SCIOPS produced a dataset on the concentrations of phenolic metabolites in the Antarctic lichen Umbilicaria antarctica. Densitometric analysis (HPTLC) was used to measure usnic acid, atranorin, and gyrophoric acid levels in thalli of different ages. The data was last updated on February 20, 1989.
Use Cases
- Modeling the relationship between lichen age and secondary metabolite concentration based on the described age classes.
- Comparing the spatial distribution of usnic acid and atranorin within lichen structures, as mentioned for isolated rhizines.
- Analyzing the contrasting abundance patterns of gyrophoric acid versus usnic acid and atranorin across age classes.
Strengths
- Focuses on a specific Antarctic lichen species, Umbilicaria antarctica.
- Measures concentrations of three distinct phenolic compounds (usnic acid, atranorin, gyrophoric acid).
- Data is stratified by thallus age classes, allowing for age-related analysis.
Limitations
- Last updated 1989-02-20 23:59:59.999000; freshness should be verified.
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
