Overview
- Peer-reviewed research in Molecular Biology and Evolution presents a chromosome-level reference genome for the Apennine brown bear.
- Whole-genome resequencing shows reduced genetic diversity and elevated inbreeding compared with Slovak and North American brown bears.
- Selective signatures appear at genes associated with lower aggressiveness, consistent with long-term culling of more aggressive individuals by people.
- The small, isolated central Italian population is considered critically endangered after historical declines tied to forest clearance and agricultural expansion.
- Authors warn that restocking or mixing with other populations could dilute variants that may help reduce human-bear conflict.
