Bryoria Lichen Phylogeny with Six Gene Regions from 71 Specimens

71 Bryoria lichen specimens from North America, Europe, and Asia were sequenced for six gene regions to examine infrageneric relationships. The study by Myllys, Leena reveals a recent diversification in section Divaricatae, estimated at around 5 million years old, and describes a new species, B. ahtiana. Data includes alignments and phylogenetic analyses from seven datasets prepared for maximum parsimony, likelihood, and Bayesian methods.

Use Cases

• Testing species delimitation methods based on inconsistent results from different gene regions mentioned in the description
• Analyzing phylogenetic relationships within the Bryoria bicolor/B. tenuis group using the provided six-locus dataset
• Studying recent evolutionary radiation patterns in section Divaricatae, which the description notes is young and diversifying
• Comparing topological congruence between the ITS gene region and other markers for species concept validation

Strengths

• Includes genetic data from six distinct molecular markers (ITS, IGS, mtSSU, Mcm7, GAPDH, Tsr1)
• Analyses are based on 71 specimens collected from three continents, providing a broad geographic scope
• Phylogenetic analyses were performed using three different methods (maximum parsimony, maximum likelihood, Bayesian) for seven datasets

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Some gene regions produced poorly resolved phylogenetic trees, indicating potential data quality challenges for certain analyses
