Episode 31 Season 7: Polar Bears Leftovers, And Dog Judgments

A top predator that “wastes” food and ends up feeding an entire ecosystem? That paradox sits at the heart of our latest exploration into polar bear behavior and the hidden scaffolding of the Arctic food web. We unpack new research estimating that each polar bear leaves roughly 300 kilograms of edible remains annually—amounting to millions of kilograms across the region—and why those leftovers are vital calories for Arctic foxes, ravens, gulls, snowy owls, and even wolves. By focusing on blubber for maximum energy return, polar bears inadvertently act as providers in a landscape where every calorie matters, and we trace how shrinking sea ice threatens not just bears but the scavengers who depend on their kills.

From icy shores to living rooms, we then tackle a beloved belief: can dogs judge human character? A Kyoto University study with 40 pet dogs put that idea to the test using a generous-versus-selfish setup. The result: no reliable preference for the kind human, even after direct interaction. We break down what this means for canine social cognition, why food-based tasks may miss the mark, and how ethics limit what scientists can test. Rather than a simple moral radar, dogs may rely on a complex blend of context, prior reinforcement, and human cues that are hard to capture in a two-choice experiment.

Along the way, we share field notes from polar bear country, practical insights for interpreting your dog’s behavior without overreading the wag, and a clear view of how climate change reshapes energy flows you rarely hear about. If you care about wildlife science, animal behavior, or how small choices ripple through entire systems, this one offers fresh data and useful takeaways.
