Paws of polar bears sustaining ice-related injuries in a warming Arctic

Three polar bears walk across an icy landscape with paw prints zig-zagging across.

Polar bears in some parts of the high Arctic are developing ice buildup and related injuries to their feet, apparently due to changing sea ice conditions in a warming Arctic. While surveying the health of two polar bear populations, researchers led by Kristin Laidre from UW SAFS, found lacerations, hair loss, ice buildup and skin ulcerations primarily affecting the feet of adult bears as well as other parts of the body.

Bitter crabs…attitude problem or parasitic infection?

A needle is inserted into the underside of a pink-colored crab.

Bitter crab syndrome might sound like an attitude problem, but it’s actually a condition faced by two very valuable fisheries in Alaska: snow crabs and Tanner crabs.

We spoke to SAFS grad student, Aspen Coyle, about her research.

Clicks not bricks: A global assessment of the online trade of ornamental crayfish

A blue crayfish pictured in a small aquarium with rocks.

They may be small, but crayfish are mighty in other ways, one of them being invasive risk in areas where they are not natively found. Crayfish are increasingly being traded online for ornamental purposes, such as aquariums, and in a new study led by SAFS Professor Julian Olden, the first ever global assessment of the online trade in and associated invasion risk of freshwater crayfishes was conducted.

Uncovering parasites in one of the world’s largest fish collections

Housed in a set of World War II artillery bunkers on the outskirts of New Orleans is a surprising, and gargantuan, fish collection. Home to the largest collection of post-larval fish specimens in the world – 7 million to be precise – the Royal D. Suttkus Fish Collection at the Tulane University Biodiversity Research Institute (TUBRI) was the destination for a group of UW researchers over the summer.
