Lichen Metabolome Across European Regions and Seasons

187 small molecules were annotated from the lichen Ramalina farinacea, collected across six European regions in winter and summer using untargeted GC-MS. The dataset was created by Marta Pérez-Rodrigo and published on figshare in May 2026. It reveals a core of 12 shared metabolites and identifies seasonal and regional metabolic markers.

Use Cases

• Identify metabolic markers for climate regimes based on polyol and fatty acid profiles.
• Model lichen stress physiology based on annotated pathways like alanine, aspartate, and glutamate metabolism.
• Analyze seasonal metabolic remodeling using consistent markers like GABA and mannose for summer.
• Study homeoviscous adaptation patterns from glycerol and fatty acid levels across temperature gradients.

Strengths

• Contains 187 annotated small molecules from a continent-scale sampling.
• Data covers six European regions and two seasons (winter and summer), providing environmental contrast.
• Licensed under CC-BY-4.0 for open reuse.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is small (39.1 KB), indicating limited scope.
