Zoo-Based Studies

Our zoo and aquarium partners help us with research projects that would be impossible to conduct with polar bears in the wild.

Our fieldwork with polar bears takes us from Alaska to Svalbard and across the Canadian North, working in subzero temperatures and other Arctic conditions. But we’ve also discovered that, sometimes, critical polar bear questions can only be answered in a zoo setting — or through a collaborative effort involving wild and zoo bears (i.e., in situ and ex situ research).

The zoos, aquariums, and wildlife parks in our Arctic Ambassador Center network partner with us on key research projects. They fill knowledge gaps and answer basic questions, ultimately helping scientists better understand what polar bears need to survive in a rapidly changing Arctic.

Over the past two decades, studies with zoo partners have yielded invaluable insights, from documenting the polar bears’ hearing range to testing their energy use and how they find mates.

Reading a polar bear’s past in its fur

Scientists have long thought that polar bears grow fur once a year, in summer. But as a new study shows, polar bear fur can grow as early as February.
