Roldana Phylogenetic Trees for Spatial Biodiversity Analysis in Mexico

Mexico's biodiversity is analyzed using 159 phylogenetic trees for 54 species of the plant genus Roldana. The dataset includes 12 molecular phylogenies and 147 phylogenies constructed with taxonomic data to include all described Mexican taxa. It was created by Luis Morales-Garduño and last updated on April 20, 2026.

Use Cases

• Assessing the robustness of phylogenetic endemism indices based on phylogenies with varying levels of completeness.
• Comparing molecular and taxonomy-based phylogenetic hypotheses for biogeographic understanding.
• Evaluating the impact of polytomies and branch lengths on spatial phylogenetic analyses for conservation planning.

Strengths

• Includes 159 distinct phylogenetic trees, enabling comparative analysis.
• Focuses on a specific genus (Roldana) with 54 species distributed across 89 grid cells in Mexico.
• Provides 12 molecular phylogenies and 147 phylogenies incorporating taxonomic data for completeness.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
