Eelgrass Genomic Vulnerability to Climate Change Across 23 Temperate Populations

Fisheries and Oceans Canada provides genomic data from a pooled whole-genome re-sequencing study of 23 eelgrass (Zostera marina) populations. The dataset includes over 500,000 SNPs mapped to a chromosome-level assembly, revealing six broad clades and genomic offset predictions under climate change scenarios. The data was published in 2024 and last updated in April 2026.

Use Cases

• Modeling genomic vulnerability to climate change based on SNP data and redundancy analyses.
• Analyzing population structure and gene flow across different ocean basins.
• Identifying conservation priorities for latent genetic diversity based on identified clades.
• Comparing genetic diversity metrics between Pacific, Atlantic, and subarctic populations.

Strengths

• Over 500,000 SNPs provide a high-resolution genomic basis for analysis.
• Data covers 23 populations across a broad geographic range from the Northeast US to Pacific Canada.
• Includes genomic offset predictions under two climate change projection scenarios.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
