A chromosome-level genome assembly of an endangered large carnivore, the wolverine, Gulo gulo gulo (Linnaeus, 1758)

A chromosome-level, haplotype-resolved genome assembly for a male wolverine (Gulo gulo gulo) spans 2,523.2 Mb and 2,288.4 Mb and includes both sex chromosomes.

• Why it matters: Existing wolverine references are less complete, limiting population-genetic and conservation analyses that depend on accurate chromosome-scale sequence resources.
• What they did: The study generated a haplotype-resolved assembly from a male wolverine, scaffolding 95.8% and 97.8% into 20 autosomal chromosomes plus sex chromosomes, and assessed completeness with BUSCO.
• The result: The assembly shows high completeness (BUSCO 98.2% and 88.9%) and yields 20,337 and 17,692 protein-coding genes, enabling improved population studies and conservation biology for this species.
