Lichen Metabolome Across European Regions and Seasons

Marta Pérez-Rodrigo's dataset characterizes the low-molecular-weight metabolome of the lichen Ramalina farinacea. It contains annotations for 187 small molecules from thalli collected across six European regions during winter and summer, using untargeted GC-MS. The data was published on figshare in May 2026.

Use Cases

• Identifying osmoprotective metabolite markers based on the described core of 12 shared metabolites.
• Modeling metabolomic dissimilarity drivers based on season, region, and climate-similarity groups mentioned in the results.
• Investigating homeoviscous adaptation patterns based on described shifts in glycerol, monoglycerides, and fatty acids.
• Analyzing pathway over-representation in alanine, aspartate, and glutamate metabolism as indicated in the discussion.

Strengths

• Contains annotations for 187 small molecules, providing a metabolome-wide view.
• Data is derived from a continent-scale reference across six European regions and two seasons.
• A compact core of 12 metabolites is shared across all sites and seasons, indicating robust signals.
• 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 primary file format is a 487.6 KB PDF, which may require extraction to access structured data.
