The news source International Business Times, out of the UK, reports on findings recently published in Global Change Biology of a decades-long research study involving Beluga whales. Donna Hauser, Kristin Laidre, Harry Stern and colleagues examined changes in autumn migration timing of Beluga whale populations since the 1990s.
The publication Conservation Biology announced its awards for 2016 and PSC’s Kristin Laidre is the lead author of the paper that earned the second highest altmetric score, Arctic Marine Mammal Population Status, Sea Ice Habitat Loss, and Conservation Recommendations for the 21st Century.
Laidre led the collaborative effort which involved PSC colleagues Harry Stern and Eric Regehr (at present), along with other researchers from Canada, Greenland, Norway, Russia and other US institutions. Congratulations to Kristin and the team!

The UW Today reports on the open-access study recently published in the Journal of Applied Ecology by PSC’s Eric Regehr and a collaborative team, including Harry Stern. The team combined data collected on polar bear subpopulations with that of sea ice extent and identified ways to carry on subsistence harvesting with the least amount of negative impact already caused by habitat loss.
Recent research by Kristin Laidre and Harry Stern on the impacts of climate change on Arctic narwhals is published in Polar Biology. See the article in Conservation Magazine.

In search of the Northwest Passage, Captain James Cook was the first to actually probe and chart the ice edge north of Bering Strait. Polar Geography has published Harry Stern’s research of Cook’s exploration of the Arctic and how other expeditions fared in comparison, resulting in a history of sea-ice observations from Cook’s time to the present.
