Siberian Hazel Genetic Diversity Across 20 Populations in South Korea

4,378 single-nucleotide polymorphisms from 161 individuals of Siberian hazel (Corylus heterophylla) quantify genetic diversity and connectivity. The dataset, authored by Tae-Young Choi and last updated in 2026, reveals low population differentiation and extensive gene flow across the Korean Peninsula. Demographic reconstruction suggests two population declines during the Late Pleistocene followed by recovery.

Use Cases

• Assessing genetic diversity and population structure based on SNP data from 20 populations
• Modeling gene flow and connectivity patterns across a geographic region
• Reconstructing demographic history, including population declines and recoveries
• Evaluating the impact of historical human-mediated movement on genetic patterns

Strengths

• Includes 4,378 genome-wide single-nucleotide polymorphisms (SNPs)
• Covers 161 individuals sampled across 20 distinct populations
• Has a clear open license (CC-BY-4.0)

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data is provided as a 407.9 KB DOCX file, which may require format conversion for analysis
