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.
