Siberian Hazel Genetic Diversity and Population Structure in South Korea

4,378 single-nucleotide polymorphisms from 161 Siberian hazel (Corylus heterophylla) individuals sampled across 20 populations in South Korea. The dataset, authored by Tae-Young Choi and last updated in May 2026, quantifies genetic diversity, population differentiation, gene flow, and demographic history. It suggests high connectivity likely due to historical human-mediated movement.

Use Cases

• Assessing genetic diversity and population structure based on SNP data from 20 populations.
• Modeling historical gene flow and demographic changes based on inferred population declines and recoveries.
• Informing conservation strategies for Siberian hazel based on its genetic connectivity and diversity metrics.

Strengths

• Contains 4,378 single-nucleotide polymorphisms for genetic analysis.
• Based on a sample of 161 individuals from 20 distinct populations.
• Released under a permissive CC-BY-4.0 license for reuse.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The 14.5 KB file size indicates a very small dataset with limited scope.
