Petrocodon Plant Phylogenies and Scripts for Karst Habitat Study

Lihua Yang's 2026 study provides phylogenies and scripts for the karst-endemic plant genus Petrocodon. The 3.1 MB repository integrates genomic, morphological, geographic, and paleoclimatic data. Results support a predominantly non-adaptive radiation shaped by spatial opportunity and reticulate evolution.

Use Cases

• Reconstructing phylogenetic trees based on concatenation- and coalescent-based methods described in the study.
• Analyzing the role of neutral processes versus ecological adaptation in diversification based on integrated genomic and phenotypic data.
• Studying the impact of geographic isolation in karst habitats on species richness and phenotypic diversity.
• Modeling reticulate evolution and drift in a plant genus using the provided custom scripts.

Strengths

• Data integrates multiple evidence types: genomic sequences, morphological, geographic, and paleoclimatic data.
• Phylogenies are inferred using both concatenation- and coalescent-based methods for robustness.
• Repository is licensed under CC-BY-4.0, permitting open reuse and adaptation.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the study of a single karst-endemic genus.
