hibernating Arctic ground squirrels (Spermopilus parryii) at the University of Alaska at Fairbanks. This animal is the grand champion of all hibernators. It’s the only mammal that can drop its body temperature to below freezing. They hibernate for seven months. Females go in first, in August. Males follow a month later. They come out again to feed on tundra plants in May. Biologists at UAF have been studying the animal for 20 years, but still can’t figure out how this animal maintains a flat body temperature for all those months just above freezing. “You could put people into hibernation for space trips if you could understand it better,” said Franziska ‘Fran’ Kohl, one of the biologists here. “They also show symptoms of Alzheimers during hibernation.” She added that traumatic head injuries heal when in hibernation, another thing scientists are trying to figure out.

All prints by Joel Sartore are archival.

Framing and matting includes a satin finish black wooden frame, a 3” white acid-free matte, and plexiglass. The frames are custom made and can take 5 business days to be prepared.

Our canvas gallery wraps are professionally printed and stretched over a durable frame. This can take 5 business days to be prepared. They are finished with an open-style back with a hanger, and arrive ready to display.

Sizes shown are approximate. The sizes are in inches and denote the size of the image itself. Each image is printed with a white border, so the paper size is larger than the image size. If you need a print sized exactly, please let us know when you place your order. Custom sizes are also available. Custom orders take longer to fulfill than standard orders.

Signed prints may take longer if Joel is traveling, which is often, as he continues to add species to the Photo Ark.

All prints are created at the time of purchase. Because of this, we do not accept returns or exchanges for prints. The only exception is if the print is not up to our pristine standards. Any flaws must be brought to our attention within 5 business days.

Any applicable international customs fees are not included in shipping and handling. The recipient may be required to pay custom fees at the time of delivery if items are shipped outside of the US.
