The Arctic Ocean is undergoing rapid transformation toward a seasonally ice-free ecosystem. As ice-adapted apex predators, polar bears () are challenged to cope with ongoing habitat degradation and changes in their prey base driven by food-web response to climate warming. Knowledge of polar bear response to environmental change is necessary to understand ecosystem dynamics and inform conservation decisions.

- Understanding the genetic structure of wild populations is crucial for conservation, especially with environmental changes affecting habitats.
- The study focused on the genetic diversity of greater white-fronted goose populations in Alaska, revealing significant genetic differences, particularly in mitochondrial DNA among the populations.
- Nonrandom mate selection and fine-scale resource use contribute to genetic divergence, emphasizing the importance of examining behavioral and social factors for understanding gene flow in these birds.
