Epigenetic and Dietary Data for 152 Alaskan Coastal Wolves

152 Alexander Archipelago wolves were classified into terrestrial, marine, and mixed dietary groups using DNA metabarcoding and stable isotope analysis. The dataset includes 1,263 differentially methylated regions (DMRs) identified via EpiRAD sequencing, published by Aaron Schrey in 2026. It is hosted on figshare under a CC-BY-4.0 license.

Use Cases

• Identifying epigenetic biomarkers for marine resource consumption based on widespread hypermethylation patterns.
• Comparing genetic and epigenetic signals of population structure using diet-associated DMRs distinct from neutral genetic markers.
• Investigating links between dietary fatty acid intake and one-carbon metabolism through genome-wide methylation state.
• Developing ecological monitoring tools for predator diets using DNA methylation as an intrinsic marker.

Strengths

• Includes data from 152 individual wolves, providing a substantial sample size for analysis.
• Identifies 1,263 differentially methylated regions (DMRs) associated with diet, offering a detailed molecular profile.
• Dietary classification is based on two complementary methods: DNA metabarcoding and stable isotope analysis.

Limitations

• Row count for the underlying data tables is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is small at 53.2 KB, indicating limited scope and likely summary-level data.
