- DOI：
- doi:10.5061/dryad.3fg5r56
- 摘要：
- Selective consumption of prey by predators, observed in many animals, is often attributed to optimal foraging. Consistent with this idea, brown bear

- 摘要：
- The Scandinavian brown bear went through a major decline in population size approximately 100 years ago, due to intense hunting. After bei
