Lichen Metabolome Across European Regions and Seasons

A continent-scale reference for the in-situ metabolome of the lichen Ramalina farinacea, collected across six European regions during winter and summer. The dataset, created by Marta Pérez-Rodrigo and last updated in May 2026, contains annotations for 187 small molecules identified via untargeted GC-MS.

Use Cases

• Identify seasonal metabolic markers based on GABA and mannose levels mentioned in the description.
• Analyze regional climatic drivers based on linoleic acid and arabitol patterns.
• Study homeoviscous adaptation mechanisms based on glycerol and fatty acid profiles.
• Investigate core metabolic resilience based on the compact core of 12 shared metabolites.

Strengths

• Contains annotations for 187 small molecules.
• Samples collected from six European regions across two seasons, providing spatial and temporal coverage.
• Identifies a compact core of 12 metabolites shared across all sites and seasons.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is very small (24.0 KB), indicating limited scope.
