Should your local government prioritize protecting natural habitats to ensure long-term wildlife health?

Researchers at North Carolina State University have completed a genomic survey of 76 black bears, revealing distinct genetic health differences between mountain and coastal populations. This study, published in the journal Genes, identifies lower genetic diversity and higher inbreeding among the state's coastal bear populations.

Why it matters

The findings reveal how landscape changes have restricted movement and isolated coastal bears compared to their mountain counterparts. This genomic data now provides a blueprint for wildlife officials to track bear origins and manage populations more effectively.

The team identified three distinct genetic clusters—two in the mountains and one in the coastal region—using a panel of single nucleotide polymorphisms, or SNPs, which act as specific genetic fingerprints. These markers were developed from whole genome sequences to distinguish regional origin.

The players

North Carolina State University

A public research institution that focuses on genomic science and wildlife ecology.

The details

Researchers generated whole genome sequences from DNA samples to catalog the genetic health of the populations. The resulting single nucleotide polymorphism panel—a set of specific variations in DNA sequence—functions as a genetic fingerprint to trace individual bears. Coastal bears exhibit reduced diversity because landscape alterations have curtailed their movement, whereas mountain bears maintain connectivity through geographical features that allow movement across state lines.

The study was published in the journal Genes on October 22, 2026.

The Tech Race

This study aligns with the conservation goals of the Pittman-Robertson Federal Aid to Wildlife Restoration Grant. It advances state-level wildlife management by providing genomic tools that surpass traditional, less precise tracking methods.

State wildlife officials will use the new genetic marker panel to assist in future field operations, including poaching investigations. These diagnostic tools allow authorities to verify the origin of bears more accurately when enforcing regional wildlife protections.

The takeaway

The research establishes a new genetic baseline for North Carolina black bears that officials will use to monitor population health in real-time. Wildlife managers now plan to collaborate with state authorities to integrate this SNP-based tracking into standard enforcement protocols.
