An international team of researchers, including Kristin Laidre, conducted a study involving genetic variability in polar bears. Read about the study in Animal Conservation.

Scavenging on stranded large whale carcasses may have aided polar bear survival through past interglacial periods, during which sea‐ice was limited and access to seals was reduced. Will whales play a similar role in the future as Arctic conditions change? To learn more, read the recent study led by PSC’s Kristin Laidre in the journal Frontiers in Ecology and the Environment.

The Washington Post covered new research findings on narwhal physiology and asked PSC’s Kristin Laidre what it will mean for the species in a changing Arctic. 

The US Fish and Wildlife Service recently released their Conservation Management Plan (CMP) for the polar bear. Required under the Endangered Species Act, the CMP outlines what must be done for a species to recover and avoid extinction. Kristin Laidre comments for the New York Times.

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.

Erica Escajeda and Kristin Laidre were part of an international team of researchers that studied polar bear maternity dens and compared current data with previously published data through the 1990s. Read the findings published in Polar Biology.
